Disclosed are a method and a device for controlling an eye surgery system, wherein a light pattern is generated on an eye by an illumination device and is captured by a camera unit while the patient is in the position in which he or she will undergo the surgery. At least one property of the eye characterizing the current orientation of the eye during the surgery is determined from the light pattern by a computing unit.

A method of scanning a laser beam across a set of cells includes during a first interval, scanning a laser beam across a set of cells; and during a second interval, deflecting the laser beam away from the set of cells. The first interval is selected to cause microcavitation in at least a portion of the cells from the set of cells.

An apparatus, such as lenses, a system and a method for providing custom ocular aberrations that provide higher visual acuity. The apparatus, system and method include inducing rotationally symmetric aberrations along with an add power in one eye and inducing non-rotationally symmetric aberrations along with an add power in the other eye to provide improved visual acuity at an intermediate distance.

A steerable laser probe may include a handle having a handle distal end and a handle proximal end, an auto-fixing actuation control, a housing tube having a housing tube distal end and a housing tube proximal end, a first housing tube portion having a first stiffness, a second housing tube portion having a second stiffness, and an optic fiber disposed within an inner bore of the handle and the housing tube. An actuation of the auto-fixing actuation control may gradually curve the housing tube. A gradual curving of the housing tube may gradually curve the optic fiber.

Apparatuses and methods for the treatment of glaucoma are provided. The instrument uses either cauterization, a laser to ablate, sonic or ultrasonic energy to emulsify, or mechanical cutting of a portion of the trabecular meshwork. The instrument may also be provided with irrigation, aspiration, and a footplate. The footplate is used to enter Schlemm's canal, serves as a guide, and also protects Schlemm's canal.

A laser conical photoablation system in accordance with the present invention comprises a corneal measurement unit configured to measure a cornea and obtain state data of the cornea, a laser control unit configured to control an output intensity and range, an amount, and time of a laser according to a photoablation position and a photoablation shape of the cornea based on a corneal photoablation plan generated based on the state data of the cornea, and a laser module configured to irradiate the cornea with a laser according to a control signal applied by the laser control unit, wherein the state data of the cornea includes a conical surface elevation map, and the laser corneal photoablation system treats dry eye disease by performing corneal photoablation on a surface elevation deviation portion of the cornea.

An ophthalmic laser ablation system is described with various optional features, some especially suitable for non-penetrating filtration on an eye. In one example, focusing of an ablation laser uses a movable lens coupled to a pair of converging light sources, which converge at the focal distance of the lens. In another example, laser ablation settings are selected for optimal ablation and minimal amount of thermal damage of a layer of percolating scleral tissue.

Laser pulse modulation for laser corneal treatments is used to control the thermal energy imparted to the cornea. The optical energy of the laser pulses may be modulated to reduce or increase the thermal energy, depending upon an expected thermal load or a measured temperature at each position location of the cornea subject to laser treatment. The laser pulse modulation may involve pulse frequency modulation, pulse amplitude modulation, and pulse duration modulation.

An imaging probe comprises a camera or endoscope with an external detector array, in which the probe is sized and shaped for surgical placement in an eye to image the eye from an interior of the eye during treatment. The imaging probe and a treatment probe can be coupled together with a fastener or contained within a housing. The imaging probe and the treatment probe can be sized and shaped to enter the eye through an incision in the cornea and image one or more of the ciliary body band or the scleral spur. The treatment probe may comprise a treatment optical fiber or a surgical placement device to deliver an implant. A processor coupled to the detector can be configured with instructions to identify a location of one or more of the ciliary body band, the scleral spur, Schwalbe's line, or Schlemm's canal from the image.

What is proposed is an ophthalmological ultra-violet laser system for eye treatment comprising a laser source including a Ce:YAG gain medium configured to generate a pulsed primary laser beam, and a frequency converter arranged downstream from the laser source comprising one or more non-linear optical crystals configured to multiply the frequency of the primary laser beam to generate a pulsed UV laser beam.
