Lasik Flap Options
Previously, a microkeratome (MK) was used to form a flap for LASIK. The MK is a miniature automated device which can produce a thin, lamellar cut in corneal tissue. Eventually, the femtosecond laser (FL), a precise, high speed cutting device was adapted for use in LASIK surgery. The Zeiss Visumax™, Intralase™ and Ziemer are all examples of FLs. The LASIK procedure performed with a femtosecond laser is sometimes called “All-Laser LASIK,” “Bladeless LASIK,” or Z-LASIK™.
The goals of flap formation are a smooth bed, consistent flap thickness, flap hinge away from the treatment area, and safety with no damage to the flap. The FL flap creates a more uniform flap thickness, with a lower complication rate. However, no procedure is complication free, and flap complications can occur even if created as Bladeless LASIK.
Evidence suggests that thinner flaps result in better visual performance for patients, in addition to preserving corneal integrity and reducing the incidence of Dry Eye after LASIK. That’s why years ago Dr. Roholt instituted “thin-flap LASIK” even with the MK.
At Roholt Vision Institute, the Zeiss Visumax™ and Ziemer femtosecond lasers (Z-LASIK) are used for Bladeless, All-Laser LASIK. The Ziemer is a second-generation, solid-state laser producing a more focused and faster treatment than the Intralase™. The Zeiss Visumax™ uses gentle, very low vacuum and low energy, and it’s superior accuracy makes it the only laser approved for the SMILE procedure, in addition to creation of exquisite LASIK flaps.
