Abstract: Disclosed are co-polymers which are produced from reactive monomer mixtures and which have both high refractive index and a high Abbe number. These materials are well suited for use as implantable ophthalmic devices and have a refractive index which may be edited through application of energy. When used for an intraocular lens, the high refractive index allows for a thin lens which compresses to allow a small incision size.

Abstract: Disclosed are hydrophobic, acrylic materials having both high refractive index and a high Abbe number. The materials may have an internal wetting agent, are well suited for use as implantable ophthalmic devices, and have a refractive index which may be edited through application of energy. When used for an intraocular lens, the high refractive index allows for a thin lens which compresses to allow a small incision size.

Abstract: An intra-oral device for positioning oral tissues during medical treatment, for example, radiation treatment. The device includes upper and lower dental arch members configured to engage the maxillary and mandibular teeth or edentulous arch(es) of a patient, respectively. The upper and lower dental arch members are operatively coupled to provide a dental arch assembly. A protective element to displace or depress a patient's tongue is secured at a suitable working position with respect to the dental arch assembly. In an embodiment, provision is made for three-dimensional spatial adjustment of the protective element to a desired location, at least during initial fitting and assembly. The device is then secured to allow consistent repetition of the oral tissue positioning from treatment to treatment. The protective element may be configured to engage the tongue of a patient so that the tongue may be selectively positioned for treatment and/or diagnostic procedures.

Abstract: A magnetic knife guard that attaches to one side of a knife and enables a user to safely and easily store individual knives in a drawer or hang individual knives on kitchen utensil racks without damaging or dulling the cutting surface of the knife. An embedded magnet within the guard holds the guard to the blade while a plurality frictional contact pads prevent slipping or rotation of the guard on the blade.

Abstract: An intra-oral device for protecting oral tissues during radiation treatment is disclosed. In an embodiment, the device includes substantially a U-shaped upper member and lower members coupled to the upper member at their first and the second ends, and a substantially oval-shaped protective element disposed between the first ends of the upper and lower members and the second ends of the upper and lower members and movably coupled with one of the upper or lower members so as to provide for a three-dimensional spatial adjustment of the protective element between the first and second ends of the upper and lower members. The upper and lower members are configured to receive upper and lower teeth of a patient and the protective element is configured to engage a tongue of the patient so that the tongue is selectively positioned for treatment and/or diagnostic procedures.
