Intravitreal injections (IVT) have become the most common procedure performed by retina specialists. A number of studies have demonstrated that patients can have significant anxiety and discomfort during IVT. Current methods of anesthesia for IVTs include topical anesthetic drops, application of a cotton tip applicator soaked with lidocaine, preservative free lidocaine gel, as well as subconjunctival lidocaine injection.
Factors which influence the choice of anesthesia by retina specialists include patient satisfaction, procedure workflow and efficiency, and cost. An alternative method of anesthesia that is well tolerated by patients and has a rapid onset of action may improve both the patient experience as well as clinical workflow.
