We describe a case of corneal warpage caused by 14 years of rigid gas permeable (RGP) contact lens wear.
The patient was refit with daily wear high water content soft contact lenses.
After 6 months there were significant changes in both refraction and keratometry; computerized videokeratography showed that the corneal contour of both eyes had normalized.
Knowledge of contact lens induced corneal warpage is limited; it is therefore nor possible to follow a standard protocol for managing patients with this corneal deformation. In the case described, it was possible to reestablish a normal cornea without completely suspending contact lens wear by changing from RGP to hydrophilic material.
我们描述了一例因佩戴14年硬性透气性（RGP）隐形眼镜导致角膜变形的病例。
为该患者重新配镜，改为每日佩戴高含水量软性隐形眼镜。
6个月后，验光和角膜曲率测量均有显著变化；计算机化视频角膜地形图显示双眼角膜轮廓已恢复正常。
关于隐形眼镜引起角膜变形的知识有限；因此，对于患有这种角膜变形的患者，不可能遵循标准的治疗方案。在所描述的病例中，通过从RGP隐形眼镜更换为亲水性材料隐形眼镜，在不完全停止佩戴隐形眼镜的情况下，有可能使角膜恢复正常。
