目的：通过博士伦PureVision纯视角膜接触镜在眼科的应用，观察绷带镜在持续性角膜上皮缺损中的应用及临床效果，评估绷带镜在眼表疾病中的治疗价值及意义。

方法：非随机选取持续性角膜上皮缺损患者30例38眼， 配戴绷带镜3d～3mo，观察配戴前后各时段角膜刺激症状、角膜上皮愈合情况、视力及不良反应情况。

结果：所选患者30例38眼中完全缓解23眼(61%)，部分缓解11眼(29%)，有效率 89%。促进角膜上皮愈合：完全愈合11眼(29%)，部分愈合 21眼(55%)，有效率 84.2%； 视力提高22眼，有效率58%。

结论：绷带镜能有效缓解角膜上皮缺损引起的疼痛，保护角膜，维持局部湿润度，加速持续性角膜上皮病变的愈合，缩短病程，安全、有效，可广泛应用于临床，在基层医院推广。

AIM:To apply the PureVision Bandage contact lens in ophthalmology, observe the clinical effects and bandage lens used in persistent corneal epithelial defect, and assess the evaluation and significance of bandage lens in ocular surface disease therapeutic.

METHODS: Thirty patients(38 eyes)with persistent corneal epithelial defects wearing a bandage lens from 3d to 3mo were non-randomly selected. The results of corneal irritation symptoms, visual acuity, corneal epithelial healing and adverse circumstances during each period of before and after wearing bandage lens were observed.

RESULTS:For all 30 cases(38 eyes), complete remission(23 eyes, 61%), partial remission(11 eyes, 29%), effective rate 89%. Promote healing of corneal epithelium: healed completely(11 eyes, 29%), partially healed(21 eyes, 55%), effective rate 84.2%. The visual acuity was improved in 22 eyes, efficiency 58%.

CONCLUSION:Wearing bandage lens can effectively relieve the pain caused by corneal epithelial defect, protect corneal, maintain the local moisture, accelerate healing of persistent corneal epithelial lesions, and shorten the course of disease. It is a safe and effective method, and it can be widely used in clinical application and promoted in basic level hospital.
