Medical Missions Around the World

Do you have discolored thick toenails? Are you embarrassed to show your nails in public? If so, then Mercado Foot & Ankle Center can help. One of the first in the area to use laser therapy to treat fungal discolored nails, Dr. Mercado successfully treats Onychomycosis painlessly with this new technology

Before the advent of laser treatment, the only products available to treat this condition were strong medications that can cause liver damage and largely ineffective liquids and creams. The laser therapy is highly effective treating the fungus at the source.

What to expect

While lasers may seem scary to some, they use safe light energy and are used daily for cosmetic procedures. Now that same state-of-the-art technology can be used to treat toe nail fungus. This safe and painless laser treatment irradiates the fungus and kills it without any damage to surrounding skin.

You can visit our office for a consultation to determine if you are a candidate for  laser treatment. The laser treatment takes about 20 minutes to treat both feet.  As each toe is treated by the laser, you will feel a mild, warming sensation. Many times only one treatment is necessary.

The laser treatment potentially consists of up to 3 sessions beginning at day 1, 6 weeks and 12  weeks if  necessary. Shoes and nail polish can be worn immediately after treatment. We will discuss post treatment care to avoid fungal re-infection.

Significant improvement can be seen over one year, but many times you will notice results within 3-6 months, depending on how quickly your toenails grow. New, clear growth begins to appear at the bottom portion of your nail as the diseased portion of your nail grows out.
