A technique for preparing corneal lamellar donor tissue using simplified keratomileusis

A technique is described for producing lamellar buttons from donor corneas using modified keratomileusis. Although refractive keratoplasty is complex, producing planopower corneal discs is much simpler. Accuracy in preparing lamellar tissue of known thickness is potentially greater with keratomileusis than free-hand dissection and should produce better visual results. Eye banks could store precut lamellar buttons in various thicknesses and thereby decrease the amount of time spent in the operating room during lamellar keratoplasty.
