Lasers may work in removing fungus, but the treatment technique requires additional study to establish its effectiveness, according to Mayo Clinic. A study of 24 patients treated with a combination of antifungal nail cream and carbon-dioxide laser therapy revealed the treatment benefited most of the participants.
In 24 studies of laser treatment for nail fungus conducted over a 10-year period, three studies reported positive results of effectiveness, explains MedicineNet. One study of nine patients treated with lasers between one and three times over four to eight weeks produced safe and useful results. A second study of eight patients who received treatment with a similar laser revealed the therapy was beneficial. In the third study, 26 toes were treated with an infrared laser and obtained promising outcomes.
