Laser for Toe Fungus: What to Know

Toe fungus usually refers to a fungal infection of the toenail. Thickening, yellow or white colour, crumbling and separation from the nail bed can also result from injury, eczema or another nail disorder. A clinician may clip or scrape the nail for testing before choosing treatment. Athlete's Foot can coexist and may help reinfect the nail.

Laser devices use focused energy at the nail and surrounding area. The aim is to support improvement in the affected nail, but a damaged nail grows slowly, so visible change takes time. A treatment course may involve repeated visits. Temporary warmth, tenderness, redness or swelling can occur, and the device may not be appropriate for every nail or infection.

Ask whether testing is needed and whether laser is being offered alone or alongside an antifungal. Depending on the result, the clinician may discuss Topical Antifungal Treatment, Oral Antifungal Treatment or, for selected severe nails, Nail Surgery. Keep feet dry, change socks regularly, let footwear dry, trim nails carefully and avoid sharing nail tools. Treating athlete's foot and disinfecting or replacing contaminated tools can reduce reinfection.

Arrange medical assessment promptly for a painful, swollen or draining toe, spreading redness, fever, or a dark streak that is new or changing. People with diabetes, reduced circulation, nerve problems or a weakened immune system should seek professional advice early for foot or nail changes. Contact the clinic if treatment causes blistering, severe pain or worsening inflammation.
