摘要
目的探讨晶状体超声乳化吸出手术中切口位置对术后散光的影响。方法白内障80例(98眼)分为两大组,其中第一大组,又根据术前角膜地形图再分为AB两组:A组为顺规性散光组,作上方巩膜隧道切口;B组为逆规性散光组,作颞侧透明角膜切口,分别行超声乳化术加折叠式人工晶状体植入术;第二大组均作上方切口。术后观察3天,1月、3月和6月的角膜平均散光和裸眼视力情况。结果两大组在术后不同时间内角膜散光度之间有显著性差异。术后1月分别为(0.57±0.30)D和(1.20±0.59)D。结论根据患者术前角膜地形图,顺规性散光患者采用上方巩膜隧道切口,逆规性散光采用颞侧透明角膜切口。早期视力以颞侧透明角膜切口者恢复佳。
Objective To evaluate the effect of the incision positions in the operation of phacoemulsification on postoperative astigmatism and vision. Methods 80 patients(98 eyes) were chosen and divided into A and B (2 groups) based on the pre-operative axis of steep meridion. The superior scleral tunnel incision was recommended in the case with rule astigmatism (Group A) and the temporal clear corneal incision was preferred in the case against rule astigmatism(Group B).Foldable lens was implanted after the phacoemulsification. Observe and analyze the condition of the post-operative astigmatism and the uncorrected visual acuity (UCVA) after 3 days, 1 month, 3 months and 6 months. Results There was obvious difference in the astigmatism between the 2 groups after the phacoemulsification. The post-operative astigmatisms in different time were (0.57±0.30)D and (1.20±0.59)D after 1 month. Conclusion According to pre-operative axis of steep meridian, the superior scleral tunnel incision is recommended to the patients in Group A and the temporal clear corneal incision is recommended to the patients in Group B. The temporal clear corneal incision is better than the superior scleral tunnel incision in restoring the early-stage vision of the patients.
