玻璃体切除术后白内障患者屈光预测误差来源的研究进展

Research progress on the sources of refractive prediction error in cataract patients after vitrectomy

随着微创玻璃体切除术(pars plana vitrectomy,PPV)的广泛开展和手术技术的提高,患者对手术后视觉质量的要求越来越高。白内障是PPV术后最常见并发症,而具有玻璃体切除史的白内障患者屈光变异大,预测难度高。本文综述了生物测量误差、人工晶状体屈光力计算公式选择以及有效晶状体位置预测等影响有玻璃体切除手术史的白内障患者术后屈光误差的主要因素,旨在为降低这一类特殊人群白内障术后屈光误差提供参考。

With the widespread application of minimally invasive vitrectomy and the improvement of surgical techniques,the demands of patients for better postoperative visual quality are increasing.Cataract is the most common complication after vitrectomy,whereas the refractive outcomes of cataract patients with prior vitrectomy are viable and difficult to predict.In this paper,the main factors affecting postoperative refractive error of cataract patients with a history of vitrectomy,such as biometric error,selection of intraocular lens calculation formulas and prediction of effective lens position,were reviewed in order to provide reference for reducing postoperative refractive error of this special group of cataract patients.
