Ophthalmic lens with retinal vascularization monitoring system
First Claim
1. An energized ophthalmic device comprising:
- a retinal vascularization monitoring system comprising an energy source in electrical connection and capable of energizing a transducer, an electronic feedback circuit, a controller comprising a computer processor and a digital media storage device, wherein the retinal vascularization monitoring system is configured for placement within a lens of the ophthalmic device, and wherein the microprocessor implements software code on the media storage device to cause the energized ophthalmic device to;
emit a signal toward at least one portion of a pulsating vessel forming part of a retinal vascularization of an eye;
receive, via the feedback circuit, a return signal from the outputted signal;
image the at least one pulsating location based upon a difference in the emitted signal and the return signal; and
monitor the retinal vascularization by comparing an image of the at least one identified portion of the pulsating vessel with a previous image of the same at least one portion of the pulsating vessel.

Abstract
The present invention discloses an ophthalmic device with a retinal vascularization monitoring system and associated methods. In some embodiments, the ophthalmic device can be a contact lens with a retinal vascularization monitoring system that can be used to monitor temporal changes of a pulsating vessel forming part of the retinal vascularization. Further, the retinal vascularization monitoring system may include elements for delivering a signal, including an audible and/or visual message, to the user that can be useful for identifying abnormal conditions such as a cardiac failure without delay. The audible and/or visual messages can be signals communicated to the user using one or both of the ophthalmic device and a wireless device in communication with the ophthalmic device.
