This method of surgery reduced the need for an extended hospital stay and made out-patient surgery the standard. Patients who undergo cataract surgery rarely complain of pain or discomfort during the procedure, although those who have topical anaesthesia, rather than peribulbar block anaesthesia, may experience some discomfort.

Cataract surgery in small animals such as dogs and cats is a routine ophthalmic procedure with a success rate of around 90%, and is usually better for eyes with relatively recent cataract development. The presence of other ocular problems may reduce the success rate. Procedures are similar to those for humans.
The intraocular lens did not find widespread acceptance in cataract surgery until the 1970s, when further developments in lens design and surgical techniques had come about. As of 2021, approximately four million cataract procedures take place annually in the U.S. and nearly 28 million worldwide, a large proportion in India.
Kwitko was the first doctor in Canada to insert intraocular lens implants during cataract surgery (1967) [1] and the first doctor in Canada to perform radial keratotomy surgery (1979). [3] He was associate professor of ophthalmology at McGill University in Montreal as well as Chief of Ophthalmology at St. Mary’s Hospital in Montreal. [4]
In the 1970s he developed the surgical technique he is most famous for, the radial keratotomy, to change the shape of the cornea and cure myopia. [2] In 1986, Fyodorov designed the first posterior chamber phakic IOL in the "collar-button" or "mushroom" configuration and manufactured the pIOL from silicone. In 1980 he became the head of the ...
Announced on 31 December 1999, the New Year Honours 2000 list for the United Kingdom and New Zealand included Ridley as one of forty-five people accorded with the honour of Knight Bachelor, "for pioneering services to Cataract Surgery". [18] Subsequently, at a ceremony in February 2000, aged 93, he was knighted by the Queen at Buckingham Palace.
Manual small incision cataract surgery (MSICS) is an evolution of extracapsular cataract extraction (ECCE); the lens is removed from the eye through a self-sealing scleral tunnel wound. A well-constructed scleral tunnel is held closed by internal pressure, is watertight, and does not require suturing.
Until the acceptability of the keratome-and-scissors method after the early 1940s, an essential part of cataract surgery was mastery of the von Graefe knife. With increased popularity of sutures—especially pre-placed scleral groove (McLean) sutures, it became difficult for the occasional surgeon to develop the skill required to make an acceptable von Graefe incision.
