This patient was diagnosed with an advanced case of keratoconus over 20 years ago. For most of these years he wore small rigid gas permeable lenses that irritated his corneas and provided poor vision. Four years ago his left cornea became severely scarred and he could no longer wear any lens on that eye. Four years ago he was fit with GVR scleral lenses which have provided him with clear (20/20 vision), comfortable vision with all day wear. Over the last four years the scarring in his left cornea has cleared significantly and the vision in his left eye has improved to 20/20.
