NuSiteTM Advanced Surface Ablation (PRK)
Laser Vision Correction Surgery has two forms, surface laser (PRK, LASEK, epi-LASIK and NuSite™ Advanced Surface Ablation) and LASIK. Photorefractive Keratectomy (PRK) was the original refractive procedure utilizing the excimer laser to reshape the surface of the cornea, correcting nearsightedness, farsightedness and astigmatism. Later, surgeons began making a flap in the cornea prior to the laser treatment to speed recovery and decrease pain (LASIK). This procedure quickly became the predominant refractive procedure in the world. However, some patients with thin corneas, high nearsightedness or surface problems are not eligible for LASIK and will do better with surface ablation techniques.
Now with NuSite™ Advanced Surface Ablation (essentially an updated version of PRK) the speed of recovery and pain control have markedly improved, approaching the same comfort level as LASIK in most cases. The NuSite™ procedure utilizes the Moria Epi-K system to remove the epithelium (top layer of cells) prior to reshaping the cornea with VISX Star S4 IR excimer laser. This method has been shown in studies to produce less visual aberrations, faster healing times and faster visual recovery than all other surface ablation procedures.
The long term visual outcomes, quality of vision and safety are excellent in both Z-LASIK and NuSite™ Advanced Surface Ablation. So whichever procedure is right for you, you can be assured that the doctors at Virginia Beach Eye Center will be using the latest technology to maximize your visual results.
