Abstract： 目的:探讨小牛血去蛋白提取物在Epi-lasik术中应用的安全性和临床疗效.方法:观察在本院行Epi-lasik手术的患者112眼,所有病例随机分为A,B两组:A组(小牛血去蛋白提取物组)58眼,B组(重组人表皮生长因子衍生物组)54眼,两组分别在Epi-lasik术后,立即用小牛血去蛋白提取物和重组人表皮生长因子衍生物眼药水,并观察患者术后刺激症状、术后角膜上皮瓣生长情况、术后视力及达到术前最佳矫正视力的时间、haze等情况,随访6~12mo.结果:A组的角膜上皮瓣生长情况要好于B组,两组间的差异有统计学意义(P<0.05).术后1mo检查,A组有45眼(77.6%)达到术前最佳矫正视力,B组有32眼(59.3%),两组差异有统计学意义(P<0.05).在达到术前最佳矫正视力的时间上,A组的大部分患者在术后1wk以内达到,而B组的患者多在术后2wk以后达到,两组差异有统计学意义(P<0.05).两组在对术后haze的影响方面没有显著性差异(P>0.05).结论:在Epi-lasik手术中应用小牛血去蛋白提取物,可以减轻角膜上皮瓣的水肿,缩短术后视力恢复的时间,改善干眼症状,安全有效,具有良好的应用前景.
