Laser cutting works by directing the output of a high-power laser most commonly through optics. The laser optics and CNC (computer numerical control) are used to direct the laser beam to the material. A commercial laser for cutting materials uses a motion control system to follow a CNC or G-code of the pattern to be cut onto the material.
The posterior intrastromal plane is created first and the anterior plane second. To allow better separation, the two lenticule faces are cut by the laser head moving in a spiral fashion - conventionally outside in for the posterior face and respectively inside out for the anterior one.

Cryogen spray: sprayed directly onto the skin immediately before and/or after the laser pulse; Air cooling: forced cold air at -34 °C; In essence, the important output parameter when treating hair (and other skin conditions) is power density – this is a combination of energy, spot diameter and pulse duration.
Tattoo ink (or similar agent) is rubbed into a fresh cut to add color or extra visibility to the scar. Most of the ink remains in the skin as the cut heals. This was how tattoos were initially done before the use of needles to inject ink. [17] Skin removal/skinning Skin removal allows for larger markings than simple cutting.
