目的：观察绷带型角膜接触镜在滞留型铁质角膜异物取出术后的临床疗效。方法：对角膜深层异物取出术后患者 105 例 105 眼，随机分为戴镜组与对照组，两组均为滞留型角膜异物，实施角膜异物取出术，比较两组患者术后 1，3，7 d 的眼部疼痛程度及术后 7 d 角膜上皮愈合情况。结果：术后 1，3，7 d ，两组患者眼部疼痛程度评分差异有统计学意义（P<0.05）；术后 7 d 两组患者角膜上皮缺损情况差异有统计学意义（P<0.05）。无感染患者。结论：配戴绷带型角膜接触镜能有效缓解滞留型角膜异物取出术后患者的眼部刺激症状，加速术后角膜创面修复。
Objective: To investigate the effects of bandage contact lenses on corneal irritation and wound healing after the removal of delayed corneal iron foreign body. Methods: A total of 105 patients （105 eyes） with delayed removal of corneal iron foreign body were divided into two groups. Patients in both groups received the removal of corneal foreign body. Patients in group 1 wore bandage contact lenses after surgery, and their counterparts in group 2 did not receive any further treatment after surgery except eye drops. The differences in eye irritation （at 1, 3 and 7 d） and corneal epithelial healing （at 7 d） were observed between two groups. Results: The mean pain score was significantly lower in group 1 than that in group 2 at 1, 3 and 7 d after surgery （all P<0.05）. The rate of complete corneal epithelial healing at 7 d was significantly higher in group 1 than that in group 2 （P<0.05）. Conclusion: Bandage contact lenses can accelerate the recovery of corneal wounds, improve the healthcare efficiency and effectively alleviate eye irritation.
