SINGAPORE — Using a femtosecond laser for penetrating keratoplasty produces favorable outcomes, Gerd Auffarth, MD, told attendees here at the Asia-Pacific Academy of Ophthalmology. He presented results from his first five cases using a femtosecond laser.

Patient ages ranged from 50 to 84 years old. Penetrating keratoplasty was indicated for granular corneal dystrophy, Fuchs endothelial dystrophy, familiar endothelial dystrophy, keratoconus and corneal scars after herpetic keratitis.

Dr. Auffarth said all procedures and postoperative recovery were uneventful.

The surgical technique involved a circular cut starting at 1,000 µm inside the anterior chamber and moving up toward the epithelium via the endothelium and stroma, he said. The cutting diameter was 7.8 mm for the recipient and 8.0 mm for the donor tissue. A double running Hoffman suture was applied to secure the corneal implant, Dr. Auffarth said.
