Abstract

Objective: To evaluate the effectiveness, predictability and safety of LASIK retreatment for corecting residual myopia. Method: Forty eyes(32 patients) underwent secondary LASIK at 3～24 months after primary LASIK procedure. Following-up were three days, 1,3 and 6 months after LASIK retreatment respectively. Results: After reoperation, mean uncorrected visual acuity(UCVA) improved significantly(P0.01), whereas best-corrected visual acuity(BCVA) had no significant difference. The mean postretreatment refraction decreased significantly than before (P0.01). There was increased stability of refraction with the ablation diameter used (odds ratio=2.685). Conclusions: Secondary LASIK was an effective, safe method to treat regression after primary LASIK for high myopia.
