Summary
The purpose of this study is to evaluate the safety and efficacy of the CyPass Implant for lowering intraocular pressure (IOP) in patients with glaucoma who undergo cataract surgery.
Eligibility Criteria
Preoperative Inclusion Criteria:
- Diagnosis of primary open angle glaucoma (POAG)
- Mean diurnal unmedicated IOP of 21 - 33 mmHg
- Normal anterior chamber angle anatomy at site of implantation
- Operable age-related cataract
Exclusion Criteria
- Use of more than 3 ocular hypotensive medications (combination medications count as 2 medications)
- Significant risk associated with washout of ocular hypotensive medication
- Previous glaucoma surgery (with exception of laser treatments to the trabecular meshwork)
- Previous corneal surgery
- Clinically significant ocular pathology, other than cataract and glaucoma
- Diagnosis of acute angle closure, traumatic, congenital, malignant, uveitic, pseudoexfoliative, pigmentary or neovascular glaucoma
