角膜屈光手术后增效手术的研究进展

Research Progress of the Corneal Enhancement Refractive Surgery

初次角膜屈光手术后的患者,由于各种原因导致术后屈光异常(残余屈光不正)或者视觉质量不佳,要求手术修正,这种在手术条件允许的前提下,再次进行且以提高视力、改善初次手术效果为目的的屈光手术即为增效手术。现笔者对增效手术的流行病学、术前术后评估和具体方法等进行综述。

After the primary corneal refractive surgery,patients with postoperative refractive abnormalities(residual refractive errors)or poor visual quality require another surgical correction due to various reasons.This secondary refractive surgery,which is aimed at improving visual acuity and quality,is called enhancement surgery.This article reviews the epidemiology,preoperative and postperative evaluation,and specific methods of enhancement surgery.
