A combined analysis of two studies assessing the ocular comfort of antiallergy ophthalmic agents.

Background: Many topical agents with similar efficacies are available for the treatment of ocular allergies. In addition to efficacy, comfort is an important criterion because it affects overall patient satisfaction, compliance, and in turn efficacy.

Objective: The goal of this study was to compare the comfort profiles of permirolast, ketorolac, cromolyn, and nedocromil ophthalmic solutions using combined results from 2 separate clinical trials.
