Lasers are used in medicine in various ways, including cutting through tough tissue, scanning for information, and performing delicate surgery. The specific use depends on the medical procedure and the type of laser being used.
To cut through tough tissue, lasers are focused and directed onto the targeted area. The intense, concentrated light energy vaporizes or coagulates the tissue, allowing for precise and controlled incisions. This can be particularly helpful in surgeries where traditional surgical tools may be too invasive or risky.
To scan for information, lasers are used in diagnostic procedures such as laser-based imaging techniques. For example, in laser scanning microscopy, a laser beam is used to scan a sample, producing high-resolution images or 3D reconstructions. This can help in understanding cellular structures, identifying abnormalities, or guiding further treatment decisions.
To perform delicate surgery, lasers are used in procedures such as laser-assisted in situ keratomileusis (LASIK) for vision correction or laser ablation for the removal of tumors or lesions. The focused laser energy allows for precise tissue removal or reshaping with minimal damage to surrounding healthy tissue.
In summary, lasers in medicine have diverse applications, ranging from cutting through tough tissue to performing delicate surgeries and providing diagnostic information. The choice of laser and its specific use depend on the medical procedure being performed.
