Soft Tissue Laser Surgery is different from Hard Tissue Laser Surgery (bones and teeth in dentistry) and Laser Eye Surgery (eye sight corrective surgeries) by particular types of lasers. Lasers differ from each other by the wavelength of light they produce. The most commonly used surgical laser in soft tissue surgery is the CO2 laser. The CO2 laser wavelength (10.6 micrometers) is highly absorb...

OBJECTIVE To compare the efficacy, adverse effects, and histological findings of erbium:YAG (Er:YAG) and carbon dioxide (CO2) laser treatment in removing facial rhytides. DESIGN An intervention study of 21 subjects with facial rhytides. All participants were followed up for 6 months. The end points of the study were wrinkle improvement and duration of adverse effects. SETTING Academic refer...

The millimeter-wave rotational emission lines (404 − 303 and 505 − 404) of protonated carbon dioxide, HCO2 (HOCO ), has been detected toward the low-mass class 0 protostar IRAS 04368+2557 in L1527 with the IRAM 30 m telescope. This is the first detection of HCO2 except for the Galactic Center clouds. The column density of HCO2 averaged over the beam size (29 ) is determined to be 7.6 × 10 cm, a...

Abstract: In this paper, combining the Maxwell equations with the electron balanceequation, we obtain the inverse braking radiation absorption coefficient in a laser fusioncorona plasma. For a fixed plasma temperature, variations of the absorption coefficientversus the penetration depth into the plasma are illustrated numerically for differentvalues of laser wavelength. ...

Purpose: The purpose of this study was to evaluate a new procedure aimed at lengthening the palpebral fissure to facilitate femtosecond laser-assisted cataract surgery in patients with small eyes. Method: A quick procedure using the CO2 laser was adapted for patients with small eyes undergoing laser-assisted cataract surgery using the Catalys system. The UniPulse CO2 laser (Nidek) was used for ...

Our purpose is to study the efficacy of the alexandrite laser (755 nm) and the fractional laser when treating pigmentary lesions .We use the data of our private office of the last five years (2011-2015) We treated 1000 patients with freckles with alexandrite laser, 200 patients with melasma with fractional laser, 100 patients with post inflammatory hyperpigmentation with alexandrite laser and 6...
