Charles Kelman is widely acknowledged as the leading innovator in the field of ophthalmology. His most celebrated achievement has been the development of the procedure for removing cataracts known as phacoemulsification, as well as the creation of instruments for carrying it out. In 1966, Kelman designed the phacoemulsifier, an instrument that liquefies cataracts within their capsules for extraction. Once the cataract is liquefied with a vibrating ultrasonic tip, the resulting fragments are then suctioned out through a small vibrating needle.

Invention Impact

This pioneering procedure dramatically reduced the risk of complications and turned a one-day hospital stay into an outpatient procedure.
