Generally in keratoconus the corneal apex displacement is inferior in position and bilateral in expression. Two young male keratoconic subjects enrolled in the Dundee University Scottish Keratoconus Study (DUSKS) demonstrated with corneal topography the presence of unilateral superior keratoconus. Successful visual rehabilitation of a superior cone with contact lens fitting represents a particular challenge to the contact lens practitioner. This report discusses the management of two such cases.
一般来说，圆锥角膜的角膜顶点移位位置靠下且双侧出现。两名参与邓迪大学苏格兰圆锥角膜研究（DUSKS）的年轻男性圆锥角膜患者，通过角膜地形图显示存在单侧上方圆锥角膜。使用角膜接触镜矫正上方圆锥角膜以成功实现视力康复，对角膜接触镜从业者来说是一项特殊挑战。本报告讨论了两例此类病例的处理。
