Corneal changes in soft contact lens wearers

Abstract

There is abundance of physiological and pathological evidence of individual variations in response to soft contact lens wear. Purpose of the study was to observe and to measure changes in corneal curvature, corneal endothelium, corneal thickness and tear-film status that might occur following soft contact lens wear over a period of 1 year. A prospective study was conducted from November 2009 to October 2011. Thirty subjects, 20 females and 10 males, in the age group of 15-30 years who were fitted with Bausch & Lomb soft contact lenses for the first time, on a 10-12 hours daily wear basis, were evaluated for changes in corneal curvature, corneal endothelium, corneal thickness and tear-film status that might occur following soft contact lens wear over 1 year. We concluded that soft contact lens used on a daily wear basis induces changes in corneal curvature, endothelium, thickness and tear-film status.
