Summary

To compare the efficacy to different profiles, direct head-to-head studies had been conducted. In one previous review study revealed that TG LASIK provided patient with better uncorrected visual acuity (UCVA) than WFO LASIK and WFG LASIK. In recent previous contralateral eye studies also showed that TG LASIK induced less postoperative higher-order aberration than WFO LASIK. However, these studies included only low-to-moderate myopia patients, for patients with high myopia (spherical equivalent \> 6D), the effect of TG LASIK comparing with WFO LASIK had not been reported before.

The aim of our study is to analyze and compare the visual performance of TG LASIK and WFO LASIK in high myopia and low-to-moderate myopia patients, , particularly UCVA, corrected distance visual acuity (CDVA), contrast sensitivity (CS), and wavefront aberration.
