Technical data

  • Total diameter: 7.50 -> 12.00 mm
  • Base curve: 5.70 -> 12.00 mm
  • Sphere: -40.00 -> + 40.00 dpt
  • Addition: +0.50 -> +4.00 dpt
  • Central optical zone Zoc: 1.00 -> 4.50 mm

steps 0.01 mm / 0.01 dpt / 1°

First fitting

  • Diameter and base curve: We suggest to use our trial set (Orbiflex S3S/ FlexCone/ FlexMed)
    • Choose ØT
    • Choose the number of flattening zones (1 to 4)
    • rO (topography)
  • Power F’v
  • Flattening: Øa0, r1… rn and Ø1… Øn customisable according to topography
  • Advice: Use the on-line tool: “Back surface design” to evaluate axial and radial edge lift
