  • Apparatus for modelling ocular structures
    Patent number: 10952609
    Abstract: An imaging system for an optical element, the imaging system comprising means for illuminating a targeted optical element with at least one incident light beam and means for directing at least two light beams returning from at least one surface of the illuminated optical element onto a detector; the detector adapted to measure relative light characteristics of the at least two returning light beams and to calculate at least one parameter of the optical element using the measured characteristics of the at least two returning light beams.
    Type: Grant
    Filed: August 3, 2018
    Date of Patent: March 23, 2021
    Inventors: Eugene Ng, Alexander Goncharov, Patrick Collins
  • Ocular modeling methods and apparatus
    Patent number: 10485416
    Abstract: A method and apparatus for modelling a lens (104) of an eye (100), comprising: measuring (302) the anterior shape of the eye's cornea (102); determining (304) direct optical measurements of at least one parameter of the cornea (102) of the eye (100) and at least one parameter of the lens (104) of the eye (100); determining (306) the refractive index of the cornea; correcting (308) the optical measurements to account for the effect of the refractive index of the cornea on the direct optical measurements; measuring (310) the aberration of the eye; calculating (312) the refractive index of the lens by combining the corrected measurements and the aberration; and further correcting (314) the optical measurements of the lens to account the effect of the refractive index of the lens on the direct optical measurements.

  • OCULAR MODELING METHODS AND APPARATUS
    Publication number: 20180092524
    Abstract: A method and apparatus for modelling a lens (104) of an eye (100), comprising: measuring (302) the anterior shape of the eye's cornea (102); determining (304) direct optical measurements of at least one parameter of the cornea (102) of the eye (100) and at least one parameter of the lens (104) of the eye (100); determining (306) the refractive index of the cornea; correcting (308) the optical measurements to account for the effect of the refractive index of the cornea on the direct optical measurements; measuring (310) the aberration of the eye; calculating (312) the refractive index of the lens by combining the corrected measurements and the aberration; and further correcting (314) the optical measurements of the lens to account the effect of the refractive index of the lens on the direct optical measurements.
