目的 评价亲水性软性角膜接触镜对PRK术后角膜上皮愈合的影响。方法 对 91例低中度近视病例分为戴镜组 (Ⅰ组 )和包眼组 (Ⅱ组 ) ,观察PRK术后角膜上皮愈合情况、角膜刺激症状及视力。结果 角膜上皮愈合时间 :Ⅰ组平均为 2 37± 0 73天 ,Ⅱ组为 3 96± 1 0 5天 (P <0 .0 5 ) ;48小时内愈合者分别为 92 5 5 %和 80 5 9%。角膜刺激症 :+～ + +者Ⅰ组和Ⅱ组分别为 6 5 96 %和 17 6 5 % ,≥ + + +者分别为 33 86 %和 72 35 %。术后 7天裸眼视力 :≥ 0 .5者两组分别为 98 94%和 98 82 % ,但≥ 1 0者分别为 5 2 13%和 9 41%。结论 PRK术后配戴亲水性软性角膜接触镜可促进角膜上皮愈合和视力恢复
Objective To evaluate the effect of hydrophilic soft contact lens on corneal epithelial healing after PRK. Methods Ninety-one cases of low and moderate myopia were divided into wearing group (group Ⅰ) and enophthalmic group (group Ⅱ). The corneal epithelial healing, corneal irritation and visual acuity were observed after PRK. Results The healing time of corneal epithelium was 2.337 ± 0.73 days in group Ⅰ, 396 ± 105 days in group Ⅱ (92.5%) and 805 (48.5%) in 48 hours 9%. Corneal irritation: 65 + 96% and 1765% respectively in group Ⅰ and group Ⅱ + + +, and 33 86% and 72 35% in group + + + +. Visual acuity of the naked eye on day 7 postoperatively: ≥ 0.5 was 98.94% and 98.82% for the two groups, but 52.0% and 91.4% for those with ≥10. Conclusion PRK postoperative soft hydrophilic contact lens wear can promote corneal epithelial healing and visual acuity
