How does the Greenlight laser work?
In medicine, lasers have been used for many years in cosmetic surgery and dermatology as 'laser scalpels' to assist in microsurgery. The Greenlight laser has been specifically developed to be used in prostate surgery to vaporise the prostate tissue, thereby removing the inner part of the prostate, enabling a better channel for urinary flow. At the microscopic level, the green colour of the laser is 'attracted' to it's colour opposite i.e. red. This attraction to the red part of the spectrum enables the Greenlight laser to affect red blood cells in particular and so stop bleeding at an early stage. From an operative point of view, this is very advantageous as it makes the Greenlight laser prostatectomy operation a bloodless procedure when compared other lasers or the standard TURP operation.
