With recent advancements, newer LASIK (Laser-Assisted Keratomileusis) ablation profiles aim at decreasing or at least minimizing the induction of higher order aberrations. These higher order aberrations are the cause of decrease in quality of vision, including subjective visual symptoms of glare, haloes and reduced contrast sensitivity. Expansion of various corneal imaging modalities has helped a LASIK surgeon to provide a customized ablation profile with desirable outcomes. Topo-guided ablation profile is considered to induce lesser higher order aberrations along with causing a lesser tissue ablation providing a higher safety margin (in most of the studies). This customized profile can encounter hurdles in treatment of irregular corneas (post refractive surgery decentered corneas or those having a small ablation zone) and also is capable of tackling myopia with high astigmatism with excellent visual outcomes.
