目的探讨角膜穿孔伤后角膜散光与角膜伤口的大小、形态、部位及手术处理等因素的关系。方法用角膜曲率计测量139眼角膜穿孔伤后1天～1年角膜曲率的变化。结果自闭小瘢痕比间断缝合的小瘢痕散光小；相似长度的瘢痕，伤及角膜缘者散光明显，不规则散光多见；连续缝合比间断缝合术后散光小，两者拆线后散光都有不同程度的减少。结论采用连续缝合的方式处理伤口，术后及早拆线是减少术后散光的可取方法。
Objective To investigate the relationship between corneal astigmatism and corneal wound size, shape, location and surgical treatment after corneal perforation injury. Methods The change of corneal curvature was measured by corneal curvature meter in 1 to 1 year after corneal perforation in 139 eyes. Results Small scar with autismuctuated scar had less astigmatism than small scar with intermittent suture. Scar with similar length and corneal margin had obvious astigmatism and irregular astigmatism. Continuous astigmatism was less than astigmatism after interrupted suturing, both astigmatism There are different degrees of reduction. Conclusion Continuous suture treatment of wounds, postoperative early stitches is to reduce postoperative astigmatism desirable way.
