    摘要: The present invention is directed to an ophthalmic solution for soft contact lenses for controlled release of polyethers into an eye's tear film. Polyether components of the subject solution are released from the soft contact lens material matrix over long time periods to produce longer lasting wetting performance, improved lubricity, improved end-of-the-day comfort and reduced feeling of dryness from wearing contact lenses. The present invention also includes the use of cationic polyelectrolytes for controlling the swelling of hydrogel contact lenses typically caused by the absorption of high concentrations of polyethers.

    摘要: The invention provides a method for improving the wettability of a medical device, comprising the steps of: (a) providing a medical device formed from a monomer mixture comprising a hydrophilic monomer and a silicone-containing monomer, wherein said medical device has not been subjected to a surface oxidation treatment; (b) contacting a surface of the medical device with a solution comprising a proton-donating wetting agent, whereby the wetting agent forms a complex with the hydrophilic monomer on the surface of the medical device in the absence of a surface oxidation treatment step and without the addition of a coupling agent.

    摘要: A minus power anterior chamber ocular implant for placement in the anterior chamber of a phakic eye having an anatomic lens in situ comprises a negative artificial refracting lens having at least one concave surface, a surface coating which comprises a compatible sulfated polysaccharide medicament coating, such as heparin, and having a structure which positions the artificial lens in the anterior chamber of the eye to prevent contact between the implant and the anatomic lens. The implant compensates for refractive errors or creates a specific refraction to assist in visual function and has increased biocompatibility in the anterior chamber of the eye, thereby preventing or mitigating detrimental effects typically associated with the implantation of an uncoated refractive anterior chamber implant in the eye. A method of preparing such a minus power anterior chamber ocular implant comprises first exposing an uncoated implant to a plasma to generate a plasma-treated implant having a surface containing amines, carboxylic acids, active free radicals or passive free radicals, and thereafter bonding the medicament to the plasma-treated implant surface. A method of treating myopia comprises surgically implanting and anchoring the implant in the phakic eye to compensate for refractive errors.

    摘要: An improved soft contact lens material, existing as a hydrogel, is formed by a polymer containing a fluorinated monomer, a hydroxyalkyl ester of acrylic or methacrylic acid, and an N-vinyl lactam. The polymer may also contain other hydrophilic and/or hard hydrophobic monomers, crosslinking agents, and uv-absorbing agents. Contact lenses made of these combinations have high water of hydrations, are highly wettable, have extremely high oxygen permeabilities and are resistant to protein deposits and other forms of attached debris.
