Fitting as usual ... superior results
You’ll find it’s as simple to fit Gradal® Individual and Gradal® Short i as it is other progressive lenses. Just follow a few easy steps:
- Anatomically fit the frame to the patient’s face, as usual Determine the monocular distance PD’s and fitting heights, as usual
- Specify the frame manufacturer, model and type, as usual
- Specify the frame A, B, DBL and ED measurements, as usual.
- Specify the lens type:
- Gradal® Individual for fitting heights of 18 mm and above
- Gradal® Short i for fitting heights from 15 mm to 18 mm
- Submit the order, as usual
Already, using just these values, as usual, Gradal® Individual and Gradal® Short i dramatically outperform any other traditional PAL on the market, thanks to Rx and PD optimized front surface design.
But there’s even more you can do to make sure your patient gets the most perfect vision possible.
The extra mile ... even better
Unless otherwise specified, standard values are used in the lens design for the back vertex distance (BVD) and the pantoscopic angle (PA).
However, since no two patients are identical, many of your patients’ measurements will fall outside the acceptable range for these standard parameters. In order to give each patient truly optimal performance, Gradal® Individual lenses allow you to incorporate each person’s unique measurements into his or her lens design.
It’s easy to use the ZEISS Gradal® Individual Fitting Tool to verify the BVD and PA and, if applicable, to determine measurements that are beyond the acceptable range. Specify the BVD and PA whenever you have a patient with values beyond the acceptable range for these parameters:
 | Back Vertex Distance (BVD) | Pantoscopic Angle (PA) |
| Standard value | 14.0 mm | 9° |
| Acceptable range | 12.0 to 16.0 mm | 7° to 11° |
Even more options ... premium performance
Gradal® Individual lenses are so advanced and flexible that Carl Zeiss can offer even more customization capabilities for your patients:
- Zero mm inset for monocular patients
- specification of individual near working distances
