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 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.

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.
- 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.
If you are diabetic then it is important that you visit your ophthalmologist for regular check-ups. Diabetes is known to be one of main causes for blindness across all age groups. If you suffer from bouts of blurred vision then it is not likely due to a long term vision problem. It is temporary and usually occurs due to fluctuating blood sugar levels in the body.
How diabetes affects your eyes?
The lens of your eyes can swell if you are a diabetic, and this can impair your ability to see causing blurry vision. In order to rectify this problem, it is important for you to get your blood sugar levels under optimal levels. This entire procedure of reducing blood sugar levels may take three months or more.
Eye problems that are caused by diabetes-
The major eye problems that can occur due to diabetes are-
- Cataract: Cataract occurs when the lens of your eyes become foggy or cloudy. Although cataract mostly occurs to people who are middle aged or above sixty, you can get affected by this disorder at an earlier age if you are diabetic. Also, the deterioration or clouding of the lens progresses at a much faster rate than usual. Cataracts lead to an inability to focus as the retina is covered by cloudy layer.
- Glaucoma: This is another disorder that can occur due to diabetes. This is characterized by the buildup of pressure in the eye due to the fluids within it not draining properly. This intense pressure damages the nerves and blood vessels in the eyes, thus impairing your ability to see.
- Diabetic Retinopathy: Diabetic retinopathy is a disorder characterized by damage to the vessels in the retina that carry blood. It can occur if you have either of the type 2 or type 1 diabetes. If not treated in time it can lead to blindness.
If you have a history of diabetes or even borderline diabetic tendencies, it is highly advisable to constantly check your blood sugar levels and also get your eye checked at regular intervals, especially if you feel even the minutest vision problems.
My eyes is suffering from squint and my eye bal keep shaking. Can this be treated? How long and what is the price for surgery?
I am a patient of primary sjogren's symptoms since 2012. Now I have problem in eyes and mouth since 2012 and I have problem in legs joint in walking .what to done to cured from this doses.
The eyes are such a complex structure that even minute changes in the extremely complicated internal structure affects the most important function of the eye, vision. And anyone with a vision problem can vouch for the extent of effect it has on the quality of life. Whether you are able to see only things at a close distance or far off, it is definitely difficult.
The good news, however, is that with the thorough understanding of the eye’s structure, these abnormalities can be corrected and absolutely normal vision can be restored. While surgery was the only mode of correction a few decades ago, but laser has come to rescue, especially in intricate structures like the eye.
LASIK is an abbreviation for laser in-situ keratomileusis. This is the most common and popular method to correct vision in errors of refraction. In all these conditions (as below), the cornea which is the clear portion in the front of the eye is affected.
The light passes through the cornea, lens and falls on the back of the eye ( retina), where an image is created, sent to the brain where it is reversed, and this is what we ‘see.’ Each of these parts have to be in perfect condition in order to produce this proper sight. Errors of refraction fall into three main categories.
- Nearsightedness: There is difficulty in seeing far off objects, so road signs and boards are difficult to follow. Seeing objects that are closer is not affected. Most important cause is excessive staring into computer monitors.
- Farsightedness: The person has difficulty seeing things that are nearby and has to hold them at a distance for clarity.
- Astigmatism: Light rays merge to focus on multiple points either in front of or behind the retina. Normally, however, they should focus on a single point on the retina. There could be blurred vision, squinting, and eye strain.
What is done?
During the laser surgical procedure, ultraviolet laser beam is directed at the cornea. It is reshaped - made thinner in nearsightedness, elongated in farsightedness, and restoring the normal shape in astigmatism. This ensures that light is focused properly on the retina, producing sharp images and restoring vision.
