乍得光明行488例白内障临床特点及手术效果分析

Clinical Characteristics and Surgical Efficacy of 488 Cases of Cataract in Chad Brightness Action

目的:观察乍得光明行488例白内障的临床特点及手术效果。方法:回顾分析2018年和2019年中国(江西)光明行医疗队两次赴乍得施行超声乳化白内障吸除术341例(341眼)和小切口囊外白内障摘除术147例(147眼)的临床资料,观察术后不同时期视力及并发症。结果:术前视力光感~0.04者392眼(80.33%),0.05~0.1者87眼(17.83%);人工晶状体度数主要集中在21.0D^26.5D (76.77%),峰值23.0D^24.5D (31.15%)。术后7天,裸眼视力光感~0.04者27眼(5.53%),0.05~0.1者42眼(8.61%),0.12~0.25者82眼(16.80%),0.3~0.5者267眼(54.71%),≥0.6者70眼(14.34%);裸眼视力≥0.3者Phaco组高于ECCE组,两组裸眼视力分布具有统计学差异(X2 = 31.02, P 【0.01),总体脱盲率94.47%,脱残率69.06%。后囊破裂17眼(3.48%),未植入IOL5眼(1.02%),角膜水肿97眼(19.88%),眼压高31眼(6.35%),眼前节葡萄膜炎17眼(3.48%),未发生脉络膜暴发性出血、玻璃体炎症或囊泡性角膜炎。结论:乍得白内障治疗现阶段处于复明手术阶段,眼部合并症较多,白内障病情相对较复杂,人工晶状体度数偏高,酌情选择超声乳化及小切口白内障摘除手术效果良好、安全可靠。

Objective: To observe the clinical efficacy and characteristic of 488 cataract patients in Brightness Action, Chad. Methods: China (Jiangxi) Brightness Action Medical Team went to Chad in 2018 and 2019, retrospectively analyzed the clinical data of 341 cases (341 eyes) underwent phacoemulsification cataract extraction and 147 cases (147 eyes) underwent extracapsular cataract extraction in twice Brightness Action. The visual acuity and complications at 1 day, 1 week and 1 month after operation were analyzed. Results: The preoperative visual acuity was LP-0.04 in 392 eyes (80.33%), and 0.05 to 0.1 in 87 eyes (17.83%);The intraocular lens power is mainly concentrated in 21.0D - 26.5D (76.77%), the peak value is 23.0D - 24.5D (31.15%). Seven days after operation, the visual acuity was LP-0.04 in 27 eyes (5.53%), 0.05 - 0.1 in 42 eyes (8.61%) eyes, 0.12 - 0.25 in 82 eyes (16.80%), 0.3 - 0.5 in 267 eyes (54.71%), ≥0.6 in 70 eyes (14.34%). Phaco group has a higher proportion of visual acuity in ≥0.3 than ECCE group, the difference in visual acuity distribution between the two groups is statistically significant (X2 = 31.02, P
