Optical Modeling and Analysis of Peripheral Optics of Contact Lenses
Background: Degraded peripheral vision has been hypothesized to be a stimulus for the development of foveal refractive error. Contact lenses have been widely used to correct central vision, but their impacts on peripheral vision are still unknown. The purpose of this study was to use optical model software to evaluate the peripheral optics of rigid gas permeable (RGP) and soft contact lenses (S...
متن کاملExtended-wear aphakic soft contact lenses and corneal ulcers.
A review of 100 aphakic extended-wear soft contact lenses is presented for the period July 1980 to August 1981. Four previously successfully fitted patients with either American Optical Company's Sofcon or Cooper Laboratories' Permalens for extended wear developed corneal ulcers either directly under the lenses or shortly after removal. Three of the female patients were well controlled diabetic...
متن کاملPredicting and assessing visual performance with multizone bifocal contact lenses.
PURPOSE To investigate how bifocal contact lenses, when combined with the aberrations of the eye, will affect visual performance. Also, to investigate the relationship between the patient's predicted and actual visual benefit with bifocal contact lenses. METHODS The monochromatic aberrations of 16 subjects were measured and used to simulate visual quality with three bifocal contact lens desig...
متن کاملMyopia Control with Bifocal Contact Lenses: A Randomized Clinical Trial.
PURPOSE Most studies have reported only minimal reductions in myopia progression with bifocal or progressive multifocal spectacles, although somewhat larger, although mostly still clinically insignificant, effects have been reported in children with nearpoint esophoria and/or accommodative dysfunctions. The CONTROL study was a 1-year, prospective, randomized, clinical trial of bifocal contact l...
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...
