Cryotherapy is more effective and faster than Q-switched Nd-YAG laser fordepigmentation in universal vitiligo patients
Background: Although cryotherapy has been reported as atechnique for depigmenting residual pigmented patches inpatients with universal vitiligo, Q-switched Nd-YAG lasershave not yet been used for this purpose. The aim of this studywas to compare the efficacy of cryotherapy with that of 532nmQ-switched Nd-YAG laser therapy for depigmentation in patientswith universal vitiligo.Method: Six adult p...
متن کاملTreatment of lentigines by a novel high power diode laser at 755 nm: a case report
The use of high-power diode laser with a wavelength of 755 nm is an effective and safe method for the correction and partial and/or total elimination of pigmented lesions, specifically solar lentigines. This wavelength has yet not been used in diode lasers to treat solar lentigines. Side effects are the usual ones, including darkening and scab formation. Our patient was a 40-year-old woman of C...
متن کاملNd: YAG laser puncture for spontaneous premacular hemorrhage
Herein we report a clinical case of premacular hemorrhage treated with neodymium-doped yttrium aluminum garnet (Nd: YAG laser puncture). A 34-year-old Chinese female was administrated to the clinics with complaints of sudden vision loss of left eye (LE) several days before. The best-corrected visual acuity (BCVA) was reduced to light perception. Fundoscopy showed a large and dense premacular he...
متن کاملInfluence of shielding gas composition on weld structure in pulsed Nd: YAG laser welding
This work studied the effect of additions of carbon dioxide to argon shielding gas on the weld shape and microstructure of ST14 steel in pulsed Nd: YAG laser welding. By additions of carbon dioxide up to 15%,the weld area and depth/width ratio decreases while rising of carbon dioxide up to 25% causes increasing of weld area and depth/width ratio. It is observed that the weld metal microstructur...
متن کاملGrowth, Characterization of Cu Nanoparticles Thin Film by Nd: YAG Laser Pulses Deposition
We report the growth and characterization of Cu nanoparticles thin film of on glass substrate by pulse laser deposition method. The Cu thin film prepared with different energy 50, 60, 70, and 80 mJ. The energy effect on the morphological, structural and optical properties were studied by AFM, XRD and UV-Visible spectrophotometer. Surface topography studied by atomic force microscopy revealed na...
