FEMTOLASER: FEMTOSECOND LASER
Femtosecond laser, also known as femtolaser, is an instrument that emits infrared radiation of the duration of a femtosecond. The femtosecond is a fraction of time of a millionth of a billionth of a second. This laser emits several spots of this duration in the external layer of the cornea and, as a consequence, generates gas bubbles within the corneal tissue. The repetition of these spots by the number desired by the surgeon, set in the computer that manages the laser itself, will create macroscopic effects such as, for example, a corneal flap, corneal incisions or cuts useful in order to perform a keratoplasty, lamellar or penetrating. It is clear how this laser is capable of producing optical correction fpr vision defects (cuts) but also able to produce propedeutical effects for other surgical actions as the creation of a flap (to be used in the course of an all-laser Lasik, i-Lasik), or to cut the whole cornea to proceed to a keratoplasty (corneal transplantation). Femtosecond laser is also used in some stages of cataract surgery.
The therapeutic and surgical potential of this laser is still, for the most part, to be discovered.
