摘    要:目的:评价晶状体囊袋张力环(capsular tension ring,CTR)在先天性晶状体半脱位超声乳化吸除术中的应用价值.方法:对18例31眼先天性晶状体半脱位患者行晶状体超声乳化吸除联合CTR及 IOL 植入术.测量手术前后视力,使用Image-ProPlus v6.0软件测定IOL位置,观察术中术后并发症.结果:所有患者术后裸眼视力均较术前提高.术后人工晶状体均有不同程度的偏心,其中2眼人工晶状体偏位大于2mm并逐渐加重,于术后3mo行Ⅱ期手术将偏位最大方向CTR缝合固定于巩膜后恢复正位.结论:在白内障合并晶状体半脱位患者中行晶状体超声乳化吸除术中植入CTR是安全有效的方法,有利于保持囊袋的稳定,便于手术操作,保持人工晶状体的基本正位,减少手术并发症.如术后晶状体偏位加重可Ⅱ期行CTR巩膜缝合固定术.

关 键 词:先天性晶状体半脱位  晶状体超声乳化吸除术  囊袋张力环

Abstract:AIM: To evaluate the clinical results of capsular tension ring(CTR)implantation in phacoemulsification for eyes with congenital lens subluxation.

METHODS: This study comprised 18 patients(31 eyes)with congenital ectopia lentis. All patients received phacoemulsification with CTR and intraocular lens(IOL)implantation. Visual acuity before and after surgery were examined. IOL decentration were measured with Image-Pro Plus image processing software. The complications were also recorded preoperatively and postoperatively.

RESULTS: Uncorrected vision of all eyes increased after surgery, and all cases had different degree of IOL decentration after surgery. Two eyes received CTR scleral fixation 3mo after surgery because the IOL decentration aggravated during the follow-up period.

CONCLUSION: Phacoemulsification with CTR and IOL implantation is effective and safe for congenital lens subluxation. The implantation of CTR increase the stability of the capsular bag, improve the safety of surgery, and maintain the right position of IOL. CTR scleral fixation is a effective supplement for progressive cases.

Keywords:congenital lens subluxation   phacoemulsification   capsular tension ring
