  • •At least 40 years of age and no more than 70 years of age.
  • •≤ 4.00 D of corneal astigmatism.
  • •≤ 2.50 D of refractive astigmatism.
  • •Refractive error range +4.00 DS to -6.00 DS
  • •Require a reading addition (bifocal) of at least 0.75 D
  • •Flat and steep keratometry readings within 40 to 48 D.
  • •Clear, healthy corneas with no irregular astigmatism.
  • •Normal, healthy conjunctiva in both eyes.
