The dioptric power of the cornea (spherical equivalent) was studied in 60 eyes operated on for penetrating keratoplasty. In order to determine the possible influence of (1) the underlying pathology, (2) the presence of neovascularisation, or (3) the size of the graft the sample was divided into four groups, with the following results: group A (keratoconus, same-sized graft) = 42.25 D; group B (keratoconus, oversized graft) = 45.16 D; group C (keratopathy with minimal or no vascularisation) = 45.34 D; group D (keratopathy with significant vascularisation) = 45.36 D. The results showed that donor-receptor disparity is the main factor determining the outcome of the postoperative corneal spherical power. There was no demonstrable influence from underlying pathology or the presence of vessels in the receptor cornea.
对60只接受穿透性角膜移植手术的眼睛的角膜屈光力(等效球镜)进行了研究。为了确定(1)潜在病理状况、(2)新生血管的存在或(3)移植物大小的可能影响,将样本分为四组,结果如下:A组(圆锥角膜,大小相同的移植物)=42.25屈光度;B组(圆锥角膜,过大的移植物)=45.16屈光度;C组(血管化程度极低或无血管化的角膜病变)=45.34屈光度;D组(血管化程度显著的角膜病变)=45.36屈光度。结果表明,供体-受体差异是决定术后角膜球镜屈光力结果的主要因素。受体角膜的潜在病理状况或血管的存在没有明显影响。
