The first record of cataract surgery is from 600 BC in India. They used couching in which the cataract is surgically dislocated from the vertical axis using a surgical instrument. Modern surgery has significantly evolved from couching but it must be understood that couching is still performed by some traditional healers in mainly African and rural China regions. The risks involved in couching are high. A major advance in the cataract surgery was the implantation of an artificial lens within the eye to replace the natural crystalline lens. The procedure is known as cataract extraction. The revolutionary technique of phacoemulsification reduced the morbidity from cataract surgery significantly as it allowed access to the cataract using a much smaller incision as compared to the previously done techniques.
