Enrollment: 164
Study Start Date: January 2010
Study Completion Date: December 2013
Primary Completion Date: December 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Cataract Surgery Only Procedure: Cataract Surgery
Subjects will be randomized to one of two groups. In this case, subjects will undergo cataract surgery only.
Experimental: Treatment with Cataract Surgery & Stents

Other Name: Cataract surgery, stent implantation

Detailed Description:
Glaucoma is a collection of disorders characterized by progressive loss of visual field due to optic nerve damage. It is a leading cause of blindness in the United States, affecting 1-2% of individuals aged 60 and over. Management of glaucoma requires chronic, life-long treatment with a spectrum of therapeutic options including medications, laser treatment and surgical implants. The common goal among the various therapies is to lower intraocular pressure to target levels in order to prevent loss of visual fields from excessive pressure on the optic nerve.
