Intravenous tissue plasminogen activator is the only proven therapy for acute ischemic stroke. Not enough patients are eligible for treatment and additional new therapies are needed. Recently, laser technology has been applied to acute ischemic stroke. This noninvasive technique uses near-infrared wavelengths applied to the scalp within 24 h of symptom onset. The mechanism is incompletely under...

With the advent of such systems as the airborne laser and advanced tactical laser, high-energy lasers that use 1315-nm wavelengths in the near-infrared band will soon present a new laser safety challenge to armed forces and civilian populations. Experiments in nonhuman primates using this wavelength have demonstrated a range of ocular injuries, including corneal, lenticular, and retinal lesions...

OBJECTIVE To compare the efficacy and safety of approved treatments for macular oedema secondary to branch retinal vein occlusion (BRVO). DESIGN Randomised controlled trials (RCTs) evaluating the efficacy and safety of approved treatments for macular oedema secondary to BRVO were identified from an updated systematic review. SETTING A Bayesian network meta-analysis of RCTs of treatments for...

Fractional continuous wave CO2 laser resurfacing is used to improve photodamage, wrinkles, and acne scarring by surface ablation and by using heat to activate natural collagen production and dermal remodeling. In this study, the author examined the efficacy and safety of nonincisional continuous wave fractional CO2 laser blepharoplasty in the upper lid. Standard lid measurements including margi...

Stress in laser cladding coating is an important factor affecting the safe operation of remanufacturing components. Ultrasonic testing has become a popular approach in the nondestructive evaluation of stress, because it has the advantages of safety, nondestructiveness, and online detection. This paper provides a review of ultrasonic testing for stress in remanufacturing laser cladding coating. ...

The latest technical improvements in the surgical armamentarium are remarkable. In particular, advancements in the urologic field are so exceptional that we could observe the flare-up of robot-assisted laparoscopic radical prostatectomy for prostate cancer and laser prostatectomy for benign prostatic hyperplasia (BPH). Photoselective vaporization of the prostate (PVP) and holmium laser prostate...

Since first being developed in 1960, the LASER, an acronym for Light Amplification Stimulated Emission of Radiation, has become a commonplace device in industry, commerce, entertainment and medicine. Laser pointers – the hand-held, pen-like devices that project a beam of laser light – are rapidly replacing the traditional wooden pointers used by lecturers during presentations. However, these po...

The introduction of femtosecond lasers to cataract surgery has been the major disruptive technology introduced into ophthalmic surgery in the last decade. Femtosecond laser cataract surgery (FLACS) integrates high-resolution anterior segment imaging with a femtosecond laser allowing key steps of cataract surgery to be performed with computer-guided laser accuracy, precision, and reproducibility...

Edward Buckley (SID Member) Abstract — Scanned-beam projection systems have attracted much interest recently, with claimed advantages including power efficiency and potential miniaturization consistent with embedding in mobile devices. However, the laser-safety classification and concomitant performance implications, which are arguably the most important issues pertaining to this technology, re...

BACKGROUND Safety of cosmetic procedures in pregnant women has not been extensively studied. Maternal and fetal health risks are important to consider in any procedure performed. With the increasing popularity of cosmetic procedures, dermatologic surgeons will be faced with scenarios necessitating knowledge regarding the safety of such procedures during pregnancy. Furthermore, dermatologic surg...
