Abstract

Penetrating keratoplasty was done in 104 cases with keratoconus. The donor material were preserved either as a whole eye in moist chamber at 4 degrees C, or as a corneoscleral segment in MK-medium at 4 degrees C, or in a tissue culture. The post-operative observation time varied between 6 months and 9 years. The visual acuity was found to be better than before surgery in 96%, unchanged in 3%, and worse in 1% of the cases. The average visual acuity was found to be after 6 months 0.25 +/- SD 0.2 and after 7 years 0.65 +/- SD 0.23. The post-operative spherical error of refraction was found to be -3.26 +/- SD 3.5 D, and the post-surgical astigmatism -2.6 +/- SD 1.9 D.

摘要

对104例圆锥角膜患者实施了穿透性角膜移植术。供体材料要么在4℃的湿盒中作为全眼球保存，要么在4℃的MK培养基中作为角膜巩膜段保存，要么在组织培养中保存。术后观察时间为6个月至9年。结果发现，96%的患者视力比手术前有所提高，3%的患者视力无变化，1%的患者视力下降。术后6个月平均视力为0.25±标准差0.2，术后7年为0.65±标准差0.23。术后屈光性球镜度数为-3.26±标准差3.5D，术后散光为-2.6±标准差1.9D。
