【摘要】：目的比较一期改良式囊袋张力环(modified capsular tension ring,MCTR)巩膜固定或二期囊袋张力环(capsular tension ring,CTR)-囊袋复合体巩膜固定治疗中重度晶状体不全脱位的临床效果。方法回顾性研究。收集我院2012年1月至2015年12月中重度(120°~270°)晶状体不全脱位患者30例43眼,均在局部麻醉下行超声乳化白内障吸出及MCTR或CTR和IOL囊袋内植入术,A组23眼均采用MCTR联合IOL植入术,一期巩膜固定;B组20眼均采用一期CTR联合IOL植入术,3~6个月后行二期CTR-囊袋复合体巩膜固定术。观察两组术后6个月最佳矫正视力、术后囊袋复合体的位置及并发症等情况。结果术后6个月,A组87%患眼最佳矫正视力≥0.6,B组95%患眼最佳矫正视力≥0.6,两组相比差异无统计学意义(P0.05)。术后所有CTR、IOL均位于囊袋内,囊袋中度收缩偏中心A组2眼,B组1眼,两组发生率相比差异无统计学意义(P0.05),均行YAG激光前囊膜松解后缓解。术后早期(1个月)并发症:前房渗出膜A组3眼,B组1眼;一过性高眼压A组5眼,B组2眼,两组两种并发症发生率相比差异均无统计学意义(均为P0.05)。术后远期(6个月)并发症:后发性白内障A组3眼,B组1眼,两组相比差异无统计学意义(P0.05),均行YAG后囊切开术。结论一期MCTR巩膜固定或二期CTR-囊袋复合体巩膜固定术后囊袋复合体的位置和稳定性均良好,对中重度晶状体脱位治疗均有效。
[Abstract]:Objective to compare the clinical effect of scleral fixation with modified pouch tension loop modified capsular tension (MCTR) or capsular tension tension ring-scleral fixation (CTR- scleral fixation) in the treatment of moderate and severe dislocations of lens.Methods retrospective study.From January 2012 to December 2015, 30 patients (43 eyes) with moderate or severe dislocated lens were collected. All of them were treated with MCTR combined with IOL implantation under local anesthesia, phacoemulsification cataract extraction and MCTR or CTR and IOL pouch implantation in group A (23 eyes).20 eyes of group B were treated with CTR combined with IOL implantation for 3 ~ 6 months.The best corrected visual acuity (BCVA), the location and complications of the pouch complex in the two groups were observed 6 months after operation.Results at 6 months after operation, the best corrected visual acuity (BCVA) of 87% of the affected eyes in group A was 鈮，
