How LASIK Works

To understand how LASIK works, you first must understand how the eye works. Light is passed through the cornea, through the lens, and then reflects onto the retina. If you have a refractive error, the cornea is misshaped, causing light to refract incorrectly onto the retina.

LASIK is a comparatively simple procedure that has helped millions experience new and improved vision. It has become one of the popular vision correction procedures available because of the short recovery time and effective vision results. The large majority of LASIK patients can expect to reach 20/20 vision or better after undergoing their procedure. To comprehend how these great vision results are achieved, here’s a step-by-step breakdown of ways LASIK works.

Successful LASIK starts with a series of extensive measurements and medical evaluation of your eyes with Dr. Jackson and our skilled technicians. During these consultations, our team will check the cornea’s ability to refract light, the pupil size, the shape of the cornea and the cornea’s thickness. This information is then programmed into a digital treatment plan used during the LASIK procedure. These measurements are necessary to see if you are a good candidate for LASIK surgery.

In step two of the LASIK procedure, the corneal flap is folded back to permit access to the cornea. The Intralase laser quickly and precisely reshapes the cornea. Once complete, the corneal flap is permitted to fall back into place, where it will heal without the necessity for stitches.

In step three, the excimer laser is used to reshape the cornea. Dr. Jackson uses the most advanced technology available – the Technolas 217z™. With the precision of this laser, most patients need a very miniscule section of tissue removed – about the thickness of a human hair – to make the correction. The flap will begin to bond with the tissue immediately with no need for stitches.

The entire LASIK process takes just minutes per eye. Most patients can return to work the next day. LASIK offers many improvements over other refractive surgery procedures. These include little or no post-operative discomfort, immediate vision improvement, and the ability to drive or return to work quickly—sometimes as soon as the next day. Most patients require no corrective eyewear after surgery (although patients over 40 often need reading glasses).
