摘要
目的：评价再次ＬＡＳＩＫ（准分子激光原位角膜磨镶术 ｅｘｃｉｍｅｒ ｌａｓｅｒ ｉｎ ｓｉｔｕ ｋｅｒａｔｏｍｉｌｅｕｓｉｓ，ＬＡＳＩＫ）矫正残余近视的效果、可预测性、安全性。方法：对４０只眼（３２人）ＬＡＳＩＫ术后屈光欠矫的患者行二次手术，两次手术间隔时间３～２４个月。分别在二次术后３天、１、３和６个月随访观察。结果：术后各随访时间患眼平均裸眼视力（ＵＣＶＡ）较术前明显提高（Ｐ＜０．０１），最佳矫正视力（ＢＣＶＡ）与术前无显著差异；术后平均屈光度较术前减少，差异有显著性（Ｐ＜０．０１），切削直径适量增大可减少术后屈光回退（ｏｄｄｓ ｒａｔｉｏ＝２． ６８５）。结论：二次ＬＡＳＩＫ手术是必要、安全、可行的。
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(P<0.01), whereas best-corrected visual acuity(BCVA) had no significant difference. The mean postretreatment refraction decreased significantly than before (P<0.01). 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.
