Blade vs. Laser: Is There a Difference in Outcomes?

David J. Tanzer, MD, San Diego

Perhaps the largest study to date to compare microkeratomes gives the laser the edge.

In the past year, there have been numerous reports comparing the results seen with the femtosecond laser to the visual results when a mechanical microkeratome is used. But few of these studies have included a large number of eyes.

In our most recent LASIK study conducted at the Naval Medical Center in San Diego, we set out to evaluate three keratome devices for LASIK flap creation: the Amadeus Microkeratome (Advanced Medical Optics); the Hansatome Microkeratome (Bausch & Lomb); and the IntraLase FS femtosecond laser (IntraLase).

The results show that there are some definitive clinical benefits to using the femtosecond laser for LASIK flap creation, chief among them being a much more reproducible flap.
