Optical designers of optical systems for the human eye strive to create models that closely
resemble the human eye. Scientists Liou and Brennan have already succeeded in …

We examine a mathematical model describing the behavior of the precontact lens tear film of
a human eye. Our work examines the effect of contact lens thickness and lens permeability …

Purpose: To develop with a thin film interferometer new parameters to describe the drying
properties of contact lenses; these are: time to first break-up (onset latency), duration of lens …

Purpose.: To evaluate the effect of soft contact lens type on the in vivo tear film surface
quality (TFSQ) on daily disposable lenses and to establish whether two recently developed …

Contact lens friction significantly correlates with subjective comfort. Hyaluronan (HA) and
proteoglycan 4 (PRG4) are natural boundary lubricants present in the body. The objective of …

Objective: Recently, a new water gradient silicone hydrogel material has been introduced for
a daily disposable lens. The aim of this study was to assess, in vivo, the prelens tear film …

Purpose With soft-contact-lens wear, evaporation of the pre-lens tear film affects the
osmolarity of the post-lens tear film and this can introduce a hyperosmotic environment at …

Purpose The aim of this study was to evaluate the anterior surface of scleral contact lens and
ocular surface wettability before and after one-month of scleral lens wear in patients with …
