The main reasons for patient dissatisfaction following a multifocal intraocular lens implantation are residual ametropia, posterior capsule opacification (PCO), dry eye, IOL decentration, inadequate pupil size, and wavefront abnormalities.[1,6]

In our study, cyclopentolate was used to dilate 2 eyes with the diffractive IOL and a small pupil; the treatment improved the patients’ symptoms. In contrast, 2 eyes with the zonal refractive IOL were treated effectively with brimonidine tartrate 0.2% to decrease glare symptoms.

The monocular photopic defocus curve (gray) of a patient with a 3-mm pupil and a monofocal IOL. Note the broader monocular defocus curve (blue) in a patient who received an IC-8 IOL with a 1.36-mm aperture targeted for emmetropia.

Jul 7, 2022 · In this video, we explore the ways that pupil size affects the EDOF IOL outcomes, particularly with the Alcon Vivity lens implant (both the Alcon AcrySof Vivity and now the newer Alcon Clareon Vivity, in toric and non-toric varieties).

Oct 20, 2023 · The Symfony EDOF IOL has diffractive rings throughout the optic and can achieve a wide depth of focus range independent of pupil size. It also allows more consistent refractive targeting.

IOLs (intraocular lenses) are clear, artificial lenses that replace your eye’s natural ones. You receive IOLs during cataract surgery and refractive lens exchange. IOL implants correct a range of vision issues, including nearsightedness and age-related farsightedness. They may also help reduce your reliance on glasses for certain types of tasks.

Feb 1, 2011 · Studies suggest that multifocal IOLs experience degraded performance at somewhere between 0.3 and 0.7 mm of decentration relative to the pupil. A single anterior capsule rent has the potential of creating a “pea-pod” contracture that pushes the IOL off-center.

Sep 15, 2008 · The authors found that patients implanted with diffractive, pupil-independent multifocal IOLs obtained better near vision, experienced less unwanted photic phenomena, and were less reliant on glasses than those who received monofocal or refractive multifocal IOLs.

Nov 1, 2020 · Eyes implanted with multifocal IOLs had a photopic pupil size of 3.5 mm or less and mesopic pupil size of 5 mm or less. Mesopic and photopic pupil size decreased 0.28 and 0.15 mm per decade, respectively.

The Clareon® PanOptix® IOL is the first available trifocal lens in the US. Learn the features and see how it may assist patients with vision correction.
