Corre？？o das aberra？？es oculares nos retratamentos de LASIK personalizado e convencional

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.
