Publication number: 20230255480Abstract: The present application describes the addition of various feedback mechanisms including visual and audio feedback mechanisms to an ophthalmic diagnostic device to assist a subject to self-align to the device. The device may use the visual and non-visual feedback mechanisms independently or in combination with one another. The device may provide a means for a subject to provide feedback to the device to confirm that an alignment condition has been met. Alternatively, the device may have a means for sensing when acceptable alignment has been achieved. The device may capture diagnostic information during the alignment process or may capture after the alignment condition has been met.Type: ApplicationFiled: April 28, 2023Publication date: August 17, 2023Applicants: Carl Zeiss Meditec, Inc., Carl Zeiss Meditec AGInventors: Alexandre R.

Patent number: 11395589Abstract: Ophthalmic imaging systems, particularly slit-scanning ophthalmo-scopes, are capable of characterizing refraction over the entire field of view of the system. Light from the light source of the system illuminates a region of the eye and the returning light is measured on a detector. The deviation of the location of the returning light from a predetermined location on the detector is measured. The deviation corresponds to the mismatch between the refractions of the imaging system and the eye. The light can be scanned across the full field of view to characterize the entire field. A second illumination source traveling along a second illumination path can be used to improve the characterization. The characterization can be of use for optimizing the focus of the instrument and for assessing the condition of the eye, including assessing myopia and astigmatism in the periphery.Type: GrantFiled: March 29, 2018Date of Patent: July 26, 2022Assignees: CARL ZEISS MEDITEC, INC., CARL ZEISS MEDITEC AGInventors: Matthew J.

Patent number: 10571243Abstract: Various systems and methods for sequential angle illumination to achieve ultra-high resolution optical coherence tomography (OCT) images. One example OCT system includes a light source, a beam divider, sample arm optics, a detector, and a processor. The light source generates a light beam to illuminate the sample. The beam divider separates the light beam into reference and sample arms. The sample arm optics sequentially illuminates a location in the sample with the light beam from different angles. The detector receives light returned from the reference arm and the sample illuminated at each angle and generates signals. The processor combines the signals to generate an image, which has a transverse resolution that is higher than the transverse resolution achieved from the signal generated from a single angle.Type: GrantFiled: February 10, 2017Date of Patent: February 25, 2020Assignees: CARL ZEISS MEDITEC, INC., CARL ZEISS MEDITEC AGInventors: Matthew J.
