A method for refilling a lens of an eye or increasing the elasticity of a lens of an eye includes removing a central portion of the lens core through the eye's cornea, a capsulorhexis in the eye's lens capsule and a gullet extending at least partially through the cortex of the lens. The lens is then refilled with a synthetic lens material. Sufficient lens core is left in place so that the synthetic material is not in contact with a lens capsule of the eye. The synthetic material used for refilling may be selected and may be formed in a shape and thickness so as to affect the refractive characteristics of the lens. An endocapsular lenticule may be inserted in the lens to affect the refractive characteristics of the lens.

A navigation apparatus for optically analyzing an inner structure of an optical element and processing that element includes a detection device and a processing device. The detection device has an aperture smaller than 0.25 and the processing device is disposed relative to the analyzed inner structure of the optical element. An apparatus for planning therapy for a human eye includes a dynamic wavefront measurement device for acquiring wavefront data, a diagnostic device for determining geometric parameters of the optical apparatus of the eye, a controller for consistent superposition of the wavefront and geometric data, and an additional controller for planning the most efficient therapeutic laser cutting paths.

A device for delivering ablative medical treatments to improve biomechanics comprising a laser for generating a beam of laser radiation used in ablative medical treatments to improve biomechanics, a housing, a controller within the housing, in communication with the laser and operable to control dosimetry of the beam of laser radiation in application to a target material, a lens operable to focus the beam of laser radiation onto a target material, and a power source operable to provide power to the laser and controller.

A method of treating a human eye, generally to correct vision, and preferably in one embodiment to increase the amplitude of accommodation of the lens. The method utilizes a laser to create a desired pattern within the lens. Various patterns for treating the eye lens are also disclosed.

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.

A treatment device for the surgical correction of defective vision in an eye. The device includes a laser apparatus controlled by a controller. The controller determines a desired correction of defective vision from measurement data of the eye to produce control data for the laser, and to control the laser to emit radiation according to the control data, such that a lenticule-shaped volume is isolated in the cornea. The controller computes a lenticule-shaped intended volume, the removal of which from the cornea leads to an actual correction of defective vision in an optical zone in the eye which differs from the desired correction more at the edge of the optical zone than at the center of the optical zone. The thickness of the lenticule-shaped intended volume is less than the thickness of a lenticule-shaped comparison volume, the removal of which would bring about the desired correction of defective vision.

This apparatus treats the lens capsule so as to increase accommodation of the eye. The treatment of the lens capsule may comprise treating a portion of the lens capsule so as to stiffen the treated portion and improve accommodation of the eye. The intermediate portion of the lens capsule may be located between an optically used central portion of the lens capsule and a peripheral portion of the lens capsule connected to zonules of the eye. The stiffened intermediate portion of the lens capsule can improve coupling of the peripheral portion of the lens capsule to the central portion of the lens capsule, such that an amount of accommodation of the optically used central portion of the lens is increased. As the force of the lens capsule to a lens disposed within the lens capsule is increased, the lens may comprise the natural lens of the eye or an artificial lens such as an accommodative IOL. The treatment of the eye to stiffen the intermediate portion may comprise application of one or more of an energy or a substance to the intermediate portion.
