How Does LASIK Work?

If your cornea is not shaped in a way that allows light to properly focus on the retina (called a refractive error), you will have blurry vision. LASIK, or the LASIK alternative called PRK, can be performed to correct the corneal shape, allowing light to properly focus and ultimately providing clear vision.

Excimer Laser Technology

Both LASIK and PRK procedures use excimer lasers to reshape the corneal tissue. These are “cool” lasers that generate ultraviolet range power to remove microscopic layers of tissue – approximately 1/10 the width of a human hair. The laser is programmed to remove precisely the amount of tissue needed to achieve the desired visual result for your unique refractive error: nearsightedness, farsightedness or astigmatism.

At Carolinas Centers for Sight, P.C. in Florence the Wavefront Optimized Allegretto Wave® Eye-Q laser is used for LASIK and PRK. Precise laser energy pulses are applied on the periphery of the cornea in order to maintain the cornea’s natural shape while also respecting the cornea’s thickness and curvature. This can reduce the risk of halos, glare and nighttime visual disturbances after treatment. Best of all, the vision results using this technology are superb for most patients.

To be a good candidate for our LASIK technology, you must have the correct corneal thickness and eye health to support the procedure. That’s exactly why we have every LASIK patient undergo an extensive LASIK Consultation, to ensure a highly effective and accurate procedure.
