  • Publication number: 20230218441
    Abstract: The present invention relates to a stent implant for treating glaucoma by means of intraocular fluid drainage from the anterior chamber, preferably in the suprachoroidal space. The stent implant according to the invention is designed to bring about a change in shape after being inserted into the eye, during which change the width and/or thickness or the flow cross-section is increased by more than 20%, preferably more than 200%, and particularly preferably by more than 400%, at at least one point of the stent implant. In the case of intraocular fluid drainage from the anterior chamber into the suprachoroidal space, a cyclodialysis cleft which may open can therefore be at least largely or completely closed. The proposed stent implant is provided in particular for intraocular fluid drainage into the suprachoroidal space.

  • Patent number: 10893799
    Abstract: A method for determining the topography of the cornea of an eye on the basis of an optical, contactless data capture. In the method for determining the topography of the cornea of an eye, which is based on a deflectometric method, the deflectometric measurements are carried out with the aid of a keratometric method by virtue of additional OCT-based scans being made at the keratometric measurement points, wherein the two measurement systems are registered to one another and both the keratometric and the OCT-based measurement values are recorded and used for mutual calibration to determine and output the topographic data. The proposed method serves to determine the topography of the cornea of an eye. It is helpful to ascertain the topography in order to be able to draw conclusions about possible pathological changes. Moreover, the exact measurement of the corneal topography is of great importance for correcting refractive errors.

  • Patent number: 10517761
    Abstract: Systems and methods for localizing intraocular lens and/or existing refractive index patterns, to laser write-patterns, and to refractive index patterns in order to modify the refractive index by application of femtosecond laser pulses. OCT-based confocal detection and sectional image systems are provided for localization purposes, the systems being particularly suitable for the detection of phase patterns in addition to the localization of the IOL. With respect to laser write-patterns, the modification of existing refractive index patterns in the IOL is carried out by destroying existing structures or supplementing existing refractive index patterns.

  • Patent number: 10039634
    Abstract: An intraocular lens provided for implantation into an eye, includes a lens body having a central region, haptics for holding the intraocular lens in place within the eye after implantation, and an activatable zone outside the central region. After implantation of the intraocular lens into the eye, the lens body is deformed in the central region and/or at least one of the position, the rotation or the tilt of the intraocular lens within the eye changes upon irradiating only the activatable zone with laser radiation.

  • Patent number: 9872617
    Abstract: A fundus camera with an OCT measurement module, in which, after the focusing objective, a mirror switches the light to be detected either to the OCT measurement module or an image detector. This design also renders it possible to carry out a method for improved focusing in order to improve the recording quality of the individual modalities. Furthermore, the multimodal measuring instrument distinguishes itself by an operating concept according to the invention. Such combination instruments are advantageous in that, as a result of the reduction from two instruments to one, less space is required than in the case of two separate instruments. Furthermore, reseating of the patient is avoided if recordings or measurements of different modalities should be made for one and the same patient, as a result of which the procedures in the medical practices and clinics can be influenced positively.

  • Patent number: 9560958
    Abstract: Selection of an appropriate intraocular lens (IOL) and/or the applicable surgical parameters for optimizing the results of refractive procedures on the eye. Features of the IOL are crucial for the selection and/or adjustment of the optimal IOL, but so is the IOL selection method (and parameters) from a surgical perspective. For the method, corresponding output parameters are determined from predetermined, estimated, or measured input parameters and/or their mean values, wherein at least two input parameters are varied with one another and which have at least one input parameter as a distribution function. The resulting function is optimized by means of corresponding target values and the determined distribution function of one or more output parameters is used as a decision aid. The present solution is used for selecting an appropriate IOL and/or the applicable surgical parameters and is applicable in the field of eye surgery for implanting IOLs.

  • Patent number: 9364144
    Abstract: The eye is illuminated by a variable laser light source with a measurement range corresponding to the eye length, wherein the focus of the laser beam in the eye can be shifted laterally and/or axially by an adjustment mechanism, and the light fractions back-scattered from the sample are captured via an interferometer by a data acquisition unit and forwarded to a data processing unit. In the data processing unit, an OCT whole-eye scan is combined with at least one or several further overlapping tomographic part-eye or whole-eye scans. Reference information is used to register the first whole-eye scan with the further part-eye or whole-eye scans, and the combined whole-eye scan is evaluated and/or displayed on a user surface.

  • Patent number: 9179839
    Abstract: A method for Determining at Least One Parameter for Diagnosis or Risk Assessment of a Disease, including AMD. The distribution of the macular pigment MP of an eye and at least one area A whose bordering line corresponds to a constant optical density MPD and/or concentration MPC of MP is determined by an analysis unit. The bordering line is subjected to a quantitative shape description. At least one parameter DP, suitable for diagnosing a disease and/or the risk of a disease is derived from the quantitative shape description of the bordering line of the areas A. The method is provided for diagnosis or risk assessment but may also be used in the context of treatment of macular pigment deficiency phenomena to select the required supplements. This method, based on the determination of the fractal dimension, is also suitable for diagnosing other diseases such as edemas, actinomycoses, atrophies or lesions.
