Since March 1986, the authors studied the simplified corneal cryopreservation technique with their "QL Bio-Freezer". After successful animal experiments, 34 patients (35 eyes) were performed penetrating keratoplasty with human cadaver corneas cryopreserved 9 to 473 days, averaging 108 days. After following-ups of 1 1/2 to 28 months, 22 of the corneal grafts remained clear, 6 semitransparent, and 7 cloudy. A total of 25 eyes had their visual acuity improved significantly. The results show that the cornea cryopreservation technique with the simplified "two-step" method is a noteworthy clinical practice.
自1986年3月起，作者们使用他们的“QL生物冷冻仪”研究了简化的角膜冷冻保存技术。在动物实验成功后，对34例患者（35只眼）进行了穿透性角膜移植术，所用的人尸体角膜冷冻保存了9至473天，平均108天。经过1个半月至28个月的随访，22只角膜移植片保持透明，6只半透明，7只混浊。共有25只眼的视力有显著提高。结果表明，采用简化“两步法”的角膜冷冻保存技术是一项值得关注的临床实践。
