Soft Contact Lens Surface Profile by Atomic Force Microscopy

Purpose. This study was designed to qualitatively and quantitatively characterize the surface morphology of four unworn conventional hydrogel contact lenses (omafilcon, hioxifilcon, nelfilcon A, and ocufilcon B) and two silicone-hydrogel contact lenses (senofilcon A and comfilcon A) without surface treatment. Methods. Surface roughness was assessed using atomic force microscopy in Tapping ModeTM to determine the representative roughness...
