[Visual quality after custom versus standard LASIK retreatment].
OBJECTIVE
To evaluate visual quality after wavefront-guided LASIK versus standard LASIK in retreatment of primary LASIK for myopia and myopic astigmatism.


METHODS
A prospective study was performed with paired eye control of 74 eyes with LASIK retreatment. Each patient underwent retreatment using custom ablation (Zyoptix, Bausch & Lomb) in 1 eye and standard ablation LASIK (PlanoScan, Bausch & Lomb) in the contralateral eye. A complete ophthalmologic examination was performed, including evaluation of glare test and contrast sensitivity test, with a follow-up of 6 months.


RESULTS
Zyoptix eyes showed better results of glare test and contrast sensitivity test than the contralateral eyes.


CONCLUSIONS
Wavefront-guided LASIK produces better visual quality than standard LASIK in the retreatment of refractive errors after primary LASIK.
