目的评价聚乙二醇滴眼液滴眼液在准分子激光上皮下角膜磨镶术(LASEK)中的临床应用价值。方法观察行LASEK术患者45例(90只眼),屈光度范围(-4.68±2.30)D(-1.75～-6.50 D),随机分为聚乙二醇滴眼液组(试验组)和对照组,对两组术后角膜刺激症状、上皮愈合情况进行对比观察和统计学分析。结果试验组术后第1、3、5天角膜刺激症状明显轻于对照组(P<0.05),上皮愈合速度较对照组更快(P<0.05)。结论在LASEK术中合理使用聚乙二醇滴眼液,可明显减轻术后患者角膜刺激症状,促进角膜上皮的更快愈合。
Objective To evaluate the clinical value of polyethylene glycol eye drops in excimer laser subepithelial keratomileusis (LASEK). Methods 45 patients (90 eyes) underwent LASEK and the range of refraction (-4.68 ± 2.30) D (-1.75 ~ -6.50 D) were randomly divided into two groups: pegylated eye drops group (experimental group) and control group , The two groups of postoperative corneal irritation, epithelial healing comparison and statistical analysis. Results The corneal irritation symptoms in the experimental group were significantly lower than those in the control group on the 1st, 3rd and 5th postoperative day (P <0.05). The epithelial healing rate of the experimental group was faster than that of the control group (P <0.05). Conclusion The rational use of polyethylene glycol eye drops in LASEK surgery can significantly reduce postoperative corneal irritation and promote faster corneal epithelial healing.
