Retinal Cryoprobe

At the Baragwanath Hospital in Soweto, Dr. Selig Percy Amolis introduced his masterwork, the retinal cryoprobe. Used to reattach retinas and for advanced cataract surgery, the model soon became widely used, and Amolis received the 1975 Queen’s Award for Technological Innovation. Margaret Thatcher’s cataracts were treated with the cryoprobe, as were Nelson Mandela’s eyes the day after he became president.
