Ophthalmic coatings

H. Sheardown and L. Subbaraman,     McMaster University, Canada


Materials such as hydrogels have a long history of use in the eye. The need for ophthalmic coatings arises because desired surface properties, such as low fouling and lack of bacterial adhesion, are often inconsistent with the properties necessary in the bulk materials. Commercially, a host of different modifications are used to generate the desired surface characteristics. Contact lens materials have been modified with internal wetting agents or with plasma coatings. Intraocular lenses are often modified to improve implantability and outcomes. Furthermore, while there is much research on ‘typical’ modifications, novel modifications to alleviate ...
