Optimizing outcomes with multifocal intraocular lenses

AcrySof IQ PanOptix Model TFNT00 (Alcon Laboratories, Fort Worth, TX) is a 1-piece aspheric hydrophobic presbyopia-correcting intraocular lens (IOL) launched in 2015. Unlike traditional trifocal IOLs that usually have an intermediate focal point of 80 cm, the PanOptix IOL is designed to have an intermediate focal point of 60 cm (arms-length), a more natural and comfortable working distance to perform functional tasks on computers, laptops, mobiles, among others. The non-apodized PanOptix IOL uses the ENhanced LIGHT ENergy (ENLIGHTEN; Alcon Laboratories, Fort Worth, TX) optical technology that provides high (88%) utilization of light energy, low dependence on pupil size in all lighting conditions, and a more comfortable near-to-intermediate range of vision than traditional trifocal IOLs. This review provides an overview of the clinical performance of the PanOptix IOL and discusses it in the context of other commercially available trifocal IOLs, FineVision Micro F (PhysIOL, Liege, Belgium), the AT LISA tri 839MP (Carl Zeiss Meditec AG, Jena, Germany) and the extended depth of focus IOL, TECNIS Symfony (Abbott Medical Optics, Santa Ana, CA). A literature search was performed in the PubMed database to identify studies that have assessed the visual and other clinical outcomes with the PanOptix IOL. In total, 12 studies were included in this review article. Overall, the clinical evidence suggests that in general good visual outcomes, along with a high degree of spectacle independence, are achieved in patients implanted with the PanOptix, FineVision, AT LISA and Symfony IOLs. However, every MIOL has its benefits and limitations, which along with patient's needs and clinical conditions are important factors to consider while selecting an IOL to achieve best possible post-operative outcomes.

“…Presbyopia-correcting IOLs can be largely categorized depending on the optical principle and the number of foci generated [1][2][3]. Most IOLs use a diffractive-refractive optic, while others utilize different optical designs to provide multifocality [4,5].…”

Laboratory evaluation of the optical properties of two extended-depth-of-focus intraocular lenses

Background: To experimentally compare the optical performance of two different Extended-Depth-of-Focus (EDOF) intraocular lenses (IOLs) using a standardized optical bench setup. Methods: In this experimental study, following IOLs were assessed: the TECNIS® Symfony ZXR00 (Johnson&Johnson, Santa Ana, USA) and the AT LARA 829MP (Carl Zeiss Meditec, Jena, Germany) IOLs. The through-focus modulation transfer function (MTF) values were measured at a spatial frequency of 50 lp/mm and at aperture sizes of 2, 3, and 4.5 mm. Each IOL was measured while centered using ISO 11979-2 Model 1 (aberration-free) and Model 2 (+ 0.28 μm spherical aberration) corneas. United States Air Force (USAF) target images were also recorded for a qualitative evaluation. Results: At 2 mm pupil with ISO1 cornea, the primary and secondary foci of both IOLs appeared to merge, providing an elongated depth of focus. At 3 and 4.5 mm pupil sizes, the through-focus MTF curves of both IOLs showed a bifocal-like V-pattern. While the Symfony IOL showed an overall superior MTF values when measured with the ISO2 cornea, the opposite propensity could be observed with the AT LARA IOL. This optical behavior could be qualitatively confirmed by the USAF target images. Conclusions: Although the two EDOF IOLs share similarities in their optical properties, the main difference lies in their optical design and performance with respect to spherical aberration. Such characteristics should be taken into account during IOL and patient selection.

Presbyopia results from loss or insufficiency of the eye's accommodative ability, and clinically manifests as the inability to focus near objects on the retina. It is one of the most common causes of visual impairment worldwide especially in adults of productive or working age. Various means of compensating for the loss of accommodative ability have been devised from optical tools such as spectacles and contact lenses, to topical medications and to surgical procedures. A comprehensive search on journal articles about topical and surgical correction of presbyopia was undertaken. The various techniques for presbyopia correction, as enumerated in these articles, are discussed in this paper with the addition of our personal experience and perspective on the future of these techniques.
