Estimation of the hybrid lens parameters through rigid gas permeable lens fitting
PURPOSE To estimate the fitting parameters of the hybrid contact lens in patients with corneal ectasia using the rigid gas permeable (RGP) lens. METHODS Thirty-four eyes with corneal ectasia were evaluated in this study. The patients were examined once with the RGP lens and once with the hybrid contact lens. The relationship between the base curvature of the RGP and the vault of the hybrid le...
متن کاملOptimal time following fluorescein instillation to evaluate rigid gas permeable contact lens fit.
PURPOSE To examine the optimum time at which fluorescein patterns of gas permeable lenses (GPs) should be evaluated. METHODS Aligned, 0.2mm steep and 0.2mm flat GPs were fitted to 17 patients (aged 20.6 ± 1.1 years, 10 male). Fluorescein was applied to their upper temporal bulbar conjunctiva with a moistened fluorescein strip. Digital slit lamp images (CSO, Italy) at 10× magnification of the ...
متن کاملRigid Gas Permeable Contact Lens as a Vision-Sparing Tool in Children After Traumatic Corneal Laceration.
PURPOSE To evaluate the clinical value of rigid gas permeable contact lenses in children after traumatic corneal scarring. METHODS This comparative study included 15 children (age range: 5.7 to 14 years; mean ± standard deviation = 9.4 ± 2.9 years) with corneal scars and best corrected visual acuity (BCVA) of worse than 20/20, history of penetrating ocular trauma, and/or cataract extraction. ...
متن کاملPeripheral myopization and visual performance with experimental rigid gas permeable and soft contact lens design.
PURPOSE To evaluate the performance of two experimental contact lenses (CL) designed to induce relative peripheral myopic defocus in myopic eyes. METHODS Ten right eyes of 10 subjects were fitted with three different CL: a soft experimental lens (ExpSCL), a rigid gas permeable experimental lens (ExpRGP) and a standard RGP lens made of the same material (StdRGP). Central and peripheral refract...
متن کاملComparative study of antibacterial and antifungal effects of rigid gas permeable contact lens disinfecting solutions.
The aim of this study was to compare antimicrobial efficacy of rigid contact lens disinfecting solutions. We tested five commercially available solutions: Unique pH (Alcon Laboratories), Boston Advance (Polymer Technology Corp.), Nitilens Conditioner GP (Avizor), Total Care (AMO), Boston Simplus (Bausch&Lomb). Their efficacy to disinfect saline solution experimentally contaminated with American...
