Abstract: A system for detecting position data of an element in the front region of an eye. A first system component continuously detects position changes of the vertex of the cornea of the eye. A second system component directs electromagnetic radiation at topographical structures of the cornea to be ascertained or modified. A control unit includes a processor and memory. Alignment of the first system component with respect to the alignment of the second system component is defined, and the second system component is continuously guided to the respective target position thereof, by the control unit based on the position changes detected by the first system component. Light sources, which illuminate the cornea, are symmetrically disposed around the main axis of the system so that a pattern of reflection points is created on the cornea. The processor determines the current position of the vertex as the center of the reflection points.

Abstract: It was found that water-repellent thermoplastic moulding compositions, which comprise a) from 66 to 72% by weight of one or more styrene-acrylonitrile copolymers as component A, b) from 25 to 35% by weight of one or more polyacrylate rubbers as component B, c) from 1 to 5% by weight of one or more fluorine-containing polymer components C, selected from the group of polyvinyliden-difluoride and polyvinyliden-tetrafluoride, d) from 0.05 to 6% by weight of one or more further additives, which are different from C, as component D, where each of the % by weight values is based on the total weight of components A to D and these give a total of 100% by weight, have good replication properties and lead to highly water-repellent surfaces.

Abstract: A method and apparatus including an interferometer is provided for sequentially recording interferometric sectional images at different depths, in particular for analyzing an eye. By use of an interferometer, which includes an optical reference path and an optical sample path, a sample beam scans a measuring region of a sample, in particular of an eye, so as to generate a deep sectional image. The optical and geometric paths in a sample arm and/or reference arm of the interferometer can be switched quickly between two or more positions. The path length of the sample beam and/or of the reference beam is changed by way of a path length switching unit, deep sectional images are generated at least at two different depths of the sample, and the change of the path length in the switching unit takes place by deflection of the beam paths to different geometric paths.

Abstract: A device for a therapeutic treatment of the eye by means of a laser is provided, which allows a real-time monitoring of the treatment. In particular, the laser light is supplied to the treatment region via a fibre. The monitoring of the treatment happens by means of optical coherence tomography (OCT). To this end the OCT measurement beam and the treatment laser light are coupled in a probe that is put onto the eye and allows to focus the OCT measurement beam on the tissue region inside of the eye that is treated at that moment.

Abstract: In a venous bubble trap (1), having a housing (2) to which fluid, in particular blood, can be delivered essentially tangentially via a fluid inlet (8) and from which fluid can be carried away via a fluid outlet (10), and having a filter device (3) located in the interior of the housing (2), the filter device (3) divides the housing interior into a prefilter region (5) and a postfilter region (6), and the postfilter region (6) surrounds the prefilter region (5) in at least some portions. As a result, air is reliably removed from the fluid.

Abstract: It is the case of an interferometric measuring arrangement for superimposing at least two light waves, with a first coupling means for coupling the light waves coming from a light source into a sample arm and into a reference arm, and with a second coupling means for superimposing the light waves coming from the reference arm and the sample arm, which are led to at least one detector. The light waves at least within the reference arm are exclusively led in at least one fiber guide which they do not leave on their path between the coupling means, and with which the sample arm extends on both sides of the first coupling means.

Abstract: The device serves the change of the length of the running path of an electromagnetic wave, and specifically of a light beam between the emitter and receiver. It comprises two oppositely lying reflection means between which the beam is reflected, as well as a means for changing the distance of these reflection means. The reflection means are arranged at an angle &bgr; to one another which lies between 0° and 45° so that the incident beam is thrown to and fro several times between the reflection means, until it is finally congruently thrown back.

Abstract: Systems, methods, and apparatus are provided for deriving the relative position of an eye by tracking a boundary of the eye such as the limbus (i.e., the interface between the white sclera and the colored iris). A technique for tracking the position of the eye of patient comprises directing light to an annular region of the eye between the sclera and the iris and receiving reflected light from that region. The intensity of the reflected light is then measured to determine a relative position of the eye. In some embodiments, the measured region is scanned around the boundary. In other embodiments, a light spot is scanned around a substantially annular trajectory radially outward from the pupil. The signals corresponding to the intensity of the reflected light are then processed and measured to determine the eye's position. A flap of tissue covering the boundary may be automatically detected so as to selectively measure the boundary away from the flap.
