Wedge resection in the cone after failed refractive surgery in a patient with keratoconus.

A 30-year-old man with keratoconus in the right eye had radial keratotomy in the left eye. Two pairs of corneal relaxing incisions (CRIs) were made in the right eye to flatten the central cornea and reduce high astigmatism. The right eye required an enhancement, and two additional arcuate CRIs were made. A corneal ulcer developed in the right eye, with infiltrates in the incision and corneal thinning. Although the second set of CRIs resulted in more regular astigmatism, the corneal thinning and ulcer caused regression at two months postoperatively. A wedge resection was performed to even the irregular astigmatism. The results are presented.
