Brief Summary
The purpose of this study is to compare the safety \& effectiveness of the two types of cataract and glaucoma surgeries. Results from this study may improve the surgical and post surgical management and long term management of patients with these conditions in the future

Outcome Measures
Primary Outcomes (1)
Post-Op outcomes of IOP less than or equal to 16mm Hg without additional ocular hypotensive medications
Assessments made at 3 months post op, 3 month intervals for at least 2 years post surgery
Study Arms (2)
1
NO INTERVENTIONStandard 1 site Procedure using a fornix based incision, performed superiorly
2
EXPERIMENTAL2 Site Combined Procedure
Interventions
2 Site Combined Procedure: in which a temporal clear cornea approach would be used for the cataract/IOL part of the procedure, and immediately thereafter the superior limbus would be employed for a limbus-based trabeculectomy
Eligibility Criteria
You may qualify if:
- Meet the current criteria for combined procedure surgery:
- A visually significant cataract(ie: an opacification of the crystalline lens resulting in a reduction of visual performance affecting daily living
- Open angle or mixed mechanism glaucoma inadequately controlled on current therapy, or requiring two or more medications for control, or with advanced visual field and optic nerve damage.
You may not qualify if:
- Subjects with normal tension glaucoma(defined as those subjects in whom no IOPs greater than 21 mm Hg\[preceding or during therapy\]have been recorded)
- Subjects with uveitis
- Subjects with neovascular glaucoma
- Severe conjunctival inflammation or scarring
- Subjects who have had previous incisional ocular surgery in the same eye
- No subjects will have second eye operated on within 8 weeks of the first eye
