Corneal changes in soft contact lens wearers
Journal of Clinical Ophthalmology and Research, 2016 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-
