Additionally, the C-2500L also includes a built-in dioptric corrector to focus the viewfinder to the user's eyesight.
McLeod and colleagues proposed a simple formula to approximate the power change occurring with axial anterior shift of an AIOL optic: [DELTA]Dc [approximately equal to] (Dm/ 13) x [DELTA]s (Equation 1) where [DELTA]Dc is the change in the eye's dioptric power, Dm is the power (D) of the AIOL, and As is the change in lens position (mm).
