目的探讨视网膜脱离硅油注入术后白内障的手术治疗方法及各项术前、术后注意点。方法回顾性分析了本科2003.1～2004.5视网膜脱离硅油注入术后并发白内障病例共35例35眼。硅油注入术后时间6～90月,平均19.7月。术后视力开始下降即白内障发生时间2～48月,平均10.1月。采用传统晶体囊外摘除术或超声乳化白内障摘除+人工晶体植入术。其中术前前房硅油合并继发性青光眼者未放置人工晶体行6∶00虹膜周切。采用白内障摘除联合硅油取出术8眼,其中晶体囊外摘除+硅油取出术3眼,超声乳化白内障摘除+硅油取出术5眼。结果经过随访,视力提高33眼,占94.29%;视力达到视网膜脱离术后白内障发生前的最佳视力的有25眼,占71.43%。最高矫正视力达0.4;脱盲率为60%。结论白内障摘除手术对于提高视网膜脱离硅油注入术后并发白内障患者的视力,改善其生活质量有很大的帮助,并有利于对眼底视网膜情况的随访。
Objective To investigate the surgical treatment of retinal detachment after silicone oil injection and its preoperative and postoperative attention points. Methods A retrospective analysis of undergraduate 2003.1 ~ 2004.5 retinal detachment after implantation of silicone oil cataract cases were 35 cases 35 cases. Silicone injection time 6 to 90 months, an average of 19.7 months. Postoperative visual acuity began to decline that cataract occurred 2 to 48 months, an average of 10.1 months. The use of conventional extracapsular lens extraction or phacoemulsification + intraocular lens implantation. Preoperative anterior chamber silicone oil with secondary glaucoma were not placed intraocular lens 6:00 iris circumcision. Eight eyes were removed with cataract extraction combined with silicone oil, among which three were extracapsular cataract extraction + silicone removal, and five were silicone removal. Results After follow-up, the visual acuity increased by 33 eyes (94.29%), and the best visual acuity before the onset of cataract after retinal detachment was 25 eyes (71.43%). The highest corrected visual acuity of 0.4; blindness rate of 60%. Conclusion Cataract extraction surgery is helpful to improve visual acuity and quality of life of patients with retinal detachment after silicone oil injection. It is also helpful for follow-up of fundus retina.
