The procedure relies on three primary functions, often controlled by a three-position foot pedal:

The technique was pioneered by in 1967, inspired by the high-frequency vibrations of a dentist’s ultrasonic cleaning tool. Before phacoemulsification, cataract removal required a large incision and weeks of recovery. Kelman’s innovation allowed for a tiny incision (typically 2.2–3.0 mm) that often requires no sutures, leading to faster healing and reduced risk of infection. Core Principles of the Procedure Phacoemulsification. / Volume I

Phacoemulsification, often referred to as "phaco," is the modern gold standard for cataract surgery. It is a minimally invasive procedure that uses ultrasonic energy to break up (emulsify) the eye's cloudy natural lens so it can be aspirated and replaced with an artificial intraocular lens (IOL). This transformation from a complex, high-risk surgery to a routine, highly successful outpatient procedure is one of the greatest achievements in modern ophthalmology.
