When Dr. Ruit returned to Nepal he was instrumental in the formation of the Nepal Eye Program and worked on a large epidemiological survey of blindness in Nepal. [citation needed] He was the first Nepali doctor to perform cataract surgery with intraocular lens implants and pioneered the use of microsurgical extra-capsular cataract extraction with posterior chamber lens implants in remote eye camps. [citation needed] Although other important international organizations sponsored eye camps in the region providing eye care and training local ophthalmologists, the camps established by Dr. Ruit were the first to introduce the use of intraocular lenses in cataract surgery. Put simply, this is the removal of the cataract and insertion of a plastic intraocular lens.[1]
