  • Patent number: 10420463
    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: 10383513
    Abstract: An objective phoropter utilizing an illuminated keratometric object projecting its illumination onto the subject's cornea, and imaging the reflection therefrom in an imaging camera. Image processing of these images is used to improve the focusing and centering of the cornea subject's eyes. Once the correctly focused position of the eyes is obtained relative to the keratometer object, an accurate longitudinal position of the eyes relative to the lens wheel assemblies can also be achieved. This results in more accurate prescription generation than in prior art systems where the eyes may not be accurately positioned relative to the lens wheels. Additionally, the lens combinations of the entire phoropter wheel can be calibrated using an artificial eye having adjustable levels of aberration. Each lens combination is adjusted to supposedly correct a selected aberration level, and any residual aberration measured represents the correction to be applied to that lens combination.

The method may be used to select an intraocular lens to be implanted into an eye and is equally suitable for spherical, aspherical, toric and multifocal IOLs.

  • Patent number: 10123687
    Abstract: A method for selecting an intraocular lens (IOL), to optimize the results of refractive procedures on the eye. According to the invention, the method for selecting the IOL includes: a) determining the required biometrical parameters of the eye; b) using the parameters for a corresponding eye model; c) evaluating, using ray tracing, the data of an IOL to be implanted; d) selecting, on the basis of said data, an IOL to be implanted; and e) repeating the method steps c) and d) for further suitable IOLs. To optimize the method, different measuring methods are used to determine the biometrical parameters, a corresponding patient-specific eye model is identified, and, when selecting the IOL, additional retinal image metrics are taken into consideration alongside the determined data. The method according to the invention permits the optimized selection of a spherical, aspheric, toric or multifocal IOL for implantation.

  • Patent number: 10089966
    Abstract: A display device is mounted on and/or inside the eye. The eye mounted display contains multiple sub-displays, each of which projects light to different retinal positions within a portion of the retina corresponding to the sub-display. The projected light propagates through the pupil but does not fill the entire pupil. In this way, multiple sub-displays can project their light onto the relevant portion of the retina. Moving from the pupil to the cornea, the projection of the pupil onto the cornea will be referred to as the corneal aperture. The projected light propagates through less than the full corneal aperture. The sub-displays use spatial multiplexing at the corneal surface. Various electronic devices interface to the eye mounted display.

  • Patent number: 10064757
    Abstract: Transcorneal and fiberoptic laser delivery systems and methods for the treatment of eye diseases wherein energy is delivered by wavelengths transparent to the cornea to effect target tissues in the eye for the control of intraocular pressure in diseases such as glaucoma by delivery systems both external to and within ocular tissues. External delivery may be effected under gonioscopic control. Internal delivery may be controlled endoscopically or fiberoptically, both systems utilizing femtosecond laser energy to excise ocular tissue. The femtosecond light energy is delivered to the target tissues to be treated to effect precisely controlled photodisruption to enable portals for the outflow of aqueous fluid in the case of glaucoma in a manner which minimizes target tissue healing responses, inflammation and scarring.
