Abstract
Patients who suffer from sight-threatening eye diseases share a desire to regain a comfortable reading ability. In light of the modern advances achieved in ophthalmic diagnosis and therapy, and because a significant lack of comparability between reading charts still exists, there is an increasing need for a worldwide standard in the form of a norm for diagnostic reading charts. Already, applied advancements such as digital print, which allow a calibration of the print sizes of reading charts in correctly progressing geometric proportions by using the actual height of a lower case "x" in millimeters (x-height), and psychophysically standardizing reading charts and their test items by applying modern statistical methods have significantly contributed to establishing a norm for reading charts. In 2020, a proposal of the British delegation was accepted by the International Organization for Standardization (ISO) group "Visual Optics and Optical Instruments," and a working group was established. Bearing in mind the efforts of the ISO with regard to an international norm, this review article is intended to (a) give an overview of the historical background and related normative approaches for diagnostic reading tests used in ophthalmology and optometry, (b) explain psychophysical and technical concerns, and (c) discuss the possibilities and limits of concepts that seem relevant to developing a modern standard for reading charts.

Abstract
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.

[PMID: 37440544 DOI: 10.1371/journal.pone.0288602] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/18/2022] [Accepted: 07/02/2023] [Indexed: 07/15/2023] Open
Abstract
We compared the visual performance of a bifocal intraocular lens (IOL) (ZMB00) and an extended-depth-of-focus (EDOF) IOL (ZXR00V) by evaluating postoperative parameters at 10 weeks after the last surgery in cataract patients who underwent bilateral ZMB00 or ZXR00V implantation between 2011 and 2020. The right and left lenses were implanted within 3 months of each other. The study enrolled 1536 eyes of 768 patients; the ZMB00 group comprised 1326 eyes of 663 patients (age: 67.0 ± 7.8 years; female/male, 518/145), and the ZXR00V group comprised 210 eyes of 105 patients (age: 67.8 ± 6.9 years; female/male, 39/66). A linear mixed-effects model using data for both eyes, with strict adjustments for sex, age, subjective refraction spherical equivalent, subjective refraction cylinder, corneal astigmatism, axial length, corneal higher-order aberrations and pupil diameter, ensured statistical validity. Uncorrected near visual acuity, corrected near visual acuity, and near spectacle independence were significantly better in the ZMB00 group (p<0.00068, Wald test) than in the ZXR00V group. Contrast sensitivity (visual angle of the test target: 4.0°/2.5°/1.6°/1.0°/0.7°) and contrast sensitivity with glare (4.0°/2.5°/1.6°/1.0°/0.7°) were significantly better in the ZXR00V group (p<0.00068, Wald test) than in the ZMB00 group. Uncorrected intermediate visual acuity, contrast sensitivity with glare (6.3°), and 25-item National Eye Institute Visual Function Questionnaire (VFQ-25) scores for General Vision were slightly but significantly better in the ZXR00V group than in the ZMB00 group (p<0.05, Wald test). At high-performance levels, the two IOL groups had different characteristics regarding various visual performance parameters.

Graefes Arch Clin Exp Ophthalmol 2022; 260:3275-3283. [PMID: 35633381 DOI: 10.1007/s00417-022-05710-w] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/20/2022] [Revised: 05/03/2022] [Accepted: 05/14/2022] [Indexed: 11/04/2022] Open
Abstract
PURPOSE To compare visual outcomes between two types of mix-and-match implanted trifocal extended-depth-of-focus (EDoF) and trifocal intraocular lenses (IOLs). METHODS A total of 212 eyes of 106 subjects with mix-and-match implanted FineVision Triumf and FineVision HP IOLs (Triumf-HP group) and 212 eyes of 106 subjects with mix-and-match implanted Zeiss AT LARA and AT LISA IOLs (AT LARA-LISA group) were enrolled in this retrospective case-control study. Uncorrected distance visual acuity (UDVA), uncorrected near visual acuity (UNVA), and binocular distance-corrected defocus curves were measured between 6 and 10 weeks after cataract surgery. RESULTS There was no significant difference in UDVA among the four IOLs. UNVA was the best in eyes with the FineVision HP IOL (0.04 ± 0.06 logMAR), followed by eyes with the AT LISA IOL (0.07 ± 0.07 logMAR), the FineVision Triumf IOL (0.09 ± 0.09 logMAR), and the AT LARA IOL (0.11 ± 0.08 logMAR), respectively. The AT LARA-LISA group had better visual acuity than the Triumf-HP group between - 1.00 D and - 1.50 D of defocus, and the Triumf-HP group had better visual acuity than the AT LARA-LISA group between - 3.00 D and - 4.00 D of defocus. CONCLUSION Mix-and-match implantation of trifocal EDoF and trifocal IOLs provided good visual outcomes in far, intermediate, and near distances. The mix-and-match implantation of Triumf-HP IOLs led to better visual outcomes in near vision, while that of the AT LARA-LISA IOLs led to better visual outcomes in intermediate vision.

Abstract
Purpose To assess the preliminary clinical outcomes and patient satisfaction of the new enhanced depth of focus (EDOF) LuxSmart™ intraocular lens IOL and to compare with a conventional monofocal IOL (Akreos™) in patients who had undergone bilateral cataract surgery. Methods Twelve patients underwent bilateral LuxSmart IOL implantation, and twelve underwent bilateral Akreos IOL implantation. Best-corrected distance (CDVA) and uncorrected distance visual acuity (UDVA), uncorrected intermediate visual acuity (UIVA) at 66cm, uncorrected near visual acuity (UNVA) at 40cm and defocus curve were assessed. Patients-reported visual function was inquired by Catquest-9SF. The presence of photic phenomena was evaluated. A p-value lower than 0.05 was considered for statistical significance. Results The mean IOL power was +21.90D in LuxSmart group and +22.30D in Akreos. Monocular UDVA (p = 0.32) and CDVA (p = 0.52) did not differ between groups. The average binocular UIVA (0.18 ± 0.12 logMAR vs. 0.30 ± 0.13 logMAR, p < 0.001) and UNVA (0.38 ± 0.14 logMAR vs. 0.44 ± 0.17 logMAR, p = 0.02) were higher in LuxSmart IOL group. No patients reported disabling photic phenomena in either group. Conclusion This study shows that new LuxSmart EDOF IOL achieved higher performance for intermediate and near vision compared with a conventional monofocal IOL, without increasing the risk of dysphotopsias. LuxSmart may be an attractive and safe option for patients who desire spectacle independence for distance and intermediate vision after cataract surgery.

Abstract
PURPOSE To evaluate the short-term outcomes of implantation of a full-diffractive multifocal intraocular lens (IOL) with optic capture for selected pediatric cataracts. METHODS In this prospective study, patients with pediatric cataract aged 3 to 14 years were selected to receive multifocal IOL (Tecnis ZMB00; Abbott Medical Optics) posterior optic capture. Visual acuity, stereopsis, visual quality, and complications were assessed. RESULTS Forty-five patients (66 eyes) were recruited with a follow-up of 9.09 ± 5.93 months (range: 6 to 24 months). The cataract was bilateral in 21 patients and unilateral in 24 patients. At the last follow-up visit, the mean distance-corrected distance, intermediate, and near visual acuity was 0.28 ± 0.25, 0.43 ± 0.24, and 0.39 ± 0.27 logMAR, respectively. Among the patients with bilateral cataract, postoperative corrected distance visual acuity (CDVA) was 20/40 or better in 79% (33 of 42) of the eyes and 20/20 in 26% (11 of 42) of the eyes. Of the patients with unilateral cataract, 54% (13 of 24) achieved a CDVA of 20/40 or better but none obtained a CDVA of 20/20. All patients developed stereopsis postoperatively (P < .05). There was no significant difference in modulation transfer function cut-off and Strehl ratio between the eyes with a multifocal IOL and the healthy eyes of patients with unilateral cataract (P > .05). Objective Scatter Index values were significantly better in the healthy eyes (P < .05). No posterior capsule opacification, posterior synechiae, secondary glaucoma, pigmentary IOL deposits, or IOL decentration was observed during the follow-up period. CONCLUSIONS Short-term follow-up results suggest full-diffractive multifocal IOL optic capture may benefit appropriately selected patients with pediatric cataract.

Abstract
PURPOSE To evaluate the clinical effect of TECNIS Symfony intraocular lens (IOL) implantation and identify the effect of kappa angle on the depth of focus (DOF) after implantation. METHODS This prospective clinical study included consecutive patients who underwent cataract surgery and TECNIS Symfony IOL implantation at the Daqing Oilfield General Hospital from January 2019 to September 2019. Patients were divided into three groups according to the preoperative kappa angle (r): A (0 < r ≤ 0.2), B (0.2 < r ≤ 0.4), and C (r > 0.4). Uncorrected visual acuity was performed preoperatively and at 7 days, 1 month, and 3 months postoperatively. Synthetical optometry, higher-order aberrations, and defocus examinations were performed at 3 months postoperatively. Single-factor analysis of variance and Spearman correlation coefficient were used for data analysis. RESULTS The uncorrected visual acuity values of the three groups were significantly improved postoperatively, compared with preoperative values (p < 0.001). Three months postoperatively, the best-corrected visual acuity values of the three groups were 0.11 ± 0.02 logarithm of the minimum angle of resolution (logMAR), 0.09 ± 0.03 logMAR, and 0.11 ± 0.03 logMAR, respectively. Spherical equivalent (SE) values were 0.37 ± 0.08 D, 0.41 ± 0.06 D, and 0.42 ± 0.06 D, respectively. Best-corrected visual acuity and SE did not significantly differ among the three groups (F = 1.254, p = 0.135; F = 0.849, p = 0.228). There was no significant difference in SE between the three groups (F = 1.658, p = 0.312). Moreover, higher-order aberrations did not significantly differ among the three groups (p > 0.05). The kappa angle was negatively correlated with the postoperative DOF (r = -4.341, p = 0.026). Three months postoperatively, 54.55% of patients exhibited DOF ≥ 3 D, while 92.42% of patients exhibited DOF ≥ 2 D. The ranges of DOF in the three groups were 3.18 ± 0.27 D, 2.83 ± 0.80 D, and 2.57 ± 0.89 D, respectively; the difference among the three groups was statistically significant (F = 5.689, p = 0.037). CONCLUSION Most patients achieved full-range vision after TECNIS Symfony IOL implantation, but the DOF narrowed for those with an excessively large kappa angle, which indicates a need for careful selection.

Abstract
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.

Abstract
AIM To evaluate clinical outcomes following implantation of an extended range of vision intraocular lens (IOL), the ZXR00, and a diffractive multifocal IOL with +2.75 diopters (D) add power, the ZKB00. METHODS Totally 30 patients who underwent either bilateral implantation of the ZXR00 IOL with intended emmetropia (ZXR00 emmetropia group: 20 eyes) and intended micromonovision (ZXR00 monovision group: 20 eyes), or bilateral implantation of the ZKB00 IOL with intended emmetropia (ZKB00 group: 20 eyes) were included in this study. Visual acuity at 4 m, 80, and 40 cm; and the types of halos (misty, fine, and rainbow) were analyzed at one and three months after surgery. RESULTS There were no significant differences in distance visual acuity among the three groups. The mean uncorrected intermediate visual acuity was better in the ZXR00 emmetropia and monovision groups (0.02 logMAR and 0.02 logMAR, respectively) than in the ZKB00 group (0.14 logMAR). The mean uncorrected near visual acuity was worse in the ZXR00 emmetropia group (0.26 logMAR) than in the ZXR00 monovision and ZKB00 groups (0.12 logMAR and 0.10 logMAR, respectively). There was an increased incidence of rainbow halos in the ZKB00 group vs in either ZXR00 group (P=0.033). CONCLUSION Implantation of the ZXR00 IOL with intended micromonovision provide superior visual acuity than implantation of the ZXR00 IOL with intended emmetropia. The ZXR00 IOLs tend to show a lower incidence of rainbow halos than did the ZKB00 IOL.

Abstract
PURPOSE To compare clinical outcomes and subjective experience after bilateral implantation of two non-toric diffractive trifocal intraocular lenses (IOLs). METHODS In a prospective, comparative case series, patients were randomly allocated to receive bilateral implantation of either the preloaded RayOne Trifocal (Rayner, Worthing, UK) or the FineVision POD F (PhysIOL, Liège, Belgium). At the 3-month follow-up, the main outcomes were monocular and binocular uncorrected and corrected distance (UDVA, CDVA), intermediate at 80 cm (UIVA, DCIVA), and near at 40 cm (UNVA, DCNVA) visual acuities, refractive outcomes, and defocus curves. Patients' satisfaction in terms of visual disturbance was also evaluated. RESULTS Each group comprised 30 eyes (15 patients). The mean monocular UDVA was 0.03 ± 0.11 (RayOne Trifocal) and 0.04 ± 0.08 (FineVision POD F) logMAR (P = .605); DCIVA was 0.05 ± 0.13 and 0.05 ± 0.10 logMAR, respectively (P > .999); and DCNVA was 0.02 ± 0.12 and 0.03 ± 0.11 logMAR (P = .742). A better manifest spherical equivalent was found in the RayOne Trifocal than in the FineVision POD F group (P = .035) and depth perception issues were less severe with the RayOne Trifocal IOL (P = .042). There was no significant difference in other photic phenomena between groups. CONCLUSIONS Both IOLs provided good visual outcomes at all distances with no differences between the groups. Refractive accuracy was better for the RayOne Trifocal IOL. The results indicated that the new trifocal IOL may represent a safe and effective option for presbyopic patients.

Comparison of the Clinical Outcomes between Echelette Extended Range of Vision and Diffractive Bifocal Intraocular Lenses. J Ophthalmol 2019; 2019:5815040. [PMID: 31662895 PMCID: PMC6778892 DOI: 10.1155/2019/5815040] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/16/2019] [Accepted: 08/20/2019] [Indexed: 11/28/2022] Open
Abstract
Purpose To compare the clinical outcomes of echelette extended range of vision (ERV) and diffractive bifocal intraocular lenses (IOLs). Methods This is a prospective, consecutive, nonrandomized clinical trial. Seventy-three eligible patients (109 eyes) received the implantation of echelette ERV IOL (Tecnis Symfony ZXR00) or diffractive bifocal IOL (Tecnis ZMB00). 1 week, 1 month, and 3 months after surgery, visual acuities at different distances were examined. At 3 months, defocus curves, contrast sensitivities (CSs) with and without glare, optic path difference (OPD) scans, and questionnaires were evaluated. Regression analyses were applied to discover influence factors on postoperative vision. Results ZXR00 showed better distance (P < 0.05) and intermediate (P < 0.001) visual acuities, while ZMB00 was better at distance-corrected near visual acuity (P < 0.001). Multivariate analyses indicated that worse intermediate (P < 0.001) and near vision (P=0.013) of ZMB00 might occur in patients with longer axial length. ZXR00 demonstrated smoother defocus curve and higher CSs. Superior modulation transfer function (MTF) and higher Strehl ratio (P < 0.05) were shown in ZXR00. In questionnaire evaluation, ZXR00 received better outcomes in self-reported vision, Visual Function-14 (VF-14) questionnaire, Quality of Vision (QoV) questionnaire, satisfaction, and recommendation grades. Spectacle dependence did not differ between ZXR00 and ZMB00 statistically. Conclusion ZXR00 proved to be remarkable in distance and intermediate vision, defocus curve smoothness, CSs, and visual comfort, while ZMB00 achieved better near vision. ZXR00 may attain better near vision if postoperative SE remains slightly negative. Patients with relatively longer axial length might receive less favorable intermediate and near vision after ZMB00 implantation. This trial is registered with ChiCTR-ONC-17011119.

Abstract
Purpose 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.

Abstract
Objective To compare the performance of adults with multifocal intraocular lenses (MIOLs) in a realistic flight simulator with age-matched adults with monofocal intraocular lenses (IOLs). Methods and Analysis Twenty-five adults ≥60 years with either bilateral MIOL or bilateral IOL implantation were enrolled. Visual function tests included visual acuity and contrast sensitivity under photopic and mesopic conditions, defocus curves and low luminance contrast sensitivity tests in the presence and absence of glare (Mesotest II), as well as halo size measurement using an app-based halometer (Aston halometer). Flight simulator performance was assessed in a fixed-based flight simulator (PS4.5). Subjects completed three simulated landing runs in both daytime and night-time conditions in a randomised order, including a series of visual tasks critical for safety. Results Of the 25 age-matched enrolled subjects, 13 had bilateral MIOLs and 12 had bilateral IOLs. Photopic and mesopic visual acuity or contrast sensitivity were not significantly different between the groups. Larger halo areas were seen in the MIOL group and Mesotest values were significantly worse in the MIOL group, both with and without glare. The defocus curves showed better uncorrected visual acuity at intermediate and near distances for the MIOL group. There were no significant differences regarding performance of the vision-related flight simulator tasks between both groups. Conclusions The performance of visually related flight simulator tasks was not significantly impaired in older adults with MIOLs compared with age-matched adults with monofocal IOLs. These findings suggest that MIOLs do not impair visual performance in a flight simulator.

Abstract
Purpose The purpose of this study was to compare the visual outcomes and subjective visual quality between bilateral implantation of a diffractive trifocal intraocular lens, Alcon Acrysof IQ® PanOptix® TNFT00 (group A), and blended implantation of an extended depth of focus lens, J&J Tecnis Symfony® ZXR00 with a diffractive bifocal intraocular lens, J&J Vision Tecnis® ZMB00 (group B). Methods This prospective, nonrandomized, consecutive, comparative study included the assessment of 40 eyes in 20 patients implanted with multifocal intraocular lens. Exclusion criteria were existence of any corneal, retina, or optic nerve disease, previous eye surgery, illiteracy, previous refractive surgery, high axial myopia, expected postoperative corneal astigmatism of >1.00 cylindrical diopter (D), and intraoperative or postoperative complications. Binocular visual acuity was tested in all cases. Ophthalmological evaluation included the measurement of uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), uncorrected near visual acuity (UNVA), and uncorrected intermediate visual acuity (UIVA), with the analysis of contrast sensitivity (CS), and visual defocus curve. Results Postoperative UDVA was 0.01 and −0.096 logMAR (p<0.01) in groups A and B, respectively; postoperative CDVA was −0.07 and −0.16 logMAR (p<0.01) in groups A and B, respectively; UIVA was 0.14 and 0.20 logMAR (p<0.01) in groups A and B, respectively; UNVA was −0.03 and 0.11 logMAR (p<0.01) in groups A and B, respectively. Under photopic conditions group B had better CS at low frequencies with and without glare. Conclusion Both groups promoted good quality of vision for long, intermediate, and short distances. Group B exhibited a better performance for very short distances and for intermediate and long distances ≥−1.50 D of vergence. Group A exhibited a better performance for UIVA at 60 cm and for UNVA at 40 cm.
