  • Iterative fourier reconstruction for laser surgery and other optical applications
    Publication number: 20050012898
    Abstract: Methods, systems and software for determine an optical surface model for an optical tissue system using Fourier transformation algorithms. A method of reconstructing optical tissues of an eye comprises transmitting an image through the optical tissues of the eye. The surface gradients from the transmitted image are measured across the optical tissues of the eye. A Fourier transform algorithm is applied to the surface gradients to reconstruct an optical surface model that corresponds to the optical tissues of the eye.

  • Presbyopia correction using patient data
    Publication number: 20040169820
    Abstract: Methods, devices, and systems establish an optical surface shape that mitigates or treats presbyopia in a particular patient. The combination of distance vision and near vision in a patient can be improved, often based on input patient parameters such as pupil size, residual accommodation, and power need. Iterative optimization may generate a customized corrective optical shape for the patient.
