Cataract Sx is extremely delicate surgery and is performed under general anesthesia with high-magnification using an operating microscope involves making a small incision is made in the eye and a hole is made in the capsular bag that holds the lens. Phacoemulsification is then performed, in which a special probe ultrasonically emulsifies and removes the cataract (all of the lens contents inside the capsule). After the cloudy lens is removed, the empty lens capsule remains and is called the capsular bag. An artificial replacement lens, called an intraocular lens or IOL, is placed in the bag. The eye is closed with extremely small absorbable sutures. IOLs are either rigid polymer plastic lenses or soft foldable lenses.
