*3.4.2 Indications and contraindications*

ABiC is effective at reducing IOP and medication use in eyes with uncontrolled primary open-angle glaucoma (POAG) with or without cataract surgery [9]. It is useful in combination with cataract surgery as incisions resemble those of a typical cataract extraction and the IOP lowering effect of both procedures is enhanced [10]. Moreover, the addition of ABiC to phacoemulsification could be considered astigmatically neutral [10].

As in the resto of MIGS, the epiescleral venous-resistant floor limits the IOPlowering effect, so ABiC seems to be indicated such as a minimal invasive technique that does not affect future conjunctival bleb surgeries in patients with or without cataracts and POAG that need a modest IOP-lowering effect in order to reduce IOP or medication [10].
