Cataract Surgery

Cataract Surgery is the third most performed surgery in the United States, with over 1.5 million surgeries per year. This surgery also has a very high success rate, with 9 out of 10 people regaining vision between 20/20 and 20/40.

The surgery begins with the doctor making a small incision into the cornea. Next, the surgeon may remove the lens as one piece or use an ultrasound, laser or surgical solution to break the lens into pieces and remove it. The posterior capsule, the membrane at the back of the lens, is left in place so that an intraocular lens can be inserted.

Occasionally the entire lens, including the membrane, will be removed to ensure that the membrane won’t become cloudy over time and interfere with vision. However, if the membrane is removed, a replacement lens cannot be inserted. In this case, corrective lenses must be worn to restore vision.
