The given review is to primarily address the influence of high order aberrations in refractive surgery outcomes regarding objective and subjective types of measurement. Additionally, there is going to be reference to how Wavefront-Optimized (WFO) ablations and Wavefront-guided ablations (WFG) affect both the final refractive result and the quality of vision. Standard Lasik is known to induce high-order aberrations, resulting in reduced visual performance, diminished subjective visual functioning as well as decreased quality of life related to vision. Therefore, Wavefront-optimised (WFO) ablations and Wavefront- guided ablations (WFG) have been recruited to deal with this problem. On the other hand, smile (small-incision lenticule extraction) as another introduced refractive surgery method constitutes an alternative suggestion. This literature review highlights recent developments in this field. Thus, considering the above parameters there are going to be suggestions regarding the selection of the optimum procedure.
