目的　评价 3 2mm阶梯状透明角膜切口植入折叠式人工晶状体后的临床效果。方法　采用上方 3 2mm阶梯状透明角膜切口 ,对 48例 5 0眼老年性白内障行超声乳化摘出 ,植入丙烯酸可折叠人工晶状体。结果　术后第 1天裸眼视力≥1 0者为 5 4%。角膜散光于 1月恢复至术前状态。术后于 3月角膜内皮丢失率为 10 40± 3 12 %。角膜厚度于术后 1周恢复至术前水平。结论　该手术视力恢复早 ,散光稳定快 ,对角膜内皮未产生过多的损伤。 Objective To evaluate the clinical effect of 3 2mm stepped clear corneal incision in the treatment of foldable intraocular lens. Methods 48 cases of 50 senile cataracts were phacoemulsified and implanted with foldable intraocular lens of acrylic acid. Results On the first day after operation, the uncorrected visual acuity ≥10 was 54%. Corneal astigmatism returned to preoperative status in January. Corneal endothelium loss rate was 10 40 ± 3 12% after surgery in March. Corneal thickness returned to preoperative level one week after surgery. Conclusion The operation of visual acuity early recovery, rapid astigmatism, no excessive damage to the corneal endothelium.
