Selig Percy Amoils, born in 1933, is a South African ophthalmologist and biomedical engineering inventor. In 1965 he refined the cryoextraction method of cataract surgery by developing a cryoprobe cooled through the Joule-Thomson effect of gas expansion, a system still widely used in ophthalmology and gynaecology. He also received a patent for a rotary epithelial scrubber, an improvement on a brush first developed by Ioannis Pallikaris for removing corneal epithelial cells before photorefractive keratectomy. Other work attributed to him includes a diamond vitrectomy cutter developed in 1970, instruments giving micro-control of blade depth in radial keratotomy, and an oval comparator or astigmometer to control astigmatism after cataract surgery.
