Enhancement ablation for the treatment of undercorrection after excimer laser in situ keratomileusis for correcting myopia

摘要

Conclusion Undercorrection after LASIK can be corrected by an enhancement ablation of the stroma under the primary corneal cap with a 193 nm ArF ex- cimer laser, and the time for the enhancement of ablea- tion is at 3 months postoperatively. Objective to evaluate the treatment of under- correction after the excimer laser in situ keratomileusis (LASIK) for correcting moderate and high myopia. Methods An enhancement ablation was per- formed in 48 eyes of 39 patients who had undergone LASIK but remained in undercorrection.
