角膜屈光手术后屈光回退的手术治疗进展*

屈光回退是角膜屈光手术后的并发症之一,其治疗方法主要为药物治疗和手术治疗。对于需要再次手术的患者,应根据初次手术方式、距离初次手术时间、回退度数,在充分评价角膜情况后合理选择增效术,确保手术的安全性和有效性。目前,准分子激光原位角膜磨镶术和飞秒激光小切口角膜基质透镜取出术是治疗近视和近视散光的主要手术方式。本文就两者术后屈光回退手术治疗的适应症、不同增效术的优缺点及注意事项作一综述。

Advance in Surgical Treatment of Refractive Regression after Corneal Refractive Surgery*

ABSTRACT: Refractive regression is one of the postoperative complications of corneal refractive surgery. The therapies mainly include pharmacotherapy and surgical treatment. For patients who need reoperation, options of enhancement should be made properly after adequate evaluation of corneal condition according to the primary surgical method, the time length since primary operation and the degree of regression, to ensure the safety and effectiveness. At present, the major surgical methods for correction of myopia and myopic astigmatism are laser in situ keratomileusis and small incision lenticule extraction. This article reviews the indications for surgical treatment of refractive regression after both methods, the advantages and disadvantages of different enhancement procedures and their considerations.
