Bubendorf, Switzerland, November 2015 — CIS Pharma is expanding its Cellophil® Smart Polymer platform with new bio-inspired derivatives. The derivatives are used as building blocks for the development of a novel contact lens coating technology. The Cellophil® Smart Polymer coating technology aims to improve the wettability of silicone hydrogel contact lenses. In addition, the coating is designed to prevent the adsorption of proteins and lipids onto the contact lens. The targeted coating procedure can be integrated into current industrial contact lens manufacturing processes.

About contact lens materials

The latest generation of contact lens materials is a combination of hydrogel and silicone materials. Silicone has high oxygen permeability but only a limited wettability and is thus not optimal for use on the eye. The contact lens surface is therefore currently treated with plasma to form hydrophilic silica islands, ensuring that the lenses having high oxygen permeability without affecting the lubricity and wear comfort.
