A pilot study was carried out in Pakistan to assess the feasibility of the use of lathed freeze-dried corneal tissue in the treatment of corneal scarring.
Six eyes underwent lamellar keratoplasty and were followed up for 18 months.
Visual improvement was obtained in every eye. In one eye, the procedure was complicated by delayed epithelialization of the graft, but in the remaining five patients, the grafts epithelialized rapidly.
The use of freeze-dried donor tissue simplifies storage and distribution of corneas and may offer the best hope of treatment in developing countries for patients with corneal scarring.
在巴基斯坦进行了一项试点研究，以评估使用车床冻干角膜组织治疗角膜瘢痕的可行性。
对6只眼睛进行了板层角膜移植术，并随访18个月。
每只眼睛的视力均有改善。其中一只眼睛手术出现移植片上皮化延迟的并发症，但其余5例患者的移植片上皮化迅速。
使用冻干供体组织简化了角膜的储存和分配，对于发展中国家角膜瘢痕患者而言可能提供了最佳治疗希望。
