The purpose of this study is to determine whether the choice of post-operative eye drop administered after selective laser trabeculoplasty (SLT) for glaucoma affects the efficacy in lowering intraocular pressure (IOP).

Drug: Artificial Tears
Phase 4

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double Blind (Subject, Caregiver, Investigator)

Primary Outcome Measures:
  • Intraocular pressure (IOP) lowering [ Time Frame: 6-12 weeks ]
    IOP will be measured before and at 6 and 12 weeks after intervention.

Secondary Outcome Measures:
  • Intraocular inflammation [ Time Frame: 1-12 weeks ]
    The number of patients with persistent inflammation will be measured in each study arm.

Enrollment: 95
Study Start Date: September 2009
Study Completion Date: September 2015
Primary Completion Date: September 2015 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Artificial Tears Drug: Artificial Tears
Artificial saline tears to lasered eye 4 times/day for 4.5 days
Experimental: Non-steroidal anti-inflammatory Drug: Diclofenac 0.1%
Diclofenac sodium 0.1% to lasered eye 4 times/day for 4.5 days
Experimental: Steroid Drug: Prednisolone 1%
Prednisolone 1% to lasered eye 4 times/day for 4.5 days

Detailed Description:
SLT is used to lower intraocular pressure in glaucoma, but it is not know whether the choice of eyedrops administered in the post-operative period affects SLT efficacy. Practitioners commonly use steroid drops, non-steroidal anti-inflammatory drops, or no drops at all. This is a randomized, single-center, prospective, masked clinical trial to determine whether the choice of eyedrop affects efficacy of SLT in glaucoma patients.
