    摘要： High refractive index copolymers suitable for use in ophthalmic devices are disclosed. The copolymers comprise two or more aryl hydrophobic monomers and a non-polymerizable propylene oxide-ethylene oxide-propylene oxide block copolymer surfactant having a molecular weight of approximately 3600 and approximately 40% ethylene oxide units by weight. The copolymers have a reduced tendency to form glistenings when stored in water at physiological temperatures compared to similar copolymers lacking the non-polymerizable surfactant.

    摘要： A system for controlling the residual moisture in pre-cured binder coated glass fibers. The moisture of the binder coated glass fibers is measured after the process water is extracted in a collection box. Based on the level of moisture found in the coated glass fibers, adjustments are made to the process upstream of the moisture measurements. The adjustments include, but are not limited to, adjusting the amount of water used to make the binder composition; adjusting the amount of heat applied to the binder composition as it is applied to the glass fibers and adjusting the vacuum conditions used to extract the process water from the binder coated glass fibers. Control of the residual moisture in the precured binder coated glass fibers helps ensure proper curing of the binder during the subsequent curing step.

    摘要： High refractive index copolymers suitable for use in ophthalmic devices are disclosed. The copolymers comprise a single aryl hydrophobic monomer as a device forming monomer. In addition, the copolymers comprise a non-polymerizable block copolymer surfactant. The copolymers have a reduced tendency to form glistenings when stored in water at physiological temperatures.

    摘要： Disclosed are soft, high refractive index, acrylic materials having an elongation of at least 150%. These materials, especially useful as intraocular lens materials, contain an aryl acrylic hydrophobic monomer as the single principal device-forming monomer. In addition to their use as intraocular lens materials, the present materials are also suitable for use in other ophthalmic or otorhinolaryngological devices, such as contact lenses, keratoprostheses, corneal inlays or rings; otological ventilation tubes and nasal implants.
