Do physicians use laser during lasik surgery?

Yes. Yes, the excimer laser is used to reshape the cornea in order to correct the underlying refractive error.
Always. Lasik, by definition, is a procedure where a laser is used to change the shape of the cornea.
Yes. Lasik is a two step procedure. The first step can be completed with a laser or instead with a bladed instrument called a microkeratome. The second step of lasik is always completed with a laser.
Yes and more! We also use the newest lasik techniques that use a laser to make the corneal flap rather than a blade. This generally has better outcomes in terms of vision and patient discomfort. This is called intralase.
Yes. Most lasik surgeons use a femtosecond laser to create the flap and an excimer laser to eliminate the prescription.
