Deshpande YR 1975 UL http://bjo.bmj.com/content/59/3/171.abstract AB The general belief that the technique of cataract extraction in India in the Sushruta period (800 B.C.) was couching is no longer tenable. A study of the original text suggests that the method was more closely allied to the extracapsular extraction of recent times.
