Use of oral hypotensive glaucoma medications for treatment of the fellow eye.
Prior argon laser, selective laser, or micropulse trabeculoplasty within 90 days of enrollment.

Active iris neovascularization, active proliferative retinopathy or other ophthalmic disease that could confound study results.
Presence of an anterior chamber IOL (AC-IOL).
Previous incisional ophthalmic surgery, excluding uncomplicated clear corneal phacoemulsification (cataract) surgery at least 6 months prior to enrollment.
Fellow eye with poorer than 20/200 best-corrected visual acuity (BCVA)

Use of oral hypotensive glaucoma medications for treatment of the fellow eye.
inability to discontinue use of blood thinners within the surgeon's standard preoperative or postoperative instructions.
Disorders that pose a fall risk, as well as compromise ability to take a visual field exam and take glaucoma medications (e.g., Parkinson's disease),
inability to reliably complete visual field testing over the course of the study,
Angle closure glaucoma or narrow anatomical chamber angle as identified by gonioscopy and classified as Shaffer Grade 0 or 1.
