Top 10 Commonly Confused Words in Laser Medicine

Top 10 Commonly Confused Words in Laser Medicine 1. Wavelength vs. Frequency Wavelength and frequency are two fundamental concepts in laser medicine. While wavelength refers to the distance between two consecutive peaks of a wave, frequency represents the number of wave cycles per second. Remember, wavelength determines the laser's tissue penetration, while frequency affects its energy. So, they're distinct but interconnected. 2. Ablation vs. Coagulation Ablation and coagulation are often used interchangeably, but they have different meanings. Ablation refers to the removal of tissue, while coagulation involves clotting or sealing blood vessels. In laser medicine, we may use ablation to remove a tumor, while coagulation helps control bleeding during a procedure. 3. Photothermal vs. Photochemical Photothermal and photochemical reactions are crucial in laser medicine. Photothermal reactions involve the conversion of light energy into heat, which can be used for tissue ablation. On the other hand, photochemical reactions occur when light energy triggers a chemical change in a substance. Both have their applications and mechanisms. 4. Incision vs. Excision
