A treatment device for the surgical correction of hyperopia in the eye comprising a laser device controlled by a control device. The laser device separating corneal tissue by applying laser radiation. The control device controls the laser device for emitting the laser radiation into the cornea such that a lenticule-shaped volume is isolated. Removal thereof effects the desired correction. The control device predefines the volume such that a posterior surface and an anterior surface are connected via an edge surface that has a width in projection along the visual axis that is wider than the one which a straight line in the same projection, that is perpendicular at the edge of the posterior or the anterior surface would have relative to the associated surface and connects the anterior surface to the posterior surface or to the perceived extension thereof.

The invention provides personalized laser probes for use in laser systems, wherein each laser probe includes one or more characteristics tailored to a given user to thereby improve performance of and outcome of a laser treatment procedure.

A photodynamic therapy technique for preventing damage to the fovea of the eye or another body portion of a patient is disclosed herein. In one embodiment, a treatment laser is applied to a body portion of a patient using a painting technique, the treatment laser being configured to provide paint brush-type photodynamic therapy (PPDT) using the painting technique to the body portion of the patient by emitting light of a predetermined wavelength that is absorbed by tissue of the body portion of the patient to which a photosensitizer has been applied, the body portion of the patient being afflicted by a medical condition. The application of the treatment laser to the body portion of a patient using the painting technique treats the medical condition, reduces the symptoms associated with the medical condition, and/or alleviates the medical condition.

An ophthalmic surgical laser system and method for forming a lenticule in a subject's eye using “fast-scan-slow-sweep” scanning scheme. A high frequency scanner forms a fast scan line, which is placed tangential to a parallel of latitude of the surface of the lenticule and then then moved in a slow sweep trajectory along a meridian of longitude of the surface of the lenticule in one sweep. Multiple sweeps are performed along different meridians to form the entire lenticule surface, with the orientation of the scan line rotated between successive sweeps. To generate tissue bridge free incisions without leaving laser-induced marks in the eye, a laser pulse energy between 40 nJ to 70 nJ is used, and the sweeping speed is controlled such that the scan line step (the distance between the centers of consecutive scan lines) is between 1.7 μm and 2.3 μm.

A method of forming and implanting a synthetic corneal lenslet in an eye of a patient includes the steps of: forming a synthetic lenslet from a collagen solution using a mold or a 3-D printer that are configured to form the synthetic lenslet into a predetermined shape for correcting a particular refractive error of the patient; forming a cavity for receiving the synthetic lenslet in the cornea of the eye of the patient; inserting the synthetic lenslet into the cavity of the eye; applying a photosensitizer into the cavity of the eye so that the photosensitizer permeates at least a portion of the tissue surrounding the cavity and at least a portion of the synthetic lenslet; and irradiating the cornea so as to activate cross-linkers in the synthetic lenslet and cross-linkers in the portion of the tissue surrounding the cavity, and thereby prevent an immune response.

A method and apparatus for performing ophthalmic laser surgery using a pulsed laser beam is provided. The method includes establishing an initial cutting pattern comprising a plurality of original photodisruption points, establishing an enhanced cutting pattern comprising a plurality of enhanced photodisruption points selected to decrease potential adverse effects due to patient movement and having increased density over a fixed area as compared with the plurality of original photodisruption points, and performing an ocular surgical procedure according to the enhanced cutting pattern Enhanced cutting patterns may include circular cuts around the periphery of a capsule, vertical side cuts for lens fragmentation, raster lamellar cuts, and grid lamellar cuts. Each photodisruption point in the initial cutting pattern and the enhanced cutting pattern comprises a laser target point.

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.

A laser cutting device for transparent material (23), which device is designed to focus the laser light (2) into a plurality of predetermined spots within the material (23), wherein the spots lie on a predetermined cutting line or cutting area (24) running substantially perpendicularly to the direction of incidence of the laser light (2), wherein the device comprises means for mode conversion (3) into laser light having a helical phase front (5), which means can be brought into and out of the beam path of the laser light (2).

A system for producing control data for controlling a laser so as to produce at least one cutting surface in a cornea of an eye of a patient includes a non-transitory computer readable medium having stored thereon instructions for establishing a geometry of a lenticule cut, establishing a geometry of a cap cut running substantially parallel to a surface of the cornea, establishing a geometry of an external opening cut arranged outside an optical zone of the eye of the patient, and establishing a geometry of an access cut to connect the cap cut to the external opening cut.
