The technique of measurement of intraocular lens surface roughness using Atomic Force Microscopy

Lewandowska M.

Interdisciplinary Journal of Engineering Sciences

2014

Vol. 2, no. 1

21--25

Roughness of surface of Intraocular Lens plays an important role, which can provide important information on the interaction between the surface of the implanted lens and lens capsule, among others. Although surfaces appear smooth to the naked eye, they are quite rough at the microscopic levels. The paper presents a technique for measuring surface roughness using AFM. It was found that the size of the scan area does not significantly affect the two standards parameters describing the surface roughness profile (Sa and Sq), however, significantly affect the parameters describing the shape irregularities (Ssk and Ska).
