Can I paint my toenails while getting PDT?

Yes!    We have a medical grade nail polish in office that can be used while having PDT treatment and afterwards, while continuing on with topical antifungal medication. This nail product is permeable, and will allow penetration of topical medications beneath the colour.  This polish is  free of harsh chemicals, and contains moisturizers for the nail as well as antifungal agents which aid in the treatment of the fungal nails. We kindly ask that the polish be removed for each PDT treatment, but it can be applied in between. Unfortunately drug store and pedicure nail polish does not allow permeability, and can make fungal infections beneath the nail worse. As such we discourage the use of drug store/ pedicure polish with fungal nail infections. 

But wait? How do I know if I have fungus? 

We have a quick, cost effective in office test to help determine if you do indeed have nail fungus. There are several conditions which can cause changes in the nail that are not fungus, so this test can offer peace of mind as well as to make sure that if we are treating, we should be!

How much will this cost?

There are many different lasers on the market to treat toenail fungus. Some come with very high treatment prices, and others much more reasonable. The light we use is a cold laser which is much more cost effective than its counterparts. This allows us to offer treatment at a reasonable price. This is much more affordable and accessible to our clients. Each treatment is billed individually and can be stopped at any time if the client chooses to do so with no further obligation. The grand total between  4 photodynamic laser sessions including nail care equals approximately $350. These treatments are typically covered under employee health benefits chiropody/ podiatry services.

Photodynamic Laser Therapy

​For Nail Fungus

Photodynamic therapy (PDT),  is a form of phototherapy involving light and a photosensitizing chemical substance, used in conjunction with molecular oxygen to elicit cell death (phototoxicity). PDT has proven ability to kill microbial cells, including bacteria, fungi and viruses.

When the photosensitive agent is irradiated with a certain wavelength of light, it changes the energy structure of the photosensitive chemical, and becomes very destructive to adjacent cells.

Common Causes of Onychomycosis:

Shared nail polishes, unsterile manicures and pedicures
Communal showers, pools, hot tubs, and saunas
Damaged or injured nails
Excessive wearing of closed toe shoes

Frequent contact with a person who has fungal nails

Photodynamic therapy has a wide variety of applications. Here at Custom Foot Clinic, we use the Genesis Health Lights for photodynamic treatment of toenail fungus. There has been much published research on its effectiveness. In our office, we have seen very encouraging results.

Do you need PDT?

If your nails are discoloured, thick, hard to cut, or crumbly, it is likely that you have a fungal nail infection called Onychomycosis. This is a very common nail disease and constitutes over half of all nail abnormalities. This condition may affect toenails or fingernails, but toenail infections are more common.

What to expect during treatment with PDT

The photosensitive agent we use specific to toenail fungus is a pharmaceutical grade blue dye, methylene blue. The typical course of treatment involves a series of 4 -5 sessions. In each session we will apply a generous amount of the methylene blue, and apply the medical light to the affected nails for several minutes.  We will also often debride/ reduce the thickness of the dead nails such that the dye has the best penetration possible.  We complete each treatment 3 weeks apart such that the entire treatment spans just over 12 - 15 weeks. During and after the PDT cycle, we also treat the nail with a topical antifungal medication applied at home daily. After the PDT treatments are complete, we typically see our patients every 4-6 weeks so that we may clean the dead nail as much as possible and expose the healthy regrowth.  This is an important step in making sure that the infection does not return.  We also provide our clients with a complete home care regimen, so that treatments are even more effective and we see results sooner.
