Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Background and Objective: To evaluate the efficacy of cooled versus room temperature artificial tears in reducing post intravitreal injection (IVI) ocular discomfort.

Patients and Methods: Patients receiving IVI were randomized to either cooled or room temperature tears intervention groups. Both groups rated their ocular discomfort following IVI before intervention and again after administration of cooled or room temperature tears.
