Cataracts: Treatment, Procedure, Cost and Side Effects

What is the treatment?

Cataract is a type of eye disease. In this ophthalmologic condition, the lenses become cloudy and opaque and this causes a disturbance in the vision of the person. Cataracts are common, often develop slowly and can affect one or both eyes, especially when aging.

Cataracts are formed when protein and water accumulate in the eyes. As people age, around 50-60, these proteins start to build up and accumulate as clouds, thus blurs the vision. Cataracts may also develop due to other medical conditions, like diabetes, from intake of medicines such as corticosteroids or diuretics and also due to ultraviolet light, or radiation. These are called secondary cataracts. Cataracts can also be inherited right from birth or due to some injury.

The most prominent symptom of cataract is blurred cloudy foggy, or filmy vision. Changes in color reception and nearsightedness are two common symptoms in elderly people. People face glare problem during the day and night, perceive double vision and have troubles with lenses and eye glasses.

In the early stages of cataract, vision can be improved using new glasses, strong bifocals, magnification, appropriate lighting or other visual aids. This way, further cataract can be prevented. But in the later stages, surgeries are performed to remove cataract. Cataract surgery is simple and painless and very successful in restoring vision. There are three standard forms of surgery for cataracts – a standard monofocal intraocular lens (IOL), a multifocal intraocular lens (IOL) or an accommodating lens.

How is the treatment done?

In order to diagnose cataract, the doctor will go through the medical history and recommend several diagnostic tests. These tests include visual acuity test, slit lamp examination and retinal examination. A special device called an ophthalmoscope is also used to examine the lens for signs of a cataract.

Cataract can be treated in two ways, depending on the severity of the condition. In the initial stages, the blur or fuzzy vision can be cured with the help of glasses and contact lenses. In this case, no surgical operation is needed. If glasses fail to clear to vision impairment, then surgery is the only method to remove the protein cloud formation on the retina and clear the vision. Cataract surgery is done as an outpatient basis and is simple and painless. In cataract surgery, the protein clouded lens is removed and replaced with a clear artificial lens. This artificial lens is called an intraocular lens and is positioned in the same place as the natural lens. It remains a permanent part of the eye. If both eyes have cataracts and surgery needs to be done on both of them, the surgery on the second eye is generally planned at least a week after the first eye. This is done to help regain comfort and proper vision in the first operated eye. After operation, the person may feel discomfort for a few days but this goes away in a week’s time.

Who is eligible for the treatment? (When is the treatment done?)

People should immediately consult a doctor when they develop symptoms of cataract or any visual problems or disturbances. Sudden vision changes, such as blurred or foggy vision, double vision or flashes of light, sudden eye pain, or sudden headache need to be supervised by ophthalmologists.

Who is not eligible for the treatment?

Surgical operations for cataract or blurred vision may not be needed if visual aids like glasses and contact lenses can improve vision. First or earlier stages do not require much treatment and cataract can be prevented from worsening vision further.

Are there any side effects?

There are some complications associated with cataract surgery. It carries a risk of infection and bleeding. Cataract surgery increases the risk of retinal detachment and endophthalmitis. People face decrease in vision along with pain in both the cases. Their vision gets blurred along with unilateral visual field defects, flashes of light, or floating spots. People may also face less serious but more common problems like corneal edema and cystoid macular edema. These occur because of persistent swelling at the front of the eye in corneal edema or back of the eye in cystoid macular edema. Even after months or years after successful cataract surgery, people may face problems like vision deterioration or problems with glare and light scattering. This is called posterior lens capsule opacification which occurs due to thickening of the back or posterior capsule surrounding the implanted lens. When small parts of natural lens remain I the eyes after removal, cells start growing and cause this defect.

What are the post-treatment guidelines?

Healing generally occurs within eight weeks, which is a comparatively short time period. Patients are advised to be more cautious and avoid straining their eyes for at least one month post operation. Patients are also advised to use eye shields and eye patches for some times after the surgery to avoid any complication. Eye drops according to doctor’s advice must be taken regularly. People must be extra cautious to prevent water, soap and pressure on the eyes.

How long does it take to recover?

Cataract surgery is done on an outpatient basis, that is, the patients go home on the day of surgery itself. Healing generally takes a short period of time and is around eight weeks. On the initial days, people feel discomfort but this goes away as the person gets more used to the artificial lens. Vision also gets clearer with passing days, unless there be other complications or eye related problems.

What is the price of the treatment in India?

Initial stage cataract which do not require surgical operations are less expensive as these can be treated with glasses, contact lens use etc. But, cost of surgical operations for cataract treatment is high and involves around Rs 1,50,000- RS. 2,00,000/-.

Are the results of the treatment permanent?

Unless there be any other eye diseases like glaucoma, treatments for cataract are permanent. Cataract surgery is simple and painless and yields permanent results with rare complications. After cataract surgery, people get clearer vision and blurs and clouds from the eyes disappear.

What are the alternatives to the treatment?

There are alternative ways to treat cataract. Apart from surgery, ayurvedic treatment also helps to reverse cataract. Taking proper intake of balanced diet will also help cure cataract. In Ayurveda, cataract is known as timira or linga nasha. Early stages of cataract can be effectively treated with Ayurveda. Foods like eggs, fish (fatty fish like salmon) , green leaves, fruits like avocado, bell peppers, carrots etc. help to reverse cataract and prevent it. Changes in the lifestyle like increasing light in the house, limiting night driving, keeping diabetes under control also helps to prevent cataracts and provides longevity of vision.

Eye Care During Diabetes!

Eye Care During Diabetes!

Diabetes is a condition characterized by an elevated level of the blood glucose due to the insufficient production of the Insulin by the Beta cells of the pancreas. The high blood glucose level can also be an outcome of the inability of the body cells to utilize or respond to the insulin produced - a condition termed as Insulin Resistance.

Today, Diabetes has become a raging problem affecting almost every second individual, irrespective of their age, sex or ethnicity. What is even worse is the fact that the metabolic disorder affects a host of the vital body organs including the eyes. In many diabetic patients (diabetes left unmanaged and uncontrolled for long), the high blood sugar or Hyperglycemia can give rise to many eye complications such as:

  • Diabetic Retinopathy (Hyperglycemia that triggers progressive damage of the blood vessels of the retina that can eventually even lead to blindness).
  • Incidences of Cataract (a condition that causes clouding of the clear eye lenses affecting one's vision) and Glaucoma (a severe eye problem that results from the damages to the optic nerve of the eye) are on a rise in diabetic patients.

Thus, it becomes essential to carry out the preventive measure to deal with diabetes-related eye problems and the associated complications.

Protecting the eyes from Diabetes

  1. Controlling Diabetes: Amongst different eye care or preventive measures, foremost is to make sure that diabetes and the blood glucose level are within control. A glucometer can help to monitor the blood glucose levels at home. Regular lab tests for Fasting and Post prandial(FBS, PP2BS) blood sugar tests should be done at a frequency advised by treating physician along with HbA1c. Eliminating the underlying factor can work wonders to avoid the various eye problems resulting from diabetes.
  2. Regular eye-checks: People with diabetes need to be careful. Consult your family physician or a specialist at the earliest for discomforts and symptoms such as a headache, watery eyes, blurred, distorted or double vision. Regular eye-checks and screening tests are equally important to safeguard the eyes from the harmful consequences of diabetes.
  3. Keep a check on other medical disorders: Conditions such as Hypercholesterolemia (elevated levels of blood cholesterol), high blood pressure, along with diabetes, are the worst nemesis that can result in a myriad of eye disorders. Make sure the blood pressure is within the control (to avoid complications, try to maintain a blood pressure below 140/80) and so is the level of bad cholesterol or LDL (Low-density lipoprotein).
  4. Keep your body moving: Exercises and physical activities (morning or evening walks, jogging) can play a pivotal role in keeping diabetes under control, thereby shielding the eyes from problems such as cataract, glaucoma. Keeping the body weight within the healthy and recommended range can also work towards managing the blood glucose level.
  5. Healthy dietary modifications: Diabetic patients should be careful with their choice of foods. Dark chocolates, lean meat, whole grains, fish, cinnamon, turmeric, fruits and vegetables such as broccoli, blueberries, spinach, walnuts, sweet potatoes, asparagus, apricots, apples, to name a few are healthy options for a diabetic patient.
  6. Smoking can spell doom for the eyes and is best avoided.

Cataract - How to Reduce Your Risk?

Cataract - How to Reduce Your Risk?

We all have only a pair of eyes, so it is imperative that one understands the importance of vision. When the normally clear lens of one’s eye becomes clouded, the condition is known as cataract. A person suffering from cataract finds his vision to be hazy, discoloured and blurred somewhat like looking outside a frosted window. It causes difficulty in reading, driving a vehicle or seeing the familiar expression on a loved one’s face.
It is a silent killer of vision and initially magnification and lighting in addition to vision aids are helpful, but eventually a surgery becomes imminent. 

The exact reason for cataract are debatable, but one can take measures to protect oneself, boost one’s eyes’ defence mechanisms, and protect them from harmful elements. Ultra violet (UV) light has been correlated with incidents of cataract and has a damaging effect on one’s eyes. This requires one to wear sunglasses that block ultraviolet B (UVB) rays when one is outdoors. Smoking also increases the risk of cataract thus giving one another reason to stay away from active as well as passive smoking.

One must include antioxidants as zeaxanthin, vitamin C, lutein and vitamin A in daily diet to counteract with the daily damage. The addition of a variety of fruits and vegetables to one’s diet ensures that one is getting many vitamins and nutrients. The health of the eyes can be maintained with fruits and vegetables as they have many antioxidants. One must go for eye examination to ophthalmologists in a time bound and regular manner so to detect the onset of cataract at the earliest.

One must maintain a healthy weight by reducing the calorie intake. Excessive consumption of alcohol also increases the risk of cataract. If one is suffering with other health conditions like hypertension and diabetes, it becomes all the more important that one must follow the treatment plan diligently. The exposure to ionizing radiation like X-rays and cancer treatment via chemotherapy increase the risk of cataract.

Cataract develops when aging or injury changes the tissue that makes up one’s eye's lens while some cataract are due to inherited genetic disorders causing other health problems. In some cases eye conditions, medical conditions such as diabetes, long term usage of steroids, trauma or past eye surgery also leads to cataracts.

As one ages, the eye lenses become less flexible, less transparent and thicker. Ageing causes break down and clumping together of tissues within the eye lens leading to clouding small areas within the lens. As the cataract continues to develop, the clouding becomes denser and involves a greater part of the lens. Thus, although one cannot prevent cataract, but if one takes the above mentioned steps, then he can reduce the risks of getting it. If you wish to discuss about any specific problem, you can consult an Ophthalmologist.

Cataract - Factors That Put You At Risk!

Cataract - Factors That Put You At Risk!

Cataract usually affects people who are above 40. It is a blurring of the eye’s lens, which lies at the back of pupil and iris. It is the most usual cause behind the loss of vision for people above 40. Research also states that it is a major cause of blindness in the world.

Types of cataracts:

  1. Subcapsular cataract: People who are diabetic and those are taking high steroids are more prone to subcapsular cataract. In this type, the cataract develops at the back of the lens.
  2. Nuclear cataract: A nuclear cataract is related to aging. It usually affects the central portion of the lens of the eye.
  3. Cortical cataract: It is a white opacity, which begins from the periphery of the lens and spreads up to the center of the lens in a spot-like manner. It usually affects the cortex of the lens.

Symptoms:

  1. In the beginning, cataract affects a small portion of your eye and affects your vision.
  2. Your vision gradually gets blurred.
  3. Too much exposure to the light might cause glare.
  4. In nuclear cataract, you may notice a short-lived improvement of your near vision.
  5. In subcapsular cataract, you cannot notice any symptoms in the initial days.

Cause of cataract:
The lens inside our eyes acts like a camera and it is made of protein and water. The protein helps in keeping the lens clear. But with aging, the protein may start to form a lump, which causes cloudiness in the eye area. With time the cataract spreads all over the lens and creates more cloudiness, which ultimately leads to blindness. The factors which usually trigger cataract are

  1. Age
  2. UV rays from sunlight
  3. Obesity
  4. Hypertension
  5. Smoking
  6. Consumption of high dosage steroids medicines
  7. Statin medicines
  8. History of eye inflammation or any eye injury
  9. History of eye surgery
  10. Too much consumption of alcohol
  11. Hormone replacement therapy
  12. Family history of cataract

Prevention of cataract:
It cannot be guaranteed whether cataract can be prevented or not. A study shows that cataract is caused due to the oxidative changes in the lens of the eye. Nutrition studies have shown that consuming vegetables and fruits, which are high in antioxidants, may help in preventing cataract. Dietary intake of vitamin E, carotenoids lutein, and zeaxanthin from supplements and food items can decrease the risk of developing a cataract. Sunflower seeds, spinach and almonds are good sources of vitamin E. Kale, spinach, other leafy green veggies are the good sources of zeaxanthin and lutein. Food items that contain Omega-3 fatty acids and vitamin C decrease the chances of cataract.

Last, but not the least, when you step out, always wear a sunglasses, which has the ability to block UV rays. If you wish to discuss about any specific problem, you can consult an Ophthalmologist.

Cataract and Phaco Surgery - How It Helps?

Cataracts are a common eye problem experienced by the elderly. In some cases, babies may also be born with cataract as a congenital defect or it may develop as a result of conditions such as diabetes. Cataracts can affect one or both eyes and is characterized by the clouding of the lens in the eye. This can make it difficult to see clearly and if not treated in time can lead to blindness.

Common symptoms of cataract include:

  1. Blurred vision
  2. Nearsightedness
  3. Changes in the perception of colour
  4. Night blindness
  5. Increased sensitivity to glares
  6. Double vision

An eye examination is the first step to diagnosing cataracts. To confirm a diagnosis the doctor will also dilate the pupil to check the lens. Most cataracts can be easily treated with surgery. This surgery involves the separation of the cataract from the lens and its removal after which an intraocular lens implant is placed in the eye. In cases where this cannot be used, corrective contact lenses or glasses will need to be used. One of the most popular methods of cataract surgery is known as phaco surgery or phacoemulsification.

This surgery involves making two, small incisions on the eye where the cornea meets the sclera. This is then used to create a circular opening in the lens through which a probe is inserted into the eye. Sound waves or laser is then used to break the cataract into small pieces. This is then removed from the eyes and an intraocular lens implant is put in its place. Stitches are rarely required for this surgery and it is usually performed as an outpatient procedure while the patient is under local anaesthesia. When treating cataract, both eyes are usually not addressed simultaneously.

This surgery is usually pain free. The operated eye may be bandaged overnight and the patient will be given a protective eye shield to be worn for a week. The doctor will ask you to get a check up 2-3 days after the surgery where they can evaluate the clarity of the lens, overall health of the eye, eye pressure and visual acuity.

Cataract surgery is generally considered to be a safe surgery but like any other surgery there are risks involved. Some of the possible complications of this type of surgery include:

  1. Pain and redness of the eye
  2. Vision problems
  3. Swelling of the eye
  4. Discharge from the eye
  5. Flashes or floaters in the patient’s vision 

    If you wish to discuss about any specific problem, you can consult an ophthalmologist.

All About Cataract Surgery

All About Cataract Surgery

A cataract is defined as a clouding of lens in the eye where your vision gets blurred. A cataract affects the eyes, when light that passes through the lens prevents a clearly formed image from reaching your retina. The disease is very common and usually, develops as your eyes age or due to any injury caused to the tissues that cover your eye's lens.

Types of cataracts:

  1. Senile Cataract: This is the commonest of all. It is age-related clouding of the lens. It can affect the near or distance vision and can also cause glare and change in glasses power.
  2. Secondary Cataract: It can be developed after surgery for other eye problems like glaucoma and other health conditions such as diabetes.
  3. Traumatic Cataract: It can develop many years later after an injury caused to your eye.
  4. Congenital Cataract: As the term explains, the disease may be inborn or some children might develop it at a later stage which often affects both eyes. 
  5. Radiation Cataract: It can form after you are exposed to some form of radiation.

A cataract surgery involves the extraction or cleaning of the cloudy lens, which is then replaced by a clear artificial lens.

Why does it happen? 

There are lenses that lies behind our iris and pupil which act much like a camera lens. It helps concentrate light onto the retina at the back of our eye to form a sharply defined image. Besides, the lens also helps our eyes to adjust focus and allows us to see things clearly both far away and up close. The lens is composed of protein and water where the protein is arranged in a manner to keep the lens clear thereby letting light pass through it. 

However, as we grow old, some of the protein starts to become thick and cloud a small lens area. This is known as a cataract. With the passage of time, it may inflate and cover more of the lens, making it difficult for us to see.

Besides, there are other causes of cataract such as smoking, addiction of alcohol, prolonged sunlight exposure, to name a few. 

When should you opt for a cataract surgery?

Believe it or not, but till date no eye drop or medication has proven to reverse or prevent the formation of a cataract. If a cataract is affecting your nearsightedness or alteration in your prescription, then new prescription eyeglasses may help to better your blurred vision. However, the only treatment for a cataract is the surgical removal of your natural lens. And, most eye doctors recommend this surgery only when the problem becomes severe and starts hampering your day-to-day activities, such as studying or driving at night.

If you would like to consult with me privately, please click 'Consult'.

Cataract surgery is a procedure to remove the lens of your eye and, in most cases, replace it with an artificial lens. Normally, the lens of your eye is clear. A cataract causes the lens to become cloudy, which eventually affects your vision.

Cataract surgery is performed by an eye doctor (ophthalmologist) on an outpatient basis, which means you don't have to stay in the hospital after the surgery. Cataract surgery is very common and is generally a safe procedure.

How a cataract affects your vision

Cataract surgery is performed to treat cataracts. Cataracts can cause blurry vision and increase the glare from lights. If a cataract makes it difficult for you to carry out your normal activities, your doctor may suggest cataract surgery.

When a cataract interferes with the treatment of another eye problem, cataract surgery may be recommended. For example, doctors may recommend cataract surgery if a cataract makes it difficult for your eye doctor to examine the back of your eye to monitor or treat other eye problems such as age-related macular degeneration or diabetic retinopathy.

In most cases, waiting to have cataract surgery won't harm your eye, so you have time to consider your options. If your vision is still quite good, you may not need cataract surgery for many years, if ever.

When considering cataract surgery, keep these questions in mind:

  1. Can you see to safely do your job and to drive?
  2. Do you have problems reading or watching television?
  3. Is it difficult to cook, shop, do hardwork, climb stairs or take medications?
  4. Do vision problems affect your level of independence?
  5. Do bright lights make it more difficult to see?

Risks

Complications after cataract surgery are uncommon, and most can be treated successfully.

Cataract surgery risks include:

  1. Inflammation
  2. Infection
  3. Bleeding
  4. Swelling
  5. Drooping eyelid
  6. Dislocation of artificial lens
  7. Retinal detachment
  8. Glaucoma
  9. Secondary cataract

Loss of vision

Your risk of complications is greater if you have another eye disease or a serious medical condition. Occasionally, cataract surgery fails to improve vision because of underlying eye damage from other conditions, such as glaucoma or macular degeneration. If possible, it may be beneficial to evaluate and treat other eye problems before making the decision to have cataract surgery.

Cataract And Refractive Surgery: What Is The Difference?
Good morning friends.

I m Dr. Harshavardhan Ghorpade from Fortis hospital Vashi, department of visual sciences. And Saroj Speciality Eye Clinic Vashi. I have done my MS. FRCS and I m a cataract, cornea and a refractive eye surgeon. You can contact me and know more about me through lybrate.com.

Today I m going to talk to you about one very important topic which is of interest to one and all i.e. cataract and refractive surgeries, the recent advances in these surgeries. Let me first start by telling you what is cataract surgery? In cataract surgery the procedure is to remove the opaque lens of the eye which is called a cataract and replaced it by a nice clean artificial lens so that a patient can see again. While refractive surgery is something where we do refractive correction i.e. correction of power of the glasses either by the laser or by a surgical procedure. Both the things can be combined to ultimately give clear vision to the patient. So let s start by starting with the recent advances in the cataract surgery. Well today cataract surgery has been sophisticated by doing procedures using ultrasound phaco probe which is about 2.2mm in size and it can be lesser of up to 1.8mm as well. We can do microincision cataract surgery through these probes. As a result of which we don t require any anesthesia, any stitch and any blood coming out during surgery. During surgery we enter the eye with a very small opening and with the help of this ultrasound probe the emulsify or break the cataract into small pieces and then it is absorbed into the system of the machine, this is then replaced by a very small foldable lens. The lenses are of various types. They are usually monofocal, multifocal, or cylindrical. When we use monofocal lens we try to give you correction for distance so that most of the vision is good without glasses. When we use multifocal lens which is necessary to be put in both the eyes we can give you distance as well as near vision and when we use a toric lens we try to correct your cylindrical power as well. So ultimately by doing cataract surgery we not only remove the cataract but we also correct the glasses power of the patient so the patient can see very well without being too much dependent on the glasses. Apart from the various types of lenses we have now different types of machines which do the surgery. As I said micro-incision surgery is possible by using phaco probe but nowadays we are using laser as well to do the surgeries. Laser was a common term used in public to know or to talk about phacosurgery but today actual laser can also be used to do the surgeries. Although it is very expensive as well as time consuming. So ultimately if we have a good surgeon or experience surgeon micro incision phaco surgery is the surgery of choice even today and with the various type of lenses that available we can get rid of glasses as well apart from removing cataract. Now coming to the refractive surgery. Refractive surgery means removal of power of glasses doing a procedure on the eyes, this is usually done on the surface of the eye using a laser. What we do over here is laser surface ablation of the cornea which can lead to removal of glasses without doing any type of incision any cut or any kind of trauma to the patient or lots of tissue. So this a bladeless procedure and the patient is absolutely comfortable during the procedure and he may have some discomfort in first three or four days but overall at the end of the week he is absolutely normal as he was before without his glasses. This is one of the recent advances of bladeless procedures in laser surgeries. The other advances that we are doing nowadays is in very high refractive power say a power of more than seventeen and eighteen we introduces a special lens which is called as ICL which is put inside the eye without removing the cataract. This lens is like a contact lenses that sits on the lens i.e. given to us by nature. As a result of which the power which is there say e.g. patient with minus eighteen end up with the power which is close to zero and he would be again not dependent on his thick glasses. So this is another advanced that is occurred so that we can correct even the higher refractive errors. So overall if you look at the cataract and the refractive surgeries today we are doing very good sort of very advanced sort of treatments to all our patients which start with the removal of cataract, putting a lens of different types, we can do laser procedure over it to get rid of glasses. We can also put intraocular contact lenses, called ICL, which helps in removal of numbers with high powers and so at the end of the day our patients seems very happy and satisfy with all these results that are coming with modern advancements in cataract and refractive surgeries.

I hope you have understood the topic and if you have any more queries you can get back to me on lybrate.com.

Cataract Surgery
Main Dr Rajeev Gupta ek eye surgeon hu. Meri clinic, Om Eye Centre, jo ki Vasishali, Ghaziabad me siddh hai. Aaj me apko Cataract Surgery k baare me batana chahunga.

Cataract, jise hum motiyabind bhi kehte h, ankho ki wo beemari hai jisme aankho k lense ki transparency dheere dheere kam hone lagti hai aur isse ankho ki roshni kaafi kam hojati hai. Iska ilaaj cataract surgery he hai. Isme koi dawaiya kaam nahi karti hai. Cataract surgery me ankho k defective lens ko nikal kar artificial lens laga dia jata hai, jisse hume fir se dikhna shuru hojata hai. Aaj kal cataract surgery ki latest technique ka naam Phacoemulsification hai. Isme hume ek chote se cheere se phacoe probe ko ankh k ander dala jata hai. Ye motiye k, yani cataract k defected lens k chote chote pieces ko pighla k bahar nikal deta hai. Aur fir usi cheere se artificial lens ankho k ander laga diya jata hai.

Jo lens ankho ke ander lagaya jata hai, use hum mukhya roop se 2 tarah se divide kia ja sakta h;

Unifocal lens
Multifocal lens
Unifocal Lens: Jese ki naam se pata lagta hai, unifocal lens ek point pe focus banata hai. Suppose, agar humara lens door k object pe focus bana raha hai to nazdeeki cheez saaf nazar nahi aegi. Aur agar pass ki object pe focus bana raha hai to door ki cheezein saaf nazar nahi aegi. Islie is lens ke sath hume chashma lagana he padega, jo ki hume patients ko pass ki nazar ka chashma lagana he padta hai saaf dekhne ke lie.

Multifocal Lens: Multifocal lens 2-3 jagah pe focus bana sakta hai. Aur iski madad se hume nazdeek or door, dono theek se dikhai de sakta hai. Lekin Multifocal lens has some disadvantages over Unifocal lens. like;

Multifocal lens me hume image ka contrast kam milega in comparitive to Unifocal lens.
Multifocal lens me Glare and Halos dikhai dene ke zada chances hote hai
Konse patients ko Unifocal lens chahie or konse patient ko multifocal lens chaie, ye patients khud decide kar sakte h, according to their choice and work. Jin patents pe operation se pehle he cylindrical number zada hota hai, un patients ko focus banane k lie aise lens ki zarurat hoti hai jinme cylindrical power ho. Aise lens ko hum Toric lens bhi kehte hai.

Yani ki aise patients k liye, Unifocal toric lens ya fir Multifocal toric lens he zada acche maane jate hai jinko ki wo choose kar sakte hai.

Cataract surgery k results aj ki tareek me bohot acche hai. Lekin ultimate visual gain after cataract after the sugery depends on the condition of the eyes before sugery and how the surgery works on the patients.

Thank you.

Cataract: Vision Disorder
Causes, prevention, and treatments for Cataract

I am Dr. Sunita Lulla Gur, a senior eye specialist at Accuvision Eye Centre and AcuVision center. It has been long that people wonder, why we see less with ageing. Of which, ageing is itself a problem of many disease, or may be degenerative changes which are taking place in a body, of one, cataract is an important thing that happens. Now let s see what is cataract. Now when we see the complete structure of the eye, this is the cornea; then you have a natural lens, which is situated over here, and then we have the retina. So whenever the degeneration, normally when we see, the lens, which is more clear, okay? Now, what happens , with ageing, this degeneration of the proteins which are there in the lens, and it leads to opacification.

Now when we look into this, this is opacification of the lens which is happening. Now because of this opacification, what happens is, the natural clarity of the lens is lost, and then we see through this haze which is there. So this reduces, or leads to the diminishing of vision, or blurred vision. So, this condition is called as cataract. Now cataract can be of many types, and depending on the stage, your vision will be affected. Sometimes what happens in early cataracts, you will have little bit blurred vision, but you can cope up with your daily day to day life. There are different types of cataract; age-related, in children also we have seen, which is since birth and which is called as congenital cataract.

Traumatic cataract, it means, whenever there is injury to the eye, then it can lead to traumatic cataract. Or sometimes, drugs; there are some kind of drugs which can cause cataract, like if you are on, long term on steroids, or other drugs, then it can lead to cataract formation. So keeping that in mind, you should always have your regular eye check up, once you are at the age of 40 or 50 years old. In Indian scenario, as we are a tropical country, too much of sunlight and UV radiation, the chances of cataract formation in Indian scenario is much higher than the counterpart in American scenario which we have seen. Now coming to, when should I get the cataract surgery one? Now when we say that you have cataract, one should not panic, because it is a normal ageing process which is happening; and surgery is the only treatment option available, as there are no drops or drugs or oral medication available to prevent it. Yes the role of anti-oxidants and good healthy diet is definitely there, to prevent early onset of cataract, okay? Now coming to the treatment or the preventive part.

Now how can you prevent cataract? As I already said, it is an ageing process, nothing can be done, but still, get a regular eye check up, have a healthy diet, including greens, reds, and yellow vegetables in your diet. Take some, well, you can include some almonds, and walnuts in your diet. These are all antioxidants which can delay the degenerative process. Now another thing is, as I said, there are no drops etc, so there is no need to put any drops for that. Sometimes people do take over-the-counter drops, many say that these are the drops which will be able to reduce the cataract, but then nothing happens. Now when can one get the surgery done? Now we have seen that surgically, it is one of the safest procedures to get done.

Nowadays with technology, so many good machines are available, the evaluation protocols have improved, what are seeing. So nowadays we do laser surgery, microincision surgery which is the key-hole surgery, through a, very small incision, that is made; and then cataract is emulsified and removed. Now, because we make a very micro hole surgery or a very small hole surgery, the wound healing is very fast. Now the techniques which are available to remove cataract is, one is laser, where we make a very small laser cut over here, where no blade is used, and a small phaco emulsification, for objects like the tip of this pen, if you see, it is entered, and whole of this cataract which is there, is emulsified. The cataract which is there is emulsified, and intraocular lens is implanted, and then the wound healing occurs, and the next day, or within 2 to 3 days, you are back to your normal work.

You have to take some precautions, which we will explain to you later. So this process is called as laser technique. Then we have another technique which is microincision, which is a very small key hole that is done, around 1.8-2 mm, through which the probe goes inside, it emulsifies the cataract, the cleaning is done and then the lens is implanted. The 3rd technique is phacoemulsification, where again, the incision size is slightly more than the microincision hole, but still it can be moved, through a small incision and the wound healing is faster. So, well, what was happening in the initial days, we were making incisions of this size, to this size, but now the incisions are hardly around 1.5 to 3.5 mm, which helps in healing process. It does not induce any number, and again the intraocular lens which is implanted, it is implanted as according to your eye power, so that most of the time, it will help you to get rid of glasses for distance, but for reading, you will require some glasses, for reading.

There are different types of intraocular lenses to be implanted, depending on the need of the patient, the profession of the patient; after discussion with the doctor, one can decide, what kind of lenses one can go for. Now, after care treatment of cataract if we look, it is not very hard. Only, well, some precautions you have to take, like no water should go inside the eyes, no rubbing of eyes. These are the two main precautions to be done. Otherwise you can carry forward your daily routine as you were doing before. Regarding what can be done, after, as in, preventive, if we say, there are many patients who come an ask me, Doctor, how can I prevent cataract? , so I say to them, that as I cannot prevent cataract in my eyes, how can I suggest? But still, as I already said, good eating habits.

Smoking is again, one of the causes of cataract early. So do not smoke, or if you are smoking, quit smoking or reduce it. Third, again, if you are on UV exposure lights too much, like working in sunlight, always wear protective glasses, so that the UV radiation does not fall directly in your eyes, and then the amount of cataract can be reduced. If you all do not take any steroids on your own, always consult a doctor before you start steroids. So these are the precautionary things which can prevent cataract, from happening. And once you develop, you should be seen by an ophthalmologist. Get your eyes checked and then decide with your doctor that when you should get your surgery done.
