Clinical application of capsular tension ring in high myopia patients with after-cataract

Objective To discuss the clinical surgical effects of capsular tension ring (CTR) in high myopia patients with after-cataract. Methods A total of 320 cases (545 eyes) with after-cataract in high myopia in our hospital from June 2009 to December 2011 were chosen,all cases were previously performed the refractive surgery.The patients were randomly divided into control group (156 cases,270 eyes) and observed group (164 cases,275 eyes).The patients in control group were treated with phacoemulsification and intraocular lens implantation,and the patients in observed group were treated with capsular tension ring in addition.The follow-up time was 18 months,the intraoperative and postoperative complications in two groups were observed,and the visual acuity and intraocular pressure at the final follow-up were recorded,the recurrence of cataract was also observed. Results The preoperative and postoperative visual acuity in control group were 0.23±0.09 and 0.37±0.10,which in observed group were 0.25±0.08 and 0.45±0.09,the postoperative visual acuity in two groups were improved,compared with pre-operation,there were statistical differences (both P0.05);The postoperative visual acuity in observed group was better than that in control group,there was statistical difference(P0.05).The postoperative intraocular pressure in two groups were all decreased,compared with pre-operation,there were statistical differences(both P0.05);The postoperative intraocular pressure in observed group was lower than that in control group,there was statistical difference(P0.05).There were statistical differences in recurrence of cataract and complication rates between two groups(both P0.05). Conclusion As a new type of cataract surgery supporting material,CTR can effectively improve the clinical surgical effects in high myopia patients with after-cataract.
