Forty cases of keratoconus were surgically treated with epikeratoplasty. The surgical technique is aimed at reducing the degree of high irregular myopic astigmatism of keratoconus and providing the ectatic cornea with a permanent mechanical support. Nearly all patients showed a satisfactory improvement in uncorrected and best corrected visual acuity. This reduction of preoperative astigmatism and spherical equivalent with a regularization of the corneal surface permitted the fitting of contact lenses for daily wear in patients who were preoperatively intolerant of them.
40例圆锥角膜患者接受了表层角膜镜片术治疗。手术技术旨在降低圆锥角膜高度不规则近视散光的度数，并为扩张的角膜提供永久性机械支撑。几乎所有患者的未矫正视力和最佳矫正视力均有令人满意的改善。术前散光和等效球镜度的降低以及角膜表面的规则化，使得术前无法耐受的患者能够佩戴日戴型隐形眼镜。
