摘要
目的 观察白内障超声乳化术合并人工晶状体植入术后角膜散光状态的变化 ,评价切口缝合与对角膜散光的影响。方法 将 1 2 7例 ( 1 3 5只眼 )老年性白内障患者按照切口缝合与否分为A、B两组 ,采用巩膜隧道切口白内障超声乳化术合并人工晶状体植入术。术后定期观察角膜散光和视力的变化情况。结果 术后 1年A、B两组平均手术性角膜散光度分别为 0 76D± 0 54D和 1 84D± 0 63D ,差异有显著性 (P <0 0 5) ;裸眼视力≥ 0 5者分别为 89 92 %和65 55% ,两组比较差异有显著性 (P <0 0 5)。结论 白内障超声乳化术合并人工状体植入术巩膜隧道切口未缝合者术后会产生较明显而持久的逆规性角膜散光。常规缝合切口会明显减少术后角膜散光。
OBJECTIVE To investigate the changes of corneal astigmatism following phacoemulsification with unfold intraocular lens implantation and evaluate the influence of suture or without suture for a scleral tunnel incision on corneal astigmatism.METHODS Phacoemulsification with unfold intraocular lens implantation was performed on 127 cases(135 eyes)for a scleral tunnel incision and the patients were divided into group A and group B by suture of incision or without incision. The changes of corneal astigmatism before and after operation were compared between group A and B.RESULTS One year after the operation an average diopter of surgical astigmatism was 0.76D±0.54D in the group A and 1.84D±0.63D in the group B respectively. There was significant difference statistically between two groups (P<0.05). The visual acuity without correction≥0.5 was 89.92% and 65.55% in group A and Respectively. There was significant difference, statistically (P<0.05) between two groups. CONCLUSIONS There was evident and permanence astigmatism against rule after phacoemulsification with unfold intraocular lens implantation without suture for a scleral tunnel incision. It could reduced corneal astigmatism to suture conventional incision postoperatively.
