翼状胬肉术后角膜屈光状态稳定时间的临床观察

Clinical observation of corneal refractive stability time after excision of pterygium

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3,7,14,30,90d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 3＇d, 7th, 14TM, 30TM and 90t day after surgery. And statistic analysis was undertaken. ~ RESULTS： Astigmatism after pterygium excision decreased significantly. Ks value, astigmatism in the 3＇a postoperative day compared with that in other observation phases showed differences of statistical significance （ P 〈 0. 05 ）. Ks value, Kf value, and astigmatism in the 7th days compared with that in other observation phases showed differences of no statistical significance （P〉0.05）. ~ CONCLUSION： Corneal refractive status is stable in 7 days afterpterygium excision surgery.
