About this study
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
- Procedure: Preserflo microshunt — Implantation of Preserflo microshunt (Santen) to lower intraocular pressure
- Procedure: Trabeculectomy — Trabeculectomy surgery to lower intraocular pressure
- Procedure: Other MIGS — Other MIGS than Preserflo microshunt (e.g., XEN gel stent, iStent inject) to lower intraocular pressure
Primary outcomes
- Intraocular pressure (8 weeks after surgery)

* Ability to cooperate fairly well during the examinations
* Willing to participate in the study and capable of providing informed consent
Exclusion Criteria:
\- High intraocular pressure due to increased episcleral venous pressure, hemorrhagic glaucoma, traumatic glaucoma or uveitis glaucoma
Study locations
