The gold standard for glaucoma surgery is trabeculectomy, described and applied since the mid-1960s,but new surgical methods less invasive have been developed in order to reduce adverse events. One of the two micro-filtering glaucoma surgery devices available in the market is the Preserflo Microshunt (Santen Pharmaceutical Company Ltd, Osaka, Japan). This is an aqueous drainage shunt to be implanted ab externo to create a full-thickness fistula from the anterior chamber across to the subconjunctival space...
