An apparatus, and corresponding method, for determining a property of an eye includes a housing with a proximal port that receives an eye and also light from the eye. The housing further includes a distal port, and the two ports together form a visual channel providing an open view to enable the eye to see target indicia external to and spaced away from the housing. A wavefront sensor within the housing is configured to receive the light from the eye via the optical path and to measure a wavefront of the light. A determination module determines an objective refractive correction based on the wavefront and predicts a subjective refractive preference of a person having the eye based on the objective refractive correction. Embodiments can be handheld, and binocular, and predict subjective refraction based on demographic and other information.

Provided is a system for automatic examination of a body part of a subject, including a support configured to support a subject's body portion including said body part; a measuring subsystem including at least one sensor configured to detect at least one feature of the subject, a mechanical subsystem configured for receiving at least two examination devices and for positioning the at least two examination devices and/or said support in operative positions; and a control unit.

The present invention relates to systems for low-energy (e.g., 1.0 nJ-7.0 nJ) photoacoustic microscopy and methods for employing such systems. In certain embodiments, such systems employ a low-energy nanosecond pulsed laser beam (NPLB), at least two amplifiers, and a data acquisition system with at least three channels to generate at least three digital signals (e.g., which are averaged and normalized to the energy of the NPLB). In other embodiments, provided herein are systems for combined use of photoacoustic microscopy, dye-based microscopy (e.g., with fluorescein), and optical coherence tomography.

Embodiments of the invention are directed towards systems, methods and computer program products for providing improved eye tests. Such tests improve upon current eye tests, such as visual acuity tests, by incorporating virtual reality, software mediated guidance to the patient or practitioner such that more accurate results of the eye tests are obtained. Furthermore, through the use of one or more trained machine learning or predictive analytic systems, multiple signals obtained from sensors of a testing apparatus are evaluated to ensure that the eye test results are less error-prone and provide a more consistent evaluation of a user's vision status. As it will be appreciated, such error reduction and user guidance systems represent technological improvements in eye tests and utilize non-routine and non-conventional approaches to the improvement and reliability of eye tests.

An eye measurement system includes an optical system. The eye measurement system is disposed in a housing which includes an aperture for providing light to and from the optical system and a subject's eye while the subject is separated and spaced apart from the housing, and the eye is not maintained in a fixed positional relationship with respect to the housing. An optical system movement arrangement moves the optical system. An automatic eye tracking arrangement ascertains a current positional relationship of the eye with respect to the optical system without human assistance, and in response thereto controls the optical system movement arrangement to move the optical system into a predetermined positional relationship with respect to the eye, for measurement of the eye, without human assistance. The eye measurement system can make objective, and/or subjective, refraction measurements of the eye.

The present disclosure relates generally to systems and methods for testing and determining a corrective lens prescription for a patient. In an example embodiment, a method includes receiving, in a remote device, a link to enable a patient to launch an interface on the remote device for interacting with a patient terminal in a hand held manner. The interacting includes receiving instructions from a server and enabling the patient to make at least one input to the server via the remote device over a communication interface to control the first computerized screen from a distance. The method also includes displaying a figure on the first computerized screen and enabling the patient to make a least one input via the remote device to change a size of the figure. The input corresponds to a sphere measurement of the patient.
