【摘要】：目的探讨散光陡峭轴切口在白内障超声乳化多焦点人工晶状体植入术中的应用效果。方法将28例(35眼)白内障患者随机分成两组,A组14例16眼,采用11点钟位透明角膜3.0 mm切口;B组14例19眼,在散光陡峭轴方位行透明角膜3.0 mm切口。所有患者均行超声乳化+人工晶状体植入术,术中植入多焦点人工晶状体。于术后1周、1个月、3个月观察患者角膜散光及裸眼远、近视力情况。结果 A组患者术后1周、1个月、3个月裸眼远视力分别为0.62±0.20、0.71±0.62、0.75±0.20,近视力分别为0.49±0.18、0.51±0.20、0.62±0.20;B组各时间点裸眼远视力分别为0.84±0.52、0.86±0.22、0.91±0.42,近视力分别为0.57±0.26、0.61±0.22、0.69±0.18,B组各时间点均好于A组,差异均有统计学意义(均为P0.05)。A组患者术后1个月、3个月时散光分别为(1.13±0.64)D和(1.03±0.34)D,B组分别为(0.89±0.40)D、(0.56±0.38)D,B组角膜散光小于A组,差异均有统计学意义(均为P0.05)。结论于散光陡峭轴行角膜切口可以降低白内障术后的角膜散光,提高多焦点人工晶状体植入术后的远、近视力。
[Abstract]:Objective to investigate the effect of steep axis astigmatism incision in phacoemulsification and intraocular lens implantation. Methods Twenty-eight patients (35 eyes) with cataract were randomly divided into two groups: group A (14 cases, 16 eyes) and group B (14 cases, 19 eyes) underwent transparent cornea 3. 0 mm incision in steep axis of astigmatism. All patients underwent phacoemulsification and intraocular lens implantation. Corneal astigmatism and distant and near visual acuity were observed 1 week, 1 month and 3 months after operation. Results the distance visual acuity of group A was 0.62 卤0.20 卤0.62 卤0.62 卤0.62 卤0.62 卤0.75 卤0.20 at 1 week, 1 month and 3 months after operation, and the near visual acuity was 0.49 卤0.18 卤0.51 卤0.20 卤0.62 卤0.20 respectively. The distance visual acuity of group B was 0.84 卤0.52 ~ 0.86 卤0.22 ~ 0.91 卤0.42, and the near visual acuity of group B was 0.57 卤0.26 ~ 0.61 卤0.22 ~ 0.69 卤0.18, respectively, which was better than that of group A at each time point. The difference was statistically significant (P0.05) in). A group (1.13 卤0.64) D at 3 months and (0.89 卤0.40) D, () 0.56 卤0.38 D in group B (P 0.05). The corneal astigmatism in group B was less than that in group A, and the difference was statistically significant (P0.05). Conclusion Corneal incision on the steep axis of astigmatism can reduce corneal astigmatism and improve the distant and near visual acuity after multi-focus intraocular lens implantation.
