以板层角膜移植术矫正圆锥角膜已被推荐为一种安全的、无损害的眼外手术。应用新的显微技术和不带内皮的全厚角膜,使该手术更为简易。同时,由后弹力膜作为层间光学界面,从而获得更好的视力。本文报导52例圆锥角膜手术的长期疗效,并详细描述手术操作过程。选择视力不能以接触镜矫正,准备行穿透性角膜移植或热性角膜成形术(thermokeratop-lasty)的进行性圆锥角膜共52只眼。随访期为6—48个月。术前检查包括光学诊断、绘制圆锥的部位和
Corneal keratoplasty with lamellar keratoplasty has been recommended as a safe, non-invasive extra-ocular procedure. The use of new microscopy and non-endothelial full-thickness corneas make the procedure much easier. At the same time, by the post-stretch film as an interlayer optical interface, resulting in better vision. This article reports the long-term efficacy of 52 cases of keratoconus surgery and describes in detail the surgical procedure. A total of 52 eyes of progressive keratoconus with penetrating keratoplasty or thermokeratop-lasty were selected for correction of visual acuity. Follow-up period is 6-48 months. Preoperative examination includes optical diagnosis, drawing the cone of the site and
