“…24 Previously, Marques and Ferreira 25 found no significant differences in contrast sensitivity between eyes implanted with the AT LISA tri IOL (Carl Zeiss Meditec AG) and a FineVision trifocal IOL, with the contrast sensitivity within the normal range, a finding that was confirmed by others. 6 This trend toward reduced contrast sensitivity results with toric trifocal IOLs in comparison to nontoric trifocal IOLs can be seen in clinical outcomes using an IOL with a very similar optic design (AT LISA tri and AT LISA tri toric). As with the investigated Physiol trifocal IOLs, the published literature by the authors on the Carl Zeiss Meditec AT LISA IOLs demonstrated a similar difference in contrast sensitivity between toric and nontoric IOL models.…”

“…4,5 However, halos, glare, and reduced contrast sensitivity continue to be reported with presbyopia-correcting IOLs. 6,7 Multifocal IOLs can be broadly categorized based on their design: either concentric focal zones (alternating for near, intermediate, or far) or segmented, two zones (bifocal) with one zone for distance and the other for near. One known issue with these designs is a reduced visual acuity at intermediate distances.…”

“…1 To address patient expectations and demand for presbyopia correction, several presbyopia-correcting IOLs based on different optical approaches are in use, which broadly include multifocal, accommodative and the extended depth of focus (EDOF) IOLs. [2][3][4][5] Among these, EDOF IOLs have been available for only the past few years; best practices for obtaining optimal outcomes are still evolving.…”

“…Unlike multifocal IOLs that split the light into distinct focal point(s), the elongated focal zone of EDOF IOL reduces overlap of near and far images, thus generating a lower incidence of halos and glare. 5 Additionally, the use of achromatic technology to correct longitudinal chromatic aberrations improves the visual performance of the EDOF IOL. 6 EDOF IOLs have been shown to yield excellent distance and intermediate visual acuity.…”

Purpose: To determine the refractive target of extended depth of focus (EDOF) intraocular lenses in dominant and non-dominant eyes which provides the best binocular vision at all ranges after cataract surgery. Patients and Methods: This retrospective, single-center, non-comparative study included 47 patients who had undergone bilateral cataract surgery with implantation of EDOF IOLs (Tecnis Symfony or Tecnis Symfony Toric) targeting emmetropia in both eyes. Binocular uncorrected visual acuity at distance (UDVA), near (UNVA), intermediate (UIVA), and manifest refraction spherical equivalent (MRSE) were recorded between 1 and 3 months after the second-eye cataract surgery. Scattergrams for combined binocular UDVA, UIVA, UNVA and postoperative MRSE were plotted and the points of minima of the quadratic regression curve for the dominant and non-dominant eyes were considered as the optimum MRSE corresponding to the best overall visual acuity. Subgroup analysis of patients who achieved UDVA and UIVA ≥20/20 and UNVA ≥20/30 was also performed. Results: For the overall group, the optimum MRSE was −0.08 D for dominant and −0.63 D for non-dominant eyes. In a subset of 17 patients who achieved excellent acuity at all distances, the mean MRSE for the dominant and non-dominant eyes was −0.07 ± 0.14 D and −0.21 ± 0.24 D, respectively. Conclusion: Excellent visual acuity at all ranges can be achieved with bilateral EDOF intraocular lenses implanted after cataract surgery. Our results indicate the best results when the dominant eye is targeted at emmetropia and the nondominant eye is targeted between −0.21D and −0.63D, with excellent results shown with mild myopia of −0.21 in the non-dominant eyes. Future studies with larger sample sizes and subjective patient-reported outcomes may validate current study outcomes.

“…Different studies have shown the clinical performance of EDOF IOLs, reporting good visual and contrast sensitivity outcomes, with high levels of patient satisfaction [9]- [14]. Concerning photic phenomena outcomes, whereas some comparative trials have found no significant differences between multifocal and EDOF IOLs [9] [11] [12], others have found a lower incidence of photic phenomena with EDOF designs compared to trifocal IOLs [13]. The aim of the current study was to evaluate the clinical outcomes of a new model of diffractive EDOF IOL in terms of visual acuity across different distances, contrast sensitivity, photic phenomena and patient satisfaction.…”

Purpose: To evaluate the early clinical outcomes of a new diffractive extended depth-of-focus (EDOF) intraocular lens (IOL). Methods: Prospective case series enrolling patients undergoing cataract surgery with implantation of the EDOF IOL AT LARA (Carl Zeiss Meditec, Jena, Germany). Distance, intermediate and near visual acuity were evaluated during a follow-up of 1 month. Likewise, defocus curve, binocular mesopic contrast sensitivity, perception of photic phenomena, patient satisfaction and spectacle independence were assessed. Results: The study enrolled 38 eyes of 19 patients with a mean age of 69.5 years. A significant reduction of manifest refraction and improvement in corrected distance visual acuity (CDVA) was observed with surgery (p < 0.001). All eyes achieved a 1-month postoperative binocular CDVA of 20/20 or better. Likewise, all eyes achieved a DCIVA of 20/30 or better at 1 month postoperatively, and a total of 92.1% achieved DCNVA of 20/40 or better. Concerning refractive predictability, 97.4% of eyes had a 1-month postoperative spherical equivalent within ±0.50 D. The level of patient satisfaction with distance, intermediate and near vision was high, with 95% of patients reporting that they would have the same surgical procedure with the same IOL again. Difficulties in night driving or associated to halos were low. A total of 89% of patients reported to be spectacle independent postoperatively. Conclusions: The EDOF IOL AT LARA is able to provide a functional restoration of the visual function across distances after cataract surgery, with very high levels of patient satisfaction and minimal incidence of photic phenomena.
