Abstract Purpose To evaluate the clinical outcomes and visual quality of patients undergoing cataract surgery with the implantation of two different models of diffractive trifocal intraocular lenses (IOLs).MethodsThis randomized prospective comparative study included 60 eyes of 15 patients who scheduled to undergo bilateral cataract surgery with the implantation of two models of diffractive trifocal IOLs (RayOne Trifocal and AcrySof IQ PanOptix IOL). Monocular and binocular corrected and uncorrected distance visual acuity (CDVA, UDVA), intermediate visual acuity (DCIVA, UIVA) at 60 and 80 cm, near visual acuity (DCNVA, UNVA), and patient satisfaction were compared over a three-month follow-up.ResultsEach group comprised 30 eyes of 15 patients. No statistically significant differences were determined between the groups in terms of CDVA, UDVA, DCNVA and UNVA. The monocular and binocular UIVA values at 60 cm were better in the PanOptix IOL group (p=0.04 and p=0.01, respectively), and the DCIVA and UIVA values at 80 cm were better in the RayOne IOL group (p=0.01, p=0.047, p<0.001, and p=0.042, respectively). No statistically significant difference was found between the groups in relation to the frequency and severity of visual symptoms evaluated. Regarding discomfort, the RayOne IOL group had more bothersome halos and starbursts (p=0.026 and p=0.01, respectively).ConclusionBoth IOLs provided very good restoration of visual acuity. However, with the AcrySof IQ PanOptix IOL, the likelihood of patients experiencing bothersome halos and starbursts was less. The RayOne Trifocal IOL might be a better choice for patients who require further intermediate vision.The study was registered under the World Health Organization international clinical trials registry platform: NCT04655274, 30/11/2020, prospectively registered.

Abstract Background：To compare the clinical performance of bifocal and trifocal intraocular lenses (IOLs) in cataract surgery, a meta-analysis on randomized controlled trials was conducted. Methods: A comprehensive literature retrieval of PubMed, Science Direct and EMBASE was performed in this systematic review. Clinical outcomes included visual acuity (VA), contrast sensitivity (CS), spectacle independence, postoperative refraction and surgical satisfaction. Results: There were 8 RCTs included in this study. The difference of uncorrected near VA (UNVA) between the bifocal IOLs and trifocal IOLs had no clinical significance [MD=-0.01, 95%CI: (-0.02,0.00)]. There was no significant difference in the distant-corrected near VA (DCNVA) with MD of 0.04 [95%CI (-0.02, 0.10)]. Compared with trifocal group, the uncorrected intermediate visual acuity (UIVA) [MD=0.09,95%CI:(0.01,0.17)] was significantly worse in the bifocal group. No difference was found in distance-corrected intermediate VA(DCIVA) [MD= 0.09, 95%CI: (-0.04, 0.23)] between two groups. Analysis on AT LISA subgroup indicated the bifocal group had worse intermediate VA than trifocal group (AT LISA tri 839M) [MD= 0.18, 95%CI: (0.12, 0.24) for UIVA and MD= 0.19, 95%CI: (0.13, 0.25) for DCIVA]. However, there was no statistically significant difference between the two groups in the uncorrected distance VA(UDVA) and corrected distance visual acuity (CDVA) [MD=0.01, 95%CI: (-0.01,0.04) for UDVA; MD=0.00, 95%CI: (-0.01,0.01) for CDVA]. The postoperative refraction of bifocal group was similar to that of trifocal group [MD=-0.08, 95% CI: (-0.19, 0.03) for spherical equivalent; MD=-0.09, 95%CI: (-0.21, 0.03) for cylinder; MD=-0.09, 95% CI: (-0.27, 0.08) for sphere]. No difference was found for spectacle independence, posterior capsular opacification (PCO) incidence and patient satisfaction between bifocal IOLs and trifocal IOLs. [RR=0.89, 95% CI: (0.71, 1.12) for spectacle independence; RR=1.81, 95% CI: (0.50, 6.54) for PCO incidence; RR=0.98, 5% CI: (0.86, 1.12) for patient satisfaction]. Conclusion: Patients receiving trifocal IOLs, especially AT LISA tri 839M, have a better intermediate VA than those receiving bifocal IOLs. Near and distance visual performance, spectacle independence, postoperative refraction and surgical satisfaction of bifocal IOLs were similar to those of trifocal IOLs.

Purpose. To evaluate the clinical outcomes after bilateral mix-and-match cataract surgery using extended depth of focus (EDOF) and diffractive multifocal (DMF) intraocular lenses (IOLs). Setting. Asan Medical Center, Seoul, South Korea. Design. Prospective clinical study. Methods. Thirty-seven patients underwent TECNIS Symfony EDOF IOL (ZXR00) implantation in the dominant eye, and TECNIS +3.25 DMF IOL (ZLB00) implantation in the nondominant eye. Patients were followed up for 3 months; uncorrected and corrected distance visual acuity (UDVA and CDVA), uncorrected intermediate and near visual acuity (UIVA and UNVA), contrast sensitivity, defocus curves, stereopsis, and patient satisfaction were assessed. Results. At 3 months, the mean logarithm of the minimum angle of resolution (logMAR) of UDVA was 0.07 ± 0.09 in EDOF IOL eyes, 0.12 ± 0.11 in DMF IOL eyes, and 0.02 ± 0.05 in both eyes. UIVA was 0.11 ± 0.11 in EDOF IOL eyes, 0.16 ± 0.12 in DMF IOL eyes, and 0.04 ± 0.07 in both eyes. UNVA was 0.25 ± 0.15 in EDOF IOL eyes, 0.22 ± 0.16 in DMF IOL eyes, and 0.13 ± 0.13 in both eyes. Thirty patients (81.1%) were more than satisfied with near vision, and 8 patients (21.6%) complained of severe glare and halo. Spectacle independence for near vision was achieved in 34 patients (91.9%), and 31 patients (83.8%) had better than a 50-second arc of stereopsis. Conclusion. Mix-and-match cataract surgery with EDOF and DMF IOL implantation provided good visual outcomes for all distances. Additionally, excellent patient satisfaction was achieved with a high level of spectacle independence and acceptable photic phenomena.

Aim. The aim of the study is to examine changes in the anthropometric and refractive parameters of the eyeball in children with congenital cataracts who have been implanted with various types of IOLs (toric or classic monofocal). Materials and methods. In this work, we retrospectively studied the medical history of 34 children (42 eyes) aged 4 to 15 years, who underwent phacoemulsification of congenital cataracts with implantation of various types of IOLs: toric and simple monofocal. Further, in these groups, by statistical methods, the dynamics of refraction in the first three years after the operation, the incidence of postoperative astigmatism, and its dynamics were assessed. We also assessed the rate of change in the anteroposterior axis of the eyeball, the dynamics of refraction in terms of the total spheroequivalent and maximum visual acuity in 3 years after the operation. Results. According to the results of the study, it was shown that toric IOLs significantly better stimulate the process of emmetropization of the eyeball, and also have a significant tendency to completely eliminate postoperative astigmatism, within 3 years after surgery. However, there were no significant differences in maximally corrected visual acuity between the 2 compared groups. There were also no data showing a significant difference in the more frequent development of myopia in the group receiving the toric IOL. Conclusion. The correct choice and calculation of the IOL remains one of the most difficult tasks in pediatric cataract surgery. New technologies are introduced annually and require constant testing. In this study, we have shown the possibility of using toric IOLs and their positive effects in pediatric cataract surgery and in the prevention and treatment of obscuration amblyopia.

Purpose. To present the outcomes of hybrid multifocal and monofocal intraocular lenses (IOLs) and to compare with refractive and diffractive multifocal IOLs (MFIOLs).Methods. Three hundred twenty eyes (160 patients) underwent cataract surgery with randomized IOLs bilateral implantation. Changes in uncorrected and distance-corrected logMAR distance, intermediate and near (UNVA and DCNVA) visual acuity (VA), contrast sensitivity (CS), presence of dysphotopsia, spectacle independence, and patient satisfaction were analyzed.Results. Postoperative VA in the hybrid (OptiVis) group was improved in all distances (p<0.001). OptiVis acted superiorly to monofocal IOLs in UNVA and DCNVA (p<0.001for both) and to refractive ones in DCNVA (p<0.005). Distance, mesopic, without glare CS in OptiVis was lower than in the monofocal group and similar to other MFIOLs. No differences in dysphotopsia pre- and postoperatively and spectacle independence in near for OptiVis and refractive MFIOLs were detected. OptiVis patients were more satisfied than those with monofocal IOLs (p=0.015).Conclusions. After cataract surgery, patients with OptiVis improved VA in all distances. Near and intermediate VA was better than monofocal, and DCNVA was better than the refractive group. CS was lower in OptiVis than in the monofocal group, but there was no difference between MFIOLs. Patient satisfaction was higher in OptiVis than in the monofocal group. This trial is registered withNCT03512626.

Abstract Purpose To evaluate the influence of the type of the keratectasia and preoperative keratometry readings on the efficacy of implantation of iris-fixated phakic anterior chamber intraocular lenses (pIOL) in patients with keratoconus. Methods In this retrospective study, iris-fixated pIOLs (Artisan/Artiflex (Ophtec®), Verisyse/Veriflex (AMO®)) were implanted in 38 eyes of 22 patients with stable keratoconus. Thirty-six eyes underwent corneal crosslinking (CXL) prior to the lens implantation. The refractive outcome was evaluated 6 weeks postoperatively and the influence of preoperative refraction and topo- and tomographical factors were analyzed. Results The mean postoperative uncorrected distance visual acuity (UDVApost) was 0.25 ± 0.15 logMAR and was not statistically different from the mean preoperative corrected distance visual acuity (CDVApre), which was 0.24 ± 0.13 logMAR. Twenty-seven eyes (71%) reached UDVApost/CDVApre ≥ 1 (efficacy index), whereas patients with PMD-like ectasia (n = 14) showed significantly (p = 0.003) higher efficacy index (100%) than patients diagnosed with keratoconus (n = 24) (54%). Higher eccentricity of the maximum posterior elevation showed a significant beneficial influence on the efficacy index (p = 0.021). Furthermore, a higher Amsler-Krumeich stage and preoperative MAE were correlated with a worse UDVApost. The mean absolute spherical equivalent was significantly decreased from 5.71 ± 4.96 D to 1.25 ± 1.20 D (p < 0.001). No significant difference was found in endothelial cell count. Conclusion The results indicate that the implantation of phakic iris-fixated anterior chamber IOLs is a reasonable refractive option for patients with keratoconus. Keratoconus patients with a pellucidal marginal degeneration (PMD)-like appearance ectasia seem to benefit most from such procedures.

Abstract Background : This study aims to evaluate the efficacy and safety of extended depth of focus (EDOF) intraocular lenes (IOLs) in cataract surgery. Methods: All comparative clinical trials that involved bilaterally implanting EDOF IOLs in patients with cataract were retrieved from the literature database. We used random effects models to pool weighted mean differences (WMD) and risk ratio (RR) for continuous and dichotomous variables, respectively. Results: Nine studies with a total of 1336 eyes were identified. The subgroup analysis was conducted according to the type of IOLs used in the control group. Compared with monofocal IOLs, EDOF IOLs produced better uncorrected intermediate visual acuity (WMD: -0.17, 95% CI: -0.26 to -0.08, P = 0.0001) and uncorrected near visual acuity (WMD: -0.17, 95% CI: -0.21 to -0.12, P < 0.00001). EDOF IOLs resulted in reduced contrast sensitivity, more frequent halos, however, higher spectacle independence (RR: 2.81, 95% CI: 1.06 to 7.46, P = 0.04) than monofocal IOLs. Compared with trifocal IOLs, EDOF IOLs produced worse near visual acuity (MD: 0.10, 95% CI: 0.07 to 0.13, P<0.0001). EDOF IOLs performed better than trifocal IOls in contrast sensitivity, and there were no significant difference in halos and spectacle independence. Serious postoperative complications were rare, with no adverse events were reported in most studies. Conclusions: Increasing the risk of contrast reduction and more frequent halos, EDOF IOLs provided better intermediate and near VAs than monofocal IOLs. At the expense of near vision, patients receiving EDOF IOLs have better contrast sensitivity than those receiving trifocal IOLs. Halo incidence and spectacle independence of EDOF IOLs were similar to those of trifocal IOLs.

Abstract Background: Bilateral cataract is a significant cause of blindness in Ethiopia. This study aimed to identify the resources available for cataract surgery in children, and to assess current surgical practices, surgical output and factors affecting the outcome of surgery in Ethiopia. Methods: A Google Forms mobile phone questionnaire was emailed to nine ophthalmologists known to perform cataract surgery in young children.Results: All nine responded. All but one had received either 12- or 3-5-month’s training in pediatric ophthalmology with hands-on surgical training. The other surgeon had received informal training from an experienced colleague and visiting ophthalmologists. Five worked in the capital, Addis Ababa, and they worked in six public referral hospitals and one private center. Over 12 months (2017-2018) 508 children underwent surgery; 84 (17%) children had bilateral and 424 (83%) had unilateral cataract, mainly following trauma (mean 66 (range 18-145 standard deviation (SD) ±47) eyes/surgeon). There were substantially fewer surgeons per million population (nine for 115 million population) than recommended by the World Health Organization and they were unevenly distributed across the country.Methylcellulose and rigid intraocular lenses were generally available but less than 50% of facilities had a sharp vitrectomy cutter and cohesive viscoelastic. Mean travel time outside Addis Ababa to a facility offering pediatric cataract surgery was 10 hours. Conclusion: Despite the high number of cases per surgeon, the output for bilateral cataracts was far lower than required. More well-equipped ophthalmologists trained in pediatric cataract surgery are urgently required, with deployment to under-served areas.

Abstract Background Bilateral cataract is a significant cause of blindness in children in Ethiopia. This study aimed to identify the resources available for cataract surgery in children, and to assess current surgical practices, surgical output and factors affecting the outcome of surgery in Ethiopia. Methods A Google Forms mobile phone questionnaire was emailed to nine ophthalmologists known to perform cataract surgery in young children (0–5 years). Results All nine responded. All but one had received either 12- or 3–5-month’s training in pediatric ophthalmology with hands-on surgical training. The other surgeon had received informal training from an experienced colleague and visiting ophthalmologists. The surgeons were based in seven health facilities: five in the capital (Addis Ababa) and eight in six public referral hospitals and one private center. Over 12 months (2017–2018) 508 children (592 eyes) aged 0–18 years (most < 15 years) were operated by these surgeons. 84 (17%) had bilateral cataract, and 424 (83%) had unilateral cataract mainly following trauma. A mean of 66 (range 18–145) eyes were operated per surgeon. Seventy-one additional children aged > 5 years were operated by other surgeons. There were substantially fewer surgeons per million population (nine for 115 million population) than recommended by the World Health Organization and they were unevenly distributed across the country. Methylcellulose and rigid intraocular lenses were generally available but less than 50% of facilities had a sharp vitrectomy cutter and cohesive viscoelastic. Mean travel time outside Addis Ababa to a facility offering pediatric cataract surgery was 10 h. Conclusion Despite the high number of cases per surgeon, the output for bilateral cataracts was far lower than required. More well-equipped pediatric ophthalmology teams are urgently required, with deployment to under-served areas.
