Clinical Studies

Founded on Science Supported by a Body of Clinical Evidence

The GreenLight PV® laser has proven to be the ideal tool for soft tissue vaporization and coagulation because “Green” is highly absorbed by oxyhemoglobin, but not by water. A body of clinical evidence supports the safety, efficacy and durability of the PVP procedure using the GreenLight PV laser system.
