Visual outcome in Keratoconus with spherical rigid gas permeable contact lens

open access: yesJournal of Institute of Medicine Nepal, 2018
Introduction: Keratoconus is a bileteral asymetric progressive ecteria of cornea commonly associated with vernal keratoconjunctivitis and Atopic dermatitis. Rigid gas permeable (RGP) contact lens is the first choice for refractive correction in keratoconic eyes.
