西藏白内障手术后低视力原因的初步探讨

A preliminary study in the reasons of low vision after cataract surgery in Tibet.

目的分析西藏白内障手术后低视力的原因,探讨提高西藏白内障手术效果的方法。方法对82例(82眼)白内障手术后者进行小孔视力、非接触眼压、裂隙灯显微镜、直接检眼镜、B超及散瞳后的90D前置镜眼底检查,分析白内障术后低视力的原因。结果 82眼中术后达到脱残标准(矫正视力≥0.3)的36眼,脱残率43.90%;脱盲(矫正视力≥0.05)64眼,脱盲率78.05%。白内障术后低视力的原因按发生率依次为黄斑变性15眼,屈光不正6眼,后发障5眼,无晶状体眼4眼,角膜变性3眼,瞳孔膜闭3眼,青光眼2眼,视网膜脱离2眼,人工晶状体偏位2眼,其他4眼。结论通过白内障手术后眼部紫外线的防护、术后及时的随诊和正规的应用有效的药物、尽可能减少可避免的手术并发症以及防治后发障、提高手术技术等办法可以提高西藏白内障的手术效果。

Objective Analysis the reason of low vision after cataract surgery in order to find methods to improve the results of cataract surgery in Tibet. Methods Examine BCVA, NCT, slit lamp, direct ophthalmoscope, B scan and 90D supplementary lens of 82 eyes in 82 patients. Results Visual acuity in 36 patients of 82 eyes is above 0. 3. VA in 64 patients is above 0.1. The reasons of low vision after cataract surgery are macular degeneration 15 eases, refractive error 6 cases, posterior capsular opacity 5 cases, aphakia 4 cases, cornea degeneration 3 cases, occlusion of pupil 3 cases, glaucoma 2 cases, retinal detachment 2 cases, IOL dissymmetry 2 cases, others 4 cases. Conclusion Protecting the post operative eyes from ultraviolet, following - up after surgery, using proper drugs and diminishing surgery complications may benefit the outcome of cataract surgery in Tibet.
