摘要： System and method for generating patterns P of aiming and treatment light on target eye tissue (e.g. the retina) of a patient's eye. The system includes light sources for treatment and aiming light, a scanner for generating patterns of spots of the generated light, a controller, and a graphic user interface that allows the user to select one of several possible spot patterns, adjust the spot density and/or spot size, and apply patterns with fixed or varied density. The patterns can be formed of interlaced sub-patterns and/or scanned without adjacent spots being consecutively formed to reduce localized heating. Partially or fully enclosed exclusion zones within the patterns protect sensitive target tissue from exposure to the light.

摘要： A treatment method and apparatus for surgical correction of defective-eyesight in an eye of a patient, wherein a laser device is controlled by a control device, said laser device separating corneal tissue by irradiation of laser radiation to isolate a volume located within a cornea, wherein the control device controls the laser device to focus the laser radiation, by providing target points located within the cornea, into the cornea, wherein the control device, when providing the target points, allows for focus position errors which lead to a deviation between the predetermined position and the actual position of the target points when focusing the laser radiation, by pre-offsets depending on the positions of the respective target points to compensate for said focus position errors.

摘要： Safety of ophthalmologic laser treatment is improved. A laser treatment apparatus of an embodiment includes: a photographing system that photographs an eye; an irradiation system that irradiates aiming light of a preset pattern and treatment laser light onto a fundus of the eye; an irradiation-pattern determining part that determines an irradiation pattern of the treatment laser light based on a photograph image of the eye acquired by the photographing system and the preset pattern; and a controller that controls the irradiation system so as to irradiate the treatment laser light of the determined irradiation pattern.

摘要： An integral laser imaging and treatment apparatus, and associated systems and methods that allow a physician (e.g., a surgeon) to perform laser surgical procedures on an eye structure or a body surface with an integral laser imaging and treatment apparatus disposed at a first (i.e. local) location from a control system disposed at a second (i.e. remote) location, e.g., a physician's office. In some embodiments, communication between the integral laser imaging and treatment apparatus and control system is achieved via the Internet®. Also, in some embodiments, the laser imaging and treatment apparatus is further configured to provide photodynamic therapy to a patient.

摘要： A method of determining control parameters of a retinal treatment system comprising acquiring an image of a retina of a subject's eye using an imaging laser and an optical system of the retinal treatment system, presenting an image of the retina to a user of the retinal treatment system, receiving from the user location data of the retinal image that locates at least one treatment site of the retina, receiving from the user a required laser light pattern for use on the treatment site, using the location data to determine a location control parameter which causes the optical system to direct laser light from a treatment laser of the retinal treatment system to the treatment site, and using the required laser light pattern to determine a pattern control parameter which causes the treatment laser to produce a laser light pattern which passes through the optical system and results in the required laser light pattern at the treatment site.

摘要： System and method for making incisions in eye tissue at different depths. The system and method focuses light, possibly in a pattern, at various focal points which are at various depths within the eye tissue. A segmented lens can be used to create multiple focal points simultaneously. Optimal incisions can be achieved by sequentially or simultaneously focusing lights at different depths, creating an expanded column of plasma, and creating a beam with an elongated waist.

摘要： A system for forming a corneal implant includes a cutting apparatus, which includes a laser source that emits a laser and optical elements that direct the laser. The system includes a controller implemented with at least one processor and at least one data storage device. The controller generates a sculpting plan for modifying a first shape of a lenticule formed from corneal tissue and achieving a second shape for the lenticule to produce a corneal implant with a refractive profile to reshape a recipient eye. The sculpting plan is determined from measurements relating to the lenticule having the first shape and information relating to a refractive profile for a corneal implant. The controller controls the cutting apparatus to direct, via the one or more optical elements, the laser from the laser source to sculpt the lenticule according to the sculpting plan to produce the corneal implant with the refractive profile.
