ABTRACT Tear film proteins are known to adsorb to new hydrogel contact lenses. Using a radioiodine tracing technique, proteins were shown to adsorb to contact lens surfaces. The quantity of protein adsorbed to the contact lenses within 2 to 4 h was 1 to 3 /µg/lens. The degree of protein adsorption varied from lens-to-lens depending in part on the water content of the lens. High water content ionic lenses bound the most protein, whereas lower water content and nonionic lenses bound less protein… Expand
In Vitro Adsorption of Tear Proteins to Hydroxyethyl Methacrylate-Based Contact Lens Materials
Binding of proteins to hydroxyethyl methacrylate-based hydrogel lens surfaces is affected by charge and polymer components, and perhaps manufacturing processes, and this may play an adverse role during contact lens wear. Expand

Proteins are a key component in body fluids and adhere to most biomaterials within seconds of their exposure, and newer approaches incorporating phosphorylcholine, polyethers or hyaluronic acid into potential contact lens materials result in reduced protein deposition rates compared to current lens materials.

The impact of individual material compositions, water content, hydrophobicity and electrostatic attraction on the adsorption behavior of the protein albumin is summarized. Expand
Biological and Clinical Implications of Lysozyme Deposition on Soft Contact Lenses
It is suggested that deposition of lysozyme on contact lens materials may provide a number of beneficial effects during contact lens wear. Expand
Human serum albumin adsorption on hydrogel contact lenses in vitro.
Ireversible binding of HSA on lenses is governed by the kinetics of protein denaturation, and Electrostatic interactions may not play a major role in HSA adsorption on hydrogel lenses. Expand
In Vitro Effect of Lysozyme on Albumin Deposition to Hydrogel Contact Lens Materials.
It is demonstrated that lysozyme deposited onto etafilcon A resists the deposition of albumin, which may potentially be beneficial to CL wearers. Expand
Efficacy of an Extraction Solvent Used to Quantify Albumin Deposition on Hydrogel Contact Lens Materials
Although TFA/ACN is efficient at extracting albumin deposited on etafilcon lenses, it does not extract all the albumin that is deposited on SH lenses and alternative extraction procedures should be sought. Expand

The “passive” protein removal performance during soaking/disinfection of two multipurpose solutions was investigated and indicated low. Expand
