Three Words: Simplicity, Quality, Performance

SAV-IOL’s Lucidis IOL combines the fantastic far vision and few photopic phenomena of a monofocal lens, with the added bonus of a high-quality extended depth-of-focus.

In some respects, monofocal IOLs are hard to beat. Other than the obvious - a single focal plane - the drawbacks are few, and compared with the current crop of diffractive multifocal IOLs, they provide unparalleled distance vision with a very low rate of visual disturbances. Neuroadaptation is rapid, and patients are almost immediately comfortable with their postoperative vision.

The Swiss IOL company, SAV-IOL, set out to make a lens with all of the advantages of a monofocal IOL, but with the benefit of continuous vision. To that end, they adapted their “Instant Focus” extended depth-of-focus (EDOF) technology to a classic monofocal design to make Lucidis – a hydrophilic single-piece foldable IOL. The optic comprises a 6 mmdiameter refractive part providing distance and a 1 mmdiameter aspheric element in the center of the optic to extend the depth of focus from near towards distant vision (Figure 1a,b). The aspheric element uses a pseudo nondiffracting beam (PNDB); the benefit of this approach being the maintenance of a constant resolution and light intensity on the retina (Figure 1c).
