在106例成功配戴透镜4 - 8年（中位数，4.94年）的患者中评价了长期配戴接触透镜（perfilcon A [Permalens]）治疗近视的长期效果。在207只眼睛中，95%的视力为6/12（20/40）或更好。角膜新生血管，当遇到（8.7%），是轻度的，并没有降低视力。无感染性角膜溃疡或瘢痕形成或使用透镜导致永久性视力丧失的病例。在选定的患者中，使用长戴型镜片似乎是一种合理的近视光学矫正形式，值得进一步研究。这些透镜的使用进行了讨论，作为一种替代的放射状角膜切开术的实验程序。
The long-term effects of an extended-wear contact lens (perfilcon A [Permalens]) for myopia were evaluated in 106 patients who had successfully worn the lens for four to eight years (median, 4.94 years). Visual acuity was 6/12 (20/40) or better in 95% of the 207 eyes fitted. Corneal neovascularization, when encountered (8.7%), was mild and did not reduce visual acuity. There were no cases of infectious corneal ulcer or scarring or of permanent visual loss from use of the lens. In selected patients, use of extended-wear lenses seems to be a reasonable form of optical correction of myopia, and they deserve further study. The use of these lenses is discussed as an alternative to the experimental procedure of radial keratotomy.
