Cataract causes painless blurring vision. Some cataracts may cause glare or haloes. Night driving may become difficult. Frequent eyeglass prescription changes may indicate cataract. Occasionally, double vision in one eye may be due to cataract. These symptoms can be present in other eye problems also, so you need to check with your eye specialist to confirm.

Cataract is detected through a comprehensive eye examination by an ophthalmologist, which includes a check for glasses, detailed evaluation of the eye including the cataract, retina, optic nerve to rule out any other problems which may cause vision loss

Cataract surgery should be considered when a cataract causes enough vision loss to interfere with daily activities such as driving, reading or watching television.

The main technique used to remove a cataract is phacoemulsification. In phacoemulsification, through a small opening 1.8mm -3mm in size in the cornea, an ultrasonic device is used tois break upthe cloudy lens into small pieces and removed from the eye. After the cataract lens is entirely removed, the lens implant is inserted to the same position.Anaesthetic eye drops / injections are used to make the surgery pain free. Advantages of the recent techniques, as in micro incision cataract surgery are- no injections, no bandage and immediate visual rehabilitation.
