Femtosecond Laser (WaveLight FS200) Customized Keratoplasty for Keratoconus: Case Report

PURPOSE: To describe a case of a 52-year-old man with severe keratoconus who underwent femtosecond laser–assisted keratoplasty with the WaveLight FS200 femtosecond laser (Alcon Laboratories Inc). METHODS: The donor and recipient corneas were cut in a mushroom-shaped pattern. The laser parameters used on this platform for the donor and recipient corneas are described. RESULTS: Corrected distance visual acuity improved by 3 weeks postoperatively. Mean keratometry decreased from 60.00 to 46.00 diopters. CONCLUSIONS: This patient underwent a mushroom-shaped keratoplasty with the femtosecond laser to maximize preservation of his own endothelium. Increased energy and/or decreased spot line separation may be required depending on the degree of corneal edema or scarring involved.
