A short-term study of the physiologic response of the cornea to polymethyl methacrylate (PMMA) contact lenses and hard, gas-permeable contact lenses of different materials (polycon and Menicon 02), thicknesses, and fittings, was carried out on nine unadapted subjects using one eye as the experimental eye and the other as the control eye (no lens). Changes in corneal thickness were monitored at seven locations across the cornea using an electronic micropachymeter. It was found that gas-permeable lenses produced less corneal swelling than the PMMA lenses. However, lens thickness and the fit of the lens were still important control variables with these gas-permeable lenses. The thin gas-permeable lens produced less swelling than thicker lenses, and the flatter fitting gas-permeable lenses produced less swelling than the steeper fitting lenses. The swelling with all the hard lenses studied was confined primarily to the central 6 mm of the cornea.
对9名未适应隐形眼镜的受试者进行了一项短期研究，以一只眼睛作为实验眼，另一只眼睛作为对照眼（不戴隐形眼镜），研究角膜对聚甲基丙烯酸甲酯（PMMA）隐形眼镜以及不同材料（Polycon和目立康02）、厚度和适配度的硬性透气隐形眼镜的生理反应。使用电子显微厚度仪在角膜的七个位置监测角膜厚度的变化。结果发现，透气隐形眼镜比PMMA隐形眼镜引起的角膜肿胀更少。然而，对于这些透气隐形眼镜，镜片厚度和适配度仍是重要的控制变量。薄的透气隐形眼镜比厚的镜片引起的肿胀更少，适配较平的透气隐形眼镜比适配较陡的镜片引起的肿胀更少。所有研究的硬性隐形眼镜引起的肿胀主要局限于角膜中央6毫米范围内。
