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.

An ophthalmic laser surgical system has a built-in imaging sensor for measuring laser focal spot size. An objective lens focuses the laser beam to a focal spot near a reflective surface, scans the focal spot in the depth direction, and focuses light reflected by the reflective surface to form a back-reflected light. A two-dimensional imaging sensor receives a sample of the back-reflected light to generate images of the back-reflected light. During the depth scan, the image contains a well-focused light spot when the laser focal spot is located at a fixed offset distance before the reflective surface, but the light spot in the images is otherwise defocused. The images generated during the scan are analyzed to find the smallest light spot size among the images. The laser focal spot size is then calculated from the smallest light spot size using a magnification factor which is a system constant.

An instrument for imaging the eye and performing ophthalmic diagnostic tests is disclosed that obtain images of the structures of the eye using imaging technology such as optical coherence tomography (OCT). To assist with such imaging and/or provide additional diagnostics, the ophthalmic diagnostic instrument may additionally include a display for presenting images to the subject whose eyes and vision are being evaluated.
