title: Transient central corneal steepening after radial keratotomy.
abstract: Three case studies are presented illustrating topographic transient central steep island following radial keratotomy. Three stages are apparent: first, a central corneal steepening; next, an overcorrection with exaggerated central flattening; and, finally, the final refractive correction. The steepening is probably caused by temporary midperipheral swelling of the cornea.
