目的探讨前房注气联合低温保存眼球行治疗性角膜移植的可行性及疗效评价。方法采用新鲜供体眼球抽取房水并注入惰性气体后置-80℃低温冰箱长期保存。作为供体共行治疗性角膜移植55例(58眼),观察治疗效果。结果行板层角膜移植(LK)25例(28眼),穿透角膜移植(PK)30例(30眼),术后平均随访10 2个月,一次手术成功47眼(81.04%),手术失败11眼(18.96%),视力提高33例(34眼)。结论采用此方法行治疗性LK可起到治疗和增视的双重目的,PK可去除病灶、控制炎症、封闭穿孔、保存眼球,为再次增视性手术提供条件。
Objective To investigate the feasibility and therapeutic effect of anterior chamber gas injection combined with cryopreservation of eyeballs on therapeutic keratoplasty. Methods A fresh donor eyeball was used to draw aqueous humor and filled with inert gas and stored at -80 ℃ for a long time. As a donor of therapeutic keratoplasty in 55 cases (58 eyes), to observe the therapeutic effect. Results Twenty - five patients (28 eyes) underwent lamellar keratoplasty (KK) and 30 eyes (30 eyes) through penetrating keratoplasty. The average follow - up time was 102 months. One operation succeeded in 47 eyes (81.04%), Failure in 11 eyes (18.96%), visual acuity improved in 33 cases (34 eyes). Conclusion This method of treatment of LK can play a dual purpose of treatment and increased vision, PK can remove the lesion, inflammation control, closed perforation, save the eye, to provide the conditions for re-visualization surgery.
