cataract treatment

Surgical treatment has progressed over the past 20 years so that today, cataract surgery is extremely successful. The modern technique for removing a cataract include the use of a microscopic incision and an ultrasonic probe which is used to break the cataract into minute pieces which are then easily removed from the eye. This method of removing a cataracts is called "phacoemulsification". Cataracts cannot be removed from the eye with laser.

Following removal of the lens, a small plastic intraocular lens is placed in the eye to replace the focusing power provided by the human lens. This lens, or implant, is permanently affixed inside the eye, cannot be felt, and eliminates the need for thick cataract glasses after surgery. Please consult with Dr. Zadeh for more details.
