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 investigate the sorption of oleic acid, oleic acid methyl ester, and cholesterol on
currently marketed silicone hydrogel contact lenses. Methods. Two liquid chromatography …

Purpose The purpose of this study was to analyze the impact that incubation time, lipid
concentration, and solution replenishment have on silicone hydrogel (SiHy) and …

Objective: Lipid deposition on silicone hydrogel (SiHy) lenses, which are believed to be
caused by their hydrophobic surface, can lead to discomfort, reduced vision, and …

Purpose The goal of this study was to analyze how various incubation times affect the
uptake of cholesterol on silicone hydrogel (SH) and conventional hydrogel (CH) daily …

Purpose. To correlate clinical responses during contact lens wear with the amount of protein
or cholesterol extracted from lenses after wear. Methods. Clinical parameters, including …

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 …

Purpose. To establish a new analytical method using gas chromatography/mass
spectrometry (GC/MS) for evaluating the lipids adsorbed on silicone hydrogel (SH) contact …

The interaction between a contact lens, the ocular surface, and the tear film is vital for
successful contact lens wear. It has long been known that both organic and inorganic tear …

Purpose: To investigate the mechanism of protein and lipid adherence to hydrophilic contact
lenses in vivo. Methods: Two types of new, never-worn hydrophilic contact lenses (tefilcon …
