Abstract

La présente invention concerne un anneau d'aspiration cornéenne auto-aspirant, comprenant un anneau cornéen (1) et un anneau auto-aspirant (2) situé à la base de l'anneau cornéen (1). L'anneau auto-aspirant (2) comprend un corps d'anneau auto-aspirant en demi-arc, qui s'adapte exactement au bord de la jonction cornéo-sclérale, et génère automatiquement une aspiration de vide par un effet de rebond après poussée de l'anneau auto-aspirant (2) vers le bas. Par ailleurs, l'anneau auto-aspirant (2) est constitué de caoutchouc souple. Lorsque la surface d'aspiration du caoutchouc souple forme une aspiration de vide, cela peut réduire la gêne du patient. L'anneau d'aspiration cornéenne auto-aspirant est de structure légère, peut être fixé par aspiration au bord de la jonction cornéo-sclérale efficacement, assurer la pénétration de médicament dans l'anneau cornéen (1), et éviter les pertes causées par l'écoulement de médicament liquide hors de l'œil.
