Laser Treatment for Nail Fungus — What You Should Know

Discoloured, thickened, brittle or distorted toenails can sometimes be caused by a fungal nail infection, also known as onychomycosis.

These changes can affect your confidence and comfort, particularly when wearing open shoes. However, not every discoloured or thickened nail is caused by fungus, so an appropriate assessment is important.

What is nail fungus?

Fungal nail infections occur when fungi affect the nail or the tissue beneath it. Common signs may include:

• Yellow, white or brown nail discolouration.
• Thickened or brittle nails.
• Crumbling nail edges.
• Changes in nail shape.
• Separation of the nail from the nail bed.

A healthcare professional may recommend further testing when needed to help confirm the cause.

What is laser treatment for nail fungus?

Laser treatment uses concentrated light energy directed at an affected nail. It is offered by some practices as a treatment option for fungal nail infections.

The aim is to target the affected area without surgically removing the nail. The treatment process, number of sessions and suitability depend on the device used and the individual’s circumstances.

It is important to understand that laser treatment is not a guaranteed cure. Evidence for its effectiveness is limited, and results can vary. Some patients may require other treatments, such as prescribed antifungal medication, depending on the diagnosis and their medical history.

What should you expect?

Your podiatrist can assess the affected nail, discuss possible causes and explain suitable treatment options. If laser treatment is being considered, ask about the device, expected benefits, limitations, costs and potential need for additional treatment.

Toenails grow slowly, so even when treatment is successful, visible improvement may take several months as healthy nail grows out.

Can nail fungus be prevented?

You can reduce the risk of fungal infections by:

• Keeping your feet clean and dry.
• Changing socks regularly.
• Allowing footwear to dry between uses.
• Wearing suitable footwear in communal showers.
• Avoiding the sharing of nail clippers and other personal foot-care tools.

If you notice changes in your toenails, professional advice can help you understand the cause and choose an appropriate approach.

Healthy nails begin with the right assessment and informed treatment choices.
