A combination formed by covering a soft contact lens on the cornea with either an oxygen-permeable or an impermeable hard lens offers some advantages over a soft lens or a hard lens alone. Several procedures can be used to fit such combinations to the eye. The amount of oxygen that is delivered to the cornea will depend strongly on the fit on the soft lens to the cornea and the fit of the hard lens to the soft lens; the amount of oxygen delivered by 4 different combinations is described here. The results show that the proper choice of lenses and fit will permit an adequate supply of oxygen to reach the cornea in daily wear.
通过将透氧或不透氧的硬性镜片覆盖在角膜上的软性隐形眼镜所形成的组合，相较于单独使用软性镜片或硬性镜片具有一些优势。有几种方法可用于将这种组合适配到眼睛上。输送到角膜的氧气量将很大程度上取决于软性镜片与角膜的适配度以及硬性镜片与软性镜片的适配度；此处描述了4种不同组合所输送的氧气量。结果表明，正确选择镜片和适配方式将能在日常佩戴中使足够的氧气供应到角膜。
