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.
Can I fit Duette on keratoconus and other irregular corneas?
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.
What is the difference between Duette Progressive and Duette Multifocal?
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.
How long should I let the lenses settle before assessing the fit?
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.
No, the Duette fit is assessed based on comfort, lens movement and over-refraction.

At this stage, there may be awareness of the, which is acceptable. Differentiate between discomfort and mild awareness. Mild awareness is not a concern as adaptation by wearing the lenses will eliminate this sensation.
Due to the tear lens, the final lens power is expected to be up to 1.00D more minus than the spherical portion of the spectacle refraction – because of tear lens neutralization. (Do not adjust for the cylinder correction of the spectacle Rx.)
What do I do if vision is unacceptable at follow-up?
First, confirm the patient is not over-minused and that there is no residual astigmatism present. Adjust the lens power as necessary.
To troubleshoot multifocal vision complaints:
Do not make any changes until the patient has been wearing the lenses for at least two weeks. Adapting to the optical system of the Duette Multifocal lens is like adapting to progressive glasses. Making changes to the lens parameters before adaptation has taken place greatly increases the likelihood of failure.
