Biocompatibility and cytotoxicity study of nanophotonic rigid gas permeable contact lens material
Since materials on nanoscale have different characteristics from materials on macro scale their biocompatibility should be precisely and specifically investigated. Fullerenes, the third carbon allotrope, are one of the most used nanomaterials. The least stable and the most common is fullerene C60. One of the main disadvantages of fullerene is its low solubility in water. In order to make it sol...
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...
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 کاملImpact of rigid gas-permeable contact lens extended wear on corneal epithelial barrier function.
PURPOSE To measure the effect of hypoxia and eye closure on epithelial permeability to fluorescein (P(dc)) during rigid lens extended wear (EW). METHODS Central corneal thickness (CT) and P(dc) were measured in 42 subjects with an optical pachometer and automated scanning fluorophotometer, respectively. All subjects had been successfully wearing rigid gas-permeable (RGP) lenses on a 6-night E...
متن کاملMigration of rigid gas permeable contact lens into the upper eyelid after trauma: a case report
BACKGROUND Migration of a rigid gas permeable (RGP) contact lens after trauma is rare, and its clinical characteristics have not been fully discussed. CASE PRESENTATION A 36-year-old female showed mild swelling in the right upper eyelid. She lost her RGP contact lens seven months prior to her first visit, from trauma by her child's kick to the right eye. At the first examination, we felt a fi...
