BLADELESS LASIK & ABERRATIONS

The use of the femtosecond laser to perform bladeless LASIK or the mechanical microkeratome to perform traditional LASIK results in similar optical aberrations being produced in the cornea after LASIK The study results showed that 43 out of 46 eyes in the microkeratome group (93.5%) and 41 out of 48 eyes in the femtosecond group (85.4%) had uncorrected distance visual acuity of 20/20 or better at 48 months after surgery. All eyes in both groups attained uncorrected distance visual acuity of 20/30 or better.

The results of this study suggest that whether patients are having LASIK with a microkeratome or LASIK with a femtosecond laser to create the flap, they should have either a custom wavefront optimized LASIK procedure or a custom wavefront guided LASIK procedure in order to avoid inducing higher order aberrations.
