Phacoemulsification cataract surgery is a procedure in which an ultrasonic device is used to break up and then remove a cloudy lens, or cataract, from the eye to improve vision. The insertion of an intraocular lens (IOL) usually immediately follows phacoemulsification.

This provides a very detailed, step-by-step animation of how cataract surgery is performed. It also show how an intraocular lens or IOL is inserted after the natural lens is removed in the cataract surgery shown.

In a phacoemulsification procedure, an incision is first made in the cornea, the outer covering of the eye (A). A phacoemulsification instrument uses ultrasonic waves to break up the cataract (B). Pieces of the cataract are then suctioned out (C). To repair the patient's vision, a folded intraocular lens is pushed through the same incision (D) and opened in place (E).

Other Information
Phacoemulsification refers to modern cataract surgery in which the eye's internal lens is emulsified with an ultrasonic handpiece, and aspirated from the eye. Aspirated fluids are replaced with irrigation of balanced salt solution, thus maintaining the anterior chamber, as well as cooling the handpiece.
Other Information
Approximately 56% of all patients achieve results of 20/20 or better and over 90% achieve 20/40 or better (which is good enough to drive without corrective lenses in most regions).1 Those with moderate to high myopia (greater than 7 diopters) have a lesser chance of achieving that result. As technique and technology improve, the results continue to improve.
