方法：对角膜深层异物取出术后患者46例46眼，随机分成戴镜组和对照组各23例23眼，两组均实施角膜深层异物取出术，比较两组患者术后1、3、7d的眼部疼痛程度及术后7d角膜上皮愈合情况。

结果：术后1、3、7d两组患者眼部疼痛程度评分：戴镜组分别为0.44±0.26、0.26±0.14、0.12±0.08分，对照组分别为1.26 ±0.44、1.02±0.38、0.68±0.26分，两组同一时段的眼部疼痛程度差异有统计学意义(P<0.05)； 术后7d两组患者角膜上皮缺损情况：戴镜组角膜上皮完全修复21眼(91%)，对照组上皮完全修复14眼(61%)，差异有统计学意义(P<0.05)。

结论：配戴绷带型角膜接触镜能有效缓解角膜深层异物取出术后患者的眼部刺激症状，能加速术后角膜创面的修复。

METHODS: Forty-six patients(46 eyes)with deep corneal foreignbody removal were divided into two groups(23 patients for each). Both groups received deep corneal foreignbody removal. Patients of group 1 wore bandage contact lenses after the surgery,while patients of group 2 did not receive any further treatment after the surgery. The differences in eye irritation( at 1,3 and 7d)and corneal epithelial healing(at 7d)between the two groups were observed.

RESULTS: Mean pain scores were significantly lower in group 1(0.44±0.26, 0.26±0.14, 0.12±0.08)than in group 2(1.26±0.44, 1.02±0.38, 0.68±0.26)at 1, 3 and 7d after the surgery(P<0.05). The rate of completely corneal epithelial healing at 7d were significantly higher in group 1(21 eyes, 91%)than in group 2(14 eyes,61%)(P<0.05).

CONCLUSION: Bandage contact lenses will accelerate the recovery of corneal wounds,improve the healthcare efficiency and effectively alleviate eye irritation.
