The Medlite IV Q-Switched Nd:YAG laser was produced from 1998 to 2002 by Continuum Biomedical. The Medlite IV continues to be a great investment for any aesthetic practice as it performs extremely well.
Q-Switched lasers work by emitting very short pulse-widths in a matter of nanoseconds. The resulting ablation is called photacoustic. In simple terms the resultant energy released by the laser is like a mini sonic boom that disrupts the intended target mechanically. This is in contrast to lasers that deliver light energy which heats their target also known as photothermal ablation.
The laser system operates at a 532 nm green wavelength with its primary wavelength being 1064 nm. Dye handpieces can be utilized to achieve 585nm wavelength and 650nm wavelength. The Medlite IV when operated at 1064nm wavelength is intended for dark in tattoo removal. It can also be used to treat Nevus of Ota and for lightening/removal of unwanted hair. When operated at 532nm wavelength, the primary use is the removal of light ink tattoos and treatment of vascular lesions.
The Medlite IV comes with a MultiSpot handpiece. Following are the wavelength specifications as delivered by the Medlite IV:
- 2mm @ 532nm
- 3mm @ 532nm and 1064nm
- 4mm @ 532nm and 1064nm
- 6mm @ 532nm and 1064nm and
- 8mm @ 1064nm
Key things to note when using the Medlite IV laser system:
- Always wear protective eyewear – this includes everyone in the room during the treatment process.
- Every three (3) months the laser should be calibrated by a professional to ensure it is performing to specification..
- The heads should be cleaned after every use.
