【摘要】：目的探讨Phaco drill术式对角膜内皮的影响。方法超声乳化手术治疗白内障165眼。乳化针头斜面向上完成晶状体核去除102眼中,超声时间在60s内83眼(A组),超声时间超过60s19眼(B组);乳化针头斜面向下完成晶状体核去除(Phaco drill术式)63眼中,超声时间在60s内49眼(C组),超声时间超过60s14眼(D组)。检测术前、术后1周角膜内皮细胞计数和角膜内皮正常六边形细胞比率变化。结果 A、B、C、D组术后1周患眼角膜内皮细胞计数较术前分别减少(12.3±5.7)%、(21.7±4.1)%、(9.1±3.9)%和(12.2±3.5)%,B组减少比率显著高于D组(P0.01)。A、B、C、D组术后1周患眼角膜内皮正常六边形细胞比率分别较术前下降(14.1±4.4)%、(22.3±3.5)%、(10.3±4.2)%、(14.7±2.9)%,B组下降比率显著高于D组(P0.01)。结论在超声乳化时间较长的情况下,Phaco drill术式对角膜内皮细胞损伤较少。
[Abstract]:Objective to investigate the effect of Phaco drill procedure on corneal endothelium. Methods #number0# eyes of cataract were treated by phacoemulsification. The ultrasonic time was over 60 s in group A (83 eyes) and more than 60 s (19 eyes) in group B. The phaco drill procedure was performed in 63 eyes. The ultrasonic time was within 60 s in 49 eyes of group C and more than 60 s of 14 eyes in group D. Results the number of corneal endothelial cells and the ratio of normal hexagonal cells of corneal endothelium were decreased by 12.3 卤5. 7% and 12.2 卤3. 5% respectively at 1 week after operation in group A and B were significantly higher than those in group D (P 0. 01, P 0. 01, P 0. 01, P 0. 01, P 0. 01, P 0. 01, P 0. 01, P 0. 01, P 0. 01, P < 0. 01, P < 0. 01, P < 0. 01, P < 0. 01, P < 0. 01, P < 0. 01, P < 0. 01, P 0. 01). The ratio of normal hexagonal cells of corneal endothelium in group B was significantly higher than that in group D (14.7 卤2.9%) 1 week after phacoemulsification. Conclusion under the condition of phacoemulsification for a long time, the injury of corneal endothelial cells in group B is less than that in group B.
