The method comprises a) providing a fixation light (20) through the contact lens (16) so that the patient's eye (12) is aligned relative to the contact lens (16) by fixing on the fixation light (20); b) detecting an image of a light pattern (24) provided by a light source with a fixed location relative to the contact lens, wherein the light pattern (24) is imaged via a reflection on the surface of the eye (12); c) presenting the image of the light pattern (24) over the eye (12) by means of the contact lens (16) with overlaying of virtual markings (26), wherein a first marking of the virtual markings (26, 26a, 26b) identifies the central axis (200) of the contact lens (16) and a second marking of the virtual markings (26, 26a, 26b) identifies a reference marking, which is derived from the image of the light pattern as lying on the central axis of the contact lens (16); d) laterally positioning the contact lens (16) relative to the eye (12) in such a manner that a distance between the first and the second marking is minimized; and e) establishing the position of the eye (12) at which the second marking is located when the first marking and the second marking adopt the minimized distance from one another as the position of the vertex (22) of the eye (12) and registering the position of the vertex (22) with the help of a feature of the eye (12) detectable in the image of the eye (12). The invention further relates to a refractive surgical laser system (10).
The invention relates to a plunger (1) for an injector (17) which is designed to inject an intraocular lens (22) into the capsular bag of an eye. The plunger (1) has a deformable cushion (2), which has an non-squeezed state and a squeezed state and which has, at a longitudinal end of the plunger, a contact surface (15), in which contact surface a cutout (6) is formed. In the non-squeezed state, the contact surface has an outer contour (7) delimiting the contact surface at the outside of the contact surface and an inner contour (10) delimiting the cutout at the outside of the cutout. An imaginary reference point (9) is arranged in the cutout, which reference point is the center point of an imaginary circle (8) arranged in the plane of the contact surface or is the center point of another closed curve. The plunger has at least two points groups, each of which has a design point (11) arranged on the outer contour, an inner contour point (13) arranged on the inner contour, and the reference point. For each of the point groups, the distance (12) from the design point to the circle or to the closed curve is equal to the distance (14) from the inner contour point to the reference point; the design point, the inner contour point and the reference point lie on a straight line; and the inner contour point lines between the design point and the reference point. The distance from the inner contour point to the reference point is different for at least two of the point groups.
The assembly for laser treatment of ocular opacities consists of: a measurement system for obtaining depth information regarding ocular structures; a laser system; an eye-tracker unit; a display unit; and a control-and-operating unit. According to the invention, the control-and-operating unit is designed to determine, from the depth profiles, the depth of ocular structures relative to the depth of the laser focus, and, in particular for the retina and the capsular bag, to determine a blocked zone for the laser treatment. Furthermore, the control-and-operating unit is designed to generate, at least for the blocked zones of the retina and capsular bag and the laser focus, at least one tag in each case, the characteristic of which corresponds to the particular depth in the eye, in order to display these tags on the display unit and to overlay them with the live image. The invention relates to a partially automated therapy apparatus for laser treatment of ocular opacities in which two-dimensional views of the eye are combined with three-dimensional imaging from the measurement system.

The present invention relates to a device for positioning an implant in an eye, more particularly for glaucoma treatment by draining aqueous humour from the anterior chamber. The device consists of an image recording unit, an image display unit, a control and evaluation unit and an implantation tool. The target areas here are the anterior chamber, the suprachoroidal space, the subconjunctival space, the trabecular meshwork, Schlemm's channel, and also the cornea and the limbus. According to the invention, the image recording unit is designed to provide preoperative and/or intra-operative images of the target area. The control and evaluation device is designed to detect important structures of the eye in the images of the target area, to propose or to select a target region for the implant and to generate navigation data for the introduction of the implantation tool into the target region. Although the proposed device is preferably intended for the implantation of stent implants in the suprachoroidal space, it can also be used for positioning implants in other regions of the eye.
