Corneal Asphericity and Higher-Order Aberrations after FS-LASIK and Trans-PRK for Myopia

Figure 1

Comparison of the Q value changes in the FS-LASIK and Trans-PRK groups. The Q value of the anterior corneal surface significantly shifted to a positive value after the FS-LASIK and Trans-PRK groups. No significant difference between FS-LASIK and Trans-PRK in the changes of the Q value of the anterior corneal surface was found.
