This procedure can be used to correct defective vision in the eye, i. In contrast to conventional LASIK, the thin corneal flap is produced using the high-precision femtosecond laser rather than mechanically — for example with a computer-controlled precision blade.
First, a corneal lamella known by the medical term ''flap' is prepared using this laser. To do this, the femtosecond laser sets millions of tiny air bubbles at a precisely defined corneal depth, which then expand and separate the layers of tissue from each other. It is then possible to fold back the corneal lamella prepared in this way. Tissue is then removed in the deeper layer of the cornea that is now exposed using what is known as the excimer laser.
This changes the refractive power of the cornea, therefore also correcting the refractive error. The term 'excimer lasers' refers to a gas laser that can generate electromagnetic radiation in the ultraviolet wavelength range. In the case of refractive errors i.
The shape of the eye or cornea or age-related lens stiffness may limit the focusing capacity of the eye. The difference lies in the way in which the flap i. Patients who suffer from astigmatism or who are near-sighted or far-sighted should first talk to their ophthalmologist about laser eye surgery and other alternative treatment methods.
