New microkeratome comparable to femtosecond laser for creating thin SBK flaps
SAN FRANCISCO — Flap creation with a new mechanical microkeratome was similar to femtosecond flap creation for sub-Bowman's keratomileusis, a surgeon said here.
Gustavo E. Tamayo, MD, described flap creation with the One Use-Plus microkeratome (Moria) at the American Society of Cataract and Refractive Surgery meeting.
"It produced comparable flaps to femtosecond technology, almost planar, a smooth bed, and certainly highly reproducible thinness, around 100 µm," Dr. Tamayo said. "The size is very adequate, and the cost is not comparable with any of the femtosecond technology. ... The Moria [One Use-Plus] is certainly an excellent answer to the femtosecond technology at a much lower price."
Dr. Tamayo cited earlier studies showing that microkeratome-created thin flaps were reproducible, with a high-quality stromal bed. Thin microkeratome flaps also offered rapid recovery, he said.
The study included 20 eyes that underwent SBK with the One Use-Plus and 20 eyes that underwent LASIK with the IntraLase femtosecond laser (Abbott Medical Optics).
One-month visual outcomes were similar to those achieved with femtosecond laser-created flaps, Dr. Tamayo said. Corneal hysteresis decreased among the IntraLase eyes by 5.7%; corneal hysteresis decreased by 10% in the One Use-Plus eyes.
