Cataracts and Cataract Surgery

When a person has a cataract, the normally clear lens of the eye is clouded, making vision appear as though they are looking through a foggy window. Although slow to develop, this can make it difficult to complete normal, everyday tasks, such as seeing someone’s facial expressions, reading, or driving a vehicle.

Once the cataracts worsen, cataract surgery may be necessary to correct the problem. This is where top cataract surgeons come into play.

A cataract surgery is a procedure that removes the clouded lens of the eye and replaces it with an artificial lens. This surgery is typically a safe, effective treatment for progressed cataracts.
