Abstract
PURPOSE To evaluate the vision recovery, reconstruction of binocular visual function, and influencing factors after multifocal intraocular lens implantation in children with unilateral congenital cataracts. SETTING University hospital. DESIGN Prospective clinical study. METHODS In the prospective clinical study, 55 children aged 3 to 14 with unilateral congenital cataracts received multifocal intraocular lenses (TECNIS ZMB00) posterior optic capture from 2019 to 2022. Corrected distance visual acuity (CDVA; 5 m), distance-corrected intermediate visual acuity (DCIVA; 66 cm), distance-corrected near visual acuity (DCNVA; 33 cm), stereoscopic vision, visual quality (objective scatter index [OSI] and modulation transfer function [MTF]), axial length (AL), keratometry (K), and contrast sensitivity (CS), as well as postoperative occlusion compliance were evaluated before and after surgery. RESULTS At the final follow-up, 90.91% (50/55) patients showed significant improvement in visual acuity (VA) after surgery. CDVA, DCIVA and DCNVA were 0.23 ± 0.17, 0.39 ± 0.15, and 0.44 ± 0.15 logMAR, respectively. 69.09% (38/55) patients achieved good VA (better than 0.3 logMAR).52.76% (25/48) patients had a positive Titmus test. OSI and MTF were 1.24 ± 0.91 and 42.45 ± 12.30, respectively. 73.68% (28/38) of the patients (better than 0.3 logMAR) underwent strict occlusion therapy. Postoperative VA is correlated with preoperative CDVA ( r = -0.829, P < .001), corneal astigmatism ( r = 0.384, P = .036), △AL (difference between the cataract eyes and contralateral eyes, r = -0.490, P = .006), and occlusion compliance ( r = -0.806, P < .001). CONCLUSIONS Multifocal intraocular lens implantation could obtain relatively satisfactory VA (CDVA, DCIVA and DCNVA) and the binocular visual function of children with unilateral congenital cataracts. Postoperative VA is related to preoperative VA, corneal astigmatism, △AL, and occlusion compliance.

Abstract
PURPOSE To compare visual outcomes and satisfaction in patients with emmetropia, presbyopia, and greater or lesser residual accommodation who undergo unilateral or bilateral implantation of a trifocal diffractive intraocular lens (IOL). METHODS A multicenter, multisurgeon study was performed to evaluate outcomes in patients with emmetropia and presbyopia who underwent refractive lens exchange followed by implantation of a FineVision trifocal IOL (PhysIOL). The inclusion criteria were as follows: emmetropia, sphere -0.25 to +0.50 diopters (D), cylinder less than 0.75 D, and manifest refractive spherical equivalent (MRSE) of -0.25 to +0.25 D. All patients also had to have an uncorrected distance visual acuity (UDVA) of Snellen 0.9 or better in each eye. The sample was divided into different clusters based on two variables: eyes operated on (monocular or binocular) and age either younger than 55 years or 55 years or older. Thus, four possible groups were created. Visual and refractive performance, patient satisfaction, and spectacle independence were assessed. RESULTS A total of 690 eyes from 431 patients were evaluated. There was no difference in postoperative uncorrected (UDVA) and corrected (CDVA) distance visual acuity between the groups. Binocular uncorrected near vision (UNVA) was better in patients who underwent surgery on both eyes regardless of age (median [interquartile range]: 0.00 [0.00; 0.10] vs 0.10 [0.00; 0.10] logMAR; P < .001). Binocular uncorrected intermediate vision (UIVA) was better in patients who underwent surgery on both eyes aged younger than 55 years than in those who underwent surgery in one eye aged 55 years or older (median [interquartile range]: 0.18 [0.10; 0.18] vs 0.30 [0.18; 0.30] logMAR; P < .001). The efficacy and safety indexes were 0.98 ± 0.09 and 1.01 ± 0.06, respectively. A total of 93.3% of eyes were within the 0.50 D range in postoperative MRSE. Visual dysphotopsia was worse in patients with both eyes operated on, although the differences were not statistically significant. CONCLUSIONS The study shows that after refractive lens exchange, patients with emmetropia and presbyopia who received a trifocal IOL in one or both eyes achieved good UNVA, UIVA, and UDVA. Regarding near binocular visual acuity, results were better for patients who underwent surgery on both eyes than for those who underwent surgery on one eye. Regarding binocular intermediate visual acuity, patients aged younger than 55 years with both lenses replaced had better results than those 55 years or older with only one lens replaced. However, no significant differences were observed in UDVA or patient satisfaction. [J Refract Surg. 2023;39(12):817-824.].

Abstract
PURPOSE To determine the cut-off points for age and metrics provided by cataract grading objective systems for which a reestablishment in contrast sensitivity (CS) is expected after multifocal intraocular lens (MIOL) implantation. METHODS One hundred seven subjects were included in this retrospective analysis carried out during the screening for presbyopia and cataract surgery. Monocular distance corrected contrast sensitivity defocus curve (CSDC) and visual acuity were measured, and crystalline lens sclerosis was graded with three objective metrics: Ocular Scatter Index (OSI), Dysfunctional Lens Index (DLI) and Pentacam Nucleus Staging (PNS). A CS value of 0.8 logCS at far distance, following published literature on this matter, was selected to compute the cut-off that maximized the detection of eyes exceeding this value at the preoperative screening, either for age or objective metrics. RESULTS The CDCS showed a stronger correlation than CDVA with objective grading methods, whereas all objective metrics were significantly correlated between them (p < 0.05). The cut-offs for age, OSI, DLI and PNS were ≤ 62, ≤ 1.25, ≥ 7.67 and ≤ 1, respectively. The OSI provided the highest area under the receiver operating characteristic curve (0.85) followed by the age (0.84), DLI (0.74) and PNS (0.63). CONCLUSIONS Surgeons conducting clear lens exchange should communicate the possible distance CS loss after surgery with MIOL implantation according to the previous described cut-offs points. Age in combination with any cataract grading objective system is recommended to detect possible inconsistencies.

Abstract
PURPOSE To determine the visual and refractive outcomes of trifocal toric intraocular lens (IOL) implantation in Asian eyes with cataract and astigmatism. SETTING Asian Eye Institute, Makati City, Philippines. DESIGN Prospective study. METHODS 187 eyes were implanted with the FineVision POD FT IOL and followed for 2 years. The measurements included subjective refraction, uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), uncorrected intermediate visual acuity (UIVA), distance-corrected intermediate visual acuity (DCIVA), uncorrected near visual acuity (UNVA), distance-corrected near visual acuity (DCNVA), defocus curve, photopic and mesopic contrast sensitivity, and rotational stability. RESULTS The mean spherical equivalent and cylinder values were, respectively, -0.07 ± 0.34 diopters (D) and -0.48 ± 0.31 D at the 2-year follow-up. At this same follow-up, 69.4% of patients had monocular CDVA and 79.3% had binocular UDVA ≤0.0 logMAR. For intermediate vision, monocular DCIVA reached 74.1%, while binocular UIVA was 86.2% ≤ 0.1 logMAR. Near vision showed 63% for monocular DCNVA and 70.7% for binocular UNVA ≤0.1 logMAR. The mean values at this follow-up were 0.02 ± 0.08, 0.08 ± 0.10, and 0.10 ± 0.12 logMAR for CDVA, DCIVA, and DCNVA, respectively. At the visual acuity threshold of ≤0.20 logMAR, the binocular defocus curve extended up to -3.75 D. Stable contrast sensitivity values were obtained at the different follow-ups. The mean IOL rotation was ≤2 degrees. CONCLUSIONS The FineVision POD FT IOL yielded good visual outcomes at far, near, and intermediate distances with accurate refractive outcomes and good rotational stability in Asian eyes.

Abstract
Purpose To assess contrast sensitivity and patient reported outcomes after uncomplicated cataract surgery with a new bi-aspheric diffractive trifocal intraocular lens (IOL) implantation. Methods Twenty-five patients who underwent bilateral implantation with the Asqelio Trifocal TFLIO130C IOL (AST Products Inc., Billerica, MA, USA) were analyzed at 6 months post-surgery. Binocular contrast sensitivity with and without glare was measured under photopic conditions (85 cd/m2) and mesopic conditions (3 cd/m2). Patients were asked to complete the Catquest-9SF patient outcomes questionnaire and a visual symptoms questionnaire. Results Photopic contrast sensitivity values were either within or above normal levels without glare; when glare was induced, the mean sensitivity values dropped just below normal range. Mesopic contrast sensitivity values were above or within normal range both with and without glare, except for 12 cpd with glare, where the mean fell just below the normal range. Differences in binocular contrast sensitivity threshold values with and without glare were significant for all spatial frequencies tested under both photopic and mesopic conditions (p<0.05). The Catquest-9SF questionnaire outcomes showed that 88% of patients were either satisfied or very satisfied with their sight after the surgery, and in all cases, the results indicated no difficulty in performing different daily activities. The visual symptoms questionnaire indicated no relevant visual symptoms regarding frequency, intensity, or bothersomeness after implantation of the trifocal IOL. Conclusion This novel bi-aspheric diffractive trifocal IOL provides good contrast sensitivity outcomes under bright and dim lighting conditions. Patients were satisfied with the surgery, with no relevant visual symptoms.

Graefes Arch Clin Exp Ophthalmol 2022; 260:2753-2762. [PMID: 35175409 PMCID: PMC9325843 DOI: 10.1007/s00417-022-05584-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/07/2020] [Revised: 01/04/2022] [Accepted: 02/01/2022] [Indexed: 11/27/2022] Open
Abstract
Purpose To assess the results of partial monovision (PMV) in comparison to a bilateral monofocal implantation (MMV). Methods The PMV group was treated bilaterally with a monofocal intraocular lens (IOL) implantation, followed 3 months later by the implantation of a multifocal AddOn® lens (+ 3.00 D) into the non-dominant eye. The MMV group received a bilateral monofocal IOL implantation intending to achieve a slight anisometropia (0.0 D/ − 0.50 D). The near visual acuity (UNVA), intermediate visual acuity (UIVA), distance visual acuity (UDVA), defocus curve, and Lang-Stereotest II were conducted uncorrected, binocular, and minimum 3 months after the last operation. For the contrast sensitivity test, the patients were refractively corrected. The Quality of Vision Questionnaire (QoV), Visual Function Questionnaire (VF-14), spectacle independence, and general satisfaction were also assessed. Results A total of 27 PMV patients and 28 MMV patients without ocular diseases relevant to visual acuity were examined. The PMV group was significantly better at UNVA (0.11 ± 0.08 logMAR vs 0.56 ± 0.16 logMAR) and between − 2.00 and − 4.00 D in the defocus curve (p < 0.001). At the UIVA, the PMV group was slightly better (0.11 ± 0.10 logMAR vs 0.20 ± 0.18 logMAR) but not significant (p = 0.054). The UDVA (− 0.13 ± 0.09 logMAR vs − 0.09 ± 0.14 logMAR) (p = 0.315) and contrast sensitivity (p = 0.667) revealed no differences between the groups. The stereo vision was in favor of PMV (p = 0.008). Spectacle independence was statistically better for PMV at distance, intermediate, and near (distance p = 0.012; intermediate p < 0.001; near p < 0.001). In the VF-14 Questionnaire, the PMV was statistically superior (p < 0.001). The QoV Questionnaire showed no differences regarding frequency and severity of visual disturbances. Both groups were highly satisfied (p = 0.509). Conclusion Patients with PMV are more independent of glasses and are able to read without disadvantages in distance vision, due to halos and glare. The concept of PMV is well suited for the desire of eyeglass independence, without optical side effects.

Abstract
PURPOSE To evaluate binocular visual function after unilateral and bilateral implantation of segmented refractive multifocal intraocular lenses (MIOLs). METHODS This prospective comparative pilot study included patients who underwent SBL-3 (Lenstec; + 3.00 D) implantation at Peking University Third Hospital. Patients were divided into two groups (monocular or binocular surgery). Thirty-two patients with emmetropic presbyopic contralateral eyes and 49 patients with bilateral SBL-3 implantation within a week between eyes were included in the unilateral SBL-3 and bilateral groups, respectively. At 3-month follow-up, the main outcomes were binocular uncorrected distant, intermediate, and near visual acuity (UDVA, UIVA, and UNVA). Secondary outcomes included binocular best-corrected visual acuity at all distances, defocus curve, contrast sensitivity, photic phenomena, spectacle independence, patient satisfaction, and National Eye Institute Visual Function Questionnaire (NEI-VFQ-25) score. The essential perceptual phenomena constituting binocular vision, simultaneous perception, fusion, and stereopsis were also evaluated. RESULTS Both groups showed similar binocular UDVA and UIVA, but UNVA was significantly better in the bilateral group (0.07 ± 0.07 versus 0.12 ± 0.07, P = 0.008). Better binocular defocus curve at intermediate to near focal points, higher percentage of spectacle independence at near distance, and NEI-VFQ-25 near activity scores were observed in the bilateral group. No significant differences in contrast sensitivity, photic phenomena, overall satisfaction, other NEI-VFQ-25 subscales, fusional amplitude, and stereoacuity were found between groups. CONCLUSION Unilateral implantation of segmented refractive MIOL provided desirable distant visual acuity and high patient satisfaction, but inferior intermediate and near visual outcomes compared with bilateral implantation.

Abstract
Presbyopia is a common age-related vision disorder characterized by a progressive inability to focus on near objects. If uncorrected or under-corrected, presbyopia can significantly impact patients' quality of life. Presbyopia represents an area of considerable unmet need due to its rising prevalence worldwide as the population ages, the high proportion of under-treated individuals in some parts of the world, and the limitations of currently available corrective methods. Progressive or bifocal spectacles are associated with peripheral blur, a restricted visual field and impaired depth perception, which have been linked to an increased risk of falls in the elderly. Contact lens options can be difficult to maintain due to the development of age-related dry eye symptoms and reduced manual dexterity. Other corrective methods involve surgical interventions that modify the optics of the cornea, replace the crystalline lens, or attempt to restore active accommodation. While patients undergoing surgery report satisfactory outcomes post-operatively, many of them eventually require reading glasses. Non-invasive therapies with novel mechanisms of action are currently being investigated; these include miotic agents and UNR844, a lipoic acid choline ester. In this narrative review, available evidence on presbyopia prevalence, quality of life impact and risk factors are described, with a focus on observational studies in non-clinical settings. The diagnosis pathway and patient journey in presbyopia are outlined, and various treatment options are analyzed. The data reviewed herein reveals significant gaps in the provision of vision correction for this common condition, with a paucity of effective, non-invasive treatment options broadly accessible to presbyopic individuals.

Abstract
PURPOSE To compare visual outcomes and patient satisfaction between unilateral and bilateral trifocal diffractive intraocular lens (IOL) implantation in emmetropic patients with presbyopia. DESIGN Retrospective observational case series. METHODS This is a multicenter, multisurgeon study of emmetropic presbyopes who underwent refractive lens exchange (RLE) followed by an implantation of FineVision IOL (PhysIOL). Inclusion criteria were emmetropic eyes, with a sphere between -0.25 and +0.50 diopters (D), cylinder of less than 0.75 D and spherical equivalent (SE) between -0.25 and +0.25 D. In addition, uncorrected distance visual acuity (UDVA) had to be Snellen >0.9 in each eye. A total of 171 eyes of 122 patients were evaluated. This sample was divided into 2 groups depending on whether they have been operated monocularly or binocularly. Visual and refractive performance, patient satisfaction, and spectacle independence were evaluated. RESULTS UDVA and corrected distance visual acuity (CDVA) remained almost unchanged after monocular and binocular surgery. Binocular uncorrected intermediate (UIVA) and near visual acuity (UNVA) were better in those operated binocularly (0.3±0.12 vs 0.22±0.06, P < .063, and 0.09±0.08 vs 0.04±0.05, P < .027, respectively). Predictability and efficacy were higher in the binocular group, whereas safety was better in the monocular group. Visual dysphotopsia was worse and spectacle independence for all distances was higher in binocular group. CONCLUSIONS Our research shows that RLE with binocular implantation of a trifocal diffractive IOL in presbyopic emmetropic patients is more successful in UNVA than monocular implantation. However, no significant differences were observed in UDVA, UIVA, and patient satisfaction.

Abstract
Purpose To study the patients’ perception of trifocal IOL (Panoptix™) performance. Patients and methods 60 eyes of 35 were implanted with trifocal IOL. Refractive (sphere – S, cylinder – Cyl and spherical equivalent – SE, all in D) and visual (distance uncorrected – VAsc, distance corrected – VAcc, intermediate – IntVA, near uncorrected – NVAsc and distance corrected near – NVAcc, all in LogMAR) results were recorded. Patients were asked about satisfaction (per eye), spectacle independence, near and intermediate activities, distance activities in quantity and quality, finally about personal facial care (per patient). Comparison was made between non-toric (48) and toric models, genders (18 males) and between bilateral (25 patients) and unilateral implantations. Results were correlated to age and IOL power. Results With a SE of mean −0.3 ± 0.5 D, cases achieved mean VAsc 0.09 ± 0.1 (~20/25), VAcc 0.05 ± 0.1 (~20/22), IntVA 0.05 ± 0.9 (~20/22), NVAsc 0.05 ± 0.09 (~~20/22) and NVAcc 0.04 ± 0.8 (~~20/22). Mean level of satisfaction was 85.7 ± 16.5, spectacle independence 96.0 ± 10.6, near activities 95.4 ± 9.8, intermediate activities 97.7 ± 6.4, quantity of distance activities 90.2 ± 10.1, quality of distance activities 88.0 ± 12.1 and facial care 92.6 ± 11.9. All comparisons (non-toric and toric, male and female and bilateral and unilateral implantation) were statistically insignificant (P>0.05). Correlation with age and IOL power was also statistically insignificant (P>0.05). Conclusion As perceived by patients, trifocal IOL resulted in very high level of satisfaction. This satisfaction is reflected on diverse visual activities. This level is achieved regardless of gender, IOL model or even unilateral implantation. It is also achieved regardless the age of patients or preoperative eye status.
