Background A novel medical device that has been approved by the Food and Drug Administration is available for treatment of postsurgical edema. The device emits a low-level, pulsed electromagnetic energy field, which modulates resting cell membrane potential, allowing a return to physiologic resting membrane potential.

Objective To investigate the benefits of electromagnetic energy in eyelid wound healing.

Methods Fifty-seven individuals participated in this randomized, double-blinded study. All patients underwent upper blepharoplasty. At the postoperative visit, patients rated pain, edema, and ecchymosis, and the physician rated edema, ecchymosis, and erythema.

Results There was no difference (p = .76) in patient pain rating when comparing placebo (1.6) with the patch (1.3). Patients reported 6% less edema (p = .11) and 10% less ecchymosis (p = .17) with the active patch eye than in control eye. The physician-graded edema, ecchymosis, and erythema had a mean Likert-type scale difference between placebo and active eyes of −0.3 (p = .12), −0.3 (p = .17), and −0.2 (p = .004) respectively.

Conclusion The use of pulsed electromagnetic energy did not have an effect on postoperative pain, edema, or ecchymosis as rated by patients and physicians. There was a statistically significant reduction in physician-graded erythema for active patch eyes versus placebo.
