高度近视合并白内障超声乳化手术临床分析

目的探讨超声乳化术治疗高度近视合并白内障的手术疗效。方法回顾性分析2008年1月至2010年7月，行白内障超声乳化吸出联合低度数或负度数人工晶状体植入治疗高度近视合并白内障89例（102眼）的手术效果和并发症。结果术后3个月矫正视力〈Q05者3眼，0.05-0.1者5眼，0.12-0.25者13眼，0.3．0.4者38眼，0.5-0.6者36眼，≥0.8者7眼。脱盲率97．06％，脱残率79．41％。其中矫正视力≥n5者共42眼，眼轴〈30mm者38眼（51．35％），眼轴≥30mm者4眼（14．29％），差异有统计学意义（χ2=11．52，P〈0．05）。并发症主要有：术中撕囊失败7眼（6．86％），后囊破裂5眼（4．91％），悬韧带断裂4眼（3．92％），术后角膜水肿15眼（14．71％），葡萄膜反应11眼（10．78％），经治疗后均在1周内消退，继发性视网膜脱离2眼（1．96％），手术后复位。结论高度近视合并白内障行白内障超声乳化吸出联合人工晶状体植入，手术并发症少，术后视功能恢复较好。

Clinical analysis of phacoemulsification for cataract with high myopia

Objective To investigate the clinical effects of phacoemulsification for cataract with high myopia. Methods Retrospective analysis of the clinical effects and complications of phacoemulsification and implantation of low or nega- tive - power intraocular lenses in 89 patients（102eyes） with high myopia and cataract who visited our hospital from Janu- ary 2008 to July 2010. Results Three months after operation, corrected visual acuity were less than 0. 05 in 3 eyes, 0.05to0.1 in5 eyes,0.12 to0.25 in 13 eyes,0.3 to0.4 in 38 eyes,0. 5 to0.6 in 36 eyes,0.8 or better in7 eyes. Got rid of blind rate was 97. 06% , got rid of disability rate was 79.41%. 38 eyes （51.35% ）which the axial lengths were less than 30mm and 4 eyes（ 14. 29% ）which the axial lengths were more than 30mm had visual acuity 0. 5 or bet- ter, the difference was statistically significant （ χ2 = 11.52, P 〈 0. 05 ） Main complications ： intraoperative capsulorhexis failure in 7 eyes （6. 86% ）, posterior capsular rupture in 5 eyes （4. 91% ）, suspensory ligament rupture in 4 eyes （3.92%） ;Corneal edema in 15 eyes（ 14.71% ）and uveal inflammatory response in 11 eyes（ 10. 78% ）were all recovery in one week after treatment, retinal detachment in 2 eyes（ 1.96% ） were reattached by surgery. Conclusion Phacoemul- sification and implantation intraocular lenses in patients with high myopia and cataract have fewer complications and re- covery of visual function better after operation.
