Critical oxygen levels to avoid corneal edema for daily and extended wear contact lenses.
The relationship between corneal edema and hydrogel lens oxygen transmissibility was examined for both daily and extended contact lens wear by measuring the corneal swelling response induced by a variety of contact lenses over a 36-hr wearing period. The relationships derived enable average edema levels that occur with daily and extended wear in a population of normal young adults to be predict...
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 کاملContact lens-related adverse events and the silicone hydrogel lenses and daily wear care system used.
OBJECTIVE To investigate the incidence of adverse events related to the use of varying silicone hydrogel contact lens and lens solution combinations. METHODS Individuals with myopia (N = 558) participated in 1 or more of approximately 40-participant trials in a matrix of 20 silicone hydrogel contact lens and lens-solution combinations. Visits were at baseline, 2 weeks, 1 month, and 3 months. ...

متن کاملProteomic analysis of protein deposits on worn daily wear silicone hydrogel contact lenses
PURPOSE Previous studies have demonstrated deposition of tear proteins onto worn contact lenses. In this study, we used proteomic techniques to analyze the protein deposits extracted from worn daily wear silicone hydrogel contact lenses in combination with different lens care solutions. METHODS Worn lenses were collected and protein deposits extracted using urea and surfactant. Protein extrac...
