Abstract
PURPOSE To evaluate visual outcomes and patient-reported results after bilateral femtosecond-laser assisted refractive lens exchange (RLE) with the implantation of a diffractive trifocal intraocular lens (IOL). DESIGN Prospective interventional case series METHODS: A study of 27 patients (54 eyes) implanted with the Clareon PanOptix (Alcon) multifocal IOL during femtosecond laser assisted RLE in a university hospital setting. The uncorrected (UDVA) and corrected (CDVA) distance visual acuity, uncorrected (UIVA) and distance-corrected (DCIVA) intermediate visual acuity at 60cm, uncorrected (UNVA) and distance-corrected (DCNVA) near visual acuity at 40cm and 33cm were evaluated at three months postoperatively and compared with the preoperative values. In addition, we assessed the postoperative defocus curve, mesopic and photopic contrast sensitivity, and patient-reported spectacle independence. RESULTS The mean postoperative binocular UDVA was -0.02±0.06 logMAR and CDVA was -0.11±0.05 logMAR. The UIVA was -0.07±0.05 logMAR and DCIVA was -0.07±0.07 logMAR. The UNVA at 40cm was 0.03±0.09 logMAR and DCNVA was -0.02±0.06 logMAR; and, at 33cm UNVA was 0.14±0.10 logMAR and DCNVA was 0.11±0.08 logMAR. In comparison to the preoperative binocular CDVA (-0.12±0.08 logMAR), no statistically significant change was observed (p=1.0), while all the other binocular visual acuities improved (p<0.01). In the mean binocular defocus curve, the visual acuity was better than 0.10 logMAR in the range between +0.5 D and -3.0 D. The mean contrast sensitivity was within the normal range, and most patients reported complete spectacle independence. CONCLUSION The RLE surgery improved uncorrected visual acuity at far, intermediate and near distances without negatively affecting the CDVA. Patients achieved a high level of spectacle independence.

Abstract
PURPOSE To evaluate changes in cataract and refractive surgery practice patterns among members of the Japanese Society of Cataract and Refractive Surgery (JSCRS) over the past 20 years. STUDY DESIGN Questionnaire survey study. SUBJECTS AND METHODS Clinical surveys were conducted annually between February and April from 2004 to 2023. Survey questions covered various areas, including cataract surgical techniques, anesthesia, endophthalmitis prophylaxis, toric and presbyopia-correcting intraocular lenses (IOLs), complications, and refractive surgery. RESULTS The highest (n=554 [36.8%]) and lowest (n=316 [19.1%]) numbers of responses were collected in 2012 and 2016, respectively. In perioperative management, the intraoperative use of polyvinyl alcohol-iodine solution and topical antibiotic prescription 3 days before surgery has increased. The use of intracameral injection at the end of surgery has also significantly increased, although it has not been established as common practice. In anesthesia, there is a clear polarization between the use of topical drops and tenon injection. The use of toric IOLs and presbyopia-correcting IOLs has significantly increased from 2010 to 2023. In the latter, the use of trifocal IOLs has particularly increased. Regarding IOL power calculations, the Barrett True K and the Barrett Universal II formulas are rapidly gaining popularity for application with and without post-laser vision correction, respectively. In refractive surgery, phakic IOLs and corneal refractive therapy have attracted considerable interest, followed by laser in situ keratomileusis. CONCLUSIONS Evaluation of annual clinical survey data over the past two decades provided valuable insights into the shifting practice patterns and clinical opinions among JSCRS members.

Abstract
BACKGROUND In recent years intraocular lenses (IOLs) for correcting presbyopia have been significantly improved and diversified. There are currently many different IOL models based on a wide variety of optical designs. OBJECTIVE The wide variety of available IOL solutions to correct presbyopia can be challenging for surgeons and patients. In everyday practice, the question is which IOL is best for which patient. MATERIAL AND METHODS This overview describes and categorizes the currently available implants. The respective optical properties are analyzed and clinical study results are discussed, in particular those evaluating visual performance and the occurrence of photic phenomena. RESULTS Monofocal-plus IOLs provide improved intermediate visual acuity with optimal distant visual acuity and minimal photic phenomena. Extended depth of field (EDoF) IOLs extend the depth of field through different optical principles and provide good distant and intermediate visual acuity. Trifocal lenses enable the greatest independence from spectacles at the price of a higher probability of dysphotopsia. CONCLUSION The selection of the most suitable IOL for correction of presbyopia requires a balance between the patient's visual needs and possible side effects. An adequate knowledge of the currently available implants allows a patient-oriented selection of IOLs.

Abstract
Intraocular lenses (IOL) featuring complex optical designs can pose a challenge in understanding their performance, which may hinder making an informed decision when selecting suitable lenses for patients. This underlines the importance of collecting optical quality data of IOLs and making them available. The deployment of benchtop systems for IOL testing offers not only insights into the design features of various IOL solutions but also provides a platform for objective comparisons of special optics designs, including information about their susceptibility to photic phenomena. Recent advances in IOL testing have improved the ability to predict functional effects on visual acuity and contrast sensitivity from objective optical quality metrics. This, for instance, can be used to study monofocal lenses and the impact of asphericity on vision and IOLs tolerance to misalignment. Monofocal-plus IOLs consistently show only a slight improvement in the depth of focus when tested on the optical bench and in clinical settings. Although the pupil dependence found in this technology may limit the advantages of monofocal-plus over standard monofocal technology to extend the range of vision, it is the key to reduce photic phenomena. Refractive and diffractive extended depth of focus (EDOF) IOLs can effectively enhance intermediate vision, with the latter offering a slightly broader depth of focus but potentially increasing the risk of dysphotopsia. However, the limitation of EDOF IOLs is that they often fail to deliver spectacle independence for reading, which can be overcome by trifocal technology. Still, the available trifocal IOLs differ in their location of intermediate and near foci and the susceptibility to produce glare effects. Therefore, the knowledge from optical benchtop testing of IOLs can support optimizing the IOL selection by aligning the patient's visual needs with the IOL's properties, setting the right expectations, and assessing the risk profile for the occurrence of photic phenomena, potentially leading to improved decision-making.

Abstract
PURPOSE To evaluate the clinical outcomes of the toric version of a presbyopia-correcting intraocular lens (IOL) based on the combination of a diffractive-based extended depth-of-focus (EDOF) pattern and a diffractive multifocal platform. SETTING Miranza COI Bilbao, Bilbao, Spain. DESIGN Prospective case series. METHODS 35 patients (51 to 84 years) with corneal astigmatism ranging from 0.75 to 2.19 diopters (D) undergoing bilateral cataract surgery with implantation of the Synergy Toric II IOL were evaluated during a 3-month follow-up. Visual acuity, refraction, defocus curve, and patient-reported outcomes with the Catquest-9SF questionnaire were analyzed. A vectorial analysis was used to analyze the accuracy of astigmatic correction. RESULTS Mean 3-month monocular postoperative uncorrected distance, intermediate (80 cm) and near (40 cm) visual acuities were 0.06 ± 0.11 logMAR, 0.13 ± 0.12 logMAR, and 0.13 ± 0.09 logMAR, respectively. Mean monocular distance-corrected intermediate (80 cm) and near visual acuity (40 cm) were 0.11 ± 0.12 logMAR and 0.10 ± 0.10 logMAR, respectively. Mean binocular defocus curve showed visual acuities of 0.10 logMAR or better for defocus levels from +0.50 to -2.50 D. Residual cylinder was within ±0.50 D in 97.0% of eyes. The surgically induced astigmatism prediction error ranged between -0.49 D and 0.50 D, with a mean value of 0.04 ± 0.16 D. Mean absolute IOL rotation was 3.79 ± 2.94 degrees. Significant improvements were found in all Rasch-calibrated scores obtained with Catquest-9SF ( P < .001). CONCLUSIONS The implantation of the toric presbyopia-correcting IOL evaluated provides an efficacious astigmatic correction while providing a fully restoration of the visual function across different distances.

Abstract
PURPOSE To assess long-term clinical results following bilateral Tecnis Symfony ZXR00 intraocular lens implantation with mini-monovision. METHODS The medical records of cataract patients who underwent bilateral implantation of ZXR00 with intended mini-monovision (target refraction of -0.3 diopters [D] in dominant eye and -0.6 D in nondominant eye) between April 2019 and March 2021 were assessed. Postoperative uncorrected distance visual acuity (UDVA), corrected distance VA (CDVA), uncorrected intermediate VA (UIVA), uncorrected near VA (UNVA), and rate of spectacle dependence for near distance were investigated at 3 months and 2 years after surgery. RESULTS This study included 61 patients (122 eyes) with average age of 61.8 ± 7.7 years. At 2 years postoperatively, binocular logarithm of the minimum angle of resolution UDVA, UIVA, UNVA, and CDVA were 0.086 ± 0.094, 0.056 ± 0.041, 0.140 ± 0.045, and 0.012 ± 0.024, respectively. The monocular manifest refraction spherical equivalent was -0.31 ± 0.38 in the dominant eye and -0.53 ± 0.47 in the nondominant eye at 3 months postoperatively, and -0.38 ± 0.43 in the dominant eye and -0.61 ± 0.54 in the nondominant eye at 2 years postoperatively. Eight out of 61 patients (13.1%) needed glasses 3 months after surgery, and nine out of 61 patients (14.8%) needed glasses 2 years after surgery. CONCLUSIONS The bilateral implantation of ZXR00s with mini-monovision allows for a good VA at wide range of distance from far to near, thereby resulting in high rate of spectacle independence. These results have held up well even after 2 years after surgery.

Abstract
PURPOSE To compare clinical outcomes after implantation of TECNIS Synergy (ZFR00V) intraocular lenses (IOLs) in both eyes and implantation of the TECNIS Synergy and TECNIS Eyhance (ICB00) combination in patients undergoing cataract surgery. SETTING Department of Cataract, Hospital Oftalmológico de Brasilia (HOB), Brasília, Brazil. DESIGN Prospective, interventional, randomized, parallel-group study. METHODS Patients were categorized into 2 groups: Group 1: ZFR00V IOL was implanted in both eyes. Group 2: An ICB00 IOL was implanted in the dominant eye, and a ZFR00V IOL was implanted in the nondominant eye. RESULTS Visual acuity was similar between the 2 groups (95% CI <0.1 logMAR). A superior visual acuity of ≥ 20/25 (at -2.00 to -2.50 diopters [D]) was achieved in Group 1 (bilateral ZFR00V) than in Group 2 (combination of ZFR00V/ICB00). The binocular defocus curve demonstrated better visual acuity at 40 cm (-2.00 D) and 50 cm (-2.50 D) in Group 1 than in Group 2 ( P < .05). Similar contrast sensitivity values were observed between the 2 groups. Patients in Group 1 reported higher satisfaction (completely satisfied) than those in Group 2 ( P < .05). However, halos and glare were more pronounced in Group 1 than in Group 2 ( P < .05). CONCLUSIONS Both presbyopia-correcting IOL combinations showed similar binocular visual acuity results. Group 1 demonstrated enhanced visual acuity in the defocus curve at 40 cm (-2.00 D) and 50 cm (-2.50 D). Comparable contrast sensitivity outcomes were observed in both groups. Patients were more completely satisfied in Group 1 than in Group 2, despite the higher frequency of postoperative nighttime halos and glare.

Abstract
INTRODUCTION To evaluate and compare the clinical outcomes of two toric presbyopia-correcting intraocular lenses (IOLs). METHODS Non-randomized prospective comparative study including 86 eyes of 51 patients (age 43-83 years) that underwent cataract surgery with implantation of one of the following two IOLs: TECNIS Toric Synergy (Johnson & Johnson Vision) (Synergy group) or AT LISA tri toric 939MP (Carl Zeiss Meditec) (ATLISA group). Visual and refractive outcomes were evaluated during a 6-month follow-up. RESULTS At 6 months after surgery, all eyes achieved uncorrected distance visual acuity 20/25 or better in both groups, whereas 96.2% and 100% of eyes achieved uncorrected near visual acuity (UNVA) 20/25 or better in the ATLISA and Synergy groups, respectively. All eyes achieved postoperative mesopic UNVA 20/30 or better in both IOL groups; 96.2% and 100% of eyes had a manifest cylinder ≤ 0.50 D at 6 months in ATLISA and Synergy groups, respectively. Mean magnitude of error was 0.04 ± 0.20 and - 0.04 ± 0.09 D in ATLISA and Synergy groups, respectively (p = 0.05). In the defocus curve, significant differences were found between IOL groups for most of distance-corrected visual acuities, except those corresponding to defocus of 0 D (p = 0.268) and - 1 D (p = 0.361). CONCLUSIONS The two toric presbyopia-correcting IOLs evaluated provide an efficacious astigmatic correction combined with a successful distance, intermediate and near visual rehabilitation. The visual performance seems to be better for most visual demands with the TECNIS Toric Synergy IOL, especially for distances closer than 40 cm.

Abstract
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.

Abstract
PURPOSE To clinically evaluate a diffractive continuous-range-of-vision intraocular lens (IOL) that combines bifocal and extended depth-of-focus technologies in refractive lens exchange (RLE) patients. SETTING University eye clinic. DESIGN Prospective interventional clinical study. METHODS Bilateral implantation of the TECNIS Synergy IOL was performed during a RLE procedure in 28 patients. At 3 months postoperatively, uncorrected (UDVA) and corrected (CDVA) distance visual acuities, uncorrected (UIVA) and distance-corrected (DCIVA) intermediate visual acuities at 80 cm, and uncorrected (UNVA) and distance-corrected (DCNVA) near visual acuities at 40 cm were assessed. Defocus curve testing and contrast sensitivity testing were also performed. RESULTS Binocular UDVA and CDVA of 56 eyes (28 patients) were -0.06 ± 0.07 logMAR and -0.13 ± 0.05 logMAR, respectively. UIVA and DCIVA were -0.06 ± 0.05 logMAR and -0.08 ± 0.06 logMAR, and UNVA and DCNVA were -0.01 ± 0.07 logMAR and -0.04 ± 0.07 logMAR. The defocus curve revealed a visual acuity of 0.10 logMAR or better from +0.50 to -3.00 diopters (D). Photopic contrast sensitivity at spatial frequencies 3.0, 6.0, 12.0, and 18.0 was 1.68 ± 0.20, 1.77 ± 0.19, 1.45 ± 0.18, and 1.02 ± 0.19 log units, respectively. Mesopic contrast sensitivity at the same frequencies was 1.56 ± 0.20, 1.44 ± 0.25, 0.92 ± 0.38, and 0.44 ± 0.37, respectively. CONCLUSIONS The Synergy IOL provided very good distance, intermediate, and near visual outcomes. A visual acuity of 0.10 logMAR or better was achieved from +0.50 to -3.0 D. Contrast sensitivity was within the normal range.

Abstract
This study compared the optical quality and chromatic performance of refractive-diffractive intraocular lenses (IOLs) that are designed to extend the range of vision of pseudophakic patients and alter chromatic aberration. Five IOLs were evaluated, Tecnis Synergy and Triumf POD L GF, both intended to compensate for eye's chromatism, as well as Acriva Trinova Pro C-a lens that increases chromatic aberration, and AT Lisa Tri and AcrySof IQ PanOptix. An optical setup composed of a corneal model inducing monochromatic and chromatic aberrations and incorporating various spectral conditions was employed. The two chromatic-aberration correcting IOLs demonstrated the lowest far-focus dispersion, but it was negative only, with the Synergy indicating its ability to reduce eye's chromatic aberration. Although the Trinova increased far-point chromatism, it was close to the level of the PanOptix, but higher than that of the AT Lisa. All the studied models demonstrated varying optical quality in response to light color. Still, the strongest spectral dependency was associated with achromatizing technology. Therefore, chromatic aberration and wavelength dependency should be considered in IOL optimization and predicting visual function, particularly in non-white spectral conditions.

Abstract
Simultaneous implantation of a monofocal or monofocal toric intraocular lens (IOL) into the capsular bag and a multifocal IOL into the ciliary sulcus, referred to as duet procedure, allows us to create multifocality that is more easily reversible than the implantation of a capsular bag-fixated multifocal IOL. The optical quality and results after the duet procedure are equivalent to those of a capsular bag-fixated multifocal IOL. Patients who cannot tolerate the side effects of multifocal optics or who develop an ocular condition leading to loss of function such as age-related macular degeneration (AMD) or glaucoma in the course of their lives may benefit from the reversibility of the procedure.

Abstract
Presbyopia correction through implantation of a trifocal intraocular lens (IOL) is a modality offered to both cataract and refractive-lens exchange patients. To maximize postoperative satisfaction, IOL selection needs to be made based on patients’ requirements aligned with the available technology. Five Trifocal IOLs were assessed in this study, and their differentiating features were identified: Triumf POD L GF, AT Lisa Tri, Tecnis Synergy, AcrySof IQ PanOptix, and Acriva Trinova Pro C. The optical quality was assessed using the modulation-transfer-function principle. Simulated defocus curves were derived from a non-linear formula. Far-focus simulated visual acuity (simVA) was 0.03 logMAR or better for all the studied IOLs, showing minimal differences. However, each IOL’s intermediate focus position differed across a range from 61 cm to 80 cm; and for the near focus, it was 36 cm to 44 cm. Triumf demonstrated improved intermediate point at the expense of the near focus resulting in a lower predicted near VA. PanOptix exhibited the shortest range of vision without a clear distinction between intermediate and near-point. The remaining lenses presented three foci of comparable optical quality and, thus, simVA performance. Each model, however, revealed a different aperture-change response. Trinova function improved at intermediate but was worse at near for larger pupils. The opposite was observed for AT Lisa. Synergy’s optical quality change was predominantly associated with lower pupil diameter. In conclusion, the trifocal IOLs can be differentiated according to their secondary-foci position, light-energy distribution, and pupil-size-related behavior. The observed differences may translate directly into a clinical effect showing that the trifocal IOLs vary in their ability to deliver optimal vision at different distances, with some providing improved intermediate while others favor reading distance. The knowledge gained through this objective testing can support IOL selection, postoperative patient counselling and increase the chance of spectacle independence after surgery.
