title: Visual impairment following radial keratotomy. A cluster of cases.
abstract: Thirteen patients who underwent radial keratotomy developed complications leading to visual impairment. Three eyes were legally blind. Two groups of complications were seen: those common to surgical procedures involving the eye--optic atrophy, infections, cataract and retinal detachment, and those unique to radial keratotomy--complete failure of the procedure, marked undercorrection, marked overcorrection, and induced astigmatism. Symptoms due to anisometropia were prominent in the latter group who considered themselves visually disabled by the surgery. Radial keratotomy, like all surgical procedures, is liable to complications that may lead to visual impairment, blindness, or loss of an eye.
