Mistaken diagnosis of keratoconus because of corneal warpage induced by hydrogel lens wear.

Purpose: We report a case of corneal warpage secondary to hydrogel lens wear that was initially mistaken as a case of keratoconus.

Methods: A 26-year-old Chinese female hydrogel lens wearer presented with an interest in refractive surgery. After topographies and pachymetries were performed, keratoconus was initially diagnosed for her right eye and suspect keratoconus diagnosed for her left eye.
