  • Publication number: 20210315452
    Abstract: Devices, systems, and methods that facilitate optical analysis, particularly for the diagnosis and treatment of refractive errors of the eye. An optical diagnostic method for an eye includes obtaining a sequence of aberration measurements of the eye, identifying an outlier aberration measurement of the sequence of aberration measurements, and excluding the outlier aberration measurement from the sequence of aberration measurements to produce a qualified sequence of aberration measurements. The sequence of aberrations measurements can be obtained by using a wavefront sensor. An optical correction for the eye can be formulated in response to the qualified sequence of aberration measurements.

  • Patent number: 10709606
    Abstract: A method of modifying a refractive profile of an eye having an intraocular device implanted therein, wherein the method includes determining a corrected refractive profile for the eye based on an initial refractive profile, identifying one or more locations within the intraocular device based on the corrected refractive profile, and directing a pulsed laser beam at the locations to produce the corrected refractive profile. A system of modifying an intraocular device located within an eye, wherein the system includes a laser assembly and a controller coupled thereto. The laser assembly outputs a pulsed laser beam having a pulse width between 300 picoseconds and 10 femtoseconds. The controller directs the laser assembly to output the pulsed laser beam into the intraocular device. One or more slip zones are formed within the intraocular device in response thereto, and the slip zones are configured to modify a refractive profile of the intraocular device.

  • Publication number: 20180064579
    Abstract: Systems and methods for removing an epithelial layer disposed over a stromal layer in a cornea irradiate a region of the epithelial layer with a pulsed beam of ablative radiation. The ablative radiation is scanned to vary the location of the beam within the region in accordance with a pulse sequence. The pulse sequence is arranged to enhance optical feedback based on a tissue fluorescence of the epithelial layer. The penetration of the epithelial layer is detected in response to the optical feedback. The use of scanning with the pulse sequence arranged to enhance optical feedback allows large areas of the epithelium to be ablated such penetration of the epithelial layer can be detected.

  • Publication number: 20170189168
    Abstract: An intraocular lens for providing vision to a subject contains an optic, a support structure coupled to the optic. The intraocular lens also includes a textured surface and/or subsurface layer. The optic is disposed about an optical axis and comprises an anterior surface and an opposing posterior surface, the surfaces being configured to focus light when implanted within an eye having a capsular bag. The textured surface is disposed over a surface portion of the intraocular lens and includes a plurality of periodically-spaced protrusions, each protrusion having a smooth distal face and a sharp corner edge configured to engage a wall of the capsular bag and/or at least one cell disposed along the wall.

  • Patent number: 9662006
    Abstract: Methods and systems for obtaining an ocular aberration measurement of an eye of a patient are provided. Exemplary techniques involve obtaining a first induced metric for the eye that corresponds to a first accommodation state of the eye, obtaining a second induced metric for the eye that corresponds to a second accommodation state of the eye, and determining a natural metric of the eye based on the first and second induced metrics. An induced metric may include a pupil size or a spherical aberration. Techniques can also include determining a target metric for the eye base on the natural metric, determining whether an actual metric of the eye meets the target metric, obtaining an ocular aberration measurement of the eye if the actual metric meets the target metric, and determining a treatment for the eye based on the ocular aberration measurement.

The optic is disposed about an optical axis and comprises an anterior surface and an opposing posterior surface, the surfaces being configured to focus light when implanted within an eye having a capsular bag. The textured surface is disposed over a surface portion of the intraocular lens. The subsurface layer is configured to scatter an amount of light that is at least twice the amount of light scattered by portions of the material adjacent the subsurface layer or at least twice the amount of light scattered by another intraocular lens that does not have the subsurface layer, but which is otherwise substantially equivalent.
