Since the number of patients undergoing radial keratotomy has increased, more have required contact tens fitting to correct residual ametropia. A number of practitioners suggest that the postoperative changes stabilize after 12 months, so contact lens lining on the unusual resultant conical topography can begin. This paper discusses corneal and refractive changes that are revealed even when correctly lining lenses are worn 1–5 years postoperatively. These changes indicate that lens wear may influence corneal topography and refraction even several years after radial keratotomy.
