Are there different options for incisions with cataract surgery? In 2012 the FDA approved the first laser designed to be used during cataract surgery. Laser cataract surgery makes very precise incisions in the cornea using laser technology. The laser then makes a perfectly circular opening on the lens surface. The same small ultrasound probe used in regular cataract surgery is then used to liquefy and remove the cloudy cataract lens. Astigmatism treatments can also be performed with a laser (limbal relaxing incisions).
