The Greenlight Laser

It is the particular wavelength of the laser light that gives this laser its name and more importantly its unique attributes. The green light of the laser is avidly absorbed by red; the prostate gland has a very good blood supply and may be considered biologically red. The prostate gland, therefore, is an excellent target for the greenlight laser in achieving vapourisation of tissue. The laser is able to vapourise prostate tissue, but because of only shallow conduction (or scattering) of the laser beyond the zone of vapourisation, sufficient surrounding coagulation means that the procedure is essentially bloodless.

'Vapourisation of the prostate using the Greenlight laser (Photoselective vapourisation of the prostate – PVP) is the only true surgical treatment of the procedure where there is an insignificant risk of heavy bleeding or the need for a blood transfusion'

The evolution of the Greenlight laser over the last 15 years has been based on technology allowing ever higher power delivery, hence more efficient vapourisation . The 80 Watt Greenlight PV system was introduced into the UK in 2002. This machine featured a unique rapidly pulsed generator that meant almost continuous delivery of the 80 Watts of laser energy. In 2006/7, this was replaced by the High Performance System, The Greenlight HPS. This machine was capable of delivering 120 Watts of continuous laser energy allowing much faster vapourisation of prostate tissue.

'The Greenlight XPS laser system in combination with MOxY fibre is twice as efficient as this last model, more power being delivered to a wider surface area'

This means quick procedures with shorter anaesthetics and better than ever tissue removal, whilst maintaining the unique, exceptional quality of ensuring none or very minimal bleeding during the procedure.
