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… 

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.

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.

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.

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.

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.

Effectiveness of No-Rub Contact Lens Cleaning on Protein Removal: A Pilot Study

Not all no-rub contact lens solutions were shown capable of removing the protein deposit from soft contact lenses.

A novel procedure for the extraction of protein deposits from soft hydrophilic contact lenses for analysis.

The ACN/TFA procedure offers a simple, quick, and efficient extraction technique for removal of protein from contact lenses for subsequent analysis.
