  • Use of sustained release antibiotic compositions in ophthalmic surgical procedures
    Patent number: 6630135
    Abstract: An improved method of sterilizing the field of surgery prior to an ophthalmic surgical procedure is described. The invention eliminates the need for painful and potentially traumatic injections of antibiotics by utilizing sustained release compositions which allow the antibiotics contained therein to penetrate deeply into the eye, thereby ensuring a sterile field of surgery during intraocular surgical procedures. The compositions may also be utilized to prevent post-surgical infections.
    Type: Grant
    Filed: November 12, 1999
    Date of Patent: October 7, 2003
    Assignee: Alcon Laboratories, Inc.
    Inventors: Gerald D. Cagle, Tai-Lee Ke, Barry A. Schlech, Ole J. Lorenzetti
