Cataract Surgery - Treatment, Procedure And Side Effects

What is the treatment?

Cataract surgery is the process of the removal of the natural lens of the human eye, also termed as the crystalline lens. This process is performed when the one or both the eyes have developed an opacification, commonly known as a cataract. The metabolic changes in the crystalline lens lead to the development of cataract with the passage of time. As a result, the eyes lose their transparency which in turn cause impairment and even complete loss of vision. Most patients experience the first symptoms of cataract as a strong glare from light sources in the morning and small light sources in darkness. It is also marked by reduced acuity when there is low light. During the cataract surgery, the affected natural lens is taken out and replaced with a high-quality synthetic lens for restoring the transparency of the lens. There are two types of procedures of cataract surgery used all over the world. The first process involves phacoemulsification while the second one is extracapsular cataract extraction. In most of the surgeries, the intraocular lens is inserted. The cataract extraction with the aid of intracapsular cataract extraction is suspended by the Phaco and therefore, it is rarely performed all over the world.

How is the treatment done?

The cataract surgery takes about an hour, and it doesn’t cause much discomfort among patients. During the process, the eye surgeon first numbs the eye with the aid of an anaesthetic. This suggests that you will remain awake during the process. If you are very anxious, the doctor would also give you medicine for relaxing. Then the surgeon would make a small incision in the front part of the eye. Then a specialised equipment would be used for breaking the cataract and then, suck it out. The new lens is then inserted which can be made of silicone, acrylic or plastic. In most cases, the intraocular lens is used after the removal of the natural lens. The implanted lens is then inserted through the incision within the capsular bag present in the posterior chamber. Sometimes, it may be required to opt for a sulcus implantation owing to the presence of the posterior capsular tears or zonulolysis. Then the incision is closed, and the doctor would then sew the incision with stitches. The cataract surgery is a simple process, and it is widely performed all over the world to improve the power of vision among patients who have difficulty in viewing.

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

Cataract surgery can be performed to any individual who is suffering from difficulties to see with both the eyes. In most of these instances, the patients are recommended to consider monovision. This process involves inserting the intraocular lens in one eye providing near vision while the intraocular lens in the other eye offer a distant vision. Some people face tremendous difficulties in seeing objects in the night. It is imperative to perform the cataract surgery in all these cases since the growth of cataract can lead to loss of vision as well.

Who is not eligible for the treatment?

Even though you may have a cataract, it is not always necessary to undergo the cataract surgery. You may not notice any changes in your vision even though the cataract may have started to develop. Some people with this condition are absolutely fine with their prescription glasses or using magnifying glasses or using bright lights for reading. Also, people with high blood pressure and diabetes are not considered an ideal candidate for the treatment.

Are there any side effects?

Cataract surgery is among the safest surgical interventions in the history of medical science. Also, it can rarely lead to any kind of side effects. A significantly low percentage of patients experience occurrences like bleeding from the eyes, drooping eyelid, build-up of fluid within the eye, swelling, eye infection, detachment of the retina, feeling of pressure under or within the eye and loosening of the implanted lens. If you feel any discomfort following your cataract surgery, it must be reported to the doctor with no further delay. Also, you must ensure following the guidelines of your doctor to ensure that you experience no unwanted side effects.

What are the post-treatment guidelines?

There is no reason to worry about your eyes feel sore for a few days of completion of the cataract surgery. You may find that there is fluid discharge from your eyes and it has become impossible to see anything in the bright light. Your eye surgeon would prescribe eye drops which would prevent infection, and you must take this for 2 to 3 weeks post operation. You should not drive for at least 2 weeks, pick up heavy objects or do anything that would exert pressure on your eyes. Your doctor may also advise you to sleep in an eye shield for protecting the operated surgery and allow it to heal.

How long does it take to recover?

Healing after the cataract surgery generally doesn’t take much time if you can follow the guidelines suggested by your eye surgeon. It would take about 2 months for your eyes to heal completely with proper medications and application of the eye drops.

What is the price of the treatment in India?

Cataract surgery is one of the most affordable treatment options all over the world. In India, the cost of cataract surgery can range from Rs. 20,000 to Rs. 60,000 depending on the methods and equipment used. Your eye surgeon would be able to guide you better about the cost you are likely to incur for the cataract surgery.

Are the results of the treatment permanent?

In about 90 percent of the cases, the cataract surgery is successful with no infections and complications. Regardless of whether you choose to undergo manual or laser-assisted surgery, the cataract surgery can improve the vision to a considerable extent. But it is important to have realistic expectations as you may have to wear glasses or lens for excellent vision after the surgery.

What are the alternatives to the treatment?

The most common alternative to cataract surgery is wearing lens and glasses that can help an affected individual to see almost clearly. There are also eye drops available which can assist in dissolving the clumped proteins causing cataracts in the eyes. People who cannot undergo a cataract surgery due to health reasons should consider getting the eye drops containing lanosterol as an effective treatment. But it is crucial to consult with an eye surgeon before deciding.

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.

When Should You Opt For A Cataract Surgery?

When Should You Opt For A Cataract Surgery?
All You Need to Know 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: 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. Secondary Cataract: It can be developed after surgery for other eye problems like glaucoma and other health conditions such as diabetes. Traumatic Cataract: It can develop many years later after an injury caused to your eye. 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. 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 lens 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.

Post Cataract Surgery - Tips For It!
A simple, uncomplicated cataract surgery should not take much time to perform. The best part about a cataract surgery is that most people see almost immediate results and improved vision. However, full recovery can take awhile. Each person heals at a different speed but ideally, your eyes should heal completely in a month. Here are a few tips to help speed up this process and avoid infections and eye injuries: Take it easy: Just because the surgery takes a short time is no reason to underestimate its importance. Do not drive on the first day and as far as possible avoid driving for the next few days as well. Do not put any extra pressure on your eyes by bending, lifting weights etc. Try to avoid excessive sneezing and coughing. One should go for regular follow up as advised by your doctor. Use post op medication for a duration as advised by your treating surgeon. Do not use post op medications on your own whenever you have problem. Protect your eyes: Wearing sunglasses is a good idea after a cataract surgery. This will protect your delicate eyes against dust, wind etc. Avoid using community swimming pools and hot tubs immediately after such a surgery to lower the risk of infections. Avoid rubbing your eyes aggressively. For the first week, keep your face out of the shower so as to avoid feeling the need to press or rub your eyes as well as to protect them from bacteria in the water. Lubricate: Your eyes may feel dry and scratchy after a cataract surgery. This is normal and not something to worry about. Your doctor will prescribe eye drops to be taken after the surgery. Use these regularly. Once this is over you may need additional artificial tears or lubricating eye drops. However, do not take these drops without first consulting your doctor. If your eyes are sensitive to the preservatives in bottled eye drops, look for single use ampoules. Ensure that you always wash your hands well before administering the eye drops. Keep the eye clean: Though washing your face is avoidable, you must still keep the eye clean. Use cotton and a sterile saline wash for the first few days. You can later replace the saline with cool boiled water. You should rush to the Ophthalmologist if you develop any sudden onset of pain, watering, redness or blurry vision in the operated eye . Seeing sudden flashes of light or floaters in your vision should also not be ignored. A simple, uncomplicated cataract surgery should not take much time to perform. The best part about a cataract surgery is that most people see almost immediate results and improved vision. However, full recovery can take awhile. Each person heals at a different speed but ideally, your eyes should heal completely in a month.

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: Blurred vision Nearsightedness Changes in the perception of colour Night blindness Increased sensitivity to glares 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 cataracts, 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: Pain and redness of the eye Vision problems Swelling of the eye Discharge from the eye Flashes or floaters in the patient s vision

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: Can you see to safely do your job and to drive? Do you have problems reading or watching television? Is it difficult to cook, shop, do hardwork, climb stairs or take medications? Do vision problems affect your level of independence? 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: Inflammation Infection Bleeding Swelling Drooping eyelid Dislocation of artificial lens Retinal detachment Glaucoma 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.

it is possible for infants to wear glasses using head bands.. in fact glasses will be important so that complete visual developement and teaming between 2 eyes can take place. It was good you were able to detect and surgically treat cataract in time.. but u still need to continue with treatment to ensure the best visual outcomes for your baby. your treating doctor will advice u on what power of glasses are to be used and how they should be maintained. just be sure to follow those instructions.
