From: Influence of angle alpha on visual quality after implantation of extended depth of focus intraocular lenses

Parameter R2 P Equation
3 mm pupil diameter
 SA in internal aberration 0.087 0.008 Y = 0.147 * X – 0.131
5 mm pupil diameter
 HOA in ocular aberration 0.079 0.012 Y = 0.607 * X + 0.427
 HOA in internal aberration 0.072 0.017 Y = 0.533 * X + 0.364
  1. SA Spherical aberration, HOAs Higher-order aberrations
