The main complaint of a person with cataracts is blurred vision. In early cataracts, the blurred vision is often described as worse under strong sunlight or when the light is bright or when reading. Glare is another common complaint, especially when driving at night. As the cataract matures, the vision gets more and more blurred and colours appear less strong.
In some early cataracts, vision may be improved slightly with corrective lenses. As the cataract matures, frequent changes of glasses are necessary and at some point, lenses will not help anymore.
Treatment for Cataract
The only treatment available for a cataract that is causing poor vision is to remove it by surgery and place it with an artificial
lens implant made of acrylic or silicone. There are no eye drops, pills or diets that are of proven value in curing cataracts. Laser too cannot be used to remove cataracts.
The good news about cataracts is that good vision can be restored in well over 95 per cent of cases. Most cases of poor vision after cataract surgery are in fact due to eye diseases such as glaucoma and retinal diseases which exist even before surgery.
When to go for Cataract Surgery?
The time to go for cataract surgery is when the cataract handicaps vision enough to interfere with your normal daily activities. It is not necessary to remove a cataract jus because it is there, unless it is very mature, in which case there is risk of complications such as iritis or glaucoma developing. Vision will of course be very poor.
Some time ago, patients were advised to wait until a cataract became mature or ‘ripe’ before removing it. However, with today’s advances in surgical techniques, safe removal of cataract is possible even at a very early stage.
Usually only one eye (the eye with the worse vision) is operated on first. Once healing is complete in that eye and good vision restored, a decision can be made regarding surgery for the other eye.
