影响眼前后节联合手术屈光误差的相关因素分析

Analysis on related factors affecting refractive error of combined anterior and posterior segment surgery

白内障超声乳化吸除、IOL植入联合玻璃体切除术是一种既可矫正屈光亦可治疗眼底疾病的前后节联合手术,该术式具有术中更清晰的视野、术后早期视力提高及避免二次手术等多种优势,因此逐渐被用于治疗合并白内障的眼底病患者。与分期手术相比,前后节联合手术设备要求高、技术难度大、并发症更为多样,其中术后屈光误差(refractive error,RE)常常见诸报道。本文就近年来联合手术影响RE的相关因素、RE形成机制及控制措施进行综述,为手术适应证选择、并发症预防以及获得更满意的术后视功能提供参考。

Phacoemulsification and intraocular lens implantation combined vitrectomy (phacovitrectomy) cannot only correct refractive error but also treat vitreoretinal diseases. Due to its advantages of clearer intraoperative vision, postoperative visual function improvement and avoiding secondary procedures, phacovitrectomy has been increasingly used in patients with retinal and vitreous diseases combined with cataracts. Compared with traditional staged surgery, phacovitrectomy require special equipment and is higher technique-demanding and more complications. Several studies have shown that refractive error is commonly reported after surgery. In this article, the relevant influencing factors, formation mechanism and updated control strategy of RE were summarized to provide reference for the indication selection, avoidance of complications and more satisfactory postoperative visual function.
