  1. *The magnitudes of anterior and posterior corneal surfaces were fitted as sixth-order Zernike polynomials.
  2. [a]Measured by Pentacam (Oculus Optikgeräte GmbH).
  3. [b]Measured by Lenstar LS900 (Haag-Streit).
  4. [c]Estimated based on Eqs. (3–5)39,41,45.
  5. [d]Estimated based on the Navarro eye model34.
  6. [e]Set values for Zemax simulation.
