Patents by Inventor Christine Liau

Christine Liau has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20140277438
    Abstract: Ophthalmic devices suitable for implantation into the eye through small incisions or insertion into an existing orifice are disclosed. These devices are made from a composition comprising crystalline or semi-crystalline polymeric materials which have a glass transition temperature (Tg) of from about ?100° C. to about 37° C., and wherein Tg for the material is lower than Tm for the composition. Disclosed devices include intraocular lenses, corneal inlays, drug delivery devices and implants for reducing intraocular pressure in glaucoma patients.

  • Publication number: 20050283234
    Abstract: Intraocular lenses containing a photochromic agent having its maximum absorption peak in the wavelength range of about 400-500 nm, are disclosed. Methods for making these intraocular lenses are also taught.

  • Patent number: 6679605
    Abstract: Ophthalmic devices suitable for implantation into the eye through small incisions are disclosed. These devices are made from a composition comprising crystalline or semi-crystalline polymeric materials which have a glass transition temperature (Tg) of from about −100° C. to about 20° C., a melting point temperature (Tm) of from about 0° C. to about 37° C., and wherein Tg for the material is lower than Tm for the composition. Disclosed devices include intraocular lenses, corneal inlays, ocular drug delivery devices and implants for reducing intraocular pressure in glaucoma patients; intraocular lenses are preferred.

  • Publication number: 20030033015
    Abstract: A method for treating presbyopia using a scleral insert is described. The scleral insert is prepared from either (or both) of two specific classes of polymeric materials having both viscous and elastic properties. The first class of polymeric materials has a glass transition temperature (Tg) at or below human body temperature (37° C.). The second class of polymeric materials has a melting temperature (Tm) at or below human body temperature (37° C.). The implant is stored in a frozen, rigid, elongated state prior to insertion in to the eye. Once it is placed on or within the sclera the insert responds to the increase in temperature, due to the surrounding physiochemical environment whereby it becomes soft and expands to reach its final shape. This implant can be inserted in to the eye through a much smaller incision than is used with conventional scleral implant techniques.
