  • Patent number: 8403919
    Abstract: A method for optimizing a prescription for laser-ablation corneal treatment includes receiving a measured correction prescription for a current patient. Next a database of treatment outcomes on a plurality of previously treated patients is accessed. The database contains a desired correction, and an actual correction. A difference between the desired correction and the actual correction represents an over- or undercorrection resulting from surgery. From the difference data is calculated a distribution of data points as a function of correction level. From the data-point distribution is calculated a statistically based offset applicable to the correction prescription for matching actual corrections with desired corrections. From the data-point distribution is calculated a confidence interval of the data using a predetermined confidence level. The statistically based offset is then adjusted based upon the confidence interval to provide an optimized prescription.

    Abstract: A photodisruptive laser delivery system and method for use in eye surgery. The photo disruptive laser delivered in pulses in the range of <10000 femtoseconds, used to create incisions in eye tissue is delivered by novel means to minimize optical aberrations without the use of a complex system of multiply precisely arranged lenses. This novel means include a scanning design that allows the focusing lens to always remain under normal incidence to the photodisruptive laser beam, negating the need for overly complex aberration correction set up. The focusing lens is configured to move within a surrounding beam to facilitate two dimensional controls over the treatment space. Controlling beam divergence prior to focusing allows for 3D incisions. The system and methods of use accomplish precise treatment without the need to contact the patient and can be integrated into standard surgical microscopes to improve operational efficiency and hospital workflow.

  • Publication number: 20100324543
    Abstract: A method for integrated eye surgery can include determining a cataract-target region in a lens of the eye; applying cataract-laser pulses to photodisrupt a portion of the determined cataract-target region; determining a glaucoma-target region or an astigmatism-target region in a peripheral region of the eye; and applying surgical laser pulses to create one or more incisions in the glaucoma- or astigmatism-target region by photodisruption; wherein the steps of the method are performed within an integrated surgical procedure. The laser pulses can be applied before making an incision on a cornea of the eye. The integrated surgical procedure may involve using the same pulsed laser source for three functions: for photodisrupting the target region, for making an incision on the capsule of the lens and for making an incision on the cornea of the eye.
