A simplified fitting philosophy
Our new fitting process is based on eye care professionals’ real-world experiences.
- Fitting lower ADD powers are now simpler than ever, by using the same D lens design for both eyes
- Fitting higher ADD powers continues to be flexible, giving you more options for exceptional vision performance
Initial visit
Step 1 Start with new refraction and verification of eye dominance
(fogging technique).
Step 2 Select the distance prescription based on spherical equivalent
corrected for the vertex distance. Choose D or N lens design based on needed
ADD power:
| ADD | Dominant eye | Non-Dominant eye |
|---|---|---|
| +1.00 | D | D |
| +1.50 | D | D |
| +2.00 | D | D |
| +2.50 | D | D |
Visual acuity expectations when using the D and N lens combination
| Lens | Distance | Near |
|---|---|---|
| Binocularly | 20/20 | 20/20 |
| D Lens | 20/20 | 20/40 better |
| N Lens | 20/40 better | 20/20 |
Step 3 Although the lens will equilibrate quickly, allow patients to
adapt to lenses for a minimum of 15 minutes before assessing vision. If
binocular vision is unacceptable, perform a monocular over-refraction, using
hand-held trial lenses, to determine which eye needs improvement.
To improve distance vision add +/-0.25D (up to +/-0.50D) to the eye that needs
improvement.
To improve near vision add +/-0.25D (up to +/-0.50D) to the eye that needs
improvement.
Clinical Tips Prescribe maximum plus power for distance vision (Do not
over minus)
Choose the lower ADD power when possible; not necessary to overprescribe the
ADD power
Test patient’s near function vision with their cell phone

A unique multifocal lens for unique eyes
Balanced Progressive” Technology
- Optimized for exceptional vision at all distances: near, intermediate, and far
- Allows for personalized fitting for each wearer and each eye
- The streamlined fitting process helps ensure success for presbyopic patients
Follow-up visits one week later
If the patient requires further enhancement to distance or near visual acuity.
Step 1 Evaluate binocular visual acuity.
Step 2 Check monocular visual acuity.
Step 3 Perform over-refraction using hand-held trial lenses (avoid using
a phoropter).
FIRST OPTION: To improve either distance or near vision, modify distance
vision by +/- 0.25D in the eye that needs improvement.
SECOND OPTION: To improve near vision add +0.50D to the ADD power of the
eye that needs improvement.
