Cataract surgery is necessary when a patient’s vision has started to become affected by cataract(s). A cataract is the gradual clouding of the crystalline lens inside the eye. Cataract Surgery involves the removal of the cloudy cataractous lens, and replacing it with an artificial intraocular lens. If both eyes are affected, they are usually operated a few weeks apart.

Intravitreal injection of a drug into the eye is a very common and effective treatment option for a number of eye conditions, including wet age-related macular degeneration, retinal vein occlusions and diabetic maculopathy. They are very effective for treating these conditions, particularly when the problem is caught early. They are also very effective at preventing further vision loss. Vision is known to improve in a significant proportion of patients.
