LDL-MMC-chitosan nanoparticles release from hyaluronic acid film. The hyaluronic acid film is implanted into subconjunctival space at the filtering site, with conjunctival wound is sutured, and LDL-MMC-chitosan nanoparticles release constantly from the hyaluronic acid film. LDL-MMC-chitosan nanoparticles is made by chitosan nanocontainer encapsulating MMC, and then combined with LDL.
