The first and most important aspect to understand is that LASIK is not performed with just one technique or technology. At NVISION we utilize an all-laser approach, creating the corneal flap with a state-of-the-art Femtosecond Laser, which is significantly safer than a mechanical blade approach used at some other clinics. More importantly, NVISION utilizes highly advanced excimer lasers with anti-glare patterns to provide not only incredible day vision quality but also night vision. NVISION surgeons have also been leaders in both wavefront-guided and topography-guided treatments.
