  1. RE right eye, IOL intraocular lens, s. spherical, c. cylindrical, A axis
  2. aVisual acuity: best-corrected visual acuity at the final visit in patients with observation while best-corrected visual acuity just before the surgery in patients with lensectomy. Refractive error, determined basically by autorefraction and also by trial-lens exchange in elder patients
  3. bVisual acuity: best-corrected visual acuity at the final visit
