The goal of glaucoma treatment is to decrease the pressure in the eyes. This is achieved using special eye-drops or medications. Surgery is recommended if medications don’t yield the desired result, or with an aim to prevent further vision loss or blindness.
Surgery is the only treatment for cataract and is recommended based on the severity of the condition and the impact it has on the daily activities of the patient. It is performed one eye at a time with a few weeks gap in between the two operations.
When light enters the eye, it is focused on a photosensitive retina to provide clear vision. Abnormalities in the cornea (transparent outer layer of the eye), such as excessive curvature (near-sightedness) or dryness, causes light to focus before or after the retina, resulting in blurred vision.
