Abstract
Adjustable vision modification using various systems, devices, and processes are provided. Adjustable vision modification may include sensing ocular related physiological activities of a user and making adjustments in an ocular device or ocular system to change the vision of the user. Various sensors and sensor locations may be employed in embodiments to sense or otherwise obtain these physiological activities. Likewise, various ocular devices, ocular processes, and ocular systems may be employed for improving vision.
Claims19
An electro-active intraocular lens comprising:
- an adjustable intraocular lens;
- a plurality of sensor arms extending away from the adjustable intraocular lens, each of the arms comprising a pair of electric sensors, the pair of electric sensors comprising a driving electrode and a sensing electrode;
- and
- a processor configured to receive EMG signals sensed by sensing electrodes of the plurality of sensor arms, and to control focus of the adjustable intraocular lens using the received EMG signals.
An ocular system for improving vision comprising:
- an adjustable intraocular lens;
- a pair of haptic sensor arms extending away from the adjustable intraocular lens, each of the arms comprising a mated pair of electric sensors, the mated pair of electric sensors comprising an anode sensor and a cathode sensor;
- and
- a processor configured to receive EMG signals sensed by the anode sensors and the cathode sensors and to control focus of the adjustable intraocular lens using the received EMG signals.
