  • Ophthalmic lubricating solution adapted for use in lasik surgery
    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.

  • Combinations of viscoelastics for use during surgery
    Publication number: 20040101561
    Abstract: Systems for performing surgery, especially ophthalmic surgery, utilizing multiple viscoelastic agents with differing physicochemical properties are disclosed. The systems enable the skilled surgeon to perform certain steps of a surgical procedure with viscoelastic agents that are particularly well suited for such steps.
