To report and discuss cases of lamellar keratoplasty using corneas obtained during previous penetrating keratoplasty in keratoconus eyes.
Corneal buttons were obtained from 7 keratoconus patients and stored in a preserving solution for 7-60 days (average, 32.4 days) before use. The recipient eyes comprised recurrent pterygium 3 eyes, primary pterygium 1 eye, pseudopterygium 1 eye, corneal perforation with iris prolapse due to fungal corneal ulcer 1 eye, and limbal dermoid 1 eye.
The recipient eyes ran favorable courses in general. Graft rejection developed in 2 eyes and was successfully treated with topical and systemic corticosteroid.
Preserved corneas from keratoconus eyes were found useful in therapeutic lamellar keratoplasty. By this procedure, the current inadequate supply of donor corneas in eye banks in Japan can be augmented.
报告并讨论在圆锥角膜眼中使用先前穿透性角膜移植术中获取的角膜进行板层角膜移植的病例。
从7例圆锥角膜患者获取角膜植片，在使用前保存在保存液中7 - 60天（平均32.4天）。接受者眼睛包括复发性翼状胬肉3只眼、原发性翼状胬肉1只眼、假性翼状胬肉1只眼、真菌性角膜溃疡导致角膜穿孔伴虹膜脱出1只眼和角膜缘皮样瘤1只眼。
接受者眼睛总体病程良好。2只眼发生移植排斥反应，经局部和全身使用皮质类固醇成功治疗。
发现圆锥角膜眼保存的角膜在治疗性板层角膜移植中有用。通过此方法，可增加日本眼库目前供体角膜供应不足的情况。
