Reply: Drs. Agrawal and Khurana raise valid points. We would like to clarify that the patients were masked to which group they were assigned and were not aware of whether they were receiving a ketorolac-soaked bandage contact lens or a plain lens. This is important because, as Drs. Agrawal and Khurana rightly point out, the placebo effect could play an important role in pain management.

The second point is also relevant. We agree that a contralateral-eye study might be a better way to assess the control of pain because of the difference in pain perception between individuals. Our work is ongoing, and we look forward to assessing the results in a contralateral-eye study.
