Systems, methods, and devices used to treat eyelids, meibomian glands, ducts, and surrounding tissue are described herein. In some embodiments, an eye treatment device is disclosed, which includes a scleral shield positionable proximate an inner surface of an eyelid, the scleral shield being made of, or coated with, an energy-absorbing material activated by a light energy, and an energy transducer positionable outside of the eyelid, the energy transducer configured to provide light energy at one or more wavelengths, including a first wavelength selected to heat the energy-absorbing material. Wherein, when the eyelid is positioned between the energy transducer and the scleral shield, the light energy from the energy transducer and the heated energy-absorbing material of the scleral shield conductively heats a target tissue region sufficiently to melt meibum within meibomian glands located within or adjacent to the target tissue region.

In certain embodiments, an ophthalmic laser surgical system for imaging and treating a target in an eye includes a laser device, imaging system, and computer. The laser device directs the focus of a laser beam towards an intended location (x0, y0, z0) of the target to yield a cavitation bubble in the vitreous. The imaging system directs imaging beams towards the target, receives the imaging beams reflected from the eye, generates an image of the cavitation bubble from the reflected imaging beams, and measures an actual location (x, y, z) of the cavitation bubble according to the image. The computer determines an error vector that describes an error between the intended location and the actual location, determines a correction vector to compensate for the error, and instructs the laser device to use the correction vector to direct the laser beam towards the target to treat the target.

A system for short pulse laser eye surgery and a short pulse laser system, in which a beam guidance device passes through a corresponding articulated arm, and through an applicator head and a microscope head of the system, which is movable in a three-dimensional volume both independently of one another as well as connected to each other. The system also includes, an easy-to-use patient interface with a one-piece contact element, a computer program product for methods of the incision guidance and sequentially operating referencing methods with patient interfaces containing markings.

An intraocular cyclophotocoagulation device having a proximal, reusable portion and a distal, disposable portion. The reusable portion includes laser treatment assembly comprising a laser diode and a collimating lens positioned a distance distal to the laser diode and configured to collimate light from the laser diode into a collimated laser beam and direct the collimated laser beam towards a distal end region of the proximal housing portion; and an imaging assembly. The disposable portion includes a laser guide extending through an elongate shaft and an aspheric lens positioned within the distal housing portion to receive the collimated laser beam from the proximal reusable portion and direct the collimated laser beam toward a proximal end of a fiberoptic of the laser guide and an illumination light guide and an illumination source positioned within the distal housing portion. Related devices, systems, and methods are provided.

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.

Apparatus (20) for ophthalmic treatment includes an optical unit (30), which includes a camera (54), which is configured to capture an image of an eye (25) of a patient, a laser (48), which is configured to emit pulses of laser radiation, and beam conditioning and scanning optics (49, 50), which are configured to focus and direct the laser radiation to impinge on an anterior surface of the eye. A controller (44) is configured to analyze the image so as to identify a limbus of the eye, and to control the optical unit so that the laser radiation impinges on a set of one or more locations on the anterior surface of the eye that are in a vicinity of the limbus with a pulse duration and an energy selected so as to stem cells at the one or more locations.

A planning device for generating control data, a treatment apparatus for refraction correction eye surgery and a method for generating control data for such a treatment apparatus which allows an improved subsequent refraction correction. The planning device includes a calculation processor for defining a cut surface of the cornea for post-treatment, wherein the calculation device is designed such that a change of thickness of the epithelium is taken into account in the calculation, which was caused essentially by a pretreatment.

The present invention relates to an optical treatment apparatus and an operating method thereof. The present invention provides an optical treatment apparatus and an operating method thereof, the optical treatment apparatus comprising: a treatment beam generation unit for generating a treatment beam; a beam delivery unit for forming a path through which the treatment beam generated from the treatment beam generation unit travels to a treatment area located in a fundus; a monitoring unit for irradiating a detecting beam along the path through which the treatment beam travels, and detecting state information on the treatment area on the basis of speckle change information of the detecting beam 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 state information on the treatment area detected by the monitoring unit.

Embodiments of the claimed invention are directed to the treatment of glaucoma (or conditions of elevated intraocular pressure) using a novel ab interno trabeculotomy procedure that uses a flexible device. At least one advantage of the present method is that it does not require a conjunctival or scleral incision, which in turn improves patient recovery time and healing.
