Laser Treatment for Nail Fungus Onychomycosis, or fungal infection of nails—most often on the toes—affects about 12% of Americans, according to the American Academy of Dermatology. Some people are genetically prone to it. In its mild forms, nail fungus is merely a cosmetic problem, but over time it can cause toenails to grow abnormally and become painful when walking. Toenail laser treatment offers a new alternative to oral medication, which carries a risk of liver damage, and a nail lacquer, which has poor efficacy.
Treatments typically take 30 to 45 minutes for up to 10 toes. Depending on the severity of the problem and the laser used, patients may need one to four treatments. It isn’t generally covered by insurance. Whether you choose oral medications or lasers, it can easily take a year for nails to clear entirely.
