ROME — Patients with keratoconus who underwent anterior lamellar keratoplasty using a femtosecond laser had “good preliminary results” at 6 months, said Methiye Nurozler. He presented his findings here at the winter meeting of the European Society of Cataract and Refractive Surgeons.

Six eyes of six patients with keratoconus who were unable to tolerate contact lenses were operated on using IntraLase femtosecond laser to perform anterior lamellar keratoplasty (ALK), Dr. Nurozler said. The laser performed lamellar cuts with a thickness of 400 µm in the donor eyes as well as the recipient eyes. Stromal beds were prepared at a depth of 150 µm. Donor lamellas that were 0.1 mm to 0.4 mm larger in diameter than the recipient beds were sutured in place.

Dr. Nurozler said all six patients “were free of pain and irritation starting from the first day following the surgery.”

He said there were no complications. Anterior chamber depth decreased, and flattening and thickening of the cornea resulted, he said.

“IntraLase-assisted ALK is a promising approach for the management of keratoconus,” he said.
