A system for forming a corneal implant includes a cutting apparatus, which includes a laser source that emits a laser and optical elements that direct the laser. The system includes a controller implemented with at least one processor and at least one data storage device. The controller generates a sculpting plan for modifying a first shape of a lenticule formed from corneal tissue and achieving a second shape for the lenticule to produce a corneal implant with a refractive profile to reshape a recipient eye. The sculpting plan is determined from measurements relating to the lenticule having the first shape and information relating to a refractive profile for a corneal implant. The controller controls the cutting apparatus to direct, via the one or more optical elements, the laser from the laser source to sculpt the lenticule according to the sculpting plan to produce the corneal implant with the refractive profile.

In certain embodiments, a system for performing refractive treatment of an eye comprises a laser, a printer, and a computer. The laser emits a laser beam to prepare the eye for the refractive treatment. The printer prints material onto a print area of a target. The printer comprises a printer head and a printer controller. The printer head directs the material onto the print area, and the printer controller moves the printer head to direct the material onto a specific location of the print area. The computer comprises a memory and processors. The memory stores instructions for a pattern for the target. The pattern is designed to provide the refractive treatment for the eye. The processors instruct the printer controller to move the printer head to print the material onto the print area according to the pattern.

Systems and methods for improving vision of a subject implanted with an intraocular lens (IOL). In some embodiments, a method of treating an ocular disease of a subject having an implanted intraocular lens (IOL) includes determining visual needs of a subject that are associated with an ocular disease of the subject determining a pattern of a plurality of pulses of radiation to apply, by refractive index writing, and applying the plurality of pulses of radiation to the one or more selected areas of the IOL.

Methods and systems for performing laser-assisted surgery on an eye form one or more small anchoring capsulotomies in the lens capsule of the eye. The one or more anchoring capsulotomies are configured to accommodate corresponding anchoring features of an intraocular lens and/or to accommodate one or more drug-eluting members. A method for performing laser-assisted eye surgery on an eye having a lens capsule includes forming an anchoring capsulotomy in the lens capsule and coupling an anchoring feature of the intraocular lens with the anchoring capsulotomy. The anchoring capsulotomy is formed by using a laser to incise the lens capsule. The anchoring feature can protrude transverse to a surface of the intraocular lens that interfaces with the lens capsule adjacent to the anchoring capsulotomy.

An apparatus for microdisruption of cataracts in lens tissue by impulsive heat deposition comprising: a source of pulsed laser radiation, a user input device, a control circuit, and an optical waveguide configured to transmit the pulsed laser radiation. The light intensity which exits the optical waveguide has a wavelength selected to match an absorption peak of at least one component of the lens tissue, a pulse duration time shorter than a time required for thermal diffusion out of the laser irradiation volume and shorter than a time required for a thermally driven expansion of the laser irradiated volume, and a pulse energy resulting in a peak intensity of each laser pulse below a threshold for ionization-driven ablation to occur.

System and method for making incisions in eye tissue at different depths. The system and method focuses light, possibly in a pattern, at various focal points which are at various depths within the eye tissue. A segmented lens can be used to create multiple focal points simultaneously. Optimal incisions can be achieved by sequentially or simultaneously focusing lights at different depths, creating an expanded column of plasma, and creating a beam with an elongated waist.

A device for altering an optical and/or mechanical property of a lens that is implanted in an eye, the device including a laser device, which has a laser beam source that provides a pulsed laser beam and an optical unit, which impinges on the implanted lens with the pulsed laser beam. The device also includes a control device, which controls the laser device such that the optical and/or mechanical property of the lens is altered on the basis of non-linear interaction between the laser beam and the lens material.

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.
