白内障超声乳化两种透明角膜切口比较

Comparison of two kinds of transparent corneal incision of cataract phacoemulsification

目的:比较白内障超声乳化大小两种透明角膜切口术后视力及散光度数的差异。方法:选择老年性白内障160例160眼分别行白内障超声乳化5.5mm透明角膜切口(A组)与3.2mm透明角膜切口(B组)植入术后1wk;1,3,6mo进行视力及散光度数比较。结果:术后1wk裸眼视力A组明显低于B组,术后1,3,6mo裸眼视力A组与B组比较无明显差异;术后1wk;1mo角膜散光度数比较A组明显高于B组,术后3,6mo角膜散光度数A组与B组比较无明显差异。结论:基层医院面向经济欠发达的农村地区开展5.5mm透明角膜切口硬质人工晶状体植入术是行之有效的。

AIM： To compare the difference in the vision and astigmatism degree after the cataract phacoemulsification with two types of transparent corneal incision.METHODS： Selected 160 senile cataract patients were divided into group A and group B. Group A received the cataract phacoemulsification with 5.5mm transparent corneal incision, while group B was 3.2mm, Then the difference in the vision and astigmatism degree were compared in the 1st week, the 1st, the 3rd and the 6th month after operation.RESULTS： The unaided vision of group A was obviously worse than that of group B the first week after operation. There was no obvious difference the first, third and sixth month after operation. The astigmatism degree of group A was obviously higher than that of group B the first week and the first month after operation. There was no obvious difference in corneal astigmatism degree the third and sixth month after operation. CONCLUSION ： The implantation of rigid intraocular lens with 5.5mm transparent corneal incision is available for the elementary hospital when they serve the rural area.
