SYSTEMS AND METHODS FOR VERGENCE MATCHING OF AN INTRAOCULAR LENS WITH REFRACTIVE INDEX WRITING
Systems and methods for improving vision of a subject implanted with an intraocular lens (IOL). In some embodiments, a method for vergence matching includes calculating vergence of a wave after refraction on a surface of an IOL and, based on an estimated curvature, converting an initial phase map into a vergence-matched phase map, such that the initial phase map follows the curved vergence of the wavefront.
SYSTEMS AND METHODS FOR SPECTACLE INDEPENDENCE USING REFRACTIVE INDEX WRITING WITH AN INTRAOCULAR LENS
Systems and methods for improving vision of a subject implanted with an intraocular lens (IOL). In some embodiments, a method includes applying a plurality of laser pulses to the IOL. The laser pulses can be configured to produce, by refractive index writing on the IOL, a predetermined change in phase profile of the IOL to increase spectacle independence.
SYSTEMS AND METHODS FOR CORRECTING PHOTIC PHENOMENON FROM AN INTRAOCULAR LENS AND USING REFRACTIVE INDEX WRITING
Systems and methods for improving vision of a subject implanted with an intraocular lens (IOL). In some embodiments, a method includes determining at least one photic phenomenon experienced by the subject after implantation of the IOL; and applying a plurality of laser pulses to the IOL, the laser pulses being configured to produce, by refractive index writing on the IOL, a phase shift in the IOL to compensate for the photic phenomenon.
Method and system for modifying eye tissue and intraocular lenses
A system for ophthalmic surgery includes a laser source configured to deliver an ultraviolet laser beam comprising laser pulses having a wavelength between 320 nm and 370 nm to photodecompose one or more intraocular targets within the eye with chromophore absorbance. The pulse energy, the pulse duration, and the focal spot are such that an irradiance at the focal spot is sufficient to photodecompose the one or more intraocular targets without exceeding a threshold of formation of a plasma and an associated cavitation event. An optical system operatively coupled to the laser source and configured to focus the ultraviolet laser beam to a focal spot and direct the focal spot in a pattern into the one or more intraocular targets. The optical system focuses the laser beam at a numerical aperture that provides for the focal spot to be scanned over a scan range of 6 mm to 10 mm.
INTRAOCULAR PRESSURE MEASUREMENT FOR AN EYE DOCKED TO A LASER SYSTEM
A method for measuring the intraocular pressure (IOP) of an eye docked to an ophthalmic surgical laser system via a patient interface assembly. While the eye is docked to the laser system, and as the vertical force exerted on the eye by the patient interface fluctuates as the patient breaths and moves, the amount of corneal deformation is continuously measured by an optical coherence tomography device of the laser system and the force exerted on the eye is continuously measured by force sensors integrated in the patient interface assembly. Based on the real-time force signal and real-time corneal deformation signal, a controller calculates a linear relationship between force and corneal deformation, and determines the IOP of the docked eye by comparing a slope of the linear relationship against a pre-established slope vs. IOP calibration curve. The IOP of the docked eye can be used when setting laser treatment parameters.

An apparatus (200, 200A, 200B, 200C) has central lens body (212, 212A, 212B, 212C) for providing vision correction for a patient. The lens body (212, 212A, 212B, 212C) has an initial index of refraction and is formed from at least one material configured to have a second index of refraction when subjected to a laser and/or radiation.
Intracorneal lens implantation with a cross-linked cornea
A method of intracorneal lens implantation with a cross-linked cornea is disclosed herein. The method includes forming a pocket in a cornea of an eye, applying a photosensitizer inside the pocket so that the photosensitizer permeates at least a portion of the tissue bounding the pocket, the photosensitizer facilitating cross-linking of the tissue bounding the pocket; irradiating the cornea so as to activate cross-linkers in the portion of the tissue bounding the pocket, and thereby kill cells therein; inserting a lens implant into the pocket; and applying laser energy to the lens implant in the pocket using a laser so as to correct refractive errors of the lens implant and/or the eye in a non-invasive manner. In other embodiments, a lens implant is soaked in a cross-linking solution that includes a photosensitizer prior to being inserted into the pocket in the cornea of an eye.
