Abstract: A method of treating a lens of a patient's eye includes generating a light beam, deflecting the light beam using a scanner to form a treatment pattern of the light beam, delivering the treatment pattern to the lens of a patient's eye to create a plurality of cuts in the lens in the form of the treatment pattern to break the lens up into a plurality of pieces, and removing the lens pieces from the patient's eye. The lens pieces can then be mechanically removed. The light beam can be used to create larger segmenting cuts into the lens, as well as smaller softening cuts that soften the lens for easier removal.

Abstract: A laser scanning method for forming a Fresnel type gradient index lens in an intraocular lens IOL. The radial profile of the desired optical pathlength (OPL) difference to be achieved in the IOL has multiple zones, each zone ramping from unchanged OPL to one wave, and stepping down to zero. To form a zone of a predefined OPL difference profile, the laser beam is scanned in multiple passes; in each pass, the laser beam is scanned in concentric circles of varying radii covering all or a part of the zone, with laser energy ramping up (along the radius) to a maximum allowed energy and staying at that energy. The ramp up region, which is dependent on the predefined OPL difference profile and the maximum allowed energy, is short, and most part of the pass is scanned at the maximum allowed energy.

Abstract: A method of altering a refractive property of a crosslinked acrylic polymer material by irradiating the material with a high energy pulsed laser beam to change its refractive index. The method is used to alter the refractive property, and hence the optical power, of an implantable intraocular lens after implantation in the patient's eye. In some examples, the wavelength of the laser beam is in the far red and near IR range and the light is absorbed by the crosslinked acrylic polymer via two-photon absorption at high laser pulse energy. The method also includes designing laser beam scan patterns that compensate for effects of multiphone absorption such as a shift in the depth of the laser pulse absorption location, and compensate for effects caused by high laser pulse energy such as thermal lensing. The method can be used to form a Fresnel lens in the optical zone.

Abstract: Methods and related apparatus for real-time process monitoring during laser-based refractive index modification of an intraocular lens. During in situ laser treatment of the IOL to modify the refractive index of the IOL material, a signal from the IOL is measured to determine the processing effect of the refractive index modification, and based on the determination, to adjust the laser system parameters to achieve intended processing result. The signal measured from the IOL may be a fluorescent signal induced by the treatment laser, a fluorescent signal induced by an external illumination source, a temporary photodarkening effect, a color change, or a refractive index change directly measured by phase stabilized OCT.
