  • Patent number: 11730626
    Abstract: A method is disclosed for providing control data for an eye surgical laser of a treatment apparatus for the removal of a tissue. The method includes using a control device for determining a wavefront of a cornea and Zernike polynomials from the wavefront and calculating a respective tissue geometry for each Zernike polynomial. A combination of Zernike polynomials describes a tissue removal geometry. The control device ascertains a subgroup of the Zernike polynomials by an optimization calculation, which uses a preset condition to select Zernike polynomials. The condition is preset by a maximized target corneal geometry and a target imaging correction to be achieved. The target corneal geometry is a difference between a corneal geometry and the tissue removal geometry. An optimized tissue removal geometry is found using the subgroup and control data for controlling the eye surgical laser, which uses the optimized tissue removal geometry for separating the tissue.

  • Patent number: 8992013
    Abstract: Embodiments of the invention pertain to a method for producing a spectacle lens with optimal correction across the entire lens taking into account the patient's complete measured wavefront. Specific embodiments can also take into account one or more additional factors such as vertex distance, segmental fitting height, pantoscopic tilt, and use conditions. The lens wavefront can be achieved by optimizing a corrected wavefront, where the corrected wavefront is the combined effect of the patient's measured wavefront and the lens wavefront. The optimization of the corrected wavefront can involve representing the measured wavefront and the lens wavefront on a grid. In an embodiment, the grid can lie in a plane. During the optimization, a subset of the grid can be used for the representation of the measured wavefront at a point on the grid so as to take into account the portions of the measured wavefront that contribute to the corrected wavefront at that point on the grid.

    Abstract: A hydrophilizingly coated silicone contact lens has a radial cross-section of the inner face (1), the rim portion contour of which is convex (7) between a point of inflection (6) and the outer edge. For its manufacture, a silicone precursor is brought between a female and a male mold and is polymerized, and the polymerized contact lens is released from the mold by means of a liquid swelling same and is completed after a PECVD/CVD-coating without edge cutting.

  • Patent number: 8936362
    Abstract: The present invention is directed to a non-deforming contact lens for keratoconus patients having a displaced central zone. In particular, the central zone is displaced from the geometric center of the lens. The shape of the central zone is egg or spoon-shaped and is rotationally asymmetrical with one semi-meridian that is shorter than a corresponding semi-meridian. An intermediate transition zone is formed integral with the periphery of the central zone, and a peripheral zone is formed integral with the periphery of the intermediate transition zone, forming a round contact lens.

  • Patent number: 8931899
    Abstract: A method for trimming an ophthalmic lens using a machining device having a load sensor for measuring a load relating to the load applied by a machine tool to the lens, includes: immobilizing the lens on an immobilizing element, and trimming the lens, while measuring the load magnitude and steering the machine tool relative to the immobilizing element so as to bring the initial contour of the ophthalmic lens to a final contour of a different shape. Between the immobilizing and trimming steps, the machine tool is steered relative to the immobilizing element so that it makes a tour around the lens without contact therewith, while measuring the unladen load magnitude, this relating to the load required to move the machine tool relative to the immobilizing element without performing machining work while steering the machine tool, during the trimming step, as a function of the unladen magnitude measured.

  • Patent number: 8911083
    Abstract: A system for facilitating contact lens design comprises an input unit for input of design parameters, and a processing unit for calculating a post-lens pressure profile based on the design parameters. The processing unit is arranged, in use, to perform a finite model calculation allowing for large deflection and non-linear geometry effects in the deformation of a model lens shape. Preferably the finite element model calculation utilizes solid elements of modelling the lens shape. A contact comprising a high Young's modulus material such as silicone hydrogel can be designed to have a maximum corneal or limbal post-lens pressure valve of less than 250 Pa.
