Why would I need two lenses in one eye when a single lens might do ?
Of course there are premium , primary lenses available which can treat your cataract while providing additional features. However, these lenses sometimes fail to meet a patient's expectations, and in these cases, it is very difficult to remove and replace the lens. Even when the most accurate preoperative assessments are performed, further adjustment of the lens power may become necessary at a later stage.
The supplementary lenses used in the DUET technique can be removed and exchanged with relative ease, making it more straightforward to correct the lens power or to undo the procedure completely if required. The DUET technique also makes retrospective vision refinements and enhancements possible for patients who have already undergone a cataract treatment.
I have already had a cataract operation - can I still opt for a DUET treatment?
Yes, the supplementary lens can be implanted at eany time after your initial cataract surgery. In some cases, it may even be necessary.
On occasions, a primary lens may not give you the lens power you require to see well. In such situations, a supplementary lens may be implanted to add or reduce the power of the first lens and give you the result you hoped for.
I am due to receive a corneal graft - does that rule me out of a DUET treatment?
DUET is ideal for situations where refractive powers change over time, like they do after a cornea has been transplanted. However, if you have undergone a history of surgical interventions in your eye, very careful clinical assessment will be required.
How do I know if I am suitable for the DUET procedure
The vast majority of patients who have no contraindications against cataract surgery will also be suitable for a DUET procedure. Nonetheless, you must discuss your suitability in depth with your surgeon.
How much does the DUET technique cost?
The cost of cataract surgery is usually covered by statutory health insurance when a standard lens is implanted. As with any other premium lens, additional costs may be incurred by opting for a DUET procedure.
How does DUET compare with laser treatments?
Laser vision correction is not suitable for all as it can only be performed in patients who meet specific corneal thickness and curvature requirements. In addition, laser correction is associated with a notable risk of dry eye after the procedure, offers a limited range of correction, and above all, is not reversible.
DUET is different. The use of an implant ensures that the procedure is reversible and therefore less risky. It's efficacy is not dependent on corneal thickness and it will not cause dry eyes. As the lens is made to order to fit your individual requirements, if offers a wider range of treatment options compared with laser correction.
