An optical system for a laser therapy instrument for the application of laser radiation on and in the eye, includes a femtosecond laser, an objective. The objective or at least one lens or lens group of the objective is shiftable in the direction of the optical axis being intended for shifting of the focus position from the region of the cornea to the region of the crystalline lens and vice versa. The optical system may include at least two optical assemblies designed for the axial variation of the focus of the therapeutic laser radiation, with the focus variation range z differing between the individual assemblies and a changing device, designed for the insertion of any one of these assemblies into the therapeutic laser beam path at a time.

A method for cataract surgery on an eye of a patient includes scanning a first focus position of a first pulsed laser beam at a first pulse energy in a first scanning pattern to photodisrupt a tissue structure of a lens with a plurality of pulses of the first laser beam to form one or more cuts within the lens, the cuts being short of reaching a side edge of the lens and being configured to divide the lens into two or more segments which are attached to each other in regions adjacent the side edge of the lens; and afterwards, completely separating the two or more segments of the lens from each other by scanning a second focus position of a second pulsed laser beam having a second pulse energy higher than the first pulse energy in a second scanning pattern that is co-registered to the first scanning pattern.

The present disclosure provides a system and method for managing patient data during ophthalmic surgery. The systems and methods include an ophthalmic surgical device operable to receive data from a RFID chip. Data from the RFID chip is transmitted to a RFID read-write module operably coupled to the ophthalmic surgical system. A processor identifies the RFID chip based on the received data and determines whether the data stored to the RFID chip varies from data received from a surgical microscope by more than a predetermined percentage. The processor can generate a warning when the data stored to the RFID chip varies from data received from a surgical microscope by more than a predetermined percentage.

An exemplary surgical device includes an element positionable within a shaft having a lumen defined therethrough with the element movable from a stored position to a deployed position in which a larger portion of the element extends out of the distal end of the lumen. The element forming a closed loop which is positioned around the lens while the lens is within a capsular bag. The closed loop is reduced in size to form a cut in the lens.

A system for corneal treatment includes a light source that activates cross-linking in at least one selected region of a cornea treated with a cross-linking agent. The light source delivers photoactivating light to the at least one selected region of the cornea according to a set of parameters. The system includes a controller that receives input relating to the cross-linking agent and the set of parameters. The controller includes computer-readable storage media storing: (A) program instructions for determining cross-linking resulting from reactions involving ROS including at least peroxides, superoxides, and hydroxyl radicals, and (B) program instructions for determining cross-linking from reactions not involving oxygen. The controller executes the program instructions to output a calculated amount of cross-linking in the at least one selected region of the cornea. In response to the calculated amount of cross-linking, the light source adjusts at least one value in the set of parameters.

A device for visualizing an irido-corneal angle of an eye through a window of a patient interface configured to be placed on the eye includes and optics structure and at least one imaging apparatus. The optics structure is configured to engage with the patient interface to provide a line of sight through the window in the direction of the irido-corneal angle, and to subsequently disengage from the patient interface. The imaging apparatus is associated with the optics structure and aligned with the line of sight to enable capturing an image of the eye including the irido-corneal angle.

A laser surgical method for performing a corneal incision while maintaining iris exposure below a predetermined exposure limit includes: determining an initial iris exposure based on an initial treatment scan, determining whether the initial iris exposure is less than the predetermined exposure limit; generating a revised treatment scan comprising one or more treatment scan modifying elements when the initial iris exposure is greater than the predetermined exposure limit, and scanning the focal zone of a pulsed laser beam according to the revised treatment scan, thereby performing the corneal incision, wherein the one or more treatment scan modifying elements causes the iris exposure to be smaller than the predetermined exposure limit.

An ophthalmic surgery laser system and method of laser delivery for an ophthalmic surgery laser system are disclosed herein. Embodiments of the system and method are directed to an ophthalmic surgery laser system including a laser engine, a laser guide, and a laser shaper. Embodiments of the system and method are directed to a laser delivery system for an ophthalmic surgery laser system. Embodiments of the system and method are directed to an ophthalmic surgery laser system including additional functionality such as laser scanning confocal microscopy, 3D laser scanning, and laser beam diagnostics. Embodiments further include the use of a lower power illumination source.

A method is disclosed for adapting treatment coordinates for a treatment of an eye with an ophthalmological laser of a treatment apparatus. The treatment apparatus includes a contact element for fixing the eye. The method includes acquiring at least a first image of the eye, before the eye is fixed by the contact element, and determining treatment coordinates of the eye by means of the first image, determining orientation points of the eye and the position thereof in the first image; acquiring a second image of the eye, after the eye has been fixed by the contact element, wherein the position of the respective orientation points is determined in the second image. The method also includes determining a transformation matrix based on the respectively determined positions of related orientation points in the first and the second image, and adapting (S18) the treatment coordinates by the determined transformation matrix.

A therapeutic laser for use in treating ophthalmological conditions can be modulated by a spatial light modulation device in order to focus the therapeutic laser on a plurality of target locations simultaneously.
