This article underscores the monumental contributions of Sir Harold Ridley to the development of intraocular lenses (IOLs), which have revolutionized cataract surgery. Sir Harold Ridley, a British ophthalmologist and medical scientist, drew inspiration from the injuries of World War II pilots to pioneer the first successful IOL implantation in 1949 at St. Thomas's Hospital. The lens, made from Perspex CQ, marked the inception of modern cataract surgery. Despite facing considerable skepticism and resistance from the medical community throughout the 1950s and 60s, Ridley's perseverance led to the gradual acceptance of IOLs by the 1970s. Today, Ridley is rightfully recognized as the "father of the intraocular lens," with his groundbreaking work having profoundly impacted the field of ophthalmology and improved the quality of life for millions globally.
