Phacoemulsification, or phaco, is method of cataract surgery in which the eye’s internal lens is emulsified using ultrasonic energy and replaced with an intraocular lens implant, or IOL. How is it done? Phaco surgery is performed with a small ultrasonic probe that is inserted into the eye via a two-to-three millimeter incision. This probe breaks the cloudy lens into tiny pieces and sucks the fragments out of the eye. Your doctor will place a permanent artificial lens (called an intraocular lens or IOL) where the natural lens used to be.
