Non-invasive periocular device for dry-eye treatment and closed-loop methods for operating same

A device configured to be worn on an eye of a user and configured to circumscribe the limbal ring of the eye, the device comprising:

• a lacrimal gland stimulator assembly, wherein the stimulator assembly comprises:
• a plurality of electrodes spaced along the device;
• a first microcontroller;
• and
• a lead assembly extending along at least a portion of the device;
• wherein the lead assembly extends between the first microcontroller and the plurality of electrodes to operably couple the plurality of electrodes to the first microcontroller;
• and
• a sensor assembly operably coupled to the stimulator assembly;
• wherein the first microcontroller is configured to:
• receive eye condition(s) data relating to a monitored eye condition(s) from the sensor assembly;
• store historical monitored eye condition(s);
• store health factors associated with the user received from a second microprocessor spaced from the periocular assembly;
• and
• activate, using the microcontroller and in response to the monitored eye condition(s), the historical monitored eye condition(s), and the health factors, the plurality of electrodes to stimulate a lacrimal gland of the user.

A dry-eye treatment device comprising:

• a ring forming an opening, wherein when the ring is positioned on an eye of a user, a portion of the eye extends through the opening of the ring;
• a first microcontroller coupled to the ring and in wireless communication with a second microcontroller that is spaced from the first microcontroller;
• a sensor assembly coupled to the ring and operably coupled to the first microcontroller;
• wherein the sensor assembly is configured to monitor eye condition(s) of the eye;
• and
• a lacrimal gland stimulator assembly coupled to the ring and operably coupled to the first microcontroller;
• wherein the first microcontroller is configured to:
• store a target eye condition(s) associated with the eye of the user;
• receive external data associated with the user from the second microcontroller, wherein the external data comprises environmental factors associated with the user, health factors associated with the user, and activities of the user;
• receive data from the sensor assembly regarding the eye condition(s) of the eye;
• compare the received data regarding the eye condition(s) with the target eye condition(s) to determine a difference;
• stimulate the lacrimal gland of the user using the lacrimal gland stimulator assembly based on the difference and the external data.
