Magnetic neurostimulation improves corneal staining, quality of life in dry eye patients

SAN DIEGO — Magnetic neurostimulation reduced corneal staining and improved quality of life in patients with dry eye, while proving to be a safe treatment, according to a speaker.
A multicenter, open-label clinical trial enrolled 15 patients with moderate to severe dry eye to receive the 11-minute magnetic neurostimulation treatment in a single eye, David Zadok, MD, said at the American Society of Cataract and Refractive Surgery meeting.
In the first week after treatment, a statistically significant change in quality of life was reported, with a statistically significant reduction in lubricant use reported at 2 weeks after treatment.
“The reduction in punctate epitheliopathy score in treated eyes from baseline to week 8 was statistically significant,” Zadok said.
No adverse-related events were recorded from the device or treatment, although the magnetic stimulation did result in a tingling sensation reported by patients.
A second trial is currently enrolling patients and will treat both eyes in 15 subjects, Zadok added.
“The treatment with noninvasive ocular repeated magnetic neurostimulation in patients with moderate to severe dry eye disease was found to be safe, reduce corneal staining score, improve quality of life and reduce the need to use lubricants,” he said. – by Rebecca L. Forand
