[Correction of ocular aberrations in custom and standard LASIK retreatments].

PURPOSE: To compare the correction of ocular aberrations between custom and standard LASIK retreatment.

METHODS

Prospective, randomized trial with paired eye control of 74 eyes from 37 patients who underwent LASIK retreatment. Each patient underwent retreatment using Zyoptix LASIK (Bausch & Lomb) in 1 eye and Planoscan LASIK (Bausch & Lomb) in the fellow eye. Correction of ocular aberrations was compared between custom and standard LASIK retreatments.

RESULTS

At 6 months, there was a statistically significant reduction in defocus, astigmatism, coma, spherical aberration, second, third, higher-order and total aberration in Zyoptix eyes. There was a statistically significant reduction in defocus, second-order and total aberration in Planoscan eyes.

CONCLUSIONS

Custom retreatment was statistically superior than standard retreatment for correction of lower and higher ocular aberrations.
