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 primary objective of this study is to compare the improvement of psoriatic plaques with and without excimer laser (308-nm UVB) treatment, applied in a randomized and blinded fashion, in subjects on acitretin 25 mg or tazarotene gel 0.1% QD. The primary endpoint will be the comparison between the change in NPF score of plaques treated with excimer laser and those treated with sham treatment.
The secondary objectives are to compare the number of excimer light treatments and time necessary to achieve an average lesion assessment score of 0 to 1 in subjects treated with acitretin 25 mg PO or tazarotene gel 0.1% QD, and to evaluate adverse events related to combinations of the study treatments.
Allocation: Randomized, Control: Placebo Control, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Outcomes Assessor), Primary Purpose: Treatment

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 ...
This is a 12-week, open-label, pilot trial evaluating the efficacy and safety of the combination of Clobex® spray with excimer laser therapy as the initial treatment of generalized plaque...
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 treat...
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...
This study aims to explore the expression of RORγt, BATF, and IL-17 in Chinese vitiligo patients with 308 nm excimer laser treatment. One hundred and sixty-four vitiligo patients treated with 308 nm ...
To evaluate long-term results of sequential customized therapeutic keratectomy (SCTK) in highly aberrated corneas with apical scars consequent to hyperopic excimer laser refractive surgery.
Metal cluster are promising nontoxic candidates in optoelectronics and photonics. Recently, clusters with appropriate molecular ligands have been demonstrated to be uniquely suitable as subnanometer b...

Studying the complexes of inorganic nanoparticles - organic dye molecules is of great importance for their theranostics application. In this paper, we report gadolinium-yttrium orthovanadate nanoparti...
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.
Gas lasers with excited dimers (i.e., excimers) as the active medium. The most commonly used are rare gas monohalides (e.g., argon fluoride, xenon chloride). Their principal emission wavelengths are in the ultraviolet range and depend on the monohalide used (e.g., 193 nm for ArF, 308 nm for Xe Cl). These lasers are operated in pulsed and Q-switched modes and used in photoablative decomposition involving actual removal of tissue. (UMDNS, 2005)
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 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 common genetically determined, chronic, inflammatory skin disease characterized by rounded erythematous, dry, scaling patches. The lesions have a predilection for nails, scalp, genitalia, extensor surfaces, and the lumbosacral region. Accelerated epidermopoiesis is considered to be the fundamental pathologic feature in psoriasis.
