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.

“…multifocal IOLs [1,2]. The extended depth-of-focus (EDOF) IOL was recently developed based on the elongated focus, thereby minimizing the dysphotopsia phenomena induced by multifocality and to provide better optical quality on the whole addition range [2,3].

However, the EDOF IOL resulted in worse outcomes for near vision compared to those for far and intermediate vision [2,[4][5][6]. A recently published study demonstrated that the eyes with implantation of EDOF IOL aimed for − 0.75 D myopia provided better uncorrected near vision and similar uncorrected intermediate vision compared with the emmetropia eyes and maintained excellent distance vision outcomes at the same time [7].…”

BackgroundTo compare the visual performance and astigmatism tolerance of 3 intraocular lens (IOLs): monofocal, bifocal, and extended depth-of-focus (EDOF) IOLs targeting slight myopia.MethodsOverall, there were 60 cataract surgery eyes from 60 patients with implantation of a monofocal, bifocal or EDOF IOL (20 eyes in each IOL group). The EDOF IOLs targeted slight myopia (-0.25 D to -0.75 D). Intragroup comparison of visual acuity, defocus curve, objective optical quality, contrast sensitivity, Visual function questionnaire scores, patients’ overall satisfaction, and the astigmatism tolerance were performed 3 months after surgery.ResultsThe EDOF group provided equivalently excellent distance visual outcomes (0.06±0.12) as the monofocal (0.06±0.09) and bifocal (0.03±0.09) groups (P=0.554), better intermediate vision than the other 2 groups (P<0.05), and similarly satisfactory near visual outcomes (0.23±0.16 at 20 cm, and 0.17±0.14 at 33 cm) as the bifocal group (0.28±0.14 at 20 cm, and 0.08±0.10 at 33 cm) (P>0.05). The contrast sensitivity of EDOF IOL was slightly decreased compared to that of monofocal IOL, but it was better than that of bifocal IOL. The EDOF group showed significantly higher satisfaction than the bifocal group did when preoperative corneal astigmatism was 0.75 D or greater (P=0.009). A significant negative correlation between the corneal astigmatism and patient satisfaction was observed in only the bifocal group. ConclusionsThe EDOF IOLs targeting slight myopia offered satisfactory visual outcomes at an extended range from far to near distances. The EDOF and monofocal IOLs showed a better tolerance to astigmatism than did the bifocal IOL.

Comparative analysis of visual outcomes with 4 intraocular lenses: Monofocal, multifocal, and extended range of vision

Abstract: The extended-range-of-vision IOL and +2.5 D multifocal IOL provided significantly better intermediate visual restoration after cataract surgery than the monofocal IOL and +3.0 D multifocal IOL, with significantly better quality of vision with the extended-range-of-vision IOL.
