The association between two quality of life measures for first time low vision device users
(University of Waterloo, 2006)Many individuals with impaired vision experience a decreased quality of life. Quality of life is defined as "the degree to which an individual enjoys the important possibilities of their life. " Vision rehabilitation ... -
BIOMECHANICAL ALTERATION OF CORNEAL MORPHOLOGY AFTER CORNEAL REFRACTIVE THERAPY
(University of Waterloo, 2006)<strong>Purpose:</strong> Although orthokeratology (non-surgical corneal reshaping, Corneal Refractive Therapy, CRT®) has been used for almost a half century, contemporary CRT's outcomes and mechanisms still require ... -
Central Visual Field Assessment in Late Stage Glaucoma
(University of Waterloo, 2006)Glaucoma is defined as a progressive optic neuropathy, characterized by loss of visual function and often associated with high intra-ocular pressure. Testing the patients' visual function with Standard Automated Perimetry ... -
In vitro and ex vivo wettability of hydrogel contact lenses
(University of Waterloo, 2006)The wettability of contact lenses has become an area of intense research, with the belief that the more "hydrophilic" or wettable the lens surface is, the more comfortable the lens may be, as the posterior surface of the ... -
In Vivo Imaging of Corneal Conditions using Optical Coherence Tomography
(University of Waterloo, 2006)Purposes: To use optical coherence tomography (OCT) to image and quantify the effect of various corneal conditions, in terms of corneal, stromal and epithelial thickness, and light backscatter. To assess the changes ... -
Lipid Deposition on Hydrogel Contact Lenses
(University of Waterloo, 2006)The primary objective of this study was to quantify and characterise lipid deposition on soft (hydrogel) contact lenses, particularly those containing siloxane components. Studies involving a variety of <em>in vitro</em> ... -
Lysozyme Deposition Studies on Silicone Hydrogel Contact Lens Materials
(University of Waterloo, 2005)Over 60 proteins have been detected in the tear film and among these lysozyme has attracted the greatest attention. Several techniques for elucidating the identity, quantity and conformation of lysozyme deposited on soft ... -
Monocular Adaptation of Vestibulo-Ocular Reflex (VOR)
(University of Waterloo, 2005)Purpose: This study asks whether active horizontal angular Vestibulo-Ocular Reflex (VOR) gain is capable of monocular adaptation after 4 hours of wearing 10 dioptres (D) of induced anisometropia in healthy human adults. ... -
Ocular Discomfort Upon Tear Drying
(University of Waterloo, 2003)<b>Purpose:</b> Assess the relationship between tear film drying and sensation between blinks. <b>Methods:</b> MATLAB sampled a slitlamp video camera, a potentiometer and a microphone while subjects kept one eye open ... -
A Study of Saccade Dynamics and Adaptation in Athletes and Non Athletes
(University of Waterloo, 2004)Purpose: The aim of the study was to delineate differences in saccade characteristics between a population of athletes and non athletes. Aspects specifically investigated were latency, accuracy, peak velocity, and gain ... -
Study of the dynamic interactions between vergence and accommodation
(University of Waterloo, 2005)<em>Introduction:</em> Accommodation (change in ocular focus) and Vergence (change in ocular alignment) are two ocular motor systems that interact with each other to provide clear single binocular vision. While retinal ...
