An ultraviolet laser-based (UVL) laser vision correction (LVC) system, a contact interface and a contact interface system for such a UVL-LVC system. The invention facilitates a coupling and affixation between the patient's eye and the UVL-LVC system by application of a contact interface for the purposes of preventing eye movements when using UVL-LVC systems. The invention includes a UVL-LVC system with a base unit and an application arm which has a contact interface adapter on an application part of the application arm, to which a contact interface is affixable, the contact interface being usable to be to affix a patient's eye to the UVL-LVC system. The contact interface may have a conical wall and a suction ring but not a lens element, and optionally has an access opening or a corresponding contact interface system made of a contact interface adapter and a contact interface.

An arrangement for the sterile handling of a non-sterile endoscope in a sterile environment comprises a sterile endoscope sheath for accommodating the endoscope and a cable via which the endoscope is connectable to a control unit, the arrangement further comprising a sterile cable sheath for accommodating at least a portion of the cable, wherein the endoscope sheath comprises a first sterile lock comprising at least one first sterile flap which in the closed state shields the endoscope arranged in the endoscope sheath in a sterile manner. The cable sheath comprises a second sterile lock having a second sterile flap which in a closed state shields the cable arranged in the cable sheath and/or a plug connector present on the arranged cable in a sterile manner. When connecting the cable or the plug connector to the endoscope, a movement of the first sterile flap from the closed state into an open state takes place and a movement of the second sterile flap from the closed state into an open state takes place so that a direct coupling of the cable to the endoscope or of the plug connector connected to the cable to a complementary plug connector of the endoscope is possible.

A method for performing a corneal ablation procedure on an eye of a patient including determining a refractive correction for the eye and determining a first parameter corresponding to the refractive correction or a condition of the patient. An ablation profile is selected that includes a refractive correction component and a pre-compensating component that is selected based on the first parameter. The ablation profile is configured to promote a controlled induction of a higher order aberration, where the pre-compensating component limits the induction of the higher order aberration to be within a predefined range. The cornea is ablated using the selected ablation profile.

An ophthalmological laser system and operating method wherein laser-supported operative interventions can be achieved with higher accuracy. The cornea is irradiated with an ophthalmological laser and a detection light confocally recorded, the cornea being scanned in three-dimensions by irradiation with an illuminating laser power using a scanner unit along several directions at several points. Using the simultaneously recorded detection light the position and/or shape of a posterior boundary surface of the cornea is determined. A lamella parallel to the posterior boundary surface can then be cut.

A method and a device for forming cut surfaces in a transparent material, particularly in the cornea, by producing optical breakthroughs in the material by application of laser radiation focused into the material. The focal point is adjusted in three dimensions to form the cut surface by the sequential arrangement of optical perforations. The focal point is guided in such a manner that cutting is divided into at least two steps, and in at least one of the steps, the formation of the cut is carried out with a path radius that decreases in size, and in one of the steps, the cut formation is carried out with a path radius that increases in size.

A method of performing refractive laser eye surgery on a human eye is provided wherein the ablation pattern is centered along the visual axis, rather than along the line of sight. First, a wavefront, either ocular, corneal or a combination thereof, is generated by a wavefront sensor centered along the line of sight. This measured wavefront is centered on and encompasses a patient's pupil. Then, an analysis pupil is determined which encompasses the measured pupil. The analysis pupil is centered along the visual axis at the point of intersection with the cornea. Consequently, the measured wavefront is reconstructed over the analysis pupil only using data taken over the area covered by the measured pupil. This reconstruction is done through a least squares fit of a series of slopes from the measured wavefront and/or through the transformation of aberration coefficients. Finally, an ablation pattern, or a lenticule generation pattern, to be performed by a refractive laser centered on the corneal intersect of the visual axis is produced in accordance with the reconstructed wavefront.

A method for controlling a device for the treatment or refractive correction of the human eye using an electronic data processing system provides a simple overview of the influence of all of the parameters. To this end, once the operating parameters have been determined, a graphical simulation of the operating procedure is carried out in the form of a graphical visualization.

The invention relates to a method for determining an actual value of at least one system parameter or a deviation from a set value of at least one parameter of a system for the treatment of an eye using a treatment laser beam emitted by said system. According to the invention, the surface of a calibrating body is ablated with at least a partial beam of the treatment laser beam with a predetermined ablation program. The surface ablated by the treatment laser beam is examined by means of aberrometry and/or profilometry. The actual value of the system parameter or the deviation from the set value of the system parameter is determined on the basis of the examination data detected during the examination.

A method for measuring the dynamic behavior of an optical system is aimed at rendering the dynamic behavior of the optical system objectively detectable. To this end, the optical system to be measured is stimulated by stimuli whereby causing it to react, and the reaction is detected by means of a wave front analysis.
