Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
1 drop of refrigerated (at approximately 4 degrees Celsius) 0.5% ketorolac tromethamine will be administered in one eye of the subject.
Intervention code [1] 284446 0
Treatment: Drugs
Comparator / control treatment
The wash-out period between treatments is one week. Thus, one week later, 1 drop of room temperature (approximately 22 degrees Celcius) 0.5% ketorolac tromethamine will be administered in the same eye of the subject.

Summary
Brief summary
The use of topical ocular non-steroidal anti-inflammatory drugs (NSAIDs) has been limited by the common side effects of burning and stinging. It has been reported that lowering the temperature of lubricant eye drops results in improved ocular comfort. This research project is to determine if refrigeration of 0.5% ketorolac tromethamine prior to administration improves patient tolerability of the commercially available preparation. These findings may lead to an improved method of delivery that will reduce the adverse effect profile of topical NSAIDs, increase patient compliance and influence future prescribing trends.
