Since October 1977, the authors have attempted 32 keratophakias (refractive corneal surgery using an interlamellar homograft disc). Twenty-nine of these were primary and three secondary on aphakic eyes. These cases were divided into two series. In the first series, the dioptric correction was 28.5% less than the amount calculated to correct the aphakic error. In the second series, only 6.5% of the calculated dioptric power remained uncorrected. Keratophakia is an alternative to other modalities of secondary full-time correction of aphakia since the internal eye is not compromised by this secondary procedure as it is with a secondary intraocular implant. Further improvements in instrumentation techniques and mathematic programs will broaden the application of refractive keratoplasty techniques.
自1977年10月以来，作者尝试了32例角膜移植术（使用层间同种异体移植片进行的屈光性角膜手术）。其中29例为初次手术，3例为无晶状体眼的二次手术。这些病例分为两个系列。在第一个系列中，屈光矫正比计算出的矫正无晶状体眼误差的量少28.5%。在第二个系列中，仅6.5%的计算屈光度未得到矫正。角膜移植术是无晶状体眼二次全时矫正的其他方式的一种替代方法，因为这种二次手术不像二次眼内植入那样会损害眼内结构。仪器技术和数学程序的进一步改进将拓宽屈光性角膜成形术技术的应用范围。
