Blue laser vaporization alleviates lower urinary tract symptoms while preserving sexual function in patients undergoing benign prostatic hyperplasia (BPH) surgery, according to a study. Zun-Jie Hu and colleagues assessed the impact of 450-nm blue laser vaporization on sexual function in 67 patients (median age, 65 years) undergoing BPH surgery and followed for three months. The researchers found that blue laser vaporization significantly improved International Prostate Symptom Score, quality of life, and International Consultation on Incontinence Modular Questionnaire for Male Lower Urinary Tract Symptoms (ICIQ-MLUTS) scores. Blue laser vaporization was also significantly associated with a reduction in postvoid residual volume. There...

REVIEW ARTICLE The strongly localized interaction process of ultrashort laser pulses with tissue makes femtosecond lasers a powerful tool for eye surgery. These lasers are now routinely used in refractive surgery and other forms of surgery of the anterior segment of the eye. Several clinical laser systems also offer options for corneal grafting and the potential use of ultrashort pulse lasers in glaucoma surgery has been the object of several recent studies which have shown promising results.While devices aimed for interventions in clear tissue may be based on available solid state or fibre laser technology, the development of tools for...

BETHESDA, Md., June 17 — Almost every Thursday during the academic year, a bus carrying a dozen or so Naval Academy midshipmen leaves Annapolis for the 45-minute drive to Bethesda, where Navy doctors perform laser eye surgery on them, one after another, with assembly-line efficiency.

Unlike in the civilian world, where eye surgery is still largely done for convenience or vanity, the procedure's popularity in the armed forces is transforming career choices and daily life in...
