Purpose To evaluate the safety and efficacy of Focus® Night & Day™ extended-wear
contact lenses when used for therapeutic purposes. Methods Fifty eyes of 50 consecutive …

Purpose. To characterize the epithelial thickness profile and study the effects of long-term
wear of hydrogel lenses on this profile. Methods. A cross-sectional study was designed …

The aim of this study was to evaluate corneal innervation in soft contact lens wearers using
the Tomey Confoscan confocal microscope (40×/0.75 objective lens). Three distinct age …

Purpose. Despite numerous studies that have considered the effects of extended wear of
high-Dk soft contact lenses on ocular physiology, little attention has been paid to the impact …

Methods Eighty-four eyes of 45 patients (26 female and 19 male) wearing contact lens for
the first time with a median age of 23.04±7.2 years (range, 15–44 years) were included in …

PURPOSE: To compare central corneal thickness measurements as a function of contact
lens wear in patients presenting for refractive surgery. SETTING: Gimbel Eye Centre …

Contact lens extended wear increases the permeability of epithelium to sodium fluorescein
(Pdc). The exact mechanism is not known. However, changes in Pdc likely result from either …

ABSTRACT PURPOSE: We evaluated the reliability and agreement between the Orbscan,
an ultrasonic pachymeter (Humphrey 855), and the Konan SP 9000-LC in terms of central …

Purpose. To evaluate changes in corneal thickness after 2, 4, and 6 weeks of frequent-
replacement contact lens wearing. Material and Methods. Twenty-eight patients were fitted …

Purpose. To determine recovery time needed for the corneal epithelium to return to a normal
proliferation rate following 24-hour rigid gas-permeable (RGP) lens wear. Methods. An RGP …
