Charles David Kelman (May 23, 1930 – June 1, 2004) was an American ophthalmologist, surgeon, inventor, jazz musician, entertainer, and Broadway producer. Known as the father of phacoemulsification, he developed many of the medical devices, instruments, implant lenses and techniques used in cataract surgery. In the early 1960s, he began the use of cryosurgery to remove cataracts and repair retinal detachments. Cryosurgery for cataracts remained in heavy use until 1978, when phacoemulsification, a procedure Kelman also developed in 1967, became the modern standard treatment. Kelman was given the National Medal of Technology by President George H. W. Bush and recognized as the Ophthalmologist of the Century by the International Congress of Cataract and Refractive Surgery in Montreal, Canada.
