title: [Correction of ocular aberrations in custom and standard LASIK retreatments].
abstract: OBJECTIVE
  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.
