In 1753, Samuel Sharp performed the first-recorded surgical removal of the entire lens and lens capsule, equivalent to what became known as intracapsular cataract extraction. The lens was removed from the eye through a limbal incision. [1] At the beginning of the 20th century, the standard surgical procedure was intracapsular cataract ...
Couching (ophthalmology) "Couching for cataract"; Wellcome Collection illustration of Indian doctors performing the technique. Couching is the earliest documented form of cataract surgery.

Sir Nicholas Harold Lloyd Ridley [1] [3] (10 July 1906 – 25 May 2001) was an English ophthalmologist who invented the intraocular lens and pioneered intraocular lens surgery for cataract patients.

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.

Manual small incision cataract surgery. 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.
