Femtosecond, conventional microkeratomes show similar results

WASHINGTON — No statistically significant differences were seen in the outcomes of LASIK with flaps created by either a femtosecond laser microkeratome or a conventional blade microkeratome, according to a surgeon speaking here.
Maria R. Chalita, MD, discussed the results of a study comparing the IntraLase FS laser and the Moria M3 microkeratome at the American Society of Cataract and Refractive Surgery meeting. She said there were no statistically significant differences between the results with the two microkeratomes regarding postoperative best corrected visual acuity, spherical equivalent and higher-order aberrations.
Dr. Chalita compared 129 eyes that underwent wavefront-guided LASIK after flap creation with the IntraLase with 282 eyes that underwent wavefront-guided LASIK after flap creation with the Moria M3.
The differences between the two groups were minimal, she said. Both groups had increases in spherical aberration, but the difference was not statistically significant. There were also slight increases in vertical coma in the IntraLase group and horizontal coma in the Moria group, she said.
