Cataract extraction is a surgical procedure to remove a lens in the eye that has become cloudy over time, affecting vision in that eye. It is part of a cataract operation, in which the removed lens is replaced with an artificial, manmade lens. The normal lens of the eye is clear and transparent, but the lens and vision become unclear as protein deposits build up on the lens, creating a cataract. Prior to cataract extraction surgery, patients usually are given local anesthesia via eye drops or an injection, and additional medicine often is given to help the patient relax. The eye doctor (ophthalmologist) uses a special microscope to view the eye. A shallow incision is made in the eye, and the lens is removed through the incision. Depending on the type of cataract, the surgeon may use sound waves to break up the cataract into small pieces to be suctioned from the eye through the incision; a tool to remove the cataract in one piece with a larger incision; or a laser to make incisions and soften the cataract before suctioning it. Use of the laser instead of a scalpel may provide a more accurate cut and reduce recovery time. Once the lens is removed, the doctor replaces it with a clear lens called an intraocular lens and then closes the incision. The surgery typically lasts fewer than 30 minutes.
