OPHTHALMIC APPARATUS, METHOD OF CONTROLLING OPHTHALMIC APPARATUS, AND RECORDING MEDIUM
An ophthalmic apparatus includes an interference optical system, an optical scanner controller, and a correction controller. The interference optical system includes an astigmatism correction optical member and an optical scanner, and is configured to split light from a light source into reference light and measurement light, to irradiate the measurement light onto the subject’s eye via the astigmatism correction optical member and the optical scanner, and to detect interference light between returning light of the measurement light from the subject’s eye and the reference light. The optical scanner controller is configured to control the optical scanner so as to deflect the measurement light in a horizontal direction and a vertical direction on a plane perpendicular to an optical axis of the interference optical system. The correction controller is configured to control the astigmatism correction optical member so as to correct astigmatism based on a detection result of the interference light obtained by the interference optical system.
Second pass femtosecond laser for incomplete laser full or partial thickness corneal incisions
A method for forming an incision in an eye, the method including performing a first pass of a first laser beam along a path within an eye, wherein after completion of the first pass there exists a residual uncut layer at an anterior surface of a cornea of the eye. The method further including performing a second pass of a second laser beam only along a portion of the path that contains the residual uncut layer, wherein after completion of the second pass, the residual uncut layer is transformed into a full complete through surface incision.
Fundus alignment in optical treatment systems
a laser-based ophthalmological treatment system(200) may include a device housing(202), a head fixation assembly(206), and an interactive display device(324, 424). The head fixation assembly(206) may be configured to position and to retain a head of a patient relative to the device housing(202). The interactive display device(324,424) may be positioned in an optical path(304,404). The interactive display device(324,424) may be fixed relative to the head fixation assembly(206). The interactive display device(324,424) may be configured to display a simulation scene(504) that may include a target image(502) into a visual field of the patient. The target image(502) may be displayed in the simulation scene(504) such that optical focus on the target image(502) by the patient aligns a portion of a fundus(130) of an eye of the patient in the optical path(304,404).

METHOD FOR PROVIDING CONTROL DATA OF AN EYE SURGICAL LASER OF A TREATMENT APPARATUS BASED ON A PATIENT-SPECIFIC PARAMETER SET; CONTROL DEVICE AS WELL AS TREATMENT APPARATUS
A method for providing control data of an eye surgical laser of a treatment apparatus is disclosed for a treatment on a human or animal eye. The method optimizes a target conflict between low stress for a patient and efficacy of a laser. The method includes, as performed by a control device, determining a patient-specific parameter set, which relates to at least one physiological characteristic of the eye, determining at least one physical parameter for the eye surgical laser depending on the patient-specific parameter set, wherein the physical parameter relates to a physical characteristic of a laser beam of the laser, and providing control data for controlling the eye surgical laser, which includes the physical parameter.
METHOD AND SYSTEM FOR ADJUSTING THE REFRACTIVE POWER OF AN IMPLANTED INTRAOCULAR LENS
A method for adjusting the refractive power of a fluid-filled intraocular lens implanted into a patients eye. The method comprises selecting a pattern to cause a flattening of the intraocular lens or an increase in curvature of the intraocular lens, and ablating the pattern, onto either an optical element of the intraocular lens or a flexible element of the intraocular lens, to alter either one or both of a refractive power and an amplitude of accommodation of the intraocular lens. The ablating occurs while the intraocular lens remains implanted in the patient's eye. The ablating maintains the integrity of a fluid-filled interior cavity defined between the optical element and the flexible element, but causes the flattening of the intraocular lens or the increase in curvature of the intraocular lens.
SYSTEM FOR LASER PHOTOCOAGULATION OF THE RETINA
The invention relates to a system for laser photocoagulation of the retina, comprising: a photocoagulation laser (1); an optical path (5) connecting the upstream photocoagulation laser (1) to a downstream laser outlet opening (6) intended to be positioned in front of the retina; an adaptive optical element (9) positioned in the optical path and configured to modify the wavefront of the laser beam being propagated in the optical path, in order to compensate for aberrations of the eye that occur as far as the retina; a position control loop (10) controlling a first actuator (14) positioned in the optical path downstream of the adaptive optical element in order to control the position of the laser outlet opening relative to the retina to be treated; and at least one imaging device (8) configured to obtain an image of the retina diverted from the optical path.
