Comparison of conventional keratometry and total keratometry in untreated myopic eyes and eyes after keratorefractive lenticule extraction

This study demonstrates that TK-values provide a more comprehensive assessment of corneal power, especially after KLEx, where changes in the posterior corneal surface become increasingly significant. The correlations suggest that patients with higher degrees of preexistent myopia or significant amount of laser ablation require special consideration in their refractive corneal assessments.
