APPARATUS FOR PATTERNED PLASMA-MEDIATED LASER OPHTHALMIC SURGERY
A system for ophthalmic surgery on an eye includes: a pulsed laser which produces a treatment beam; an OCT imaging assembly capable of creating a continuous depth profile of the eye; an optical scanning system configured to position a focal zone of the treatment beam to a targeted location in three dimensions in one or more floaters in the posterior pole. The system also includes one or more controllers programmed to automatically scan tissues of the patient's eye with the imaging assembly; identify one or more boundaries of the one or more floaters based at least in part on the image data; iii. identify one or more treatment regions based upon the boundaries; and operate the optical scanning system with the pulsed laser to produce a treatment beam directed in a pattern based on the one or more treatment regions.
CONTROLLING THE TEMPERATURE OF THE CORNEA DURING OPHTHALMIC SURGERY
An ophthalmic surgical system for controlling a temperature of a cornea of an eye for a surgical procedure comprises a fluid management system and a computer. The fluid management system manages fluid within a channel structure created in the cornea of the eye. The computer instructs one or more of the controllable components to create the channel structure in the cornea. The channel structure provides a passageway between an interior of the eye and an exterior of the eye, and is proximate to a treatment site. The computer instructs the fluid management system to manage fluid within the channel structure in order to control the temperature of the cornea of the eye.
OPHTHALMIC TREATMENT DEVICE AND METHOD FOR DRIVING SAME
The present invention relates to an ophthalmic treatment device and a method for operating the same. The present invention provides an ophthalmic treatment device and a method for operating the same, the ophthalmic treatment device comprising: a treatment beam generation unit for generating a treatment beam; a beam delivery unit for forming a path along which the treatment beam generated from the treatment generation unit is delivered to a treatment area positioned on the fundus; a monitoring unit for emitting a detecting beam along the path of delivery of the treatment beam and sensing treatment area state information on the basis of information regarding a change in speckle of the detecting beam, which is scattered and reflected from the treatment area; and a control unit for controlling the driving of the treatment beam generation unit on the basis of the treatment area state information sensed by the monitoring unit.
Method for changing the perceptual color appearance of the iris of a human's or animal's eye
The underlying invention is directed to a method for changing the human perceptual color appearance of the iris of a human's or animal's eye by selectively decreasing the density of pigments of the anterior stroma layer of the iris. The method comprises generating, by a generator module, a plurality of predefined energy quantities; and applying, by the generator module, one or more of the predefined energy quantities to the anterior stroma layer, wherein each of the predefined energy quantities is generated and applied, such that the energy quantities ablate, at least in part, melanocytes of the stroma whilst leaving non-melanocyte tissue of at least the stroma essentially undamaged, and wherein the predefined energy quantities generated and applied to the anterior stroma layer in the form of pressure waves and/or pulses generated within a fluid medium that is in fluidical communication with the anterior stroma layer.
Selective photocoagulation
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.
ADJUSTING LASER ENERGY IN ACCORDANCE WITH OPTICAL DENSITY
In certain embodiments, a device comprises a laser device and a control computer. The laser device directs a laser beam with laser energy through an outer portion of an eye to a target portion of the eye. The control computer receives an optical density measurement of the outer portion, determines the laser energy according to the optical density measurement, and instructs the laser device to direct the laser beam with the laser energy through the outer portion of the eye to the target portion of the eye.
High-order optical correction during corneal laser surgery
Systems and methods related to corneal ablation for treatment of one or more high-order optical aberrations are provided. A method includes providing a defect-correcting prescription, determining an ablation profile to impose the prescription on the cornea, and determining a sequence of laser-energy ablations to impose the ablation profile on the cornea. The prescription may include a high-order optical correction. The ablation profile includes a first-segment profile and a second-segment profile. The second-segment profile corresponds to at least one high-order optical correction. The ablation sequence includes applying ablations corresponding to the first-segment profile prior to applying ablations corresponding to the second-segment profile.
Minimally Invasive Glaucoma Surgical Instrument and Method
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.
DEVICE AND METHOD FOR PRODUCING PAINT MARKS ON AN EYE
A marker device for producing paint marks on an eye is disclosed. The marker device comprises a handling unit and a marker unit coupled to the handling unit for rotation with respect to the handling unit about a rotational axis. The marker unit includes at least two spaced apart marking surfaces and has a rotationally symmetric distribution of weight with respect to the rotational axis. A coupling between the handling unit and the marker unit permits the marker unit to rotate, due to gravity, relative to the handling unit into an equilibrium position.
OPHTHALMIC LASER TREATMENT DEVICE, OPHTHALMIC LASER TREATMENT SYSTEM, AND LASER IRRADIATION PROGRAM
An ophthalmic laser treatment device includes an irradiation unit that irradiates a patient's eye with laser treatment light and a control unit that controls the irradiation unit. The control unit acquires a motion contrast acquired by an OCT unit that detects an OCT signal of measurement light reflected from the patients eye and reference light corresponding to the measurement light, acquires irradiation target information based on the motion contrast, and controls the irradiation unit so as to irradiate the patient's eye with the laser light, based on the irradiation target information.
