The earliest documented references to cataract surgery are found in Sanskrit medical manuscripts dating to the 5th century BC. These texts describe the work of Sushruta, an ancient Indian physician who developed specialized surgical instruments and performed some of the earliest known eye surgeries, including extracapsular techniques for cataract treatment.[1][2] The Susrutasamhita describes removal of cataracts using sharply pointed instruments, representing some of the first recorded ophthalmic surgical procedures.
In the Western world, bronze instruments that may have been used for cataract surgery have been identified in archaeological excavations in Babylonia, Greece, and Egypt. Although cataracts are not explicitly described in surviving ancient Egyptian medical texts, a condition resembling cataract has been referenced in the Ebers Papyrus. The earliest detailed Western medical descriptions of cataract and its treatment appear in De Medicina (circa 29 AD), written by the Roman encyclopedist Aulus Cornelius Celsus, who described couching as a surgical intervention for cataract.
Couching involved using a thin needle or similar instrument to displace the opaque lens posteriorly into the vitreous cavity. Although this technique occasionally restored limited light perception, it was associated with poor visual outcomes and high complication rates. Nevertheless, couching persisted from antiquity through the Middle Ages and remained the dominant method of cataract treatment for centuries.
In ancient Greek medicine, the crystalline lens was believed to be the structure responsible for vision. This belief contributed to the development of the emanation theory of vision, which proposed that visual “spirits” traveled from the brain through hollow optic nerves to interact with rays from the external world at the lens. Around 30 AD, Celsus depicted the lens at the center of the globe with an anterior empty space known as the locus vacuus. This anatomical model persisted through the Middle Ages and into the Renaissance, as illustrated by the Belgian anatomist Andreas Vesalius in 1543.
The first accurate depiction of the crystalline lens position was published by the Italian anatomist Fabricius ab Aquapendente in 1600. Swiss physician Felix Plater later challenged prevailing theories of vision by proposing that the retina, rather than the lens, was the structure responsible for sight.
A major transition in cataract treatment occurred in 1748 when Jacques Daviel introduced true cataract extraction, in which the opaque lens was removed from the eye rather than displaced. This marked the beginning of modern cataract surgery. Further advances occurred in the 20th century, including the introduction of intraocular lens implantation by Harold Ridley in the 1940s, which significantly improved postoperative visual rehabilitation (Apple et al., 2000).
Modern cataract surgery continued to evolve with the introduction of phacoemulsification by Charles Kelman in 1967. This technique uses ultrasonic energy to emulsify the lens nucleus, allowing cataract removal through a small incision and reducing the need for prolonged hospitalization. These innovations established extracapsular cataract extraction and phacoemulsification with intraocular lens implantation as the foundation of contemporary cataract surgery (Apple et al., 2000).
By the late 20th and early 21st centuries, cataract surgery had become one of the most commonly performed surgical procedures worldwide. Surveys of members of the American Society of Cataract and Refractive Surgery reported approximately 2.85 million cataract procedures performed in the United States in 2004 and 2.79 million in 2005.[3] In India, modern cataract surgery with intraocular lens implantation has largely replaced older techniques, particularly through government and non-governmental organization–sponsored eye surgical camps.
