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.

“…11,15,16,[18][19][20][21] This technology is called Enlighten ® Optical Technology by the manufacturer (Alcon Laboratories, Inc.) and there has been a great acceptance and patient satisfaction with this intraocular lens as the intermediate vision is very comfortable and sharp. 11,15,16,[19][20][21][22][23][24][25][26][27][28][29][30] The diffractive zone is also in the central portion and occupies 4.5 mm of the optical zone. It adds a negative spherical aberration of −0.1 μm on the anterior face of the lens to compensate the positive spherical aberration generated by the average human cornea.…”

The aim of this study was to compare the visual outcomes and subjective visual quality between bilateral implantation of an extended depth of focus intraocular lens, J&J Vision Tecnis Symfony ® ZXR00 (Group A) and bilateral implantation of a diffractive trifocal intraocular lens, Alcon Acrysof IQ PanOptix ® TNFT00 (Group B). Methods: This prospective, nonrandomized, comparative study of consecutive cases assessed 52 eyes of 26 patients operated on by the same surgeon (WTH) and binocularly implanted with multifocal intraocular lenses between May 2016 and July 2018. Binocular visual acuity for far, intermediate and near was tested in all cases. Ophthalmological evaluation included the measurement of binocular uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), uncorrected near visual acuity (UNVA) at 40 cm, uncorrected intermediate visual acuity (UIVA) at 70 cm, monocular visual defocus curve and the quality of life (QoL) questionnaire, National Eye Institute Visual Functioning Questionnaire-25 (NEI-VFQ 25). Results: Postoperative UDVA was 0.00 and 0.09 logMAR (P<0.001), UIVA was 0.20 and 0.39 logMAR (P<0.001) and UNVA was 0.16 and −0.01 logMAR (P<0.001) in groups A and B, respectively; postoperative CDVA was −0.05 and 0.06 logMAR (P<0.001) in groups A and B, respectively. Conclusion: Both groups reported good subjective quality of vision regarding long, intermediate and short distances. Group A had a better performance for binocular UDVA, UIVA at 70 cm and CDVA, while regarding the monocular defocus curve, Group A outperformed Group B for long distances. Furthermore, Group B surpassed it in the short to very short distances, between the range of ≥2.00 D to 5.00 D of vergence. While Group A had a better performance regarding the vergences between 0.00 and 1.00 D (P<0.05) and at the vergence of +2.50 D (P=0.007). Group B outran Group A for UNVA at 40 cm.

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.

Abstract: All the tested IOLs provided good visual outcome, reading performance, and spectacle independence after cataract surgery. While trifocal IOLs gave better near visual acuity results, the ERV IOL provided better contrast sensitivity.
