Subconjunctival air dissection technique for mitomycin C application combined with primary needling for XEN Gel Stent implant

摘要

This film exhibits a surgical technique for subconjunctival mitomycin C application using air dissection prior to XEN Gel Stent implant followed by primary needling. A 30-gauge sharp needle is used to enter the subconjunctival space in the superonasal quadrant and 0.3 mL of air is injected to achieve subconjunctival 'air dissection'. 0.2 mL of 0.2 mg/mL mitomycin C is then injected into this dissection plane. The XEN Gel Stent implant is inserted ab interno under direct visualisation and primary needling is performed with a 30-gauge needle to ensure there is no entrapment within Tenon's capsule.
