Femtosecond laser surgery

Definition

Femtosecond laser surgery is a cutting-edge medical procedure that utilizes ultra-short pulses of laser light, typically in the range of femtoseconds (one quadrillionth of a second), to perform precise surgical tasks. This technology allows for highly accurate tissue cutting and manipulation with minimal thermal damage, making it especially valuable in fields like ophthalmic surgery and microsurgery.

5 Must Know Facts For Your Next Test

1. Femtosecond lasers provide greater precision than traditional methods by creating a controlled optical breakdown of tissue, which minimizes collateral damage.
2. In ophthalmic surgery, femtosecond lasers are commonly used for procedures like cataract removal and LASIK, enhancing the safety and outcomes of these surgeries.
3. The rapid pulses of femtosecond lasers can produce bubbles in the tissue that help separate layers without the need for mechanical instruments.
4. This technology has transformed microsurgery by allowing surgeons to perform complex tasks with less strain on delicate tissues and a reduced risk of complications.
5. Femtosecond laser surgery can significantly decrease recovery times for patients due to its minimally invasive nature and precision.
