Summary description of the study

This study aims to determine whether the eyeWatch implant can be a safer and more effective alternative to trabeculectomy in the first-line treatment of glaucoma. The eyeWatch system has the advantage of adjusting the fluid resistance of the eye and thus regulating the intraocular pressure of the patient.

(BASEC)

Intervention under investigation

The eyeWatch implant that allows for non-invasive regulation of the patient's intraocular pressure compared to traditional filtering surgery for the treatment of glaucoma, trabeculectomy.

Disease under investigation

Surgical treatment of glaucoma

(BASEC)

Criteria for participation in trial
Participation is open to all individuals suffering from open-angle glaucoma whose intraocular pressure is no longer controlled by hypotensive medications and who have not yet undergone filtering surgery. (BASEC)

Exclusion criteria
It is closed to individuals who have previously undergone glaucoma surgery (trabeculectomy, SPIC, tube, etc.). Also excluded from the study are individuals who are pregnant or who are already participating in another clinical trial. (BASEC)

Inclusion/Exclusion criteria
Inclusion Criteria: - Aged between 18 and 95 years, - Diagnosis of primary open-angle glaucoma, pseudo-exfoliative glaucoma or pigmentary glaucoma in the study eye (based on [1] glaucomatous optic neuropathy and [2] visual field defects in keeping with optic disc appearance), - Phakic or pseudophakic study eye, - Indication for primary filtering surgery (defined as a corrected IOP = 20 mmHg in the study eye, under maximally tolerated therapy on 2 consecutive measurements made on different days prior to surgery), - Undergoing surgery and post-operative follow-up at one of the investigations centres: Montchoisi Clinic, Swiss Visio, Lausanne, Switzerland OR Manchester Royal Eye Hospital, Manchester, United-Kingdom, - Patient agreed to sign the written inform consent prior to entering the study, - Patient is able and willing to complete post-operative follow-up requirements. Exclusion Criteria: - Diagnosis of secondary glaucoma except for pseudo-exfoliative or pigmentary glaucoma (neovascular glaucoma, congenital glaucoma, uveitic glaucoma…), - Previous filtering or tube surgery in the same eye (including trabeculectomy, deep-sclerectomy and all GDDs / excluding XEN gel stents, angle surgery, cataract surgery and all MIGS), - Recent ophthalmic surgery (less than 3 months prior to inclusion) or indication for a combined procedure (no combined surgeries will be performed), - Narrow iridocorneal angles defined as a Shaffer grade = 2 or presence of iris bombé, - Endothelial cell density < 1500 cells/mm², - Presence of other significant pathologies in the study eye (including extensive conjunctival thinning or scarring, optic neuropathy of non-glaucomatous etiology, retinal vein occlusion, retinal artery occlusion, corneal opacification or irregularities, ocular malformations such as microphthalmia, concurrent inflammation/infection), - Proliferative or severe non-proliferative retinopathy in either eye, - Any sign of past or present uveitis, - Severe systemic disease or disabling conditions (including chronic renal failure, history of organ transplantation), - Current or recent participation in another clinical trial (less than 3 months prior to inclusion), - Pregnancy or breast-feeding, - Inability to give informed consent to participate to a clinical investigation.
