To review the indications, techniques, and results of retreatment LASIK.
Review of the literature and the authors' experience.
Patient selection is the key to successful LASIK enhancement. The enhancement procedure should generally be undertaken 3 months after the initial LASIK procedure. Relifting of the flap may be done easily within 1 year of previous LASIK surgery. A new LASIK flap is required in cases with previously complicated LASIK. LASIK retreatment by lifting the flap is an effective and safe procedure. Overall improvement is seen in uncorrected visual acuity (> or = 20/20 and > or = 20/40) and postoperative spherical equivalent refraction within +/- 0.5 D and +/- 1.0 D.
LASIK retreatment is an effective modality to treat regressions and residual refractive errors.
回顾再次准分子激光原位角膜磨镶术（LASIK）的适应证、技术及结果。
文献回顾及作者经验总结。
患者选择是成功进行LASIK增效手术的关键。增效手术一般应在初次LASIK手术3个月后进行。在既往LASIK手术1年内，瓣的再次掀起操作相对容易。既往LASIK手术出现并发症的病例则需要制作新的LASIK瓣。通过掀起瓣进行LASIK再次手术是一种有效且安全的手术。裸眼视力（≥20/20和≥20/40）以及术后等效球镜度在±0.5D和±1.0D范围内均有整体改善。
LASIK再次手术是治疗屈光回退和残余屈光不正的有效方式。
