Objective:

Compare the pre- and postoperative visual and refractive results in myopic patients operated with surface techniques and aspheric ablation profile.

Methods:

An open randomized controlled experimental study, equivalence and non-inferiority type was carried out in 160 patients (320 eyes). In the study, two groups were formed: the first group was made up of 80 patients (160 eyes), who underwent Photorefractive keratectomy - mitomycin C, and the second group made up of 80 patients (160 eyes), underwent LASEK - mitomycin C.

Results:

Women with mild myopia and ages between 21 and 29 years old predominated in both groups. At three months, the Photorefractive keratectomy - mitomycin C group had AVSC 0.97 ± 0.09; sphere 0.003 ± 0.21; cylinder -0.09 ± 0.30 and spherical equivalent -0.04 ± 0, 2. 3. In the Photorefractive keratectomy - mitomycin C group, AVSC 0.96 ± 0.11; sphere -0.007 ± 0.24; cylinder -0.08 ± 0.25 and spherical equivalent -0.06 ± 0.26.

Conclusion:

Both surgical techniques improved significantly refractive and visual results, but there was no difference between them.
