PURPOSE
To review refractive regression and current therapeutic options for patients who have residual refractive error after LASIK.
METHODS
An extensive literature search using PubMed was performed for terms such as "LASIK," "PRK," "enhancement," "overcorrection," "undercorrection," "re-lift," "mini-flap," and related terms.
RESULTS
The presence of residual refractive error following LASIK is a challenging situation. After excluding anatomical causes (eg, ocular surface disease, cataract, and macular pathology) and intraoperative flap complications, evaluation of the residual stromal bed must be performed. Depending on the length of time since primary LASIK, procedures such as flap re-lift, flap re-cut, and surface ablation may be performed.
CONCLUSIONS
Residual refractive errors can be seen after LASIK surgery and may benefit from an enhancement procedure. Different options are available for enhancement, each requiring proper evaluation and an analytical approach to make the procedure safe and effective. [J Refract Surg. 2017;33(2):116-127.].
目的
回顾接受准分子原位角膜磨镶术（LASIK）后仍存在残余屈光不正患者的屈光回退情况及当前的治疗选择。
方法
使用PubMed进行广泛的文献检索，检索词包括“LASIK”“准分子激光角膜切削术（PRK）”“增效手术”“过矫”“欠矫”“再次掀起瓣”“微型瓣”及相关术语。
结果
LASIK术后存在残余屈光不正是一种具有挑战性的情况。排除解剖学原因（如眼表疾病、白内障和黄斑病变）及术中瓣并发症后，必须对残余基质床进行评估。根据初次LASIK术后的时间长短，可进行诸如再次掀起瓣、再次切削瓣及表面切削等手术。
结论
LASIK手术后可见残余屈光不正，可能从增效手术中获益。增效手术有不同的选择，每种都需要适当评估和分析方法，以使手术安全有效。[《屈光手术杂志》。2017；33(2):116 - 127。]
