Abstract: The present disclosure relates to an ophthalmological patient interface for application to an eye of a person, the ophthalmological patient interface comprising a coupling portion configured to be arranged on an application head of an ophthalmological laser treatment system, wherein the ophthalmological patient interface further comprises an eye fixation portion configured to be arranged on the eye, wherein the eye fixation portion comprises a cornea contacting element, configured to contact at least partially the cornea of the eye, and a sclera contacting element, configured to contact at least partially the sclera of the eye, wherein the cornea contacting element and the sclera contacting element define a rotationally asymmetric contact surface configured to contact the eye.

Abstract: The present disclosure relates to an ophthalmological laser treatment system for treatment of tissue of an eye comprising an ophthalmological laser treatment device comprising a base station having a treatment laser source configured to generate a treatment laser beam, an arm and an application head, wherein the ophthalmological laser treatment system further comprises an ophthalmological patient interface with a cornea contacting element, and a sclera contacting element, wherein the cornea contacting element and the sclera contacting element define a rotationally asymmetric contact surface configured to contact the eye, wherein the ophthalmological patient interface comprises a through opening, which is configured to enable the treatment laser beam from the application head to pass through the ophthalmological patient interface to penetrate a target volume of tissue of the eye.

Abstract: A zipper closure including first and second rows of teeth formed on first and second bands. Each tooth has a free end in which a channel is formed. Each channel has a bottom which is convexly curved. The zipper closure includes a slider with a projection for opening and closing the zipper closure.

Abstract: A zipper closure comprises first and second rows of plastic teeth formed on first and second bands, each said band having an edge bead, said teeth having free ends and opposed back ends fixed to said bands. In said teeth close to said back ends of said teeth decorative stones are formed, each of said decorative stones having a tapered portion with a tip, said tip being directed to said respective band, and lying closer to said respective band as a tangent plane on said edge bead of said band, which tangent plane lies parallel to said band.

Abstract: A zipper closure includes teeth having decorative stones. The teeth engage each other by respective support surfaces, the extension (h) of which in the direction of the zipper closure is at most as large as the largest diameter (D) of the decorative stones.

Abstract: The invention relates to a zipper closure comprising a first and second row of teeth formed on a first and second band, each band comprising an edge bead or web, said teeth having free ends, each of which with a channel formed therein, when said zipper closure being closed said free ends of said first row of teeth extending into an area of attachment of said teeth of said second row of teeth and vice versa, whereby said channels receive said edge beads or webs, the zipper closure further comprising a slider with a top cover plate and a bottom cover plate connected by a cross-piece, said slider having a wider front end and a narrower back end, said cross-piece having a front end directed towards said wider front end of said slider and a back end directed towards said narrower back end of said slider.
