Brief summary

NorMIGS is a non-randomized clinical study of intraocular pressure lowering effect and complications after Preserflo microshunt implantation versus other types of glaucoma surgery. The study is conducted in the Department of Ophthalmology, Oslo University Hospital, Norway.

Interventions

Implantation of Preserflo microshunt (Santen) to lower intraocular pressure

PROCEDURETrabeculectomy

Trabeculectomy surgery to lower intraocular pressure

PROCEDUREOther MIGS

Other MIGS than Preserflo microshunt (e.g., XEN gel stent, iStent inject) to lower intraocular pressure
