Onychomycosis: fungal nail infection treatment

mycose des pieds

Onychomycosis, or mycosis of the nails, are frequent problem and difficult to treat, the treatment requires several months. Often the drugs and topical medical treatments are ineffective because the microorganisms responsible develop mechanisms of resistance, vis-à-vis these drugs which, moreover, diffuse poorly in the nail because of subungual hyperkeratosis, thus these topical treatments themselves can cause hyperkeratosis ( blocked pores ) underneath the nail.
Onychomycoses are benign diseases caused by fungi, which can, however, cause complications such as discomfort to the foot (athlete’s foot), which nonetheless leads to complications such as making it painful to put shoes on, or the fungal infection spreading to other parts of the body, or to other people, and causing serious problems, such as ulcers and reinfection amongst diabetics.



Vascular Laser

Prior to the laser session it is essential to perform a mycological sampling in a specialized laboratory to confirm the diagnosis (50% of onychopathies are not fungal!).
The nail should be prepared by a podiatrist: reducing its thickness to one millimeter to allow the laser energy to reach the subungueal tissue.
The laser beam, passing over the nail, causes the fungus temperature to rise, destroying the fungus without damaging surrounding healthy tissue. It is important to note that the nail will grow back normally.
The treatment is very painless, however, the patient may feel a slight senseation of heat. Moreover all nails are treated,  as well as the surrounding skin and in-between the toes. This will get rid of any lurking ‘sub-clinical’ infection (an infection which has not yet developed any clinically recognized signs) which could cause reinfection.
1-3 sessions are required, with 1 or 2 weeks in between each session.

After the treatment, you must follow certain steps to avoid reinfection:
Apply an anti-fungal treatment twice a day for two weeks to the skin and the sides of the feet; after two weeks, you must apply the cream once a day for a further two months.
In the evening, spray the inside of your shoes with an anti-fungal spray.
Avoid walking barefoot in public spaces ( e.g. swimming pools, sports halls and in the sauna ).
Disinfect your nail care kit (scissors, clippers etc.)
Change your shoes regularly.
Cut out factors, which encourage fungal infection (heat and moisture, heavy sweating, constant wear of closed-toe shoes, smoking, biting nails).

Following the treatment there is no down time, and it is possible for the patient to wear shoes straight away.  Skin around the treated area will be red and slightly puffy for 24 hours after the treatment.


After the laser session, the evolution is as follows:

- Fungal infection/Mycological cure rate of 85.5%.
- Gradual lightening of the nail in several months, it is the time necessary for the regrowth of the healthy nail (the regrowth is on average 1 mm per month). For the fingers it takes 4 to 6 months, for the toes it takes 9 to 12 months.







To treat my toenail mycosis, Doctor Romano offered laser sessions (4 sessions), the results were fast. Thank you Doctor.


In the summer, I didn’t dare wear sandals anymore because of my toenail mycosis. I thank Doctor Romano for finding a solution to treat them. I am very satisfied with the result.


I consulted Doctor Romano for feet mycosis, she did laser sessions. I can finally stay barefoot in the house. Very professional doctor.


I am very satisfied with the treatment done by Doctor Romano to treat my mycosis, I am no longer neurotic about my feet. Thanks again.
