Technical data

  • Total diameter: 12.00 -> 15.00… 19.00 mm (according to material)
  • Base curve: 7.00 -> 12.00 mm
  • Sphere: -40.00 -> + 40.00 dpt
  • Flattening: (-) flowing/ (+) pronounced/ (–) monocurve

steps 0.01 mm / 0.01 dpt / 1°

First fitting

  • Total diameter: = corneal diameter + 2.10 mm
  • Base curve: = flattest corneal curve + 0.60 mm
  • Sphere: glasses in DVO = 0 mm
  • Flattening: comparing the sulcus
