“… 24 The reported dynamic pupil size has got major clinical implications in our studied population, most importantly while choosing pupil-dependent multifocal IOLs. 25 , 26 Furthermore, both pupil size and Z4 are key factors for optimized aspheric IOL implantation. 27 Paucity of studies on our population that determine such parameters validated the aim of our study, especially with the relevant clinical implications that would make benefit from the normative values of such parameters.…”

“…With a single focal point, monofocal IOLs are effective in restoring satisfactory distance vision; however, most patients require spectacle correction for intermediate and near vision, even after surgery [1, 2]. Thus, multifocal IOLs were designed to meet the increasing demand from patients for spectacle independence [3]. For providing far, intermediate and near vision simultaneously, multifocal IOLs possess two or more independent focal points, which result in contrast reduction and increased photic phenomena, thus reducing visual quality [4].…”

Background This study aims to evaluate the efficacy and safety of extended depth of focus (EDOF) intraocular lenes (IOLs) in cataract surgery. Methods All comparative clinical trials that involved bilaterally implanting EDOF IOLs in patients with cataract were retrieved from the literature database. We used random effects models to pool weighted mean differences (WMD) and risk ratio (RR) for continuous and dichotomous variables, respectively. Results Nine studies with a total of 1336 eyes were identified. The subgroup analysis was conducted according to the type of IOLs used in the control group. Compared with monofocal IOLs, EDOF IOLs produced better uncorrected intermediate visual acuity (WMD: -0.17, 95% CI: − 0.26 to − 0.08, P = 0.0001) and uncorrected near visual acuity (WMD: -0.17, 95% CI: − 0.21 to − 0.12, P < 0.00001). EDOF IOLs resulted in reduced contrast sensitivity, more frequent halos, however, higher spectacle independence (RR: 2.81, 95% CI: 1.06 to 7.46, P = 0.04) than monofocal IOLs. Compared with trifocal IOLs, EDOF IOLs produced worse near visual acuity (MD: 0.10, 95% CI: 0.07 to 0.13, P < 0.0001). EDOF IOLs performed better than trifocal IOls in contrast sensitivity, and there were no significant difference in halos and spectacle independence. Serious postoperative complications were rare, with no adverse events were reported in most studies. Conclusions Increasing the risk of contrast reduction and more frequent halos, EDOF IOLs provided better intermediate and near VAs than monofocal IOLs. At the expense of near vision, patients receiving EDOF IOLs have better contrast sensitivity than those receiving trifocal IOLs. Halo incidence and spectacle independence of EDOF IOLs were similar to those of trifocal IOLs.

“…Studies have shown that MIOLs are comparable to monofocal IOLs for distance vision but are more effective for near vision and provide greater spectacle independence. 2–4 Based on the focality, MIOLs are classified as either bifocal (2 foci) or trifocal (3 foci). 5…”

“…Although MIOLs are more frequently associated with photic disturbances than monofocal IOLs, the trifocals IOLs have improved performance in photic phenomena than bifocal IOLs. 4,6,7 More recently, extended depth of focus (EDOF) IOLs, a new class of IOLs have been introduced. The EDOF IOLs elongate a single focal point over a range of distance using diffractive optics, thus providing better intermediate performance than monofocal IOLs.…”

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.
