Duette HD is ideal for any patient who wants to see their best. Reach for Duette HD for patients who are unhappy with their vision in soft lenses, frustrated with fluctuating vision or are ready to see better at night. Duette HD is also an excellent lens for GP wearers who love the vision GP lenses deliver but would like the wearability of a soft lens.
Duette Progressive is an ideal lens for any presbyope wanting the best possible vision in contact lens. The intuitive fitting method, ability to order empirically and competitive price-point make Duette Progressive a go-to lens for your presbyopic patients.
No, Duette lenses are designed for your normal cornea patients and are not approved for patients with any type of corneal irregularity. Reach for the SynergEyes UltraHealth lens for your keratoconus and irregular cornea patients.
Duette Progressive is the newest Duette lens for presbyopes and has a single zone size (3mm) with a choice of three add powers: +1.00,+1.75 and +2.50. Duette Multifocal has two zone size options (small and large) with all available add powers built into the add zone. Both lenses are built on the Duette hybrid platform.
The empirical fitting calculator selects the GP base curve that is most closely aligned with the flattest K and the Flat skirt curve.
When fitting Duette Multifocal the calculator selects the small zone for the right eye (or dominant eye if specified) and the large zone for the other eye.
The calculator typically selects the appropriate base curve and skirt curve. In some cases, a slight tweak to the lens power may be needed.
Duette lenses are inserted like soft lenses. There is no need to put solution in the bowl of the lens or use any special tools or techniques to get the lenses on the patient’s eyes.
Allow the lenses to settle for at least ten minutes and up to 30 minutes before assessing the fit. The timing should fit with your practice workflow. Many practitioners send their Duette patients out to the waiting room while the lenses settle to allow the patient to experience the exceptional vision that Duette lenses deliver.
Duette lenses should move approximately 1mm on blink. If adequate movement is not observed, a Flat2 skirt should be ordered.
No, the Duette fit is assessed based on comfort, lens movement and over-refraction.
*In some patients the tear chemistry may react with the peroxide to cause a permanent white ring at the junction of the rigid center and soft skirt. This ring does not affect vision or comfort.

Your patient should be able to comfortably wear her Duette lenses for 8 to 14 hours each day. If that is not the case:
First, confirm the patient is not over-minused and that there is no residual astigmatism present. Adjust the lens power as necessary.
