  • Methods of fabricating a collagen lenticule precursor for modifying the cornea
    Patent number: 5288436
    Abstract: A lenticule is bonded to the eye as part of its formation process by curing or final curing the lenticule on the eye. Such lenticules provide a smooth transition from the body of the lenticule to Bowman's layer on which the lenticule is disposed. The lenticule at the time its material or precursor is placed on the eye may vary from being essentially all viscous collagen which flows and must be molded to obtain a desired lenticule configuration to a substantially stable preform which holds its own shape. Such preformed lenticules may be formed using an appropriate mold and photopolymerization or other partial curing techniques to pre-cure the lenticule material to an appropriate stage for application to the eye.
    Type: Grant

  • Apparatus and process for application and adjustable reprofiling of synthetic lenticules for vision correction
    Patent number: 5196027
    Abstract: An apparatus and process for applying a synthetic lenticule to the cornea of a human eye is disclosed, the process also contemplating selective reprofiling of the lenticule while it is in place over the cornea. The process involves securing the lenticule over the cornea with an adhesive, thus leaving the visual axis of the eye undisturbed or with the peripheral edge thereof being retained by a peripheral slit. A laser delivery system is used to reprofile the lenticule if necessary for refining the refractive power of the lenticule.
