What is LASIK?

What is LASIK? So LASIK is the most commonly performed laser eye surgery procedure in the world. It is a very well established, very safe, and very effective way of correcting vision so that patients no longer need to wear glasses. The procedure itself takes approximately four to five minutes in total to perform on
each eye.

The Two Steps to the LASIK procedure.

There are two main steps to the LASIK procedure. The first is using what’s called a femtosecond laser to create a very thin flap on the surface of the eye in what we call the cornea.

The second laser is used to sculpt the correct shape lens onto the surface of the cornea in order to correct the vision. And we do this after peeling away the flap so that it is not in the way, and then the deeper part of the
cornea is exposed and we can sculpt the deeper tissues of the cornea with the second laser, which is called the excimer laser.

Once the excimer laser has done the appropriate amount of sculpting, we place the thin flap that we created back on the surface of the eye and give a gentle wash to ensure there’s no particles in between the deeper layer and the flap. And then that’s the treatment completed, taking four to five minutes, and the vision is instantly corrected.

What a patient can expect after surgery.

In terms of what the patient notices, initially they’ll notice the vision is in focus but it’s quite misty and steamy, and over the subsequent 24 hours, the steaminess, the fogginess disappears and the patient has, immediately, sharp vision.
