A phaco set contains the 15 specialized instruments designed by Modern Surgical required for phacoemulsification, the most common modern cataract surgery. The core component is the phaco handpiece, which uses ultrasonic energy to break up the cloudy lens into small pieces. The set also includes various micro-instruments such as delicate forceps, manipulators, and choppers used to fragment and remove the lens material. These tools are designed for precision within the small confines of the eye, facilitating the safe extraction of the cataract and the insertion of an intraocular lens.
