Inclusion criteria
✓. Patient must be 18 years of age or older.
✓. Patient must have primary open angle glaucoma or pseudo-exfoliative glaucoma in the study eye; diagnosis is based on glaucomatous optic neuropathy, Shaffer angle of +2 and visual field defect attributed to glaucoma (at least two consecutive abnormal visual field test results, defined as a pattern SD (PSD) outside the 95% normal confidence limits and/or glaucoma Hemifield Test (Carl Zeiss Meditec, Inc.).
✓. Eye to be treated must be phakic or pseudophakic eye with no ocular disorder or ocular diseases but cataract, and no prior surgical intervention in study eye but cataract surgery with clear corneal incision and trabeculoplasty performed \> 3 months ago.
✓. Patient is indicated for filtration surgery.
✓. Presence of ocular hypertension, defined as an intraocular corrected pressure (IOP) ≥ 21 mm Hg in the study eye, while on maximal tolerated medications . This IOP level of above or equal 21 mmHg must be verified and recorded in the most recent 2 consecutive measurements (but not taken on the same day) prior to operation.
✓. Best corrected visual acuity (BCVA) better than 20/200 in the fellow eye.
✓. Optic neuropathy is attributed exclusively to glaucoma.
✓. Patient or legal guardian agrees to sign written informed consent prior to study participation.
Exclusion criteria
✕. Patient has previously undergone a non-penetrating glaucoma surgery with the IOPtima CO2 Laser System in fellow eye.
. Diagnosis of glaucoma other than primary open angle glaucoma or pseudo-exfoliative glaucoma.
✕. History of previous intraocular surgery in the study eye; referring to but not limited to glaucoma filtering surgery (penetrating and non-penetrating), laser gonioplasty, corneal transplant, and history of any other laser ocular procedures except for laser trabeculoplasty surgery.
✕. Laser trabeculoplasty surgery within the last three months in the study eye.
✕. Study eye is aphakic.
✕. Patients with previous cataract extraction with scleral tunnel and or conjunctival incision in the study eye.
✕. Proliferative or severe non-proliferative retinopathy in either eye.
✕. Eyes with (dilated) pupil diameter of less than 2 mm in the study eye.
