Excimer phototherapeutic keratectomy for corneal subepithelial cryoglobulin deposits.

A 64-year-old man with a history of cryoglobulinemia and repeated scraping of immunoglobulin deposits from both superficial corneas presented with gradual decrease in vision and progressive hyperopia caused by circumferential redeposition of the cryoglobulins in his corneas. He had debridment of the deposits combined with phototherapeutic keratectomy to smooth the corneal surface. Visual acuity and reading capacity markedly improved, and hyperopia regressed by 5.75 diopters (D) in the right eye and 5.25 D in the left. Follow-up was 3 years.
