Abstract: The present disclosure provides a femtosecond laser docking apparatus that includes a suction cone, with an upper frusto-conical portion and lower spherical portion, and a suction ring, with a mechanical stop and at least one contact and sealing surface. The mechanical stop engages the spherical portion of the suction cone to prevent it from being lowered further toward an eye, in a z-direction, beyond the mechanical stop. This disclosure provides a system for femtosecond laser ophthalmic surgery that includes a suction cone, with an upper frusto-conical portion and lower spherical portion, and a suction ring. This disclosure further provides a method for docking a femtosecond laser that includes positioning a suction ring on an eye, lowering a suction cone toward the eye until it engages the mechanical stop of the suction ring, and applying suction to seal the suction cone to the suction ring by a contact and sealing surface.

Abstract: A patient adapter for an eye laser apparatus comprises a first partial adapter unit, including a suction ring portion to be placed on an eye and affixed on the eye by means of suction force, the suction ring portion having a ring axis; and a second partial adapter unit formed separately from the first partial adapter unit, the second partial adapter unit being configured for releasable coupling to the eye laser apparatus and including an eye contact element for shaping the surface of the eye, wherein the two partial adapter units are held together mechanically in a module between a first relative position, in which the eye contact element has a first axial position with respect to the suction ring portion, and a second relative position, in which the eye contact element has a second axial position with respect to the suction ring portion.

Abstract: An apparatus for laser assisted eye treatment comprises: a laser device configured to provide focused laser radiation and having an adapter coupling port; an adapter module including first and second sub-modules, the first sub-module configured to detachably couple to the laser device at the adapter coupling port and having a contact surface for an eye, the second sub-module including an eye suction ring portion having a ring axis, wherein the second sub-module delimits at least one suction space, and the adapter module includes a vacuum inlet port in association with each of the at least one suction chamber, wherein the adapter module includes an evacuation path system configured to establish a vacuum communication connection between each of the at least one suction space and the associated vacuum inlet port, wherein the vacuum inlet port is provided at the first sub-module and the evacuation path system extends from the first sub-module to the second sub-module.

Abstract: A cutting blade holder (10) for a microsurgical cutting arrangement, in particular a cutting arrangement for refractive eye surgery, comprises a receptacle (34) into which a cutting blade unit (14) together with a cutting blade (12) can be inserted. For the sideways guidance of the cutting blade unit in the receptacle the cutting blade holder comprises guide means, which in one embodiment include a plurality of guide bars (50, 52, 54, 56) arranged on both sides of the plane of the blade of the cutting blade, by means of which a relatively friction-free linear contact with the cutting blade is produced.

Abstract: A surgical cutting instrument for refractive opthalmological treatments includes an instrument base body unit (12) to be placed on the eye and that can be fixed relative to the latter, wherein guide holding means (30, 44) are associated with the instrument base body unit, the said means being intended and designed for the movably guided holding, relative to the instrument base body unit, of at least two cutting units (14) of different cutting geometries.
