摘要： A method of preparing an apparatus for material processing by generating optical breakthroughs in an object. The apparatus includes a variable focus adjustment device. A contact element is mounted to the apparatus, the contact element has a curved contact surface having a previously known shape. The position of the contact surface is determined prior to processing the object, by focusing measurement laser radiation near or on the surface by the variable focus adjustment device, and the focus position is adjusted in a measurement surface intersecting the expected position of the contact surface. Radiation from the focus of the measurement laser radiation is confocally detected. The position of points of intersection between the measurement surface and the contact surface is determined from the confocally detected radiation to determine the position of the contact surface from the position of the points of intersection and the previously known shape of the contact surface.

摘要： An ophthalmic instrument for the application of laser radiation in a patient's eye, particularly for the examination and/or surgical laser treatment of the cornea and the lens of the eye, includes a femtosecond laser, an objective and optical assemblies. The optical assemblies are arranged in front of the objective, and selectively vary the focus position in the coordinate direction X,Y and Z either within the region of the cornea or within the region of the lens of the eye. The objective or at least one lens group is movable relative to the eye. The variation of the position of the lens group objective shifts the focus position from the cornea to the lens of the eye and vice versa.

摘要： A lens holder for holding a vitrectomy lens during a surgical procedure may include a support ring sized and shaped to receive a portion of the vitrectomy lens to provide visualization of a surgical site in an eye of the patient. The support ring may be configured to rest upon the eye of the patient during a surgical treatment procedure performed on the eye. The lens holder may also include a transparent, flexible membrane disposed along a bottom plane of the support ring and configured to conform to a surface feature on the eye. It may also include an overflow trough to control contact of a wetting agent with the eye.

摘要： The present invention relates to a contact lens assembly and to an ophthalmic treatment apparatus comprising same. The contact lens assembly according to the present invention comprises: a housing arranged on the cornea of an eyeball so as to guide the treatment beam radiated onto the eyeball; and a reflection unit arranged inside the housing so as to radiate the treatment beam guided to the inside of the housing to a plurality of irradiation points along the outer circumferential direction of the eyeball around the pupil of the eyeball.

摘要： Apparatus and methods are provided for interfacing an ophthalmic surgical laser with an eye using a patient interface (PI). The PI may include a closed, fluid-filled bladder having fiducials that contacts and deforms to the eye. Or, the PI may have an applanation lens with an outer ring portion and an inner concave portion for receiving the apex of the cornea. Another PI features a suction ring with a flexible skirt for contacting the sclera that is non-circular and/or non-planar. A system for injecting an index matching fluid into the area above the eye may also be incorporated. An integrated system includes a co-molded lens cone and attachment ring, with a lens window at the bottom of the lens cone which provides a sealed volume for vacuum-attaching a laser delivery system above the lens cone.

摘要： A system and method for inserting an intraocular lens in a patient's eye includes a light source for generating a light beam, a scanner for deflecting the light beam to form an enclosed treatment pattern that includes a registration feature, and a delivery system for delivering the enclosed treatment pattern to target tissue in the patient's eye to form an enclosed incision therein having the registration feature. An intraocular lens is placed within the enclosed incision, wherein the intraocular lens has a registration feature that engages with the registration feature of the enclosed incision. Alternately, the scanner can make a separate registration incision for a post that is connected to the intraocular lens via a strut member.

摘要： An ophthalmic surgical system includes a chassis comprising a laser source. The system includes a gantry coupled to the chassis. The position of the gantry is adjustable. The system includes a reference interface coupled to the gantry. The reference interface comprises an attachment interface at a distal portion of the reference interface, configured to couple to a patient interface for docking with an eye. The reference interface is configured to move to a first plate position proximal to the chassis and a second plate position distal from the chassis. The system further includes an optical head unit coupled to the reference interface. The optical head unit comprises a laser scanner and a beam splitter. The optical head unit is configured to move to a first head unit position near a proximal end of the reference interface and a second head unit position which is a lockable surgical position near a distal end of the reference interface.
