Laser technology is now applied to many medical fields and has found wide applications in gynecology. Future developments in laser applications in gynecology will probably involve extension of current indications for its use, and the development of other, more sophisticated laser instruments such as the laser hysteroscope that will soon be applied to clinical trials. Familiarity with its mechanics and physical properties can help us safely harness this potentially distractive force and use it effectively as a surgical tool.
