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 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 …

Purpose. The purpose of this study was to confirm that two distinct clinical presentations of
contact lens-induced papillary conjunctivitis (CLPC), local and general, occur in hydrogel …

Purpose. To determine the relationship between clinical signs and symptoms and protein
deposition over 8 h of wear of etafilcon A lenses in symptomatic and asymptomatic contact …

Purpose. The purpose of this study was to evaluate the longitudinal changes in ocular
physiology, tear film characteristics, and symptomatology experienced by neophyte silicone …

The main reasons for the discontinuation of contact lens wear are ocular dryness and
discomfort. Proteoglycan 4 (PRG4), a mucinous glycoprotein, and hyaluronic acid (HA), a …

Purpose. This study was designed to qualitatively and quantitatively characterize the surface
morphology of four unworn conventional hydrogel contact lenses (omafilcon, hioxifilcon …

The aim of this study was to qualitatively and quantitatively characterize the optic surface
topography of unworn hydrogel contact lenses (CLs) using atomic force microscopy (AFM) …

Contact lens wearers with giant papillary conjunctivitis report a variety of symptoms,
including decreased lens tolerance, increased lens awareness, excessive lens movement …

Purpose. The purpose of this study is to demonstrate a novel method for measuring the
modulus of contact lenses in their as-received, variable-thickness form and to determine …
