Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Glaucoma, the leading cause of irreversible blindness, affects more than 60 million people worldwide and 1.3 million in France. Its treatment aims to reduce intraocular pressure, in particular by surgery when eye drops and laser treatment are insufficient.

Conventional filtering techniques and MIGS (Minimally Invasive Glaucoma Surgery), including PreserFlo® MicroShunt, pursue the same objective in terms of blood pressure, but differ in terms of their post-operative profile and tolerability.

Existing studies show similar quality of life scores between filtering and MIGS surgeries. However, no direct comparison has yet been made between trabeculectomy, non-penetrating deep sclerectomy and PreserFlo® at 3 and 6 months, making it pertinent to assess their respective effects on patients' quality of life.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Preserflo

Designed to treat primary open-angle glaucoma, PRESERFLO™ MicroShunt is a tiny, soft, flexible stent that helps your eye drain excess fluid, and may help lower eye pressure and prevent further vision loss.

Group Type OTHER

Preserflo

Intervention Type PROCEDURE

Designed to treat primary open-angle glaucoma, PRESERFLO™ MicroShunt is a tiny, soft, flexible stent that helps your eye drain excess fluid, and may help lower eye pressure and prevent further vision loss.

Trabeculectomy

Trabeculectomy is an operation which helps to drain fluid out of the eye and into a small blister (called a bleb) under the surface of the eye (the conjunctiva). The operation creates a kind of trap door for the fluid to pass through, bypassing the normal drainage channel. Drainage of aqueous is improved and this reduces intraocular pressure (IOP).

Group Type OTHER

Trabeculectomy

Intervention Type PROCEDURE

Trabeculectomy is an operation which helps to drain fluid out of the eye and into a small blister (called a bleb) under the surface of the eye (the conjunctiva). The operation creates a kind of trap door for the fluid to pass through, bypassing the normal drainage channel. Drainage of aqueous is improved and this reduces intraocular pressure (IOP).

Non-penetrating deep sclerectomy

Non-penetrating deep sclerectomy (NPDS) is a filtering surgery where the internal wall of Schlemm's canal is excised, allowing sub-conjunctival filtration without actually entering the anterior chamber. This technique was developed to minimize the complications of trabeculectomy

Group Type OTHER

Non-penetrating deep sclerectomy

Intervention Type PROCEDURE

Non-penetrating deep sclerectomy (NPDS) is a filtering surgery where the internal wall of Schlemm's canal is excised, allowing sub-conjunctival filtration without actually entering the anterior chamber. This technique was developed to minimize the complications of trabeculectomy.
