Keratoconus and corneal stability after radial keratectomy in the fellow eye: case report.
Keratoconus has usually been described as bilateral but asymmetric disease. Corneal ectasia is one of the long-term complications of modern refractive surgery, especially those submitted to laser in situ keratomileusis (LASIK). We describe a patient with keratoconus in the right eye that was submitted to radial keratectomy (RK) in the left eye 19 years ago with no progression of the ectatic cornea and no complications related to the refractive surgery. Because unilateral keratoconus is rare, we believe that RK was performed on an already ectatic cornea (not clinically detected) or with fruste keratoconus. However, neither corneal ectasia progressed, nor ectasia was induced by RK in the fellow eye.
