Abstract: A processor signals a display to show a target. Optics is positioned in an optical path taken by the target, as shown by the display, from the display to the eye of a user. The optics is configured to change accommodation by the eye and has adjustable focal length that enables the user to see the target with changing acuity. The processor then obtains an indication that the eye of the user is focused on the target. In response, the processor signals an alignment mechanism to align a sensor in the device to the eye of the user. After signaling the alignment mechanism to align the sensor to the eye of the user, the processor obtains sensor data, produced by the sensor, which measures a property of the eye. Other aspects are also described and claimed.

Abstract: A device includes an eye penetration member extending from a proximal end to a distal end and including a body defining a lumen for receiving a liquid column and including at least one port extending to the lumen. The distal end is configured for insertion into the vitreous humor of an eye. A pressure modulation system is in fluid communication with the lumen and includes a low frequency modulation mechanism and a high frequency modulation mechanism that cooperate to draw vitreous humor into the lumen and liquefy the vitreous humor. The high frequency pressure modulation imparts acoustic pressure modulation to the liquid column at the proximal end of the eye penetration member which is transferred to the distal end of the eye penetration member.

Abstract: An apparatus for assisting with alignment of a dropping nozzle of an eye dropper bottle includes a tubular hub configured for selective engagement with the dropping nozzle to laterally surround the dropping nozzle within a hub lumen thereof.
