Purpose: To determine if prior administration of an anesthetic drop alters the amount of discomfort experienced with the administration of dilating drops. Methods: Subjects were screened for any external ocular disease precluding normal corneal sensation. 20 subjects then, with randomization, received topical tetracaine 0.5% followed by tropicamide 1% and phenylephrine 2.5% in one eye, and tropicamide and phenylephrine without tetracaine in the other eye. On a scale of 1 to 10 (10 being the greatest), subjects then stated the amount of discomfort experienced with the application of each set of drops. Results: The mean discomfort with the use of tetracaine was 3.04, versus 3.38 without tetracaine. The mean difference in discomfort was greater without prior anesthetic drops by only 0.34 (+/–1.97). Conclusions: Prior administration of topical anesthetic eye drops does not significantly alter the discomfort experienced with the application of dilating drops.
