翼状胬肉术后角膜屈光状态稳定时间的临床观察

摘要

目的：观察翼状胬肉术后角膜屈光改变及屈光状态趋于稳定的时间。方法：随机选择翼状胬肉切除患者46例54眼，术前、术后3，7，14，30，90 d行角膜地形图检查，并进行统计分析。结果：翼状胬肉术后散光度较术前显著下降，术后3d与术后其他观察阶段相比，最陡径上的K值（ Ks值）、散光度差异有统计学意义（P＜0．05），术后7d及以后各观察阶段之间两两比较，Ks值、最平径上的K值（ Kf值）、散光度差异无统计学意义（P＞0．05）。结论：翼状胬肉术后7d角膜屈光状态基本稳定。%AIM: To observe the corneal refractive state stability time and changes of corneal refraction after excision of pterygium. METHODS:There were 46 cases ( 54 eyes ) , who had undergone excision of pterygium, randomly selected for corneal topography examination operated on the 3rd, 7th, 14th, 30th and 90th day after surgery.And statistic analysis was undertaken. RESULTS: Astigmatism after pterygium excision decreased significantly.Ks value, astigmatism in the 3 rd postoperative day compared with that in other observation phases showed differences of statistical significance ( P 0.05). CONCLUSION: Corneal refractive status is stable in 7 days afterpterygium excision surgery.
