Consejos de adaptación

  • Diámetro total: diámetro de la córnea – 2,00 mm
  • Curva base:
    • ASP: r0 – Kflat (rcfl)
    • Sms:
      • ( rcfl – rcst) a 0,30 mm – > BC – rcfl – 0,05
      • (rcfl – rcst) a 0,40 mm – > rO a rcfl – 0,10
      • (rcfl – rcst) a 0,50 mm – > rO a rcfl – 0,15
  • Aplanamiento: ASP & SMS: excentricidad (En) – excentricidad de la córnea a 30o redondeado al siguiente 1/10

Elección de la zona de lectura

Determinar si la visión es alterna (cambio de zonas ópticas por traducción) o simultánea (cambio de zonas ópticas por selección de corteza visual):

  • Visión alternativa: zona de lectura en la periferia (la mayoría de los casos)
  • Visión simultánea: zona de lectura en el centro
RequirementsBifocal BfSimple progressive Sp
Myopia Addition < 1.75 dpt
Myopia: Addition ≥ 1.75 dpt
Priority in distance vision
Priority in near visiondominant eyenon dominant eye
Good contrast
  • La visión a distancia depende de centrar, cerca de la visión en el movimiento (traducción).
  • Para una buena traducción, se necesita un movimiento de 1 a 2 mm. Se ve afectada por rO y T.
  • La fluoroscopia debe mostrar una buena alineación de la zona óptica.
