Corneal deswelling response to hard and hydrogel extended wear lenses.
The amount of initial corneal swelling and the time course of corneal deswelling were measured after overnight wear of several types of hard and hydrogel lenses. Deswelling occurred in the right eye with the lens still on the cornea. In the left eye the lens was removed at eye opening and left off the cornea during deswelling. For lenses of equal nominal oxygen transmissibility, hard lenses ini...
متن کاملExtended wear soft contact lenses induce corneal epithelial changes.
The purpose of this study was to determine the corneal epithelial alterations induced by various types of contact lenses. By employing the specular microscope, the corneal epithelia of 60 patients who had worn contact lenses for more than 1 year were re-examined along with 15 myopic controls. The morphological changes in aphakic patients who changed from extended wear soft to extended wear rigi...
متن کاملCorneal epithelial permeability during extended wear of disposable contact lenses versus daily wear of soft contact lenses.
AIMS The corneal epithelial permeability during extended wear of disposable contact lenses was compared with that during daily wear of soft contact lenses. The study was performed to verify whether the extended wear of disposable contact lenses would result in a higher permeability value than the daily wear of soft contact lenses. A higher permeability makes the cornea more vulnerable for bacte...
متن کاملPredictive factors for corneal infiltrates with continuous wear of silicone hydrogel contact lenses.
OBJECTIVE To estimate the cumulative probability and risk factors for developing corneal infiltrates after up to 3 years of continuous wear (CW) with lotrafilcon A lenses. METHODS Patients were fitted with lotrafilcon A lenses and followed up for 3 years. The main outcome variable was the first occurrence of any infiltrative event in either eye. Cox proportional hazards regression was used to...
متن کاملEffects of long-term soft contact lens wear on the corneal thickness and corneal epithelial thickness of myopic subjects.
To perform safe and successful corneal refractive surgery on myopic patients, corneal thickness (CT) and corneal epithelial thickness (CET) must be accurately measured. Numerous individuals with myopia wear soft contact lenses (SCLs) for the correction of visual acuity but may subsequently undergo corneal refractive surgery. The aim of the present study was therefore to investigate the effects ...
