Conventional LASIK retreatment found superior to wavefront-guided retreatment

Conventional LASIK re-treatment produced superior results to wavefront-guided LASIK retreatment, according to results from a study.

George J.C. Jin, MD, PhD, and colleagues divided the 97 eyes into two groups, placing 74 eyes in the conventional group and 23 eyes in the wavefront-guided group. The procedures were performed with the LADARVision 4000 with and without CustomCornea (Alcon).

A spherical equivalent (SE) of ±0.50 D was achieved in 92%, or 68 of 74 eyes, in the conventional group, which began with a mean SE of –0.93. The wavefront-guided group started the process with a mean SE of –0.84, and 65%, or 15 of 23 eyes, achieved ±0.50 D, authors said.

Within the conventional group, 85% of the eyes resulted in an uncorrected visual acuity (UCVA) of 20/20 and 99% were 20/40. The wavefront-guided group had 35% at 20/20 and 100% at 20/40, according to the study.

Authors added that none of the eyes in the conventional group and 17% of the eyes in the wavefront-guided group lost two lines of their best-corrected visual acuity.

“In the study period with the current equipment, our results showed that conventional LASIK retreatment was superior to wavefront-guided LASIK retreatment in both efficacy and safety,” Dr. Jin said.

The study was published in the April issue of the American Journal of Ophthalmology.
