晶状体半脱位白内障超声乳化术中囊袋张力环的应用观察

目的:评价晶状体囊袋张力环(capsular tension ring,CTR)在白内障合并晶状体半脱位行超声乳化白内障吸除术中的应用价值。方法:对15例16眼白内障合并晶状体半脱位患者行超声乳化白内障吸除术,术中连续环行撕囊后植入CTR,超声乳化摘除白内障,囊袋内植入后房型人工晶状体,若晶状体半脱位>1/2需植入固定孔型CTR,将CTR固定孔上的聚丙烯线固定于悬韧带离断一侧板层巩膜壁上。结果:所有植入的人工晶状体均位于正位。术后随诊3~9mo,矫正视力0.1~0.4者5眼,0.5~0.8者8眼,>0.8者3眼。结论:在白内障合并晶状体半脱位患者行超声乳化白内障吸除术中植入囊袋张力环是安全有效的方法,有利于保持囊袋的完整,便于后房型人工晶状体植入,防止人工晶状体的偏位,减少手术并发症,术后视力恢复快。

Clinical use of capsular tension ring during phacoemulsification in subluxated lens

·AIM:To evaluate the efficiency of capsular tension ring(CTR)implantation during phacoemulsification in patients with subluxated lens and cataract.·METHODS:Phacoemulsification combined with intraocular lens implamtation(IOL)was performed on 16 eyes of 15 patients.CTR was implanted following continuous curvilinear capsulorhexis,cataract was extracted by phacoemulsification,and posterior chamber IOL implantation was implanted in capsular bag.If the lens subluxation>1/2,fixed pass CTR should be implanted,and the propylene-line on CTR fixed holes should be fixed on the lamellar scleral wall on the broken side of the suspensory ligament.·RESULTS:IOL position in all cases were normal.The follow-up time lasted for 3-9 months.The corrected visual acuity was 0.1-0.4 in 5 eyes,0.5-0.8 in 8 eyes,over 0.8 in 3 eyes.·CONCLUSION:CTR implantation during phacoemulsification is a safe and effective method for subluxated lens with cataract.It can maintain the sac integrity,facilitate posterior chamber intraocular lens implantation,prevent deviation of IOL,reduce postoperative complications and accelerate visual acuity recovery.·
