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.
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 nearsightednessor 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.

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?
Complications after cataract surgery are uncommon, and most can be treated successfully.
Cataract surgery risks include:
- Drooping eyelid
- Dislocation of artificial lens
- Retinal detachment
- 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 can be defined as the clouding of the natural lenses in the eyes. This is caused by the clumping of protein in the eye lens. Cataract is a common eye disorder and the leading cause of loss of vision in people who are past their fortieth birthday. Cataract can occur in one or both eyes. When diagnosed properly, cataract can be treated with surgery to prevent blindness.
Depending on where and how they develop, there are many types of cataract. The most common amongst these are:
1. Subcapsular cataract
These occur at the back of the eye lens. Diabetic patients are very susceptible to this kind of cataract.
2. Nuclear cataract
A yellowish-brown cataract that forms in the center of the lens is called nuclear cataract. This is usually seen in cataract caused by ageing.
3. Cortical cataract
Cataract in the lens cortex is known as cortical cataract. These are wedge-shaped and whitish in color. Spokes protruding out of these opaque wedges can be seen moving towards the center of the eye.
4. Congenital cataract
Though they are not common, babies can also have a cataract. Cataract formed at birth or within the first year of a baby's birth is known as congenital cataract.
5. Secondary cataract
6. Traumatic cataract
If your vision becomes cloudy years after an eye injury, it could be a traumatic cataract. It can take several years for this to happen.
7. Radiation cataract
2.Reduced night vision
3.Increased sensitivity to light and glare
4.Seeing halos around lights
5.Colors appearing faded
A reading test is the first step towards diagnosing cataracts. This is followed by tests to measure eye pressure. Your doctor will also need to dilate the pupil to check the condition of the optic nerves and retina.
Surgery is the safest way to remove a cataract. Surgery is usually recommended when cataract begin inhibiting your daily life such as preventing you from driving, interfering with reading etc.
In most cases, this can be done as an outpatient procedure. The earlier it is diagnosed, the easier it is to treat. Hence, if you notice any of the symptoms mentioned above, get your eyes checked at once. The surgery is a day-care surgery only, so a person can go home the same day.
The surgical procedure to correct the appearance of eyelids is called blepharoplasty. The correction is done by removing extra skin, fat and muscle that make the eyelids droop.
Eyelids start drooping when the muscles supporting your eyelids weaken as you grow older. Excess fat accumulates below and above your eyelids as a result, which leads to eye bags and droopy eyelids.
Besides making you look older than your age, droopy eyelids can also affect your vision. Blepharoplasty can improve your vision and give your eyes a polished look at the same time. Some other benefits include:
Excess deposits of fat that make eyelids look puffy are removed with the help of blepharoplasty.
Eye bags are reduced.
Drooping eyelids which end up revealing the sclera (the white part in your eyeballs) are fixed.
Fine wrinkles and excess skin around lower eyelids are corrected.
Blepharoplasty is usually combined with procedures such as skin resurfacing, face-lift or brow-lift.
Blepharoplasty, like every other surgical procedure, has certain risks, which include—
Irritated, dry eyes
Trouble closing eyes and other associated problems
Eye muscle injury
Follow-up surgery is needed
Short-term blurry vision, or in unusual cases, loss of vision
General risks associated with surgery such as blood clots, anaesthetic reactions, cardiac and other coronary problems.
Before the surgery can be scheduled, a surgeon and ophthalmologist will be consulted to record your medical history and discuss your expectations about the surgery. Then, before the procedure can begin, the following steps will be followed:
First, you will be examined physically; your doctor will test your tear ducts and take measurements of your eyelids.
Second, your eyes will be examined and your vision will be tested.
Lastly, your doctor will take photographs of your eyes which will facilitate and guide him/her through the course of the surgery.
The effects of blepharoplasty are long-lasting and the corrections are permanent. Durable sun protection of the eyes helps in maintaining the corrections made.
Although, you can get excellent results from one surgery, sometimes you may need multiple procedures to achieve the desired look.
If you have got diabetes, then it is quite natural that you will soon face acute eye troubles. This is the reason diabetic patients are always suggested to keep their blood sugar levels controlled so that eye troubles can be easily avoided.
Thorough medical check-up is required in order to detect conditions of the eyes. Some of the commonest eye troubles occurring due to diabetes are cataract, glaucoma, blurry vision, diabetic retinopathy and others.
List of eye diseases caused by diabetes are as below:
- Diabetic retinopathy
When retina's smallest blood-vessels get severely damaged due to increased blood-sugar, then this kind of eye condition occurs. Early detection of this eye condition can save your
eyes, but if it is too late, then nothing can be done, and it might even lead to blindness.
Fogging or clouding condition can bring this kind of condition, and this can only be corrected by wearing proper corrective lenses. However, if you fail to control diabetes, then in spite of wearing glasses, your eye condition might get deteriorated day by day. Glared or blurred vision is the commonest symptom in this regard.
When the eye-fluid is not drained properly, then this kind of eye trouble occurs. In fact, eye pressure increases to a great extent as a result of which delicate eye nerves can get severely damaged. The blood vessels of the eyes can get clogged causing greater interruption in vision. Medicines can make aqueous humor to get drained in a proper manner, and thus you should go for a proper eye check-up so that you can acquire the requisite medicines. Some popular symptoms of glaucoma are headaches, eye aches, blurred vision, watery eyes, vision loss and others.
- Diabetic macular-edema
This eye disease mainly occurs in the advanced stage of diabetic-retinopathy. Macula is nothing but the most delicate part of retina and when it gets swollen, then you might face this eye trouble. Only medications can help you to get rid of the same and thus immediate medical help is needed.
- Blurry vision
Though this is quite a small and temporary eye issue for diabetic patients, but this condition might turn into a serious one if you neglect to correct the same in the very beginning. You might even face blindness due to negligence of this trouble. Also, fluctuating sugar-levels should be stabilized so that this kind of trouble can be easily tackled.
I am experiencing a foreign material in my right eye from last night what to use to clear my eye its very irritating.
Dear sir/mam. I have eye power is RE -0.75 & LE -0.50, Can I use Contact lenses? Since I want to remove my specs permanently.
Glaucoma is a group of diseases that causes damage to your eye's optic nerve and gets worse over time. The optic nerve is a bundle of millions of nerve fibres which carry visual impulse from the retina at the back of eye to the brain. The increased Eye pressure, called intraocular pressure, can damage the optic nerve and fasten the natural nerve fibre loss. Since nerve cells can't regenerate this damage is permanent and irreversible.
I am 68 years old. I have done my Cataract surgery on my right eye. I have some problem with my vision .Would like to consult with you. Thank you very much.
This is a condition which can be caused in the delicate folds of the skin over the eye called the eyelid. The eyelids usually protect us from extreme light, and the entrance of other debris as well as against injuries to the delicate interiors of the eyes. The eyelid may get irritated or experience varied sensations like prickling, burning or itching, with a dull ache or sharp pain due to many reasons. This discomfort and irritation is usually caused by inflammation. Let us learn more about this condition.
Eyelid Inflammation: Blepharitis or eye inflammation is a condition that causes eyelid irritation because of allergic reactions as well as infections, dandruff in the eyelashes and eyebrows, pollutants and varied other causes. Also, poor hygiene can lead to the growth of eyelash lice which can also enter the eyes and lead to inflammation and irritation of the eyelids. A malfunctioning oil gland can also cause this kind of problem along with side effects of certain kinds of medication.
Types of Inflammation: This condition can be of two types :- anterior and posterior. Anterior eye inflammation causes irritation in that part of the eyelids which are outside the eyes where the eyelashes are situated. Dandruff and allergic reactions can also cause this kind of irritation. Posterior eyelid inflammation is a condition that can be found in the inner rims and corners of the eyes where malfunctioning oil glands found in the follicles of the eyelashes can cause this problem leading to blurry or cloudy vision as well.
Symptoms: Apart from irritation and not being able to close the eyes properly, there are many other symptoms of this condition. These symptoms include sensitivity to glares of light, oily eyelids, burning and itching sensation, and a feeling that some particles have entered your eyes and formed a crust on your eyelashes.
Checking for an Infection: Many of these symptoms can point at the presence of an infection, especially when accompanied by fever and headaches. Yet, irritation can also just be a cause of simple inflammation or due to the entry of a foreign body into the eye. Still, it is always best to get the symptoms checked by an ophthalmologist who will conduct a detailed eye exam along with lab tests based on blood samples in order to ensure that there is no bacterium or virus infecting the body.
Treatment: Steroids and antibiotics will be used only when there is an infection. As a home remedy for this condition, you can apply a warm wash cloth and clean your eyes frequently.
Talk to your doctor about potential complications of this irritation like eyelash loss.
