Abstract: A method of generating three dimensional shapes for a cornea and lens, the method including illuminating an eye with multiple sections of light and obtaining multiple sectional images of the eye based on the multiple sections of light. For each obtained multiple sectional image, the following processes are performed: a) automatically identifying arcs corresponding to anterior and posterior corneal and lens surfaces of the eye by image analysis and curve fitting of the obtained multiple sectional images; and b) determining an intersection of lines ray traced back from the identified arcs with a known position of a section of space containing the section of light that generated the obtained multiple sectional images, wherein the intersection defines a three-dimensional arc curve. The method further including reconstructing three-dimensional shapes of the cornea surfaces and the lens surfaces based on fitting the three-dimensional arc curve to a three-dimensional shape.

Abstract: 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.

Abstract: A method for providing control data for an ophthalmological laser of a treatment apparatus is disclosed. The method provides the steps of: ascertaining visual disorder correction data for correcting a cornea of an eye; determining Zernike polynomials from the ascertained visual disorder correction data; ascertaining an offset vector from a pupil center to a further preset reference center of the eye; calculating corrected Zernike polynomials, in which higher order aberrations are calculated by means of an adaptation of the corresponding Zernike polynomials by the offset vector; and providing the control data for the treatment apparatus, wherein the control data is generated by means of the corrected Zernike polynomials.

Abstract: A laser surgery system includes a light source, an eye interface device, a scanning assembly, a confocal detection assembly and preferably a confocal bypass assembly. The light source generates an electromagnetic beam. The scanning assembly scans a focal point of the electromagnetic beam to different locations within the eye. An optical path propagates the electromagnetic beam from a light source to the focal point, and also propagates a portion of the electromagnetic beam reflected from the focal point location back along at least a portion of the optical path. The optical path includes an optical element associated with a confocal detection assembly that diverts a portion of the reflected electromagnetic radiation to a sensor. The sensor generates an intensity signal indicative of intensity the electromagnetic beam reflected from the focal point location. The confocal bypass assembly reversibly diverts the electromagnetic beam along a diversion optical path around the optical element.

Abstract: An arrangement for laser treatment of vitreous floaters. The arrangement for laser vitreolysis of an eye includes an OCDR system, a laser system having a deflection unit, optical elements that couple the OCDR system and the laser system, a display unit and a central control and operating unit. The OCDR system is configured to localize the position of a floater along the optical axis of the OCDR system. The laser system is configured to destroy the floaters by application of laser pulses, and the central control and operating unit is configured to focus the laser system onto the position of the floater and to activate it, in particular when the position of the laser focus and the floater match in a sufficient manner. The present invention relates to an arrangement for the gentle, low risk and painless laser treatment of vitreous floaters, which allows a partially or fully automated therapy.

Abstract: The control unit executes an irradiation plan acquisition step and a spot interval guide display step. At the irradiation plan acquisition step, the control unit acquires an irradiation plan for irradiating a patient's eye with treatment laser light using a contact lens having a reflective surface that reflects the treatment laser light in a direction intersecting the optical axis. At the spot interval guide display step, the control unit controls the internal display unit to display a spot interval guide indicative of an appropriate interval between a plurality of irradiation spots in accordance with the progress of the irradiation plan. The plurality of irradiation spots are scheduled to be irradiated with the laser light.

Abstract: An ophthalmic treatment system and method for performing therapy on target tissue in a patient's eye. A delivery system delivers treatment light to the patient's eye and a camera captures a live image of the patient's eye. Control electronics control the delivery system, register a pre-treatment image of the patient's eye to the camera's live image (where the pre-treatment image includes a treatment template that identifies target tissue within the patient's eye), and verify whether or not the delivery system is aligned to the target tissue defined by the treatment template. The control electronics control the delivery system to project the treatment light onto the patient's eye in response to both an activation of a trigger device and the verification that the delivery system is aligned. to the target tissue, as well as adjust delivery system alignment to track eye movement.
