Cataract surgery is performed by an ophthalmologist, according to Medline Plus. The patient is awake for the procedure. A numbing solution is given using eyedrops or an injection to block pain and help the patient to relax. The ophthalmologist will use a special microscope to look into the eye.

An incision is made in the eye, and the clouded lens is then removed, says Medline Plus. The lens can be removed using phacoemulsion. In this procedure, the ophthalmologist uses sound waves to break up the lens and then uses suction to remove the lens pieces. Another method of removing the lens is by removing the whole lens through a larger incision. A third method is using laser to soften the lens for removal by suctioning.

After the clouded lens is removed, an artificial lens is put in place. The ophthalmologist then stitches up the incision. The whole procedure lasts for less than half an hour, according to Medline Plus. After the cataract procedure, the patient needs to wear a patch over the eye and put eyedrops into the eye to prevent infection. On the day after the procedure the ophthalmologist will review the eye.
