Abstract
(EN)
A periocular assembly that is configured to be positioned in the fornix of an eye of the user includes a ring; a plurality of electrodes spaced along the ring; a microcontroller operably coupled to the plurality of electrodes; and a sensor assembly coupled to the ring and operably coupled to the microcontroller. A method of stimulating a lacrimal gland of the user includes monitoring eye condition(s) using the sensor assembly; determining, based on the monitored eye condition(s) and using the microcontroller, if the monitored eye conditions(s) exceed a predetermined threshold; and activating, using the microcontroller and in response to the monitored eye condition(s) exceeding the predetermined threshold, the plurality of electrodes to stimulate the lacrimal gland of the user.

Cette invention concerne un ensemble péri-oculaire qui est configuré pour être positionné dans le fornix d'un œil de l'utilisateur, comprenant : un anneau; une pluralité d'électrodes espacées le long de l'anneau ; un microcontrôleur fonctionnellement couplé à la pluralité d'électrodes ; et un ensemble capteur couplé à l'anneau et fonctionnellement couplé au microcontrôleur. Un procédé de stimulation d'une glande lacrymale de l'utilisateur comprend les étapes consistant à : surveiller une/des condition(s) de l'œil à l'aide de l'ensemble capteur ; déterminer, sur la base de la/des condition(s) de l’œil surveillée(s) et à l'aide du microcontrôleur, si la/les conditions de l'œil surveillées(s) dépasse/dépassent un seuil prédéfini ; et activer, à l'aide du microcontrôleur et en réponse au fait que la/les condition(s) de l'œil surveillée(s) dépassent le seuil prédéfini, la pluralité d'électrodes pour stimuler la glande lacrymale de l'utilisateur.
