Abstract
Purpose.
To determine ocular pain duration after routine in-office intravitreal injection and to determine whether topical eyedrops are beneficial in increasing patient comfort.
Methods.
Forty injection-naïve patients receiving routine intravitreal injections of bevacizumab for age-related macular degeneration were randomized into 3 groups: group 1 (control, no drops), group 2 (generic artificial tears), and group 3 (ketorolac tromethamine 0.4% eyedrops). Those who received topical medications were given a Visual Analog Pain score survey and asked to record their pain on a scale from 0 (no distress) to 10 (unbearable distress) daily until a score of 0 was achieved, at which point they were instructed to discontinue use of their given drops. Self-reported pain scores were assessed.
Results.
Pain after routine intravitreal injection lasts on average between 3 and 7 days. Patients receiving topical ketorolac eyedrops reported the fewest average number of pain days (2.25±1.22) vs patients receiving artificial tears (3.54±1.13) or those who received no postprocedure eyedrops (5.13±1.25); p<0.05. At most, patients receiving ketorolac eyedrops reported 3 days of recordable pain. Those who received artificial tears reported at most 5 days of recordable pain, and patients who did not receive any postprocedure eyedrops reported at most 7 days of recordable pain.
Conclusions.
Pain after intravitreal injection is generally mild, may be reduced by postinjection topical ketorolac eyedrops, and lasts less than 1 week.
