Гарольд Ридли: Көз ілмегін құтқарушы және соғыс жылдарының оқиғалары

English ophthalmologist

Nicholas Harold Lloyd Ridley was born in Kibworth Harcourt, Leicestershire, the elder son of Nicholas Charles Ridley and his wife, Margaret (née Parker). He had a younger brother. Known from childhood by his middle name (Harold), Ridley had a stammer which he was largely able to manage. As a child he met and sat on the lap of Florence Nightingale, a close friend of his mother. The intraocular lens was approved as "safe and effective" and approved for use in the USA by the Food and Drug Administration in 1981. The first FDA approved lenses – Choyce Mark VIII and Choyce Mark IX Anterior Chamber – were manufactured by Rayner. In 1987, Gordon "Mouse" Cleaver, whose injury in 1940 helped Ridley conceive the idea of using an acrylic intraocular lens, underwent cataract surgery and the implantation of such a lens to restore his sight.

Ridley was in civilian hospital services in South East England during the early years of World War II, when he saw injured pilots from the Battle of Britain. In the middle to end years of the war he was with the R. A. M. C (Royal Army Medical Corps) and was posted to West Africa and South East Asia.

Writing as Major Harold Ridley, he published in 1944 a short paper in the British Journal of Ophthalmology on spitting snakes and an account on the composition and action of snake venom in general. From his own experiences in the Gold Coast, Ridley described snake venom ophthalmia in a 30 year old labourer named Gogi Kumasi who was cutting grass when a Black necked cobra raised its head from the grass and forcibly spat venom toward the man's right eye from a distance of four or five feet. Ridley treated the man and followed his case until the eye had fully recovered, after about a week. After discussion on the therapeutic uses of snake venom, he conjectured that in the future diluted venom or a constituent of venom might be used as a powerful anaesthetic in some cases of ophthalmic surgery.

After completing 18 months in Ghana, in 1944 Ridley was transferred to India and then Burma, where he studied and treated malnourished former prisoners of war. His biographer David Apple reports Ridley's own words: "In Calcutta, we basically had nothing to do with no assignments – a situation which continued after transfer to Parragan, near Calcutta. Finally, I was transferred to Rangoon, Burma, where life began again. I treated over 200 released allied prisoners of war in Rangoon and Singapore who suffered from nutritional amblyopia while Japanese prisoners of war. Many of the prisoners had worked on the Burma Railway. Starved and ill treated, they had developed sudden central scotoma, relieved by good diet if available. Some developed optic atrophy, some of whom made a partial recovery within six weeks of release. However, the advanced cases, though given a vitamin rich diet were irreversible. I subsequently wrote an article on the topic of nutritional amblyopia." His paper was published in 1945. "It is uncertain whether disturbance in a visual pathway originates in the retina or optic nerve. Failure of the cortical capillaris to nourish the outer retinal layers at the macula may be significant." The therapy he used anticipated the use today of multivitamins in ARMD patients. Ridley used multivitamin therapy, returned them to a normal diet, and then noted improvement in the prisoners' condition. The Burma theatre of war permitted the first large population study of individuals with nutritional amblyopia: a total of over 500 within his region of whom about 200 he personally examined and treated. At that time there was widespread opposition in the profession to the use of IOLs. to raise funds for cataract surgery in developing countries and to treat avoidable blindness. the organisation continues to be active in these fields today, notably in the Middle East. Ridley's son Nicholas serves as its chairman.

Ridley retired from NHS hospital service in 1971. Subsequently, at a ceremony in February 2000, aged 93, he was knighted by the Queen at Buckingham Palace. This Millennium Honour was the culmination of years of lobbying work by Ridley's biographer (David J Apple) and prominent surgeon friends such as Emanuel Rosen and Thomas Neuhann, together with leaders of the ophthalmic medical device industry such as Donald J Munro, chairman and managing director of the Rayner company of Brighton & Hove, UK. A Heritage blue plaque to commemorate his groundbreaking work was installed in Kibworth Harcourt, Leicestershire on 18 February 2012, thanks to the research carried out by Bob Haggerty, a local resident who has himself had an intraocular lens fitted, and supported by Kibworth Improvement Team (KiT), the local community partnership. A plaque in memory of Ridley is installed in the gardens of his alma mater Pembroke College, Cambridge, which plaque reads: "RIDLEY’S WALK / This plaque is placed in memory of Sir Harold Ridley FRS 1906 2001 / pioneer of intraocular lens surgery, graduate & benefactor of this College / after whose ancestor Bishop Nicholas Ridley, Master 1540 1553, / martyred 1555, this path is traditionally named". In 2013, a biographical profile of Ridley was included in a book called Saving Sight: An eye surgeon's look at life behind the mask and the heroes who changed the way we see, by Andrew Lam.

On 6 January 2016, during the BBC 1 television programme The One Show a short film was shown about the link between Gordon Cleaver and Harold Ridley. Using archive film and photographic material and an interview with Sir Harold's son, Nicholas, Michael Mosley reported on the "Eureka moment" that led to the invention of the intraocular lens. The film was made by ICON Films of Bristol.
