In vitreoretinal disorders complicated by corneal opacity, a temporary keratoprosthesis device is placed into a trephined opening in the cornea to provide a clear stable view which permits the performance of pars plana vitrectomy and immediately following the vitrectomy, the keratoprosthesis is replaced by a corneal graft. Using this technique, we have saved blind eyes with corneal and vitreoretinal disorders in one surgical procedure, being a new approach for rehabilitation of eye sight. Since 1990, the operation has been performed on 10 patients of whom 9 obtained satisfactory results. They were the patients who had been impossible to be saved by other methods and had been abandoned. The patient with the best result had been followed for 15 months and his visual acuity achieved and maintained 0.3. In six cases, the operation was combined with multiple procedures in the vitreous, such as gas fluid exchange, internal drainage of subretinal fluid, injection of silicone oil, etc. to facilitate the reattachment of the complicated retinal detachment.
在伴有角膜混浊的玻璃体视网膜疾病中，将一种临时性人工角膜装置置入角膜的环钻开口处，以提供清晰稳定的视野，从而能够进行玻璃体切除术。在玻璃体切除术后，立即用角膜移植片替换人工角膜。通过这种技术，我们在一次外科手术中挽救了患有角膜和玻璃体视网膜疾病的盲眼，这是一种恢复视力的新方法。自1990年以来，已对10例患者实施了该手术，其中9例取得了满意的效果。这些患者是其他方法无法挽救且已被放弃治疗的患者。效果最佳的患者已随访15个月，其视力达到并维持在0.3。在6例手术中，该手术与玻璃体的多种操作相结合，如气液交换、视网膜下液内引流、硅油注射等，以促进复杂视网膜脱离的复位。
