| Sumario: | Mitchell A Jackson,1 Anna M Edmiston,1 Raman Bedi2 1Jacksoneye, Lake Villa, IL, USA; 2IrisARC, Chandigarh, IndiaCorrespondence: Mitchell A JacksonJacksoneye, 300 N Milwaukee Avenue Suite L, Lake Villa, IL 60046, USATel +1-847-356-0700Fax +1-847-356-0757Email mjlaserdoc@msn.comPurpose: 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.Keywords: optimum refractive target, bilateral EDOF IOL implantation, best myopic target in non-dominant eyes, optimum visual outcomes across all ranges |
