Objective:
To determine the visual and refractive outcome of LASEK for the correction of residual myopia and astigmatism after laser in situ keratomileusis (LASIK).
Methods:
In this prospective study of noncomparative case series, LASEK was performed with minimum of 6 months in 66 eyes (34 patients) that developed myopic regression after LASIK. Mean follow-up was 13.2 months after laser ablation (12 to 18 months). The postoperative symptom, epithelial flap, wavefront aberration, and haze formation were investigated.
Results:
Postoperative results revealed a reduction in the residual myopia and astigmatism. Higher order aberration was increased postoperatively. No eye lost best corrected Snellen visual acuity. No intraoperative or postoperative complications occurred.
Conclusions:
LASEK performed in eyes with myopic regression after LASIK result in an improvement in uncorrected visual acuity.
