Laser Fungus Procedures


Nail fungus, also called onychomycosis, is a common condition estimated to affect up to 10% of the population worldwide. It can cause nails to become yellow or discolored. As the infection advances the nail can become thick, brittle and separate from the nail bed. It can also cause pain when wearing shoes or walking.

This page provides information about the causes of nail infections and available treatment options. The benefits, disadvantages and risk of each treatment is discussed. You should discuss your medical condition and treatment with your doctor.

Dermatophytes are the fungi most commonly responsible for causing this condition. They are specialized organisms that live off of keratin which is the main component of nails and skin. The most common fungi that cause nail infection disease are Trichophyton rubrum, Trichophyton mentagrophytes, and Candida albicans. Everyone is at risk for infection because fungus is present everywhere in the environment.

Where does nail infection come from?
Nail infection is caused by contact with dermatophytes which are everywhere in our environment. Common sources of infection include swimming pools, public showers, gyms and nail spas. Tight fitting shoes and nail trauma can also lead to infection. Genetic susceptibility, poor health, weakened immune system from chemotherapy and increasing age are also factors that increase the risk of nail infection.

  • Nails separated from the underlying skin
  • Buildup of debris (nail fragments, skin) under the nail
  • White spots or streaks on the nail surface

What treatments are available for nail infections?
Current treatment options for nail infection include oral drugs, topical drugs and laser. No single treatment is effective in all patients and there are risks and benefits associated with each one. Be
sure to discuss all your treatment options with your doctor.

Oral drugs can be very effective in eliminating nail infections and restoring clear nails. The drugs must be taken for 12 to 14 weeks and may cause side effects including headache, diarrhea, upset stomach and skin rash. Serious side effects include risk of liver damage and heart failure. Monthly blood tests may be required to monitor liver function. These drugs are not used for patients in poor health or who have liver disease.

Topical drugs are less effective in treating nail infections and restoring clear nails. The drugs are applied directly to the nails daily for up to 12 months. In some patients, the drug is ineffective because it cannot pass through the nail to reach the infection. There are no significant side effects.

Laser procedures are effective in eliminating nail infections and restoring clear nails. Most patients experience at least some improvement. During the procedure most patients experience a warm feeling in their toes. A clinical study reported no adverse effects related to the laser.

How does GenesisPlus work?
Laser light from GenesisPlus passes through the nail and the surrounding tissue. The laser light is absorbed by pigment in the fungi, which causes the pigment to heat, and this heat kills or damages the fungal organism. This can result in your nail growing normally.

What is the Success Rate of the Laser Procedure?
According to the most recent information on laser treatment of fungal nail infections, the improvement is about 85 percent. Results my vary based on the number of treatments, compliance, follow-up visits and application of topical anti-fungal medication after the laster treatment to prevent re-infection.

Will the fungus come back?
Your nail infection should improve following the procedure but you will need to continue with home care techniques to reduce recurrence of the infection as advised by your doctor. There is a chance of re-infection because the fungus is present everywhere in the enviroment.
