表面角膜镜片术(epikeratophakia)是1980年由Kaufman 基于角膜磨镶术(ke-ratomileusis)提出的一种新型屈光性手术。其手术方法是在去除上皮的患眼角膜表面,移植经切削加工成具有不同屈光度的角膜板层移植片,用以矫正患眼的屈光状态;将供体角膜切削成凸透镜用于治疗无晶体眼,切削成凹透镜用于治疗高度近视眼,切削成平镜用于治疗圆锥角膜。美国已在全国范围内协作进行临床研究,并将加工的角膜镜片长期保存,成为商品提供各地使用。作者于1985年设计了冷冻车床,
The epikeratophakia is a new type of refractive surgery based on Kaufman kerato-keratomileusis (ke-ratomileusis) in 1980. The surgical method is to remove the epithelial corneal surface of the cornea, transplanted into corneal lamellar grafts with different diopters, to correct the refractive state of the affected eye; the donor cornea is cut into a convex lens for the treatment of non-crystalline Eye, cut into a concave lens for the treatment of high myopia, cut into flat mirror for the treatment of keratoconus. The United States has collaborated on clinical research across the country and has long-term preservation of processed corneal lenses to provide products for use throughout the country.
