Overcorrection is a frequent, significant complication of radial keratotomy (RK).1 Treatment of patients with overcorrected RK requires spectacle or contact lens correction of the hyperopia. Lindquist and associates2 described a technique of suturing the radial incisions to treat overcorrection following RK. In 1986, Mendez3 presented hexagonal keratotomy as a surgical treatment of hyperopia and overcorrection after RK. We describe a patient who required a penetrating keratoplasty for corneal scarring and irregular astigmatism following hexagonal keratotomy for an overcorrected RK, with multiple intersecting incisions.

Report of a Case.  —A 59-year-old man underwent RK of his left eye in July 1988. After surgery, his visual acuity was 20/20 with −6.25 sphere. Five months later, his visual acuity was 20/20 with +2.00 +2.50 × 175. 175. In December 1988, two additional radial cuts were performed in the horizontal meridian to correct the induced astigmatism. The astigmatism
