The authors present the results of 11 keratoplasties in cases of keratoconus, comparing the visual acuity and the ocular refraction before and after the operation (ophtalmometry, objective and subjective refractometry). The statistical data indicate a meaningful flattening of the corneal curvature (12.84 dpt average) and a mean reduction of the myopia for 8.227 dpt. In fact, the basic regular astigmatism of the cornea had not been altered. The mean visual acuity was 0.68 (with an improvement of 0.495). No further damage of acuity had been observed. After 10 to 69 months a medical checkup revealed transparent grafts in five cases; four presented small maculae; one, thin folds of Descemet's membrane. Based on the authors' experience and on the literature, the paper recommends lamellar keratoplasty in cases of keratoconus, the surgeon must choose the appropriate moment in the course of the development of this disease.
作者介绍了11例圆锥角膜角膜移植手术的结果，比较了手术前后的视力和眼屈光情况（角膜曲率计检查、客观和主观验光）。统计数据表明角膜曲率有显著变平（平均12.84屈光度），近视平均降低8.227屈光度。实际上，角膜的基本规则散光未改变。平均视力为0.68（提高了0.495）。未观察到视力进一步受损。术后10至69个月的医学检查显示，5例移植片透明；4例有小斑点；1例有Descemet膜薄皱襞。基于作者的经验和文献，本文建议在圆锥角膜病例中采用板层角膜移植术，外科医生必须在该疾病发展过程中选择合适的时机。
