Swan LogoThe DioLite 532 Laser System

The DioLite 532 is an advanced compact laser system for the treatment of vascular and pigmented skin lesions including telangiectasia, rosacea, spider angiomas, spider veins, neovascularization around scars, cherry angiomas, port wine stains, lentigines, dermatosis papulosis nigra, and keratoses, poikiloderma of civatte, and freckles.

The DioLite 532 uses a high-power diode laser to optically pump a laser crystal. This crystal produces 1064 nm of light which is then focused into a frequency doubling crystal to produce a wavelength of 532 nm, one half of the original wavelength.

The clinical versatility of the DioLite 532 and the VariLite allows successful treatment of a variety of vascular and pigmented skin lesions. The strong absorption of the 532 nm wavelength makes the DioLite 532 and the VariLite ideal lasers for treating the following vascular and pigmented lesions.

Vascular

Telangiectasia


Abnormal dilation of the capillary vessels and arterioles commonly present on the face or legs.

Telangiectasia-beforeTelangiectasia-after
    Telangiectasia prior to surgery and immediately
    postoperative without any purpura.

Angiomas

A tumor composed of blood vessels or lymphatic vessels.

  • Spider Angiomas - Slightly raised red papules that resemble the shape of a spider.
  • Cherry Angiomas (Demorgan Spots) - Red spots commonly found on the body.
  • Angiomas-before Angiomas-after
                Spider Angioma, before and after

    Spider Veins

    Small vessels found on the legs (laser best when used on veins measuring less than 0.7 mm in diameter).

    Port Wine Stains

    Reddish-purple superficial hemangiomas that commonly occur as birthmarks.

    Rosacea

    Red facial lesions around the nose and cheeks causing a sunburn look.

    Pyogenic Granuloma

    Pyogenic granuloma is a relatively common benign vascular lesion of the skin and mucosa whose exact cause is unknown.

    Lentigines

    Small, tan to brown macules that can arise on the skin surface or mucous membrane. Usually present on skin that has received excessive sun exposure.

    Lentigines-beforeLentigines-after
    Lentigines prior to surgery and three weeks postoperature.

    Café-au-lait

    Light brown, flat macules that are often first apparent at birth (1 cm - 20 cm diameter).

    FAQs

    Are laser treatments safe?

    Yes. Lasers have been used in medicine for a wide range of treatments since the early 1960s by many specialties. In the hands of a trained healthcare professional, the use of a laser is safe and effective.

    How does the laser work?

    A laser generates an intense beam of light. This beam brings energy to a specific site, through a small handpiece connected to the laser.

    The laser light is absorbed by oxyhemoglobin (bright red blood cells carrying oxygen) and melanin/pigment (black or brown pigment found in the skin) causing decomposition or destruction by heat of unwanted cells while leaving healthy cells intact.

    What is a vascular lesion?

    A vascular lesion is formed by abnormally large or numerous blood vessels located directly under the surface of the skin. These vessels may be visible through the skin or result in a red appearance of the skin.

    What is a pigmented lesion?

    Melanin is the dark pigment present in skin and is produced by melanocytes. Pigmented lesions occur when an abundance of melanocytes are found in the skin. When dark pigment multiplies, it forms freckles, brown age spots and moles.

    What should a patient expect during and after treatment?

    Treatment may vary, depending upon patient characteristics and the area being treated.

    You will be asked to wear special goggles to protect your eyes from the intense beam of laser light.

    You will be placed in a reclined position, depending on the location of treatment. The doctor will use a pencil thin handpiece to direct a beam of laser light to the lesion. In most cases, anesthesia is not required.

    Some patients report feeling a slight stinging sensation during the treatment followed by some redness which usually goes away in 2-4 hours. Some swelling may also be experienced and may last 1-2 days. There will not be any purple skin discoloration or bruised appearance to the treated skin.

    Postoperative care is minimal. Your doctor may ask you to use an anti-bacterial ointment on the treated area for a short period of time and will suggest that you stay out of the sun during the healing process.

    Final treatment results should be evident within 10-14 days after treatment for vascular lesions and within 2-3 weeks after treatment for pigmented lesions. In the meantime, normal daily activities can be resumed with only a slight redness evident at the treatment area.

    What does the laser look and sound like?

    The laser is small - about the size of a VCR. As pulses of energy leave the end of the handpiece fiber, you will hear a soft beeping sound.

    What conditions are treated with the laser?

    Vascular Lesions

    Telangiectasia - facial spider veins caused by a dilation of capillary vessels or arterioles.

    Cherry Angiomas - slightly raised, red lesions

    Spider Angiomas - slightly raised, red spider-like lesions

    Rosacea - red facial lesions around the nose and cheeks causing a sunburn look

    Pigmented Lesions

    Lentigines - a flat, brown spot on the skin present on skin with frequent sun exposure

    Keratoses - slightly elevated pigmented spots often found on the back and hands

    Freckles - a brownish spot on the skin common on people with fair skin

    Dermatosis Papulosis Nigra - small, black marks seen primarily on people of Asian or African descent

    As a patient, what does the laser mean to me? What are the benefits?

    Excellent and consistent outcome minimal to no discoloration, swelling or complications

    Friendly and gentle treatment typically performed without anesthesia or pain

    Simple treatment minimal care before and after treatment

    How will I know if laser treatment is right for me?

    Ask your doctor. After a brief examination, your doctor will be able to determine if laser treatment is appropriate for you.
