Results of Patients With Glaucoma Undergoing Minimally Invasive Glaucoma Surgery in Conjunction With Cataract Surgery

Inclusion Criteria: Male or female subjects 45 years of age or older A visually significant age-related cataract in both eyes Diagnosis of mild OAG VF characteristics consistent with glaucoma with mean deviation not worse than -6.00 dB and without fixation threatening scotoma AND/OR with nerve abnormalities consistent with glaucoma (rim notching, rim thinning, disc hemorrhage, nerve fiber layer loss) Medicated IOP ≤25 mmHg on 1-3 hypotensive medications Glaucoma must be judged as stable by investigator based on review of subject medical records Stable VF at least 1 year prior to surgery Stable nerve fiber layer at least 1 year prior to surgery IOP stable on current medication regimen at least 3 months prior to surgery Shaffer grade of ≥ III in all angle quadrants Potential of best corrected visual acuity at distance in the investigator's judgement of at least 0.1 logMAR (20/25) postoperatively Able and willing to comply with follow up visits Understands and signs the informed consent Both eyes of the subject should undergo surgery within 21 days of each other to ensure adequate timing for final visit window of 90 days ± 21 days post operatively Exclusion Criteria: Previous incisional glaucoma surgery or cilio-ablative surgery Prior laser trabeculoplasty within 90 days of surgery Pseudoexfoliative, angle closure, uveitic, congenital, traumatic, angle recession, or neovascular glaucoma. Moderate glaucoma with VF mean deviation between -6.00 dB and -12.00 dB Severe and/or progressive glaucoma defined as VF mean deviation worse than -12.00 dB Consistent worsening of visual field on review of subject medical records Consistent and progressive thinning of nerve fiber layer on review of subject medical records Uncontrolled IOP on maximum glaucoma medications Historically poor IOP control with medical therapy Severe focal notching of the optic nerve rim Expectation for future need of incisional glaucoma surgery Ocular pathology or other medical condition which, in the investigator's judgment places the subject at increased risk of complications or significant vision loss during study period Ocular pathology that in the investigator's judgment may impact visual acuity postoperatively, i.e., significant ocular surface disease, corneal scarring, blepharitis, epiretinal membrane, macular degeneration, history of significant ocular trauma with sequela, etc. Pregnant or breastfeeding women Prior refractive surgery e.g., LASIK, RK, PRK, etc. Subjects with significant complications during surgical procedure e.g., broken capsule, Hydrus Microstent complication, will be exited from the trial Subjects who experience visually significant complications related to the Hydrus Microstent during the study period will be exited from the trial
