Ablative fractional lasers were introduced for treating facial rhytides in an attempt to achieve results comparable to traditional ablative resurfacing but with fewer side effects. However, there is conflicting evidence on how well this goal has generally been achieved as well as on the comparative value of fractional CO2 and Er:YAG lasers. The present study compares these modalities in a randomized controlled blinded split-face study design:
28 patients were enrolled and completed the entire study. Patients were randomly assigned to receive a single treatment on each side of the peri-orbital region, one with a fractional CO2 and one with a fractional Er:YAG laser. The evaluation included Fitzpatrick wrinkle score, profilometric measurement of wrinkle depth (both before and 3 months after treatment) as well as assessment of side effects and patient satisfaction (1, 3, 6 days and 3 months after treatment).

The primary objective of this randomized, split-face, controlled study is to compare the efficacy and safety of a erbium-doped 1,550-nm non-ablative fractional laser and a bipolar fraction...
Fractional carbon dioxide laser treatment in postburn scars is safe and effective, but high rates of hypochromia (35 percent) have been described in patients with skin phototypes V and VI after 2 mont...
Rhinophyma results in nasal deformity, which may lead to significant distress, embarrassment, social isolation, and low self-esteem. Fractional carbon dioxide (CO2) laser treatment is a simple, non-in...
Fractional photothermolysis is creation of microscopic thermal zones of controlled depth, width and density. Microneedling is a simple treatment modality to reduce striae distensae.
Dowling-Degos disease (DDD) is a rare autosomal-dominant genodermatosis with limited treatment possibilities. Although the efficacy of ablative laser therapy has been reported, we sought to examine th...
Misperceptions have persisted regarding scanning full-field erbium laser that have caused it to be overshadowed by fractional ablative resurfacing. This can lead to sub-optimally treating the periocul...
A technique utilizing a laser coupled to a catheter which is used in the dilatation of occluded blood vessels. This includes laser thermal angioplasty where the laser energy heats up a metal tip, and direct laser angioplasty where the laser energy directly ablates the occlusion. One form of the latter approach uses an EXCIMER LASER which creates microscopically precise cuts without thermal injury. When laser angioplasty is performed in combination with balloon angioplasty it is called laser-assisted balloon angioplasty (ANGIOPLASTY, BALLOON, LASER-ASSISTED).
Treatment using irradiation with LASER light of low power intensity so that the effects are not due to heat, as in LASER THERAPY. These non-thermal effects are thought to be mediated by a photochemical reaction that alters CELL MEMBRANE PERMEABILITY, leading to increased mRNA synthesis and CELL PROLIFERATION. Low-level laser therapy has been used for a wide variety of conditions, but most frequently for wound healing and pain control.
Techniques using laser energy in combination with a balloon catheter to perform angioplasty. These procedures can take several forms including: 1, laser fiber delivering the energy while the inflated balloon centers the fiber and occludes the blood flow; 2, balloon angioplasty immediately following laser angioplasty; or 3, laser energy transmitted through angioplasty balloons that contain an internal fiber.
Fragmentation of CALCULI, notably urinary or biliary, by LASER.
Techniques using a laser to cut away and harvest a specific cell or cluster of cells from a tissue section while viewing it under the microscope.
