We evaluated the use of a highly gas-permeable, fluid-filled scleral lens for patients with diseased corneas for whom conventional contact lens strategies failed. Fifteen patients were successfully fit with individually fabricated scleral lenses. Significant corneal hypoxia, which limited the use of previous polymethylmethacrylate scleral lenses, was not encountered. Preliminary results suggest that a gas-permeable scleral lens may offer therapeutic as well as visual benefit to some patients with severe corneal disease.
我们评估了一种高度透气、充满液体的巩膜镜对角膜病变患者的使用情况，这些患者使用传统隐形眼镜策略均告失败。15名患者成功佩戴了定制的巩膜镜。未出现显著的角膜缺氧情况，而这一情况曾限制了先前聚甲基丙烯酸甲酯巩膜镜的使用。初步结果表明，透气巩膜镜可能会给一些严重角膜疾病患者带来治疗和视觉上的益处。
