AstiCon

Description

Description

The AstiCon lens has a spherical back optic zone radius (BOZR) with a toric periphery (second curve) edge design.

The AstiCon should be used on Toric Corneas with

  • Corneal Astigmatism between -2.50D and -3.50D.
  • Corneal Eccentricity (e-value) under 1.00.

Fitting Recommendations

  • Starting point: 0.1 to 0.15 steeper than K.
  • The more astigmatism, the steeper the base curve starting point should be.
  • If the lens should be made steeper, compensate by going flatter in the peripheral curves to avoid tight fits.
  • If there is still cyl coming through, a BackToric lens will be a better option.
