A cataract occurs when the eye’s natural lens becomes cloudy. During traditional cataract surgery, cataract surgeons use a small blade to enter the front of the eye and another instrument to make a circular incision on the lens capsule to reach the cataract. Ultrasound waves break the cataract into tiny pieces, which are then removed. The new artificial lens is inserted to replace the cloudy natural lens.
In laser cataract surgery, a laser is used to make the incision and lens opening, explained Dr. Horne. “It creates a more reliable, repeatable, precise incision than a surgeon can do by hand. Even a very good surgeon can’t make a perfect circle as precisely as a laser can.”
