To determine the optimal treatment frequency of 308-nm excimer laser for vitiligo and identify the key clinical variable(s) associated with the treatment efficiency under the optimal treatment frequency.
Prospective, randomized, comparative study among groups of vitiligo patients treated with 308-nm excimer laser, with the limitation of no follow-up.
Vitiligo patients were treated with 308-nm excimer laser for 20 sessions at different frequencies (0.5×, 1.0×, 2.0× and 3.0× weekly). Treatment protocols adapted the dose to the lesions and not to the minimal erythemal dose. Treatment efficacy was blindly evaluated by 2 independent physicians. Re-pigmentation rate was graded on a 6-point scale. The onset of re-pigmentation of vitiligo lesions was evaluated after 5 treatment sessions. The differences between Group 0.5×, 1.0×, 2.0× and 3.0× linking different clinical variables were assessed.

308 nm excimer lamp and 308 nm excimer laser have both provide interesting results in treating vitiligo. They have the same wavelength but the type of emission of the photons is different....
Although vitiligo is difficult to cure, recurrences are frequent after treatment, and many patients suffer from concerns about recurrence as well as disease. Psoriasis, another indication ...

A Prospective, Randomized, Multi Center Clinical Comparison of Fellow Eyes Undergoing Lasik Using the Wavelight Allegretto Wave™ Excimer Laser in One Eye and the Amo/Visx Customvue™ or the Ladarvision 4000 Excimer Laser System in the Contralateral Eye
The purpose of this study is to compare LASIK outcomes using the WaveLight ALLEGRETTO WAVE™ wavefront guided or optimized excimer laser treatment with the AMO/VISX CustomVue™ and the L...
The hypothesis of this study is that excimer (308-nm UVB) laser added to either tazarotene 0.1% gel or acitretin 25 mg daily will lead to improved efficacy of these treatments alone. The ...
A 308-nm excimer laser (EL) has been widely used to treat patients with localized vitiligo. However, data are rare on the influence of EL treatment on the risks of skin cancer. To evaluate the skin ca...
To report the outcomes of laser in situ keratomileusis (LASIK) for hyperopia using the Triple-A ablation profile with the MEL 90 excimer laser (Carl Zeiss Meditec, Jena, Germany).
Vitiligo is a disease pathologically characterized by specific damage to melanocytes. The aim of this study was to explore the mechanism underlying CO2 fractional laser treatment of vitiligo by detect...
The study aims to compare the impact of non-mechanical excimer laser-assisted (EXCIMER) and femtosecond laser-assisted (FEMTO) trephinations on graft endothelial cell density (ECD) and graft thickness...
Excimer laser coronary angioplasty (ELCA) is a unique revascularization modality that can vaporize plaque and thrombus. Compared to thrombus aspiration therapy, ELCA is reported to provide better micr...
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).
A surgical procedure to correct MYOPIA by CORNEAL STROMA subtraction. It involves the use of a microkeratome to make a lamellar dissection of the CORNEA creating a flap with intact CORNEAL EPITHELIUM. After the flap is lifted, the underlying midstroma is reshaped with an EXCIMER LASER and the flap is returned to its original position.
A type of refractive surgery of the CORNEA to correct MYOPIA and ASTIGMATISM. An EXCIMER LASER is used directly on the surface of the EYE to remove some of the CORNEAL EPITHELIUM thus reshaping the anterior curvature of the cornea.
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.
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.
