  • Patent number: 6919321
    Abstract: Ocular lubricant solutions are described. The solutions are adapted to facilitate the formation of a corneal flap during LASIK surgery. The solutions contain one or more viscosity enhancing agents (e.g., chondroitin sulfate) in a substantially salt-free, ophthalmically acceptable vehicle. Methods of lubricating the cornea to facilitate flap formation are also described.
    Type: Grant
    Filed: November 29, 2001
    Date of Patent: July 19, 2005
    Assignee: Alcon, Inc.
    Inventors: Pao-Li Wang, Uday Doshi, Masoud R. Jafari, Kerry L. Markwardt, Emerson Maddox
  • Patent number: 6878694
    Abstract: Compositions and methods for facilitating the formulation and closure of a corneal flap during LASIK surgery are described. The compositions and methods are based on the use of one or more viscosity-enhancing agents (e.g., chondroitin sulfate) to provide an ophthalmic irrigating solution with improved coating properties and prolonged dwelling time on the cornea, thereby providing lubrication for the microkeratome used to form the corneal flap, reduce corneal epithelial abrasions, and help to produce smooth and consistent cuts with the microkeratome blade.
