在63名患者中进行了65次表面角膜镜片术;对31名患者的视力数据进行了4至30个月的随访。随访超过一年的患者显示稳定的角膜曲率读数。早期患者实现了70%的预测屈光矫正;近期患者实现了87%的预测屈光矫正，并改善了车削手术、组织处理和手术技术。视力随着时间的推移而提高。在手术后的任何给定时间，用硬接触透镜测量的视力优于用眼镜测量的视力;眼镜视力的下降可能是移植物表面不规则屈光的结果。接触透镜与眼镜之间的差距随时间而减小。许多患者术后视力优于术前视力，大多数患者的最终眼镜视力在术前视力的一行或两行内。
Sixty-five epikeratophakia procedures have been performed in 63 patients; visual acuity data have been tabulated on 31 patients with 4 to 30 months follow-up. Patients with more than a year of follow-up showed stable keratometry readings. Early patients achieved 70% of the predicted dioptric correction; more recent patients have achieved 87% with improvements in the lathing procedure, tissue handling, and surgical technique. Visual acuities improve with time. At any given time after surgery, acuities measured with a hard contact lens are better than those measured with spectacles; the decrease in spectacle acuity is probably a result of irregular refraction at the graft surface. The gap between contact lens and spectacle acuity decreases with time. A number of patients achieve postoperative visual acuities better than their preoperative acuities, and most achieve final spectacle acuities within a line or two of their preoperative acuities.
