*3.3.2 Indications and contraindications*

Thanks to its approach, it can be easily combined with cataract surgery and the combination of both surgeries increases hypotensive efficacy [7, 8]. Therefore, it is indicated in different types of OAG (primary, secondary to pseudoexfoliation and pigment dispersion, corticosteroid and uveitic), with mild or moderate glaucoma damage in a stage prior to conventional surgery, combined with cataract surgery in patients with cataract in the surgical stage in whom a decrease in IOP and/or a reduction in topical hypotensive medication is desired [5].

It should not be used in patients with advanced glaucoma or with a target IOP lower than episcleral venous pressure [5].
