Microcurrent Stimulation is the application of a small electrical current to tissues using electrodes placed on the skin. It has been used for years with FDA approval for the repair of injured soft tissues and for treating muscular-skeletal pain.
Several small studies have applied microcurrent stimulation to macular degeneration. They considered various levels of stimulation, frequencies, pulse rates and ways of applying the stimulation to the area around the eyes. Many have shown promising results with no adverse affects.
A new study in Korea, at the Korea University Ansan Hospital in Seoul, is currently underway. Study subjects will participate in the trial for 16 weeks. If determined to be safe and effective, microcurrent stimulation would be one-step closer to official approval by medical authorities.

That was 2022, what has happened with microcurrent since then? Was the study in Korea completed? What were the results.
Good question. We have not seen any results published for that trial. There have been many small studies that were encouraging, but mostly anecdotal. The best I’ve seen is a 2015 study published in PubMed ( https://pmc.ncbi.nlm.nih.gov/articles/PMC4689270/ ). Asia is selling MC instrumentation and healthcare professionals are using it “off-label”. Let us know if you find anything better. Thank you, MDF
