Streszczenie:
The aim of this work was to estimate the multifractal spectra of 3D surface roughness for unworn hydrogel contact lenses (CL), obtained with atomic force microscopy (AFM) analysis. Materials and methods: Contact lenses made from vifilcon A (Focus® Monthly Toric Visitint® model, CIBA Vision Corp.) were investigated. CL surface roughness was studied by AFM in tapping-mode™, in an aqueous environment, on square areas ranging from 1 to 4 μm 2. A detailed methodology for CL surface multifractal ...
