Abstract: An eye implant with an optical implant region for correcting an imaging error of the eye, wherein starting with biometrically determined data of optically effective components located in front of the retina of the eye, respectively data obtained through wave front measurement, the optical implant region is adjusted for a monofocal vision with a visual acuity of at least 0.7 (70%) within a field of focus depth of at least 2 diopters.

Abstract: A tear substitute having hyaluronan has a viscoelastic flow characteristics with the zero shear viscosity being ?50 mPa·s, and the shear viscosity at 1000 s?1 being ?12 mPa·s or having hyaluronan with an intrinsic viscosity [?]>2.5 m3/kg and a concentration of <0.2% w/v. A fluid with the aforementioned specifications is used as a tear substitute. A method of producing a tear substitute comprises the use of substances for reaching a viscoelastic flow characteristics with the zero shear viscosity being 50 mPa·s, and the shear viscosity at 1000 s?1 being ?12 mPa·s. Alternatively the inventive method comprises the use of hyaluronan with an intrinsic viscosity [?]>2.5 m3/kg and a concentration of <0.2% w/v.

Abstract: An apparatus for the catalytic decomposition of H2O2 in an aqueous solution which is a contact lens care agent, wherein the catalyst is formed by a shaped body which is roughened by sand blasting and which is coated by a platinum layer 1 which is produced by sputtering.
