Extended-wear contact lenses (EWCL) were fitted successfully on 61 aphakic eyes with penetrating corneal grafts. In two- to 32-months follow-up there were 26 eyes that had varying amounts of superficial neovascularization of the grafts and one Staphylococcus epidermidis corneal graft ulcer. There were five homograft rejections, all occurring in severely diseased eyes. Variable vision and visual acuity less than that with hard contact lenses or aphakic spectacles were the most frequent problems. Both were due to the high corneal astigmatism present in many patients. The results indicate that EWCLs may be used safely by patients with penetrating corneal grafts and aphakia, particularly if there is no host corneal edema, scarring, or vascularization, if these are no synechias to the graft wound, and if the astigmatism is less than 3.0 diopters.
长期佩戴型隐形眼镜（EWCL）成功应用于61只接受穿透性角膜移植的无晶状体眼。在2至32个月的随访中，有26只眼出现了不同程度的移植片浅层新生血管形成，1只眼发生了表皮葡萄球菌性角膜移植溃疡。有5例同种异体移植排斥反应，均发生在病情严重的眼中。视力变化和视力低于硬性隐形眼镜或无晶状体眼镜是最常见的问题。这两者都是由于许多患者存在高度角膜散光所致。结果表明，穿透性角膜移植和无晶状体眼患者可安全使用EWCL，特别是在没有宿主角膜水肿、瘢痕形成或血管化，没有与移植伤口的粘连，且散光小于3.0屈光度的情况下。
