Multifocal Optical Alignment for Scleral Lenses

Ensure the near zone is on target with a lens that aligns the optics

The Zen Multifocal design aligns the near zone over the visual axis instead of the pupillary axis which has been shown to provide clear vision in soft contact lenses. The multifocal design is available on both Zenlens and Zen RC scleral lenses and comes with all the benefits you have come to expect:

  • SmartCurve technology simplifies your fitting - only modify the parameters you want
  • MicroVault which creates a precisely designed elevation to vault the lens over a peripheral obstruction

Design Parameters

  • Center-near optics in both eyes
  • ADD powers from +1.00D to +3.50D in 0.25D steps
  • Variable center-near zones from 1.5 mm to 3.0mm in 0.5 mm steps
  • Diameters:
    • Zen RC: 14.8mm, 15.4mm
    • Zenlens: 16.0mm, 17.0mm

Visual Axis - Line of Sight

  • The visual center (line of sight) is not centered geometrically within the pupil. Studies show that soft multifocal contact lenses with decentered optics provide clear near vision.
  • ┬áZen Multifocal places the near zone slightly nasal and superior for each eye.
