A prospective randomly controlled trial of the effectiveness of pressure patching in the treatment of epithelial defects after keratoplasty in 41 patients (19 in the patched group and 22 in the unpatched group) showed no significant differences in healing between the two groups (P less than .25 to P less than .49 on postoperative days 1 to 6). The mean time needed for complete healing was 2.11 days in the patched group and 2.09 days in the unpatched group. Patients with bullous keratopathy preoperatively had larger initial defects (31.4 mm2) than those without (20.1 mm2) but the time needed for healing did not differ significantly (2.35 days vs 1.9 days; P less than .10).
一项针对41例角膜移植术后上皮缺损患者（19例接受加压包扎，22例未接受加压包扎）进行的前瞻性随机对照试验表明，两组间愈合情况无显著差异（术后第1至6天，P值介于小于0.25至小于0.49之间）。加压包扎组完全愈合所需的平均时间为2.11天，未加压包扎组为2.09天。术前患有大泡性角膜病变的患者初始缺损面积（31.4平方毫米）大于未患该病的患者（20.1平方毫米），但愈合所需时间差异无统计学意义（分别为2.35天和1.9天；P值小于0.10）。
