A cataract is a clouding of the normally clear lens of the eye. The lens focuses light rays on the retina at the back of the eye. When a cataract forms, the light rays cannot pass easily through it, and the image becomes blurry. After an eye exam by your physician to diagnose cataract, your physician may recommend cataract surgery. The physician will discuss your options with you and explain the procedures.
Cataract surgery involves making a small incision in the eye.
Microsurgical instruments are used to fragment and suction the cloudy lens from the eye. Once the cataract is removed, a plastic intraocular lens implant will be placed inside the eye to replace the natural lens. The incision is made in such a way that the eye's internal pressure actually seals the incision. This usually results in a faster healing time with fewer restrictions. Local anesthesia is most commonly used, either injections or topical anesthesia.
