Fitting Recommendations
- Starting point: Flat K – 1/3(flat K – steep 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.
