Medical femtosecond laser

Medical femtosecond laser devices are used in dermatology for non-linear high-resolution imaging to obtain non-invasive and label-free optical skin biopsies (multiphoton tomography) as well ophthalmology refractive corneal surgery cataract surgery. Applications of commercial certified multiphoton tomographs include early detection cancer within minutes by two-photon autofluorescence coenzymes melanin second harmonic collagen testing the efficacy pharmaceutical cosmetical products. Goals (i) reduce number physically taken human hospitals research institutions, (ii) optimize personalized medicine, (iii) animal studies pharmacy. Current diagnostic tools surface microscopy with a dermatoscope ultrasound but have poor resolution. Optical coherence tomography confocal reflectance better resolution provide limited information based on changes intratissue index. Multiphoton provides best all clinical methods offer functional such metabolic lifetime imaging. eye treatment replacement mechanical microkeratomes flap generation, UV nanosecond excimer stroma removal, replace, part, scalpel cataracts other diseases. So far, millions treatments been conducted around world. The major disadvantage current medical is high price compared standard devices.
