The Falkland Islands Government Health and Social Services Department provides medical care for the islands. The King Edward VII Memorial Hospital (KEMH) is Stanley's only hospital. It was partially military operated in the past but is now under complete civilian control. There are no ophthalmologists or opticians on the islands, although an optician from the United Kingdom visits about every six months and an ophthalmologist comes to do cataract surgery and eye examinations on irregular intervals (once every few years). There are two dentists on the islands.
