Background: Dry eye disease (DED) is a complex ocular surface inflammatory disorder with a multifactorial etiology. Therapies such as intense pulsed light (IPL) and heated eye mask (HEM) have been reported to improve the tear film lipid layer (TFLL) and signs and symptoms of DED. Methods: This randomized study aimed to compare the effects of IPL combined with HEM (IPL+HEM) group, IPL group, and control group in participants with evaporative DED. All participants were examined at baseline (D0), day 21 (D21), day 42 (D42), and day 84 (D84) for noninvasive tear breakup time (NITBUT), TFLL, corneal conjunctival staining (CS), meibomian gland quality (MGQ), meibomian gland expressibility (MGEx), and Ocular Surface Disease Index (OSDI)...

BACKGROUND: Cutaneous leishmaniasis (CL) is a common parasitic disorder that is endemic in many countries. There is no completely effective treatment for this condition, but pentavalent antimony compounds are regarded as the main treatment. Different laser types have been used for treatment of CL with variable success but to our best knowledge, there is no published paper regarding use of intense pulsed light (IPL) for treatment of CL. MATERIALS AND METHODS: In this randomized, single-blind clinical trial study, we compared the efficacy of intralesional glucantime alone versus intralesional glucantime plus weekly IPL for treatment of 54 patients with confirmed cutaneous leishmaniasis for a maximum of eight weeks as a randomized, clinical trial...

BACKGROUND: Although pulsed dye laser (PDL) is the treatment of choice for port-wine stains (PWS), clinical resistance to PDL has been observed in 20-30% of cases. Several alternative treatment modalities have been introduced; however, there is still a lack of definite recommendations regarding the optimal treatment for difficult-to-treat PWS. OBJECTIVE: We aimed to systematically review and analyze the comparative effectiveness among treatments for problematic PWS...

Hair removal with lasers and intense pulsed light (IPL) is considered safe. However, data on the efficacy and safety of these procedures specifically in the pediatric population remain sparse.

There was a significant increase in melanin levels across all melasma types, an increase in erythema in the dermal type, and an increase in sebum production in the epidermal type...

BACKGROUND: Primary axillary hyperhidrosis (PAH) affects 1-5% of the world's population who has an unmet need for improved treatments. The heating of sweat glands with specific microwave therapy has shown promising results, yet, treatment with widely available devices such as long-pulsed Neodymium Yttrium Aluminum Garnet (Nd:YAG) lasers, diode lasers or Intense Pulsed Light (IPL) may serve as pragmatic alternatives. OBJECTIVES: To compare sweat secretion of treated versus untreated contralateral control axilla 1-3 months after one session of Nd:YAG laser or IPL in patients with PAH...

PURPOSE: To assess the effect of neodymium:yttrium-aluminum-garnet (Nd-YAG) laser procedure on the choroid and retina in patients who developed posterior capsular opacification (PCO) after cataract surgery. METHODS: In this study, 32 eyes of 30 patients who underwent Nd:YAG laser treatment for PCO were evaluated. Visual acuity (VA), intraocular pressure (IOP), central macular thickness (CMT) with optical coherence tomography device (OCT), ganglion cell layer (GCL), inner plexiform layer (IPL), retinal nerve fiber layer (RNFL) and subfoveal choroidal thickness (SCT) were measured...

Rare earth ores are complex in composition and diverse in mineral composition, requiring high technical requirements for the selection of rare earth ores. It is of great significance to explore the on-site rapid detection and analysis methods of rare earth elements in rare earth ores. Laser induced breakdown spectroscopy (LIBS) is an important tool to detect rare earth ores, which can be used for in situ analyses without complicated sample preparation. In this study, a rapid quantitative analysis method for rare earth elements Lu and Y in rare earth ores was established by LIBS combined with an iPLS-VIP hybrid variable selection strategy and partial least squares (PLS) method...

INTRODUCTION: Facial erythema can be seen in many patients. Despite various clinical trials exploring the effect of intense pulsed light (IPL) in treating facial erythema, comprehensive evidence about the specific outcomes remains lacking. EVIDENCE ACQUISITION: We searched published studies in the Web of Science, PubMed, Embase, and Cochrane Library databases based on established inclusion criteria. We calculated odds ratios (OR) to evaluate the effectiveness of IPL in patients with facial erythema...

INTRODUCTION: Phototherapy has been one of the first and still frequently used treatment modality for psoriasis.
