Purpose. We sought to determine whether there were differences in lysozyme (quantity and
conformation) and lipid deposition on in vivo worn conventional (etafilcon) and silicone …

Purpose. To determine the activity of hen egg lysozyme (HEL) deposited on conventional
and silicone hydrogel contact lens materials by using an in vitro model. Methods. ACUVUE 2 …

We sought to compare the kinetics of in vitro lysozyme deposition on silicone hydrogel (SH),
polymethyl methacrylate (PMMA), and FDA groups I, II, and IV contact lenses. Lenses were …

Purpose. To determine whether differences in lysozyme deposition and/or activity exist on
worn etafilcon and balafilcon contact lenses following care with a polyquaternium-based …

PURPOSE: To evaluate the influence of surface treatment of silicone-hydrogel CL on lens
hydrophobicity, protein adsorption and microbial colonisation by studying several silicone …

Within a few minutes of wear, contact lenses become rapidly coated with a variety of tear film
components, including proteins, lipids, and mucins. Tears have a rich and complex …

Purpose. To quantitatively detect proteins and cholesterol extracted from worn silicone
hydrogel contact lenses and determine the effect of various lens care solutions on deposit …

PURPOSE: To examine the processes involved in formation of protein deposits on hydrogel
contact lenses. METHODS: The adsorption and/or penetration of lysozyme on or into three …

Purpose. The majority of studies investigating protein deposition on contact lens materials
require that the deposit of interest be removed, potentially resulting in erroneous results if …

Methods.: Ten unworn polymers of nine types were individually soaked in 1.0 mL of 1.75
μg/mL cholesterol oleate or 1.0 mL of 0.5 μg/mL phosphatidylcholine solutions for 1 or 14 …
