Randomized Controlled TrialPain associated with local anesthetic injection in eyelid procedures: Comparison of microprocessor-controlled versus traditional syringe techniques.
To evaluate the pain associated with local infiltration of the eyelid, using a microprocessor-controlled delivery system (CompuMed, using the Wand), as compared with traditional manual syringe infiltration technique. ⋯ The Wand was effective at significantly reducing the pain associated with local anesthetic infiltration in minor eyelid surgical procedures. Patients appear to feel pain from the initial needle stick but not during the actual injection.
