作者采用中厚游离皮肤植片手术治疗2例(3眼)角膜巩膜缺损者,获得了令人满意的结果。第1例(17岁,男性),双眼严重碱性烧伤部分眼睑受累。尽管积极采用药物治疗,伤后7周,右眼下部仍然出现了小的穿孔,伴有虹膜脱出。因为严重的局部缺血和角膜溶解,作者选用中厚游离皮肤植片遮盖穿孔,以便防止角膜进一步溶解。用Brown氏电动切皮机从大腿上取皮,厚度为0.012～0.015英寸。将皮片切成每边长8mm的小块,立即缝合于患处。皮片上切一些小孔,以防积液。围绕角巩膜缘作360度结膜环形切开,因为 The authors treated 2 cases (3 eyes) of corneal scleral defect by free skin graft surgery and obtained satisfactory results. The first case (17 years old, male), partial eyelid involvement of severe alkali burns. Despite aggressive drug treatment, a small perforation occurred in the lower part of the right eye with an iris prolapse, seven weeks after injury. Due to severe ischemia and corneal lysis, the authors selected medium-thick free skin grafts to cover the perforations to prevent further corneal lysis. Take the skin from the thigh with Brown’s electric skinning machine, and have a thickness of 0.012 to 0.015 inches. The skin cut into small pieces of 8mm on each side, immediately sutured in the affected area. Cut some holes on the skin to prevent fluid. Around the corneal limbus for 360 degree conjunctival ring incision, because
