  • Patent number: 10702140
    Abstract: A visual function evaluation is performed using a sequence of interactions with a mobile device. A patient user may perform a variety of visual tests using the mobile device. The mobile device transmits the test results to a remote server implementing analysis of the visual function results using network service. The network service receives the test results, processes the results, and provides the processed results to a healthcare provider. The processed results may include trends of the user's visual function test performance. The healthcare provider, such as a physician, may optimize and administer treatment based on the data. Early detection of changes in visual function can enable the healthcare provider to individualize treatment, helping to prevent vision loss while minimizing visits to the office, discomfort, and expense.

  • Patent number: 10694936
    Abstract: Embodiments of this invention relate to the generation of wavefronts for measurements, diagnostics, and treatment planning for ophthalmic applications. In some embodiments, a wavefront generator generates light having a uniform wavefront, which is focusable on the retina of an emmetropic eye by the normal function of the emmetropic eye. In some embodiments, the wavefront generator can generate light having a custom wavefront which is not focusable on the retina of the emmetropic eye. In some embodiments, the wavefront generator can receive information relating to an optical aberration of the eye, generate a custom wavefront, and project light having this custom wavefront, which in combination with the optical aberration of the eye is focusable on the retina.
