The Value of Understanding the Science
The first law of photochemistry states biologic effects of laser-tissue interaction can only transpire in the presence of a photo-receptor molecule or chromophore; a molecule capable of absorbing the photonic energy being emitted. Generally speaking, the greater the absorption, the greater the interaction, and in the case of biologic soft tissue, the 980nm high absorption diode laser selectively targets WATER as water comprises > 70% of soft tissue.
Higher water absorption means more efficient and effective ablation of the prostate hence treatment times are dramatically reduced compared to alternative wavelengths. Shorter treatment time means less collateral thermal effect on surrounding healthy tissue leading to faster recovery and less post-operative discomfort. Finally safety is paramount as higher absorption in the target means less penetration and more control at the fiber-tissue interface, eliminating the concern of inadvertent interaction with healthy surrounding healthy tissue.
With high absorption in both water and hemoglobin this wavelength is optimized for performance resulting in optimal tissue ablation, durable coagulation and enhanced visibility.
