Trial Comparing Ketorolac Tromethamine 0.4% & Prednisolone Acetate 1% in Reducing Post-SLT Anterior Chamber Flare & Cells

A Randomized Prospective Double - Masked Controlled Trial Comparing Ketorolac Tromethamine 0.4% and Prednisolone Acetate 1% in Reducing Post-Selective Laser Trabeculoplasty Anterior Chamber Flare and Cells

Selective laser trabeculoplasty (SLT) is a new alternative to anti-glaucoma medications for the treatment of primary open angle glaucoma. After SLT, many patients experience mild to moderate inflammation inside the eye - specifically in the front chamber of the eye (the part in front of the colored part of the eye). This mild front chamber reaction is typically treated with anti-inflammatory agents such as corticosteroids and nonsteroidal anti-inflammatory agents (NSAIDs). Some physicians do not use these agents as they feel they may interfere with the way the laser works to treat glaucoma. Topical (applied to the surface) corticosteroids can cause an increase in the pressure of the eye (intraocular pressure or IOP), cataract formation, or a possible increase in infection with long-term use. These side effects have not been reported to occur with NSAIDs, which are effective in controlling pain after SLT and reducing signs of inflammation such as irritation, swelling, tenderness, and soreness.

This research study will compare an NSAID, ketorolac tromethamine 0.4% (Acular LS), with a corticosteroid, prednisolone acetate 1% (Pred Forte), and with a placebo, which contains no active medicine (Refresh Tears). Ketorolac tromethamine 0.4%, prednisolone acetate 1%, and Refresh Tears are all FDA (Food and Drug Administration) approved for use in inflammation after surgery.

Detailed Description

Selective laser trabeculoplasty (SLT) is a new alternative to anti-glaucoma medications for the treatment of primary open angle glaucoma. After SLT, many patients experience mild to moderate inflammation inside the eye - specifically in the front chamber of the eye (the part in front of the colored part of the eye). This mild front chamber reaction is typically treated with anti-inflammatory agents such as corticosteroids and nonsteroidal anti-inflammatory agents (NSAIDs). Some physicians do not use these agents as they feel they may interfere with the way the laser works to treat glaucoma. Topical (applied to the surface) corticosteroids can cause an increase in the pressure of the eye (intraocular pressure or IOP), cataract formation, or a possible increase in infection with long-term use. These side effects have not been reported to occur with NSAIDs, which are effective in controlling pain after SLT and reducing signs of inflammation such as irritation, swelling, tenderness, and soreness.

This research study will compare an NSAID, ketorolac tromethamine 0.4% (Acular LS), with a corticosteroid, prednisolone acetate 1% (Pred Forte), and with a placebo, which contains no active medicine (Refresh Tears). Ketorolac tromethamine 0.4%, prednisolone acetate 1%, and Refresh Tears are all FDA (Food and Drug Administration) approved for use in inflammation after surgery.

To date, there is no study that proves that any one of the three study medications is better than the others for care after SLT. We plan to compare the effect of these anti-inflammatory drops in participants after selective laser trabeculoplasty to see if one works better at helping lower the pressure inside the eye after SLT or whether participants would do just as well with non-medicated eye drops. We will also see how well these drops reduce any potential discomfort and swelling that arise.
