Biomedical polymers
From the older hard and rigid gas permeable lenses to the latest soft hydrogel lenses worn weekly, monthly, or daily and then disposed, contact lenses have made great strides in providing lens wearers increased comfort and convenience. Today’s intra ocular lenses (IOL) are thinner, foldable and installed with less surgical intrusion.
Advanced moist wound healing products which incorporate hydrogels and deliver active healing ingredients, help heal acute and chronic wounds and improve patient quality of life. Medical devices like cardiac stents and catheters have polymer coatings with optimum surface lubricity to reduce in-surgical trauma and improve post-surgical performance.
Sophisticated hydrogel polymers that possess high oxygen-permeability and high water content combined with various surface modification techniques have made it possible to realize these benefits. Cognis provides an array of products and services for contact lens and IOL manufacturers
