Follow these best practices for NaturalVue® (etafilcon A) Multifocal 1 Day Contact Lenses when fitting patients.

See Naturally®

Then enter that full spectacle refraction

into the NaturalVue®

Multifocal QuickStart Calculator1

Refract to 20/15

Use the Red/Green (Duochrome) test for a binocular check that the patient is not overplussed

(one click into the Green for best starting point)

Use the best corrected spectacle

refraction (BCSR) using the full

cylinder component

3 Simple Steps to SuccessIDEAL PATIENT CRITERIA FOR PRESBYOPES: Symptomatic presbyopes, current contact lens wearers or those motivated to wear contact lenses, normal cornea, astigmatism ≤1.00D

1 Starting Power

2 Settle for 10 minutesLet lenses settle 10 minutes & distance vision will begin to clear

3 Evaluate & Enhance - Distance First; then NearDo NOT over-refract with the phoropter, flippers, loose trial lenses or trial frames. Make ON-EYE Diagnostic Lens Changes, if necessary. You are likely only 0.25D away from SUCCESS:

• To enhance DISTANCE: CHANGE THE DIAGNOSTIC LENS POWER on DOMINANT eye only by -0.25D (up to -0.50D) – one lens change at a time and then in the NON-DOMINANT eye by -0.25D only if needed.

• To enhance NEAR: CHANGE THE DIAGNOSTIC LENS POWER on NON-DOMINANT eye by +0.25D (up to +0.50D) – one lens change at a time and then in the DOMINANT eye by +0.25D only if needed.

• For presbyopes, a 0.25D lens change can greatly impact vision. Listen to the patient. If the patient says vision is not clear, change the on-eye lens power. Make a 0.25D change in the power, one eye at a time, starting with -0.25D on the dominant eye to refine distance. To refine near, once distance is optimized, start with +0.25D change on the non-dominant eye.

• Patients in monovision or center near multifocal designs may not have been using their central vision in both eyes for distance. It may take them a few days to fully adapt to this change. (Please see Stepwise Approach)

✓ Verify best corrected spectacle refraction used ✓ Use Red/Green (Duochrome) test to verify Rx is not overplussed✓ Use the NaturalVue® Multifocal QuickStart Calculator✓ Check that lenses have settled 10 minutes

For any questions or issues regarding fitting:

Issue Change the on-eye lens, one eye at a time

Distance vision not clearDominant: Change diagnostic lens -0.25 (-0.50 if needed)Non-Dominant: Change diagnostic lens -0.25 only if needed

Near vision not clearNon-Dominant: Change diagnostic lens +0.25 (+0.50 if needed)Dominant: +0.25 only if needed

Glare, Halos, vision seems “different”Dominant: Change diagnostic lens -0.25 (-0.50 if needed)If Center Near MF wearer or monovision, advise may take 2-3 days to adapt

Issues with driving at night Dominant: Change diagnostic lens -0.25 (-0.50 if needed)

Vision is clear but feels strange, 3D effect, things jumping out at them

Dominant: Change diagnostic lens -0.25 (-0.50 if needed)If Center Near MF wearer or monovision, advise may take 2-3 days to adapt

Have been adding minus and distance still not clear

Recheck that Best Corrected Spectacle Refraction is used. Duochrome is one click into green and NaturalVue® QuickStart Calculator is used

Vision fluctuating, going in and out, feels like have to stare at something to focus; Signs of over-minus

Non-Dominant: Change diagnostic lens +0.25 (+0.50 if needed)Dominant: +0.25 only if needed
