Primary outcomePrimary: Subjective Injection Pain — 7.0; 3.1; 3.0; 1.8 units on a scale

Summary

The cryoanesthesia (CA) device is designed to provide anesthesia to a focal area on the surface of the eye immediately prior to intraocular injections. The investigators plan to carry out a pilot study to collect preliminary data on the effectiveness of the cryoanesthesia (CA) device in minimizing the pain caused by intravitreal injections (IVT).
