Radial keratotomy for intolerable myopia after penetrating keratoplasty.
Radial keratotomy was used to treat intolerable myopia in nine patients aged 56 to 86 years who had previously undergone penetrating keratoplasty and intraocular lens placement. The degree of myopia ranged from -5.25 to -9.25 diopters spherical equivalent before radial keratotomy. An eight-cut radial keratotomy with either a 4.0- or 4.50-mm central clear zone was performed on all patients. One year after the radial keratotomy, the spherical equivalent ranged from -1.25 to +1.63 diopters, which rendered all patients spectacle tolerant. Endothelial cell counts done before and one year after radial keratotomy demonstrated no marked loss of endothelial cell density. No complications were seen as a result of the radial keratotomy.
