An Objective Method to Determine the Ocular Refraction from Wavefront Aberration Data and to Design an Optimum Customized Correction of a Set of a Few Higher-Order Aberrations
URV Reference Number:
This invention provides a method to compute the correction necessary to correct for abberations in an eye of a patient, using wavefront data.
For the automated determination of an accurate, optimum refraction correction for spectacles or contact lenses, without requiring subjective input from the patient.
It enables the use of advanced wavefront diagnostic technology for routine eye exams. The process will simplify and partially automate the work process in the retail optical environment of optometrists and dispensing ophthalmologists.
Unlike earlier auto-refractors, this technology provides accurate determination of the refraction correction, by taking advantage of all the data available in a wavefront sensor such as a Shack Hartmann detector. It can also be used for the prescription of advanced refraction corrections to address higher order aberrations than those typically corrected by conventional spectacles.
A complete and accurate characterization can be obtained in a fraction of a second.
