Results of the author's first 15 cases of epikeratophakia for keratoconus are presented. All patients were intolerant of contact lens correction and could not achieve satisfactory acuity with spectacle correction due to corneal ectasia and irregular astigmatism. The average follow-up was 13 months. Seventy-three per cent of eyes treated had a pre-operative spectacle acuity of 6/60 or worse. One eye had a preexisting amblyopia that limited final acuity, but every other eye achieved a post-operative spectacle acuity of 6/12 or better and 50% achieved 6/6. One eye had 11 dioptres of post-operative astigmatism and required penetrating keratoplasty; the remaining eyes had an average astigmatism of 1.9 dioptres. Epikeratophakia appears to be a safe alternative to penetrating keratoplasty in selected cases.
本文介绍了作者对15例圆锥角膜患者行表层角膜镜片术的结果。所有患者均不能耐受角膜接触镜矫正，且由于角膜扩张和不规则散光，戴眼镜矫正也无法获得满意的视力。平均随访时间为13个月。接受治疗的患眼中，73%术前戴眼镜视力为6/60或更差。有一只眼术前存在弱视，限制了最终视力，但其他每只眼术后戴眼镜视力均达到6/12或更好，50%的患眼达到6/6。有一只眼术后散光达11屈光度，需要行穿透性角膜移植术；其余患眼平均散光为1.9屈光度。在特定病例中，表层角膜镜片术似乎是穿透性角膜移植术的一种安全替代方法。
