【摘要】：目的比较前房维持器与黏弹剂在白内障超声乳化吸除术中对术后早期角膜的影响。方法将61眼年龄相关性白内障患者随机分成两组,A组29眼采用前房维持器下超声乳化,B组32眼采用黏弹剂维持前房下超声乳化。观察术前、术后1周和术后1个月的角膜内皮细胞密度以及角膜散光的改变。结果两组间术后不同时间角膜内皮细胞丢失率,A组术后1周22.61%、术后1个月27.14%,B组术后1周20.71%、术后1个月26.23%,术后1周及术后1个月两组角膜内皮细胞丢失率差异均无统计学意义(P0.05)。A组术后1周及术后1个月术源性散光分别为(0.79±0.43)D和(0.69±0.43)D,B组分别为(0.79±0.38)D和(0.73±0.36)D,术后1周及术后1个月两组之间术源性散光差异均无统计学意义(P0.05)。结论白内障超声乳化吸除手术中前房维持器持续维持前房并未加重角膜内皮细胞损伤及增加术源性散光,说明白内障超声乳化吸除术中使用前房维持器是安全有效的。
[Abstract]:Objective to compare the effect of anterior chamber maintainer and viscoelastic on early cornea after cataract phacoemulsification. Methods Sixty-one patients with age-related cataract were randomly divided into two groups: group A (n = 29) received anterior chamber phacoemulsification (n = 32) and group B (n = 32) treated with viscoelastic agent. The changes of corneal endothelial cell density and corneal astigmatism before, 1 week and 1 month after operation were observed. Results the rate of corneal endothelial cell loss in group A was 22.61 at different time after operation, 20.71 in group B and 20.71 in group B, and 26.23 in group B at 1 month after operation. There was no difference in the rate of loss of corneal endothelial cells between two groups at 1 week after operation and 1 month after operation. There was no difference in corneal endothelial cell loss rate between two groups at 1 week and 1 month after operation. The difference of postoperative astigmatism was (0.79 卤0.43) D and (0.69 卤0.43) D in group A and (0.79 卤0.38) D and (0.73 卤0.36) D in group A respectively. There was no significant difference between the two groups at 1 week and 1 month after operation (P0.05). Conclusion the continuous maintenance of anterior chamber during phacoemulsification does not aggravate the injury of corneal endothelial cells and increase the postoperative astigmatism, which indicates that the use of anterior chamber maintainer in phacoemulsification is safe and effective.
