Brief Summary

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

The study aims to investigate postoperative outcomes after two different MIGS implants (MINIject or Hydrus) in combination with cataract surgery for patients with glaucoma.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The study aims to investigate postoperative outcomes in terms of intraocular pressure as well as safety measures after two different MIGS implants (MINIject® or Hydrus®) in conjunction with cataract surgery (CS) for patients with chronic glaucoma. The patients will be followed up for 5 years after the date of their implantation. Standard ophthalmologic assessments including measurement of intraocular pressure, fundus examination and ocular imaging with OCT (Optical Coherence Tomography). Assessment of life quality as well as adverse events will be performed.

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

Device: Phacoemulsification combined with minimally invasive glaucoma surgery (MIGS), either Hydrus Microstent or MINIject. The patients will be randomized (1:1) to each treatment/intervention arm.

Study Groups

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

MINIject

MINIject with Cataract Surgery

Group Type ACTIVE_COMPARATOR

MINIject with Cataract Surgery

Intervention Type DEVICE

Patients will be randomized to receive either a MINIject implant or a Hydrus Microstunt in conjunction with cataract surgery. If randomized to MINIject, the device will be implanted into the supraciliary space with a minimally invasive ab interno approach. It is designed to be implanted with its head in the anterior chamber and its body in the supraciliary space, leading to improved natural uveoscleral outflow by directing aqueous humor from the anterior chamber to the sub-scleral space. Cataract surgery will be performed with phacoemulsification.

Hydrus Microstent

Hydrus Microstent with Cataract Surgery

Group Type ACTIVE_COMPARATOR

Hydrus Microstent with Cataract Surgery

Intervention Type DEVICE

Patients will be randomized to receive either a Hydrus Microstunt or a MINIject implant in conjunction with cataract surgery. If randomized to Hydrus Microstent, the device will be implanted into Schlemm's canal through the trabecular meshwork in order to dilate and restore the natural aqueous outflow pathway through Schlemm's canal, leading to a reduction of intraocular pressure.

Cataract surgery will be performed with phacoemulsification.
