Descemetocele or corneal perforation makes it difficult to perform penetrating keratoplasty (PKP). To circumvent this difficulty, a polymethylmethacrylate hard contact lens with a diameter of 4.0 mm was customized and applied to the cornea with tissue adhesive prior to PKP in three patients, one with corneal perforation and two with descemetoceles. The results showed that this modified method facilitated trephination during PKP without complications in all three patients, suggesting that it may be applicable to other similar clinical situations.
后弹力层膨出或角膜穿孔会使穿透性角膜移植术(PKP)难以实施。为克服这一困难,定制了直径为4.0毫米的聚甲基丙烯酸甲酯硬性接触镜,并在3例患者(1例角膜穿孔,2例后弹力层膨出)的PKP术前,用组织黏合剂将其应用于角膜。结果显示,这种改良方法在所有3例患者的PKP术中均便于环钻术操作且无并发症,提示其可能适用于其他类似临床情况。
