Rigid Gas Permeable Contact Lens Fitting Using New Software in Keratoconic Eyes

Optometry and Vision Science, 2016
To determine the repeatability of the back optic zone radius (BOZR) of rigid gas permeable (GP) contact lens (CL) proposed by new software for fitting in healthy and keratoconus eyes and to compare with the diagnostic CL fitting method.Three consecutive corneal topographies (Oculus-Keratograph) were performed and analyzed with APEX new software CL ...

Corneo-scleral rigid gas permeable contact lens prescribed following penetrating keratoplasty

International Contact Lens Clinic (New York, N Y ), 1998
Abstract Corneo-scleral rigid gas permeable lenses represent a new category of contact lens. Incorporating an overall diameter of approximately 14 to 15 mm, the corneo-scleral lens is larger than a corneal lens yet smaller than a scleral lens. A 39-year-old man was referred to our office for a contact lens fitting following penetrating keratoplasty ...
