Comparative Evaluation of Visual Outcomes in Combined Cataract and Vitrectomy for Idiopathic Epiretinal Membrane with an Advanced or Conventional Intraocular Lens.

INTRODUCTION: The aim of this study was to investigate the efficacy of new monofocal intraocular lens (IOL) in comparison with conventional monofocal IOL in patients undergoing combined cataract and vitrectomy surgery for epiretinal membrane (ERM). METHODS: This prospective non-randomized comparative study included 65 eyes of 65 patients who underwent combined cataract and vitrectomy for ERM with implantation of advanced monofocal IOL (Eyhance ICB00, 33 patients) and standard monofocal IOL (Tecnis ZCB00, 32 patients). Monocular visual acuities were measured 6 months post-operatively, including corrected and uncorrected distance visual acuity (CDVA, UCDVA), uncorrected intermediate visual acuity (UCIVA), and uncorrected near visual acuity (UCNVA). Furthermore, contrast sensitivity and metamorphopsia were measured. RESULTS: There was no significant difference between two groups regarding operation time, post-operative CDVA, UCDVA, UCNVA, and spherical equivalent (p > 0.05). Monocular UCIVA was significantly higher in the Eyhance IOL group than in the Tecnis IOL group (p = 0.005). The photopic and mesopic contrast sensitivities were comparable between each group for any spatial frequency (p > 0.05). The correlation coefficients from correlations between retinal wrinkling ratio and M score did not differ significantly between groups (p = 0.877), and the degree of metamorphopsia was not significantly related to the type of IOL (p = 0.969). CONCLUSIONS: In combined cataract and vitrectomy for ERM, Eyhance IOL provided significant better visual performance at intermediate distance than standard monofocal IOL without compromising operation time, distance vision, contrast sensitivity, and evaluating metamorphopsia. Eyhance IOL can be a useful option for both surgeons and patients.

Cataract surgery with new monofocal intraocular lens enhanced for intermediate vision and standard monofocal intraocular lens for retinal disorder.

AIM: To investigate the difference in the initial surgical results between a new monofocal intraocular lens (IOL) with enhanced intermediate vision and the standard monofocal IOL in patients with retinal disease. METHODS: We retrospectively reviewed the medical records of patients with retinal disease who underwent cataract surgery due to accompanying cataracts. Types of retinal diseases were investigated and best-corrected distant visual acuity, distant uncorrected visual acuity (UCVA), intermediate UCVA, near UCVA, and spherical equivalent were recorded at each visit. The surgical results were investigated at 1 day, 1 week, and 1 month after surgery. RESULTS: Seventeen eyes treated with a new monofocal IOL enhanced for intermediate vision (ICB00 group) and 18 eyes treated with the standard monofocal IOL (AAB00 group) were included in this study. There were no significant differences in the baseline characteristics, including the type of underlying retinal disease, between the groups. There were no significant differences between the groups in terms of distant, intermediate, or near UCVA at day 1 and week 1 after surgery. However, at 1 month after surgery, the ICB00 group showed a significantly better intermediate vision improvement than the AAB00 group (p = 0.001). CONCLUSION: Even in patients with cataract accompanied by retinal disease, the use of the ICB00 IOL showed significant improvement in intermediate vision compared to the use of the AAB00 (standard monofocal) IOL. The ICB00 IOL might be a good option for patients with cataract and retinal disease in the era of increased intermediate vision needs in daily life.

Visual outcomes and patient satisfaction after bilateral implantation of an enhanced monofocal intraocular lens: a single-masked prospective randomized study.

PURPOSE: To evaluate and compare the visual outcomes of an enhanced monofocal intraocular lens (IOL) with two different monofocal IOLs. SETTING: Eye Clinic, Department of Medicine, Surgery and Health Sciences, University of Trieste, Trieste, Italy. DESIGN: Prospective, single-center, single-masked, randomized controlled clinical study. METHODS: The study included patients undergoing phacoemulsification and IOL implantation. Patients were consecutively randomized by block randomization and assigned in a 1:1:1 allocation ratio to three study arms to bilaterally receive Tecnis Eyhance™ (model ICB00) or Tecnis® monofocal 1-piece (model PCB00) or Clareon® monofocal (model CNA0T0), respectively. Monocular and binocular (both corrected and uncorrected) visual acuities for far, intermediate and near were registered and compared among groups at 3 months. To track changes in patient quality of life, the Catquest-9SF questionnaire was administered to each patient before and after cataract extraction. RESULTS: Ninety patients (30 for each group) were enrolled. At 3 months follow-up, statistically significant differences for intermediate visual acuities were found between the three groups. Nonstatistically significant differences were observed for distance visual acuities and the changes in Catquest-9SF scores. CONCLUSION: Tecnis Eyhance™ provided better results in intermediate visual outcomes without adverse effects on patients' quality of life.

A comparative study of two presbyopia-correcting intraocular lenses combining bifocal and extended depth-of-focus profiles.

OBJECTIVE: To compare the visual performance of two presbyopia-correcting intraocular lenses (IOLs) that combine both bifocal and extended depth-of-focus profiles, Artis® Symbiose® Plus (Symbiose Plus; Cristalens Industrie, Lannion, France) and Tecnis® Synergy® (Synergy; Johnson & Johnson Vision, Santa Ana, CA, USA). METHODS: The medical records of patients with cataract bilaterally implanted with either Symbiose Plus or Synergy between January 2022 and January 2023 were assessed. The principal measures of postoperative findings included uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), uncorrected intermediate visual acuity (UIVA), uncorrected near (40 and 33 cm) visual acuity (UNVA), objective optical quality (OOQ) parameters, distance-corrected defocus curve analysis, and surveys of subjective satisfaction. RESULTS: Total of 96 eyes from 48 patients were enrolled. Each group was equally composed of 24 patients, 48 eyes. There were no significant differences between the two groups on baseline characteristics. Both IOLs displayed excellent binocular UDVA, CDVA, and UNVA (40 and 33 cm) with no statistical difference (p = 0.467(UDVA), p = 0.584(CDVA), p = 0.096(40-cm UNVA), and p = 0.621(33-cm UNVA)). However, with regard to UIVA, the Synergy group showed significantly superior results (p < 0.001). In contrast, the Symbiose Plus group showed significantly better results on OOQ parameters and patient-reported quality of vision survey outcomes (both p < 0.001). CONCLUSIONS: Both IOLs provided a decent continuous range of vision from near to far distance.

Visual and optical quality of enhanced intermediate monofocal versus standard monofocal intraocular lens.

PURPOSE: Intraocular lens designs are constantly evolving, trying to obtain more spectacle independence after cataract surgery. This advantage can be linked to some disadvantages, such as optical quality decrease. For that reason, it is important to assess, not only the amount of vision provided but also the quality of vision once they are implanted. The purpose of the present work was to compare the visual performance between two monofocal intraocular models: a standard model and a monofocal with enhanced intermediate vision lens. METHODS: Prospective, randomized, comparative study. Sixty adult subjects scheduled to undergo bilateral cataract surgery and IOL implantation were randomized to receive one of the two IOLs in both eyes at Miranza IOA, Madrid, Spain (group A: monofocal with enhanced intermediate vision lens and group B: standard monofocal lens). Monocular outcomes (right eyes) determined 1 and 3 months postoperatively were photopic corrected distance visual acuity (CDVA), uncorrected distance visual acuity (UDVA), perceived halo, corrected intermediate-distance contrast sensitivity, and higher-order aberrations. The impact of the new IOL in the postoperative management with autorefraction devices was also evaluated. RESULTS: No differences were found in CDVA between the two groups. Significant differences were detected between the two lenses evaluated in both total HOA (p = 0.028) and internal HOA (p = 0.037). Contrast sensitivity and halometry results obtained at 1 month were similar across the two IOL groups. CONCLUSION: In patients undergoing cataract surgery, monofocal with enhanced intermediate vision IOL offered similar distance performance and contrast sensitivity along with perceived HOA and halos compared with the standard monofocal IOLs tested.

Comparative analysis of a presbyopia-correcting intraocular lens that combines extended depth-of-focus and bifocal profiles with a standard monofocal intraocular lens.

BACKGROUND: Recently, a new presbyopia-correcting intraocular lens (IOL) that combines extended depth-of-focus and bifocal profiles (ZFR00: Tecnis® Synergy®, Johnson & Johnson Vision, Santa Ana, CA, USA) has been established and several studies have been reported. We attempted to compare the performance with a standard IOL (ZCB00: Tecnis® monofocal, Johnson & Johnson Vision, Santa Ana, CA, USA) manufactured using the same material from the same company, which has been extensively used worldwide. METHODS: The medical records of patients undergoing cataract surgery with ZCB00 or ZFR00 implantation between March 2021 and September 2021 and with available 3-month visit data were reviewed. Uncorrected near, intermediate, and distance visual acuity (VA), corrected distance VA, and optical quality were the main outcome measures. RESULTS: This study included forty-six patients (64 eyes), with twenty-one patients (32 eyes) implanted with ZCB00 and twenty-five patients (32 eyes) implanted with ZFR00. The average age of the patients was 66.0 ± 10.1 (range: 40 to 82) and 65.1 ± 4.7 (range: 59 to 77) years in the ZCB00 and ZFR00 groups, respectively. The preoperative characteristics did not differ significantly between the two groups. Compared to the ZCB00 group, the ZFR00 group demonstrated significantly superior intermediate and near VA (p < 0.001) at 3 months postoperatively. The ZFR00 group showed significantly lower objective measured optical quality than that in the ZCB00 group. CONCLUSIONS: The ZFR00 exhibited a continuous range of vision and a smooth defocus curve, while the ZCB00 provided superior objective optical quality.

Comparison of new monofocal innovative and standard monofocal intraocular lens after phacoemulsification.

PURPOSE: To evaluate the early findings of new monofocal intraocular lens (Tecnis® Eyhance) in comparison with standard monofocal intraocular lens (Tecnis® 1-piece) in patients who underwent cataract surgery. METHODS: Sixty-four eyes of thirty-two patients (each intraocular lens model was implanted bilaterally in 16 patients) were included in this retrospective study. Preoperative and postoperative (at one month) manifest refraction, spherical equivalent (SE) values, monocular and binocular uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), uncorrected intermediate visual acuity (UCIVA), distance-corrected intermediate visual acuity (DCIVA), distance-corrected near visual acuity (DCNVA), binocular defocus curve, photopic contrast-sensitivity, spectacle independence, photic phenomena, tolerance to residual refractive errors and complications were recorded. RESULTS: The mean monocular postoperative UDVA, CDVA, DCNVA, spherical equivalent and cylinder values were comparable between each group (p > 0.05). Monocular and binocular DCIVA and UCIVA were significantly higher in Tecnis® Eyhance group than Tecnis® 1-piece group (p = 0.033, p = 0.038, respectively). No statistically significant difference was detected between groups regarding the photopic contrast sensitivities for any spatial frequency (p > 0.05). Spectacle independence was significantly higher in Tecnis® Eyhance group than Tecnis® 1-piece group. Tecnis® Eyhance IOL revealed a good tolerance to unexpected residual refractive errors than Tecnis® 1-piece IOL. CONCLUSION: Tecnis® Eyhance appears to be an effective option for both patients and surgeons regarding better intermediate visual acuities and more forgiving for residual refractive errors relative to the standard monofocal intraocular lenses. However, longer follow-up studies with larger group of patients are needed to evaluate the effectiveness of Tecnis® Eyhance intraocular lens.

Holistic processing and face expertise after pediatric resection of occipitotemporal cortex.

The nature and extent of hemispheric lateralization and its potential for reorganization continues to be debated, although there is general agreement that there is a right hemisphere (RH) advantage for face processing in human adults. Here, we examined face processing and its lateralization in individuals with a single preserved occipitotemporal cortex (OTC), either in the RH or left hemisphere (LH), following early childhood resection for the management of drug-resistant epilepsy. The matched controls and those with a lesion outside of OTC evinced the standard superiority in processing upright over inverted faces and the reverse sensitivity to a nonface category (bicycles). In contrast, the LH and the RH patient groups were significantly less accurate than the controls and showed mild orientation sensitivities at best (and not always in the predicted directions). For the two patient groups, the accuracies of face and bicycle processing did not differ from each other and were not obviously related to performance on intermediate level global form tasks with, again, poorer thresholds for both patient groups than controls and no difference between the patient groups. These findings shed light on the complexity of hemispheric lateralization and face and nonface object processing in individuals following surgical resection of OTC. Overall, this study highlights the unique dynamics and potential for plasticity in those with childhood cortical resection.

Enhanced Monofocal Intraocular Lenses in Fuchs' Endothelial Dystrophy Patients: Results from Triple Descemet Membrane Endothelial Keratoplasty Procedure.

PURPOSE: Descemet membrane endothelial keratoplasty (DMEK) is currently regarded as the most effective surgical procedure for addressing Fuchs Endothelial Corneal Dystrophy (FECD), frequently performed in conjunction with cataract surgery. In this retrospective study, we present a comparison of visual performance, clinical outcomes, and optical quality between two types of monofocal Intraocular Lenses (IOLs): one standard and one enhanced intermediate vision model, implanted in patients who underwent combined phacoemulsification and DMEK surgery. METHODS: This single center comparative retrospective study was conducted at the Eye Clinic of the University of Florence (Italy) and included a total of 48 eyes of 48 patients affected by FECD and cataract. All patients underwent combined DMEK with phacoemulsification procedures. The patients' data were analyzed and divided into two groups: one group (standard group) consisted of 24 eyes that underwent phaco-DMEK with implantation of a monofocal IOL, and the second group (enhanced monofocal group) included 24 eyes that underwent phaco-DMEK with implantation of an enhanced monofocal IOL. In both groups, the following monocular visual outcomes were evaluated 6 months after surgery: Uncorrected Distance Visual Acuity (UDVA) and Best-Corrected Distance Visual Acuity (BCDVA) at 4 mts; Uncorrected Intermediate Visual Acuity (UIVA), Distance-Corrected Intermediate Visual Acuity (DCIVA) at 66 cm; Uncorrected Near Visual Acuity (UNVA) and Best Corrected Near Visual Acuity (BCNVA). Monocular defocus curves were also assessed. Furthermore, optical quality in terms of Contrast Sensitivity (CS) in photopic conditions, Higher-Order Aberrations (HOAs) at a pupil size of 5 mm. Modulation Transfer Function (MTF), Objective Scatter Index (OSI), and Strehl ratio, were also analyzed. A Patient-Reported Spectacle Independence Questionnaire was revised to evaluate spectacle independence outcomes. RESULTS: the two groups did not exhibit statistically significant differences in terms of UDVA, BCDVA, UNVA and BCNVA, photopic CS, HOAs, OSI, Strehl ratio, and MTF. However, in the phaco-DMEK enhanced monofocal IOL group, significantly better results were observed in terms of UIVA and DCIVA as well as a different defocus curve profile at 1.50 D, providing better defocus results at intermediate distance compared with the ZCB00 IOL. CONCLUSION: In our study, we found that enhanced monofocal lens performed favorable visual outcomes, even in cases of FECD, compared to standard monofocal IOLs. Comparable optical quality observed in the Eyhance group could allow surgeons to consider these lenses as a viable option for selected patients with FECD.

Reliability of self-measurement of visual acuity in AMD patients with two electronic devices based on the ETDRS chart: A randomized study.

INTRODUCTION: Age-related macular degeneration (AMD) requires continuous visual acuity (VA) monitoring, increasing the burden on the health care system. Self-measurement VA tests are available on various devices. However, none of them have been based on an internationally validated benchmark chart, such as that of the Early Treatment Diabetic Retinopathy Study (ETDRS). The goal of this study was to assess the reliability of two digitized ETDRS charts adapted to two electronic devices for self-measurement of VA. MATERIAL AND METHODS: A prospective, single-center, 1:1 randomized, two-arm, parallel group trial was conducted. The main objective was to compare VA variation as conventionally measured on a 4-m ETDRS chart versus self-measured with digitized ETDRS charts in patients treated for AMD. At each visit, conventional measurement and patient self-measurement, either on a computer at 80-cm (arm 1) or on a tablet at 40-cm (arm 2), were performed. RESULTS: Eighty patients were included (25 men, 55 women, mean age 81.3±7.4 years). No significant differences were observed between VA variation, conventionally measured and self-measured on a computer (arm 1; P=0.914) or tablet (arm 2; P=0.913). CONCLUSION: These results confirm the reliability of these two methods for self-measurement of VA, and will lead to the development of a wider "telemedicine" project extended to self-measurement of VA in various pathologies.

Investigating the interaction between low and intermediate levels of spatial vision at different periods of development.

Although much research has investigated the visual development of lower (local) and higher levels (global) of processing in isolation, less is known about the developmental interactions between mechanisms mediating early- and intermediate-level vision. The objective of this study was to evaluate the development of intermediate-level vision by assessing the ability to discriminate circular shapes (global) whose contour was defined by different local attributes: luminance and texture. School-aged children, adolescents, and adults were asked to discriminate a deformed circle (radial frequency patterns or RFP) from a circle. RFPs varied as a function of (a) number of bumps or curvatures (radial frequency of three, five, and 10) and (b) the physical attribute (luminance or texture) that defined the contour. Deformation thresholds were measured for each radial frequency and attribute condition. In general, results indicated that when compared to adolescents and adults children performed worse only when luminance-defined shapes had fewer curvatures (i.e., three and five), but for texture-defined shapes, children performed worse across all types of radial frequencies (three, five, and 10). This suggests that sensitivity to global shapes mediated by intermediate level vision is differentially affected by the type of local information defining the global shape at different periods of development.

Improvement of intermediate vision with new monofocal intraocular lenses: A systematic review and meta-analysis.

PURPOSE: Monofocal intraocular lenses (IOLs) used in cataract surgery are designed to improve visual acuity (VA). The available evidence of new monofocal IOLs" functional benefits is limited. The aim of this meta-analysis was to analyze the improvement in VA using Tecnis Eyhance monofocal IOLs compared to standard monofocal IOLs Tecnis ZCB00. METHODS: MEDLINE, Web of Science and Scopus were searched for studies assessing improvement in intermediate VA using Tecnis Eyhance IOLs versus Tecnis ZCB00 IOLs. Studies evaluating post-operative VA in patients who underwent cataract surgery were selected. This meta-analysis followed PRISMA guidelines and was registered in PROSPERO. The Cochrane Risk of Bias Tool 2.0. was used to assess the methodological quality of the included studies, risk of selection bias and comparability of cohorts and outcomes. RESULTS: The search resulted in 1153 articles. Five studies met the inclusion criteria and were included in the meta-analysis. A total of 604 eyes were evaluated, of which 309 received Tecnis Eyhance IOLs and 295 were implanted with Tecnis ZCB00 IOLs. Mean binocular distant-corrected intermediate VA with Tecnis Eyhance IOLs at 2 weeks-1 month showed a significant difference of -0,21 logMAR, p < 0.001; and mean binocular distance-corrected intermediate VA with Tecnis Eyhance IOLs at 6 months showed a significant difference of -0,11 logMAR, p < 0.001. CONCLUSION: Near VA could not be assessed in this meta-analysis as it was measured in very few studies. Preliminary pooled evidence indicates that intermediate VA improved with Tecnis Eyhance IOLs. Further studies evaluating near VA and with longer follow-up are still necessary.

Clinical Performance of New Enhanced Monofocal Intraocular Lenses: Comparison of Hydrophobic C-loop and Hydrophilic Plate-Haptic Platform.

INTRODUCTION: Enhanced monofocal intraocular lenses (IOLs) represent a new type of lens, which should lead to a very good distance vision similar to monofocal IOLs and an improved intermediate vision without increasing the risk for photic phenomena. METHODS: The aim of this clinical observation/registry study was to directly compare two different IOL platforms (hydrophilic acrylic L-333 (group A) vs hydrophobic acrylic AN6Q (group B)) with the same enhanced monofocal optic principle but different material and haptic design in clinical routine. A total of 102 cataract cases (51:51) were included in the study. Groups A and B were similar regarding demographics, age (71.6 ± 9 years for L-333 and 73.6 ± 8 years for AN6Q) and their calculated IOL power (20.9 ± 2.0 D for L-333 and 21.5 ± 3.4 D for AN6Q). Spherical equivalent (SE), (un)corrected distance, intermediate visual acuity, the surgeons' experience and patient feedback were assessed postoperatively. RESULTS: SE improved significantly in the AN6Q group, while the L-333 group showed a slightly smaller standard deviation postoperatively. In group A the uncorrected distance visual acuity (UDVA) improved from pre-op (0.43 ± 0.16 logMAR) to 1 month post-op (0.06 ± 0.04 logMAR) significantly and in group B from pre-op (0.54 ± 0.19 logMAR) to (0.05 ± 0.06 logMAR) postoperatively. Both groups showed excellent outcomes for distance without negative side effects. On testing uncorrected intermediate vision (80 cm) with Radner charts, 80% reached line 5 (0.0 logRAD) with fewer than one mistake and 10% reached line 4 (- 0.1 logRAD) in group A; 74% reached line 5 with fewer than one mistake and 4% reached line 4 in group B. CONCLUSION: Both IOL models (groups A and B) provided satisfying results regarding implantation behaviour, refractive error, visual acuity and overall patient satisfaction. The haptic design might influence the outcome of refractive error. Long-term follow-up data should be considered in multicentre studies to further characterize both platforms and to optimize IOL power calculation (constants, surgeon factor). It was shown that the enhanced monofocal optic can provide good visual acuity for far distance and improve intermediate distance. This type of new monofocal optic design, which however must be strictly separated from typical refractive/diffractive multifocal, presbyopia-correcting lenses, could be a good option in standard cataract care.

The BVI ISOPURE® 123 intraocular lens: a new hydrophobic preloaded extended monofocal IOL with intermediate vision correction.

The BVI ISOPURE® intraocular lens (IOL) (PhysIOL, Liege, Belgium) is a fully refractive, aspherical, monofocal lens based on isofocal technology. Isofocal technology provides cataract patients distance vision quality combined with improved unaided intermediate vision by accentuating the extended depth of field/focus (EDOF) effect whilst inducing minimal photic phenomena. Methods: PubMed, Web of Science, Scopus, and Google Scholar searches were conducted for published research articles featuring the ISOPURE 123 IOL. Results: Excellent uncorrected and corrected binocular distance visual acuity of at least 20/25 can be achieved; uncorrected binocular intermediate vision of 20/25 or better in 81% and 50% at 80 cm and 66 cm, respectively, and 42% binocular near vision of 20/40 or better can be achieved. The defocus curve showed good visual acuity at far and intermediate distances with a depth of focus value of 1.50 D. Photic phenomena are minimal compared to other EDOF IOLs. Excellent contrast sensitivity was maintained compared to a standard monofocal IOL. Conclusion: Studies show that this isofocal optic design IOL provides excellent visual performance for far vision and functional intermediate vision with an increased range of vision with few photic phenomena. This lens is an effective option for providing functional intermediate vision and correcting aphakia.

Clinical Results and Factors Affecting Visual Function in Eyes Implanted with an Enhanced Monofocal Intraocular Lens.

Purpose: To compare the clinical results achieved with the enhanced monofocal intraocular lenses (IOLs) with those of the monofocal IOL and investigate factors affecting the distance, intermediate, and near vision. Patients and Methods: Patients were included who underwent bilateral consecutive cataract surgeries using the same IOLs with follow-up to 1 month postoperatively. Refractions, monocular UDVA and CDVA, and binocular distance-corrected functional visual acuity at 5 meters (BDCFVA), at 66 centimeters (BDCIFVA) and at 40 centimeters (DCNVA) were assessed. Multiple regression analysis was used to assess the factors affecting binocular BDCFVA, BDCIFVA, and BDCNFVA. Subjective symptoms were assessed using the Near Activity Visual Questionnaire (NAVQ) and visual analogue scale (VAS). Results: Sixty patients (120 eyes) implanted with the Tecnis Eyhance IOL (30 patients, 60 eyes) or the Tecnis monofocal IOL (30 patients, 60 eyes) were included. The Tecnis Eyhance IOL provided significantly better binocular BDCIFVA than the Tecnis monofocal IOL in patients under 70 years of age. Multiple regression analysis showed that age was the only factor affecting distance and intermediate visual function in eyes with the Tecnis Eyhance IOL; gender, pupillary diameter, axial length, and average keratometry were not significant. There were no significant differences in subjective symptoms. Conclusion: The comprehensive cohort analysis did not confirm the advantage on the intermediate vision of the Tecnis Eyhance IOL. Younger age may be an important factor to benefit from the unique optical characteristics of this IOL.

Extended depth of focus intraocular lens versus a new monofocal intraocular lens: A prospective comparative and interventional study.

PURPOSE: To compare the visual outcome findings between a new monofocal intraocular lens (IOL) (Tecnis Eyhance) and extended depth of focus (EDOF) IOL (Appasamy Supraphob Infocus). METHODS: This prospective comparative interventional study evaluated 31 patients after implantation of Tecnis Eyhance (15 patients) and Supraphob EDOF IOL (16 patients). The uncorrected and corrected distance and intermediate and near visual acuity were measured at postoperative day 1, 1 week, 4 week, and 3 months. Contrast sensitivity, incidence of halos and glares, and patient satisfaction were assessed at 3 months postoperatively. RESULTS: The Tecnis Eyhance (n = 15) and Supraphob EDOF (n = 16) group were comparable with respect to all preoperative parameters including biometry, visual acuity, and cataract status. The average age distribution of participants was 56 ± 6 years. Postoperatively, both groups had similar distance and intermediate vision, but the near vision was significantly better in the EDOF group (P < 0.01) as compared to Tecnis Eyhance at 3 months. The contrast sensitivity and patient satisfaction were similar in both the groups. The incidence of halos and glares was present in the EDOF group, but it was statistically insignificant. CONCLUSION: The Tecnis Eyhance and Supraphob EDOF both were effective in improving distance and intermediate vision, but the near vision was significantly better in the EDOF group. Both the groups retained good contrast sensitivity and the majority of patients were satisfied.

Orientation of the intermediate-vision zone of rotationally asymmetric multifocal intraocular lenses and photic phenomena.

PURPOSE: To evaluate the association between the orientation of the intermediate-vision zone and postoperative photic phenomena in eyes implanted with rotationally asymmetric multifocal intraocular lenses with + 1.5 diopters near addition. STUDY DESIGN: Retrospective comparative case series. METHODS: We performed the photic phenomena test (PPT) to quantitatively evaluate photic phenomena at 1-3 months after cataract surgery with Lentis Comfort LS-313 MF15 or Lentis Comfort Toric LS-313 MF15T insertion (Oculentis; Santen Pharmaceutical). In cases of bilateral surgeries, only the right eye was included in the analysis. We also conducted a questionnaire survey about the photic phenomena. RESULTS: The study included 96 eyes from 96 patients. The intermediate-vision zones of 44, 19, 19, and 14 eyes were fixed in the inferior, superior, nasal, and temporal directions, respectively. The measured PPT values for halo, glare, and starburst were equivalent in all the fixed directions. Eighty-four eyes (87.5%) perceived a triangle-shaped halo, and the direction of fixation for the intermediate-vision zone and the extension direction of this photic phenomenon were consistent in 94.0% of the eyes. Less than 10% of the patients responded "moderate" or "severe" for the triangle-shaped halo, glare, and starburst in fixed directions with low frequency in the questionnaire. CONCLUSION: No qualitative or quantitative difference was found in photic phenomena in eyes implanted with the LS-313 MF15 or the MF15T regardless of the fixation direction. Our study revealed that many patients were aware of a triangle-shaped halo extending in the direction of the intermediate-vision zone.

Evaluation of a New Monofocal Intraocular Lens in Patients Undergoing Cataract and Vitrectomy Surgery for Idiopathic Macular Hole.

PURPOSE: To evaluate the usefulness of a newly generated monofocal intraocular lens (IOL) in patients who underwent combined cataract and pars plana vitrectomy (PPV) surgery for idiopathic macular hole (MH). METHODS: A prospective study was conducted on 89 eyes of 89 patients who underwent combined cataract and PPV surgery for MH. The patients were divided into two groups: Eyhance ICB00 and Tecnis ZCB00. Pre-operative characteristics, post-operative visual outcomes, contrast sensitivity, and complications were compared between the two groups. A univariate regression analysis was performed to identify the factors that may affect the postoperative visual outcomes. RESULTS: Both groups showed significant improvement in mean corrected distance visual acuity (CDVA) six months post-operation (p < 0.001). There was no significant difference in pre-operative characteristics or complications between the two groups. However, the Eyhance ICB00 group showed a significantly higher uncorrected intermediate visual acuity (UCIVA) value at 6 months after surgery than the Tecnis ZCB00 group (p = 0.014). Contrast sensitivity values were not significantly different between the two groups. The univariate regression analysis revealed a significant correlation between preoperative CDVA and minimum linear diameter of MH with postoperative UCIVA in the Eyhance ICB00 group. CONCLUSIONS: The newly generated Eyhance ICB00 IOL showed promising results in terms of post-operative UCIVA, with no significant difference in complications or contrast sensitivity values compared to the Tecnis ZCB00 IOL. These findings suggest that the Eyhance ICB00 IOL may be a useful option for patients who undergo combined cataract and PPV surgery for idiopathic MH, particularly for those who require intermediate visual acuity.

Improved Intermediate Visual Function with New Monofocal Intraocular Lens in Combined Cataract and Vitrectomy Surgery for Retinal Disease.

PURPOSE: To evaluate the usefulness of a newly generated monofocal intraocular lens (IOL) in patients with various retinal diseases who underwent combined cataract and pars plana vitrectomy surgery. METHODS: This prospective observational study included 33 patients with various retinal diseases. Monocular best-corrected distance visual acuity (BCDVA), uncorrected distance visual acuity (UCDVA), uncorrected intermediate visual acuity (UCIVA), uncorrected near visual acuity (UCNVA), and contrast sensitivity were measured and compared with 40 age-matched patients in the standard monofocal IOL. RESULTS: The Eyhance IOL group demonstrated significantly better UCIVA at 6 months follow-up compared to the standard monofocal IOL group. No significant differences were observed between the two groups in contrast sensitivity, BCDVA, UCDVA, or UCNVA. The regression analysis showed a significant association between preoperative corrected distance visual acuity and improved UCIVA in the Eyhance IOL group. CONCLUSIONS: The Eyhance ICB00 IOL proved to be a valuable option for patients with retinal diseases undergoing combined cataract surgery and vitrectomy. It effectively improved intermediate vision without compromising contrast sensitivity or distance visual acuity.

Comparative evaluation of visual outcomes after bilateral implantation of an advanced or conventional monofocal intraocular lens.

PURPOSE: To assess the clinical outcomes and patient satisfaction of the Tecnis Eyhance, an advanced monofocal intraocular lens (IOL), compared to a conventional monofocal IOL. DESIGN: Retrospective case-control study. METHODS: This study included 120 eyes of 60 patients (30 patients in each group) who underwent bilateral cataract surgery either with the implantation of conventional monofocal IOLs (Tecnis PCB00), as a control group, or advanced monofocal IOLs (Tecnis Eyhance ICB00). Ophthalmological evaluation included the measurement of binocular corrected distance visual acuity (CDVA), monocular and binocular uncorrected distance visual acuity (UDVA), and uncorrected intermediate VA (UIVA). In addition the binocular defocus curve was analyzed. Furthermore a subjective questionnaire (Catquest-9SF) was used to assess vision and life quality. RESULTS: The average binocular UDVA was 20/22 in the ICB00 group and 20/20 in the PCB00 model (p = 0.62). The average monocular UIVA was 20/32 in the ICB00 group and 20/40 in the control group (p < 0.001). We found the binocular UIVA, had a mean value of 20/30 in the ICB00, compared to 20/40 in the control group (p < 0.001). The reported dysphotopsia was not significantly different between both groups (p = 0.56). Regarding the life quality questionnaire, the ICB00 group showed less difficulty in activities requiring intermediate vision. CONCLUSION: Our results demonstrated a significant improvement in visual acuity for intermediate distance in the ICB00 group compared to the control group, without compromising distance visual acuity. We also found a greater capability for intermediate distance activities (namely for computer use and reading price tags) when comparing ICB00 patients with the control group.
