“…20 Median logMAR binocular UNVA at 6 months was 0.21 (0.15-0.3, IQR), whereas mean logMAR binocular DCNVA was 0.27 (0.21-0.37, IQR). This decrease in DCNVA These VA results are comparable with the results of Tahmaz et al, 19 21 Another IOL of similar design is the Elon IOL (Medicontur); however, to the authors' knowledge, the scientific literature does not yet report results for this IOL.

Background: Extended depth-of-focus (EDOF) intraocular lenses (IOLs) provide a continuous range of uncorrected vision at different distances. Objective: To assess visual acuity, refractive outcomes, and patient satisfaction after cataract surgery using the LuxSmart EDOF IOL (Bausch+Lomb). Design: A two-center, prospective observational clinical study. Methods: This study includes patients who have undergone bilateral phacoemulsification with bilateral implantation of the LuxSmart EDOF IOL, with the aim of achieving emmetropia. Visual acuity (VA) and subjective refraction were obtained in all patients preoperatively and at 1 week, 1 month, 3 months, and 6 months postoperatively. Subjective measures were obtained using the Catquest-9SF questionnaire and the Patient-Reported Spectacle Independence Questionnaire (PRSIQ). Contrast sensitivity and a glare assessment were undertaken postoperatively. Safety outcomes were additionally assessed. Results: Sixty eyes from thirty patients were recruited for this study. The mean spherical equivalent was 1.04 ± 1.67 D preoperatively and −0.30 ± 0.46 D at 6 months. Monocular uncorrected distance VA was 0.57 ± 0.32 (logMAR) preoperatively and 0.09 ± 0.12 (logMAR) at 6 months. Mean 6-month monocular uncorrected VA was 0.11 ± 0.13, 0.12 ± 0.15, and 0.31 ± 0.15 (logMAR) at 80, 66, and 40 cm, respectively. More than 90% of patients were either fairly or very satisfied with their vision. There was one case of suspected vitreomacular traction postoperatively. Conclusion: The LuxSmart EDOF IOL offers good refractive, VA, and safety outcomes. The single elongated focal point designed to enhance the DOF shows good results for VA and patient satisfaction.

In recent years, there has been an overwhelming influx of different types of intraocular lenses (IOLs) as treatment for presbyopia. The extended depth-of-focus (EDOF) technology creates a single elongated focal point to enhance depth of focus, in contrast to the multiple foci of multifocal (MF) lenses. In this way, the EDOF lenses aim to reduce photic phenomena, glare, and halos, which have been reported in MF IOLs. A potential disadvantage of this is a blur due to decreased retinal image quality when the amount of the aberrations is increased excessively. Multifocality and EDOF characteristics are not exclusive of each other. Frequently, EDOF IOLs are combined with MF optical designs, a bifocal IOL may exhibit EDOF characteristics, likewise an aspheric monofocal IOL or a diffractive or refractive trifocal IOL. Thus, EDOF lenses are commonly subjected to confusion. A wide range of different types of EDOF lenses are available on the market to surgeons. In this practical update, we aim to clarify what is a true EDOF lens, classify the different types of the EDOF lenses based on their optical principle and review their recently reported outcomes. Comprehensive patient examination and selection, combined with knowledge of the most updated options and adequate patient counseling, can avoid dissatisfaction and yield the desired outcomes.

“…18 Reinhard et al and Tahmaz et al both reported an improved depth of field for either a diffractive or non diffractive EDOF IOL compared to aspheric monofocal IOLS. 18,19 Rodov et al reported a significant superiority of EDOF IOLs compared to a monofocal group for depth of field, but added that monofocals used in a monovision approach can provide good depth of field and UDVA. 20 Jeon et al compared a diffractive EDOF IOL (TECNIS Symfony) and a Monofocal plus IOL (Tecnis Eyhance) and found the former offered improved near visual acuity, and the latter offered better optical quality.…”

BackgroundTo evaluate the intraindividual visual performance of a spherical and extended depth of field (EDOF) IOL used in a mix‐and‐match approach.MethodsSingle centre (tertiary care centre), retrospective consecutive case series. Included patients had uneventful cataract surgery with implantation of a spherical monofocal IOL (CT Spheris 204) in the dominant eye and a diffractive EDOF IOL (AT LARA 829) in the non‐dominant eye. Monocular and binocular defocus curves and visual acuity at various distances were assessed. In addition, binocular reading speed, contrast sensitivity, and patient satisfaction using QOV, Catquest 9SF, and glare/halo questionnaires are reported.ResultsA total of 29 patients (58 eyes) were included. We observed significant intra‐individual differences for monocular DCIVA, DCNVA, UIVA, and UNVA. There were no differences in monocular BCDVA or UDVA. The monocular defocus curves for the two IOLs significantly differed at defocus steps between −1.0 and −3.5 D. 93.10% of patients reported they would opt for the same combination of IOLs.ConclusionExcellent uncorrected and corrected distance visual acuity was demonstrated in both groups. The mix‐and‐match approach described in this study yielded good intermediate vision and improved near vision with high‐patient satisfaction.
