What did Harold Ridley and intraocular lens black plaque do at St Thomas' Hospital?

The Story

# St Thomas' Hospital, Lambeth Standing before St Thomas' Hospital on the Thames' south bank, you're looking at the birthplace of modern cataract surgery—the precise spot where, on a winter morning in 1950, Mr. Harold Ridley FRS performed an operation that would transform the lives of millions. The procedure itself was audacious: instead of simply removing a clouded lens and leaving patients nearly blind without glasses, Ridley implanted the world's first intraocular lens, a piece of clear acrylic that would restore sight by mimicking the eye's natural function. This wasn't theoretical medicine conducted in a laboratory; it happened here, in these very operating theatres where Ridley worked as an ophthalmologist, where he had spent years observing how shards of acrylic from aircraft cockpits had lodged harmlessly in airmen's eyes during World War II, sparking his revolutionary insight. That single 8th February morning at St Thomas' marked the moment when blindness became optional, when cataract—one of humanity's oldest afflictions—stopped being a sentence to darkness, making this Georgian riverside building hallowed ground in the history of sight itself.
