We carried out a PubMed search using following terms “lasers, IPL, melasma, PIH”. with ytterbium, erbium, thulium or holmium doping (see below). First of all the nurse will test your vision. 654. Laser fibers of 150 µm length were. ObjectiveTo compare the efficacy and safety of non-fractional picosecond Nd:YAG laser. With the increase of time, the temperature in Nd:YAG rod pump end increases linearly. Compared to other lithotripsy techniques, the. The pristine spot size of the laser shot is about 6 mm in diameter with a typical energy of 700 mJ, corresponding to an energy density of about 2. The Abraham Nd:YAG laser: Increases the convergence angle to 24 degrees from 16 degrees. 2 in. Er:YAG crystal has the potential to realize higher average power output of 3 μm MIR laser. Abstract. However, there are some risks and side-effects which includes an increase in floaters, raised intraocular pressure, inflammation, haloes/glare, lens damage, retinal tear/detachment. A new slab configuration is designed based on the traditional Yb:YAG Total-Reflection Active-Mirror (TRAM) slab laser. What is YAG laser vitreolysis? YAG Laser Vitreolysis (laser eye floater removal) is a highly effective, outpatient procedure that involves the use of a nano-pulsed YAG laser to vaporize eye floaters. Results: Spontaneous resolution of a YAG laser–induced macular hole in a pediatric patient. However, iatrogenic intraocular lens damage is a relatively common side effect that happens due to inappropriate focusing during the procedure. Wrinkle improvement. 1986 Mar;12(2):162-70.
