Two methods cataract extraction are:
Intracapsular: involves a large incision. The lens is picked up for extraction with forceps, suction, or a cryoprobe. The ENTIRE capsule is removed.
Extracapsular: performed through a small incision and the lens is expressed or removed manually or by phacoemulsification. The phacoemulsification method uses ultrasonic energy to break up the lens: the lens material is irrigated and aspirated simultaneously. The posterior capsule remains. During this surgery, a superior rectus bridal suture is placed for manipulation and stabilization of the globe. An incision is made, either corneoscleral or corneal, which is self-sealing.
