Abstract
BACKGROUND Retrospective cohort study of 561 adult patients undergoing secondary intraocular lens (IOL) implantation by vitreoretinal surgeons at a single institution from April 2015 to December 2020. METHODS Patient historical factors, intraoperative/postoperative complications, and outcomes of IOL type (anterior chamber IOL versus scleral sutured IOL versus scleral fixated IOL versus. sulcus) were assessed. Primary outcomes were rates of postoperative retinal tears and rhegmatogenous retinal detachment. Secondary outcomes were rates of intraoperative endolaser, intraoperative retinal tear, and further IOL surgery. RESULTS The incidence of intraoperative retinal tears was 7.3% and not significantly different between techniques. Rates of intraoperative endolaser use were 17.5% among all techniques and not significantly different between techniques. Rates of postoperative retinal tear were low (0%-2.7%). Rates of postoperative rhegmatogenous retinal detachment were not significantly different between techniques (anterior chamber IOL 9/198 [4.5%], SFIOL 1/54 [1.9%], scleral sutured IOL 14/274 [5.1%], sulcus 2/35 [5.7%], total 26/561 [4.6%], P = 0.79). Rates of repeat IOL surgery trended higher in sulcus lenses (anterior chamber IOL 5/198 [2.5%], SFIOL 4/54 [7.4%], scleral sutured IOL 16/274 [5.8%], sulcus 5/35 [14.3%], total 30/561 [5.3%], P = 0.12). CONCLUSION Intraoperative endolaser use and intraoperative retinal tear are not uncommon in secondary IOL surgery and underscore the importance of careful vitreoretinal management among these patients.

Magyar M, Szentmáry N, Ujváry L, Sándor GL, Schirra F, Nagy ZZ, Tóth G. Indications and Outcomes of Intraocular Lens Explantation in a Tertiary Eyecare Center in Hungary between 2006 and 2020. J Ophthalmol 2024; 2024:6653621. [PMID: 38827421 PMCID: PMC11142860 DOI: 10.1155/2024/6653621] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/31/2023] [Revised: 05/05/2024] [Accepted: 05/14/2024] [Indexed: 06/04/2024] Open
Abstract
Purpose Our study aimed to evaluate the indications and outcomes of intraocular lens (IOL) explantation surgeries in a tertiary eyecare center in Hungary. Materials and Methods This retrospective study included all IOL explantation surgeries performed between 2006 and 2020 at the Department of Ophthalmology of Semmelweis University, Budapest, Hungary. There were no exclusion criteria for this study. For each patient, the demographics, clinical history, preoperative status, indications for IOL explantation, and operative and postoperative details were reviewed. Primary outcomes included explantation indications and the type of secondary implanted IOL. Results A total of 161 eyes from 153 patients were included (96 males; 62.7%); age at the time of the IOL explantation was 65.0 ± 17.4 years. The mean time between primary cataract surgery and IOL explantation was 8.5 ± 7.7 years. In total, 139 (86.3%) PCIOLs and 22 (13.7%) ACIOLs were explanted. The main indications for IOL explantation were dislocation (n = 133; 95.7%) and refractive cause (n = 2; 1.4%) in the PCIOL group. Among ACIOL explantations, the main reasons were pseudophakic bullous keratopathy (n = 14; 63.6%), dislocation (n = 4; 18.2%), and refractive cause (n = 2; 9.1%). In the PCIOL group, 115 (82.7%) primary IOLs were implanted in the capsular bag, 16 (11.5%) were sulcus fixated, and 8 (5.8%) were scleral fixated. The most frequent ocular comorbidities were previous vitrectomy (n = 50, 31.1%), previous ocular trauma (n = 45, 28.0%), glaucoma (n = 16, 9.9%), pseudoexfoliation syndrome (n = 15, 9.3%), and high axial myopia (n = 14, 8.7%). The most commonly used secondary IOL implant was the prepupillary iris-claw IOL (n = 115, 73.7%), followed by the retropupillary iris-claw IOL (n = 32, 20.5%). Uncorrected visual acuity (UCVA) was significantly better following IOL exchange in the entire sample (1.57 ± 0.61 (range: 2.40-0.05) vs. 0.77 ± 0.56 (range: 2.40-0.00); p < 0.001). Best-corrected visual acuity (BCVA) was maintained or improved in 80.7% of cases after IOL explantation. Conclusions The most common indication for IOL explantation at a tertiary eyecare center in Hungary is IOL dislocation, followed by pseudophakic bullous keratopathy. Prepupillary and retropupillary iris-claw IOL are the most frequently used secondary implants and their use resulted in a significant UCVA improvement following IOL exchange.

Managing dissatisfaction after multifocal intraocular lens implantation through lens exchange using monofocal or alternative multifocal IOLs. Acta Ophthalmol 2024. [PMID: 38780148 DOI: 10.1111/aos.16720] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/04/2024] [Accepted: 05/08/2024] [Indexed: 05/25/2024]
Abstract
PURPOSE To manage patient dissatisfaction following multifocal intraocular lens (MF-IOL) implantation by IOL exchange with either a monofocal or an alternative MF-IOL, and to compare outcomes in these two groups. METHODS MF-IOL exchange was performed in 32 patients (64 eyes) with neuroadaptation failure. The MF-to-MF group involved patients who had a MF-IOL exchanged with another MF-IOL of a different optical profile and the MF-to-MO group involved patients who had a MF-IOL exchanged to a monofocal IOL. Visual outcomes and complications were analysed. The Quality of Vision (QoV) questionnaire, Visual Function Index (VF-14) and its Rasch-revised version (VF-8R) were also used to assess outcomes. RESULTS There were no significant differences (p > 0.05) in the QoV scores between the two groups, both preoperatively and postoperatively. Preoperatively, there were no significant differences in VF-14 scores between both groups (p > 0.05). Postoperatively, there were statistically significant differences in VF-14 (total score, intermediate vision and near vision) in favour of the MF-to-MF group (p < 0.05). The postoperative VF-8R score in the MF-to-MF group was significantly better than the MF-to-MO group (p ≤ 0.001). Uncorrected and corrected near as well as corrected distance visual acuities were significantly better (p < 0.05) in the MF-to-MF group compared to the MF-to-MO group at 3 months. CONCLUSION Patient dissatisfaction and neuroadaptation failure following MF-IOL implantation can be managed by an IOL exchange with an alternative optical design of MF-IOL or a monofocal IOL. Although, in the current study, the MF-to-MF group showed some better postoperative results, both options are feasible solutions.

Abstract
Background: Due to lower age thresholds for cataract surgery and increased longevity, cases with intraocular lens (IOL) dislocation requiring removal have increased. Traditional methods, such as cutting or folding the IOL within the eye, pose a high risk of complications, including corneal endothelial and iris damage. Methods: We developed a new minimally invasive technique for direct IOL removal using specially designed lens-grabbing forceps. These forceps can grasp and remove the IOL through a small incision in a single motion, significantly reducing intraocular manipulations compared to conventional methods. Results: In our test cases, IOL removal through a 2.2 mm corneal incision was completed in approximately 95 s, with minimal incision enlargement (about 0.16 mm) and a slight decrease in corneal endothelial cells. Conclusions: Our findings suggest that this technique is minimally invasive and safe for IOL removal, offering a promising alternative to existing methods.

Abstract
PURPOSE To evaluate spherical intraocular lens (IOL) implantation for cataracts in keratoconic eyes followed by optional refractive toric lens exchange to improve uncorrected visual acuity. METHODS This retrospective study evaluated cataract surgery outcomes in keratoconic eyes. Eyes treated with a spherical IOL targeted for -2.00 diopters (D) either achieved acceptable manifest refraction and desired exchange with a toric IOL (Group 1); achieved satisfactory manifest refraction and chose to use spectacles or contact lenses (Group 2); or did not achieve acceptable refraction and used contact lenses (Group 3). Group 4 had single-stage toric IOL implantation with plano target. Corrected and uncorrected distance visual acuity (CDVA and UDVA) and keratometry were analyzed. RESULTS Groups 1 to 4 had 18, 23, 18, and 26 eyes, respectively. A staged toric exchange resulted in significantly better (P = .02) UDVA (mean: 0.15 logMAR; 20/25 Snellen) than initial toric IOL implantation (0.24 logMAR; 20/30 Snellen). All toric IOL exchange eyes achieved 20/30 or better CDVA and 94% had 20/40 or better UDVA. Mean manifest cylinder significantly decreased from 3.39 D before lens exchange to 1.10 D postoperatively. CONCLUSIONS Initial implantation of a spherical IOL in keratoconic eyes allows basing toric calculations on the manifest refraction, which may be more reliable than keratometry measurements in keratoconic eyes. UDVA after staged toric IOL exchange was significantly better than after initial toric IOL implantation. Importantly, by staging use of toric lenses, the authors avoided cases where patients required a rigid contact lens after a toric IOL was implanted. [J Refract Surg. 2024;40(4):e207-e217.].

Abstract
PURPOSE To assess risk factors for worse visual acuity (VA) outcomes after intraocular lens (IOL) exchange, and the most common postsurgical complications. DESIGN Retrospective cohort study. PARTICIPANTS Eyes from patients 18 years of age and older in the IRIS® Registry (Intelligent Research in Sight) that underwent IOL exchange in the United States between 2013 and 2019. METHODS Vision improvement compared with baseline was determined at 1 year after surgery. A multivariable generalized estimating equation model adjusting for demographic factors and baseline vision was used to identify factors associated with VA worse than 20/40 at 1 year. MAIN OUTCOME MEASURES Visual outcomes and postoperative complications after lens exchange. RESULTS A total of 46 063 procedures (n = 41 925 unique patients) were included in the analysis. Overall, VA improved from a mean ± standard deviation (SD) of 0.53 ± 0.58 logarithm of the minimum angle of resolution (logMAR; Snellen equivalent, 20/70) before surgery to a mean ± SD of 0.31 ± 0.40 logMAR (Snellen equivalent, 20/40) at 1 year. Among eyes with VA recorded at both baseline and 1 year after surgery, 60.5% achieved VA of 20/40 or better at 1 year. Vision of worse than 20/40 at 1 year was associated with greater age (odds ratio [OR], 1.16 per 5-year increase; 95% confidence interval [CI], 1.14-1.18) and higher logMAR baseline VA (OR, 1.14 per 0.1-logMAR increase; 95% CI, 1.14-1.15), as well as Black or African American (OR, 1.96; 95% CI, 1.68-2.28), Hispanic (OR, 1.82; 95% CI, 1.59-2.08), and Asian (OR, 1.48; 95% CI, 1.21-1.81) race or ethnicity versus White race, Medicaid (OR, 1.78; 95% CI, 1.40-2.25) versus private insurance, smoking history (OR, 1.22; 95% CI, 1.11-1.35), and concurrent anterior (OR, 1.65; 95% CI, 1.51-1.81) and posterior (OR, 1.53; 95% CI, 1.41-1.66) vitrectomy versus no vitrectomy. Female sex was associated with better VA at 1 year. At 1 year, epiretinal membrane (10.9%), mechanical lens complication (9.4%), and dislocation of the replacement lens (7.1%) were the most common complications. CONCLUSIONS In this large national cohort, the annual number of IOL exchanges rose steadily over time. Vision improved in 60.2% of patients; worse visual outcomes were associated with greater age, worse baseline vision, Black race, Hispanic ethnicity, Medicaid insurance, smoking, and concurrent vitrectomy. Epiretinal membrane was the most common complication. FINANCIAL DISCLOSURE(S) Proprietary or commercial disclosure may be found in the Footnotes and Disclosures at the end of this article.

Abstract
Purpose To describe the long-term outcome after intraocular lens (IOL) exchange for IOL-opacification with a focus on any occurring complications. Patients and Methods Patients with an IOL exchange for opacified IOLs (Lentis LS-502-1) were identified. Medical records and information from the treating ophthalmologists were reviewed. Visual outcomes and any occurring complications after the IOL exchange were analyzed. Results IOL exchange was performed in 48 eyes of 46 patients and significantly improved best-corrected distance visual acuity from 0.42 ± 0.32 logMar (mean ± SD) in opacified lenses to 0.25 ± 0.28 logMar after IOL exchange. Nine of the 48 eyes (19%) underwent 11 further surgical procedures for complications due to four indications: IOL dislocation (n = 2, 4%), retinal detachment (RD) (n = 6, 12%), epiretinal membrane (n = 2, 4%), and pupillary block (n = 1, 2%). Three eyes (6%) developed a temporarily elevated intraocular pressure. Temporary postoperative cystoid macular edema was found in 2 eyes (4%). Conclusion IOL exchange can restore vision owing to IOL opacification in most cases. Nonetheless, IOL exchange is not an easy or risk-free procedure. This may lead to sight-threatening complications, even in eyes without predisposing ocular comorbidities.

Abstract
AIM To identify the current surgical management of aphakia and the outcomes and complications of each technique. METHODS This cross-sectional study included ophthalmic surgeons with at least one-year experience in surgery for aphakia. A study questionnaire was formulated to collect data in Saudi Arabia and other regional countries. The questionnaire included 22 questions on demographics, preferred surgical techniques, complications and the factors related to surgeon decision and the choice for managing aphakia. RESULTS The study included 145 participants (111; 76.6% were males) with mean age of 46.7 ± 11.5 years. The mean duration of cataract surgery experience was 17.6 ± 11.1 years. Most participants (86.2%) were trained in cataract surgery. Scleral fixation of intraocular lens (SFIOL) was the most commonly preferred technique, followed by iris fixation IOL, and anterior chamber IOL (75.2%, 9%, and 15.9%, respectively). The main determinants for selection of a surgical technique were simplicity (56.6%), surgical instrument availability (48.3%), and training on the technique (47.6%). The most frequent postoperative complications were pupil distortion, high intraocular pressure (IOP), pupillary capture of the IOL, and IOL decentration. CONCLUSIONS SFIOL is the preferred surgical technique for managing aphakia. The decision to choose one technique over another is complex and is based on several factors, including technical difficulty, previous training, anatomical variations, ocular comorbidities, and the potential complications. The most frequent complications after surgical correction of aphakia are pupil distortion, high IOP, pupillary capture of the IOL, and decentered IOLs.

Abstract
AIMS To develop a new intraocular lens power selection method with improved accuracy for general cataract patients receiving Alcon SN60WF lenses. METHODS AND ANALYSIS A total of 5016 patients (6893 eyes) who underwent cataract surgery at University of Michigan's Kellogg Eye Center and received the Alcon SN60WF lens were included in the study. A machine learning-based method was developed using a training dataset of 4013 patients (5890 eyes), and evaluated on a testing dataset of 1003 patients (1003 eyes). The performance of our method was compared with that of Barrett Universal II, Emmetropia Verifying Optical (EVO), Haigis, Hoffer Q, Holladay 1, PearlDGS and SRK/T. RESULTS Mean absolute error (MAE) of the Nallasamy formula in the testing dataset was 0.312 Dioptres and the median absolute error (MedAE) was 0.242 D. Performance of existing methods were as follows: Barrett Universal II MAE=0.328 D, MedAE=0.256 D; EVO MAE=0.322 D, MedAE=0.251 D; Haigis MAE=0.363 D, MedAE=0.289 D; Hoffer Q MAE=0.404 D, MedAE=0.331 D; Holladay 1 MAE=0.371 D, MedAE=0.298 D; PearlDGS MAE=0.329 D, MedAE=0.258 D; SRK/T MAE=0.376 D, MedAE=0.300 D. The Nallasamy formula performed significantly better than seven existing methods based on the paired Wilcoxon test with Bonferroni correction (p<0.05). CONCLUSIONS The Nallasamy formula (available at https://lenscalc.com/) outperformed the seven other formulas studied on overall MAE, MedAE, and percentage of eyes within 0.5 D of prediction. Clinical significance may be primarily at the population level.

Abstract
PURPOSE To analyze the indications, complications, and early course of recovery of intraocular lens (IOL) exchange surgery. MATERIAL AND METHODS Records of patients who underwent IOL exchange during a 6-year period at a tertiary referral center were reviewed and the indications and complications after surgical intervention were analyzed. Their effects on postoperative corrected distance visual acuity (CDVA), intraocular pressure (IOP), use of IOP-lowering medications, and refractive cylindrical power were assessed. RESULTS One hundred and seventy-one eyes (165 patients) were investigated. The most frequent indication for IOL exchange was lens dislocation in 163 eyes (95.32%). The main causes of IOL dislocation were pseudoexfoliation syndrome (PEX) in 98 eyes (57.31%) and complications during cataract surgery in 40 eyes (23.39%). During IOL exchange, an anterior iris-claw fixation was performed in 159 eyes (92.98%). After significant initial deterioration to 1.59 ± 1.08 logMAR on postoperative day 1 (p ≤ 0.001), the CDVA recovered to preoperative levels within 28 days. A significant decrease in IOP was observed on postoperative day 1 (p = 0.04). The most common postoperative complications were corneal edema in 114 eyes (66.67%) and vitreous hemorrhage in 67 eyes (39.18%). CONCLUSION The high early postoperative prevalence of corneal edema and intraocular hemorrhage was found to affect visual recovery after IOL exchange, causing a significant initial deterioration of CDVA and a delay of full visual recovery. These findings suggest that surgical approaches minimizing the risk of this type of complications should be favored.

Abstract
PURPOSE To determine the indications and surgical outcomes of intraocular lens (IOL) exchange in pseudophakic patients at Labbafinejad Tertiary Referral Center between 2014 and 2019. METHODS In this retrospective interventional case series, the medical records of 193 patients with a history of IOL exchange were reviewed. Preoperative data, including clinical characteristics, indications of the first and second IOL implantation, intra- and postoperative complications due to IOL exchange, and the pre-and postoperative refractive error and best-corrected visual acuity (BCVA) were considered the outcome measures in this study. All postoperative data were analyzed at least six months after follow-up. RESULTS The mean age of our participants was 59.13 ± 20.97 years old at the time of the IOL exchange, with a male percentage of 63.2%. The mean follow-up after the IOL exchange was 15.72 ± 16.28 months. The main indications of IOL exchange were IOL decentration (50.3%), corneal decompensation (30.6%), and residual refractive errors (8.3%). 57.10% of patients with the postoperative spherical equivalent at -2.00 diopter (D) to + 2.00D. The mean best-corrected visual acuity was 0.82 ± 0.76 LogMAR before the IOL exchange and was improved to 0.73 ± 0.79 LogMAR after the surgery. Corneal decompensation (6.2%), glaucoma (4.7%), retinal detachment (4.1%), cystoid macular edema (2.1%), and uveitis (1%) were found as the postoperative complications. There was only one case with suprachoroidal hemorrhage during IOL exchange. CONCLUSIONS IOL decentration followed by corneal decompensation was the most common indication of IOL exchange. After IOL exchange, the most complications during follow-up were corneal decompensation, glaucoma, retinal detachment, and cystoid macular edema.

Abstract
PURPOSE To report the visual outcomes and quality of vision and life after bilateral implantation of a single-piece trifocal intraocular lens (IOL) in Chinese patients. SETTING Hong Kong Sanatorium & Hospital, Hong Kong, China. DESIGN Prospective, observational case series. METHODS Patients with bilateral implantation of AcrySof IQ PanOptix multifocal IOL were included. Distance, intermediate (60 cm), and near (40 cm) visual acuities (VAs) and contrast sensitivity (CS), defocus curve, preoperative higher-order aberration (HOA), dysphotopsia (0 to 5), satisfaction (1 to 5), spectacle independence, and quality of life were evaluated. The association between preoperative HOA and postoperative halos was also assessed. RESULTS 54 eyes of 27 patients were included. The mean binocular distance, intermediate, and near uncorrected VA was -0.05 ± 0.06 (20/18), 0.06 ± 0.10 (20/23), and 0.04 ± 0.05 (20/22), respectively. No eyes lost more than 1 line of vision. Binocular CS was comparable with the monocular population norm of older adults. The defocus curve demonstrated that the binocular VA of 20/25 or better was achieved at a power of -3.00 to +0.50 diopters. The mean scores for halos, glare, and starbursts were 2.4 ± 1.4, 0.2 ± 0.8, and 1.4 ± 1.4 (of 5), respectively. The mean satisfaction score was 4.3 ± 0.7 (of 5). All the patients (100%) reported total spectacle independence. The mean vision-targeted composite score of the vision-related quality-of-life questionnaire was 97.2 ± 9.7 (of 100). Preoperative HOA was not associated with postoperative halos. CONCLUSIONS Implantation of the trifocal IOL provided satisfactory visual outcomes and quality of vision and life, which resulted in a high rate of spectacle independence.

Abstract
Purpose To describe the indications, outcomes, and complications associated with intraocular lens (IOL) exchange. Patients and Methods To determine the relative frequency of postoperative complications between techniques for all patients undergoing IOL exchange from May 1, 2014 through August 31, 2020. Results IOL exchange was performed in 511 eyes of 489 patients (59.7% men; mean age: 67.0 ± 13.9 years, median time from cataract procedure to IOL exchange: 47.5 months). Mean uncorrected visual acuity significantly improved from 20/192 Snellen equivalent (logMAR 0.981) preoperatively to 20/61 (logMAR 0.487) at last follow-up (P < 0.001). Overall, 384 eyes (78.7%) met their desired refractive outcome within ±1.0 diopter (D). The most frequent complication was cystoid macular edema (CME) (n=39, 7.6%). Iris-sutured technique was associated with significantly greater frequency of subsequent IOL dislocation (10.3%) than 4-point scleral sutured (0%, P = 0.002), anterior chamber IOL (ACIOL, 1.5%, P = 0.01), and 2-point scleral sutured (0%, P = 0.03) techniques. Yamane scleral-fixation technique was associated with significantly greater frequency of developing IOL tilt (11.8%) than ACIOL (0%, P = 0.002), 4-point scleral sutured (1.1%, P = 0.01), 2-point scleral sutured (0%, P = 0.04), and iris-sutured (0%, P = 0.04) techniques. Conclusion IOL exchange significantly improved uncorrected visual acuity and more than three-quarters of eyes met the refractive goal. Certain techniques were associated with complications, including subsequent dislocation associated with iris-sutured technique and IOL tilt associated with Yamane scleral-fixation technique. This information may help guide surgeons in deciding between procedural techniques for individual patients during IOL exchange preoperative planning.

Abstract
Background The aim of the study was to evaluate the outcomes of dissatisfied patients reporting poor visual quality following implantation of multifocal intraocular lenses (MF-IOLs), managed by IOL exchange with another multifocal optical profile. Methods This is a retrospective series of cases. MF-IOL exchange was done in 15 dissatisfied patients (30 eyes) with the perception of poor visual quality for far distance affected by neuroadaptation failure. Patients underwent a bilateral exchange of a MF-IOL with another MF-IOL of a different optical profile. Visual outcomes and complications were analyzed. Questionnaires including Quality of Vision (QoV), Visual Function Index-14 (VF-14) and its Rasch-revised version (VF-8R) and a satisfaction questionnaire were also used for outcome evaluation. Results The mean elapsed time from implantation to explantation-reimplantation was 11.8 months. The QoV scores improved significantly across all the three subscales. Visual function improved with a change in VF-14 score from 60.41 ± 24.81 to 90.16 ± 10.91 (P < 0.001). The VF-8R score improved as well. The uncorrected distance visual acuity improved from 0.24 to 0.12 logMAR after exchange (P < 0.001) and corrected distance visual acuity improved from 0.15 to 0.04 logMAR (P < 0.001). Safety and efficacy indexes reached 1.46 and 1.16, respectively. Concerning patients’ satisfaction following MF-IOL exchange, 80% of the patients reported they would have the MF-IOL reimplantation procedure again. Conclusions Patient dissatisfaction with neuroadaptation failure following MF-IOL implantation can be managed in 80% of our cases by MF-IOL exchange with a different MF-IOL optical profile.

Abstract
BACKGROUND The aim of this study was to evaluate visual, refractive, quality of vision, visual function and satisfaction of multifocal intraocular lens (MF-IOL) exchange with a monofocal IOL (MNF-IOL) in dissatisfied patients following MF-IOL implantation. METHODS This was a retrospective case series. Bilateral IOL exchange (MF-IOL to MNF-IOL) was performed in 13 patients (26 eyes) with neuroadaptation failure. Questionnaires including the Quality of Vision (QoV), Visual Function Index (VF-14 and Rasch-revised VF-8R version), and a satisfaction questionnaire were used. RESULTS The mean time for IOL exchange was 15 months. The corrected distance visual acuity (CDVA) improved from 20/26 to 20/23 (P = 0.028). The uncorrected near visual acuity (UNVA) worsened after exchange from 20/47 to 20/62 (P = 0.024). QoV scores improved significantly across all three subscales after exchange. Visual function for far distance improved with a change in VF-14 score from 74.2 ± 24.8 to 90.9 ± 9.1 (P = 0.03). The VF-8R score showed worsening although not statistically significant. Near vision spectacle independence was totally or partially lost in all cases. Ten patients (77%) reported they would not repeat the lens exchange. Safety and efficacy indices changed from 1.23 to 0.85, respectively, at three months to 1.24 (P = 0.871) and 0.89 (P = 0.568), respectively, at one year. CONCLUSION IOL exchange (multifocal to monofocal) to solve neuroadaptation failure in this case series resulted in significant improvements in dysphotopsia and improved distance visual function. However, UNVA worsened and patient satisfaction after exchange remained suboptimal with 77% claiming they would not repeat the lens exchange, suggesting the value of near vision spectacle independence for these patients.

Abstract
Purpose To present a case of a 62-year-old patient implanted with multifocal intraocular lenses (IOLs) who underwent a bilateral IOL exchange due to positive dysphotopsia. In an attempt to reduce the symptoms and compensate for the loss of multifocality, we implanted an aspheric monofocal IOL with enhanced intermediate function in one eye and a spherical monofocal IOL in the other eye. Observations The patient presented with complaints of halo and glare, measured with a simulator, following the implantation of segmented multifocal IOLs two years earlier. The uncorrected distance visual acuity (UDVA) was 20/20 in both eyes. Before presentation at our clinic, a laser capsulotomy had been performed on the right eye. We proceeded with a bilateral IOL exchange. Because of capsular insufficiency in the right eye, we implanted a spherical monofocal three-piece IOL in the ciliary sulcus with optic capture. In the left eye, we used a monofocal IOL with an enhanced intermediate function. Two weeks postoperatively, UDVA (monocularly) was 20/20 in OD and OS, the uncorrected intermediate visual acuity (UIVA) was 20/32, and the uncorrected near visual acuity (UNVA) was 20/50. Binocularly, UDVA was 20/20, UIVA was 20/25 and UNVA was 20/25. The patient reported a marked decrease in halos and glare. Conclusions and importance When planning IOL exchange surgery, in cases of intolerance to multifocal IOLs, the clinician should consider the dilemma of loss of multifocality. Recent developments in monofocal IOL technology present new options to improve visual function in cases of multifocal IOL explantation.

Abstract
PURPOSE To evaluate the feasibility of scleral fixation of subluxated or dislocated multifocal/multifocal toric intraocular lenses (IOLs) to rescue the IOL and restore both near and far vision. METHOD A total of 18 eyes of 17 patients who underwent transscleral or intrascleral fixation of subluxated or dislocated multifocal or multifocal toric IOLs at 2.5 mm posterior to the limbus were enrolled. Preoperative uncorrected distance visual acuity (UDVA) and postoperative UDVA values were compared in this retrospective cross-sectional study. The postoperative corrected distance visual acuity (CDVA), uncorrected near visual acuity (UNVA) at 40 cm, residual sphere, cylinder, spherical equivalent, and IOL centration were evaluated. RESULTS The mean follow-up period was 4.0 ± 5.0 months. The mean preoperative UDVA was 0.73 ± 0.71 logMAR and the postoperative UDVA was 0.05 ± 0.10 logMAR, which was significantly improved relative to the preoperative UDVA. The mean postoperative CDVA was 0.00 ± 0.00 logMAR and the mean postoperative UNVA at 40 cm was 0.05 ± 0.07 logMAR. The mean postoperative residual sphere, cylinder, and spherical equivalent values were - 0.21 ± 0.41 D, - 0.29 ± 0.26 CD, and - 0.33 ± 0.39 D, respectively. Postoperative anterior segment photographs showed good centration of optics in all cases of single-piece foldable multifocal IOLs but a slight inferior decentration in one case of a three-piece multifocal IOL. CONCLUSION Scleral fixation of subluxated or dislocated multifocal and multifocal toric IOLs could be one of the treatment options to rescue subluxated or dislocated multifocal IOLs and restore both near and far vision.

Abstract
PURPOSE To evaluate the effectiveness of the Harmoni Modular IOL (HMIOL). SETTING 3 study sites. DESIGN Prospective, multicenter clinical study. METHODS HMIOL is a foldable, posterior chamber lens with separate base and exchangeable optic components. Eligible adults undergoing cataract surgery received HMIOL in the study eye (monovision target -1.50 diopters [D]) and standard monofocal IOL in contralateral eye (control). After 3 months, subjects could undergo optic exchange based on visual outcomes. End points included uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), and manifest refractive spherical equivalent (MRSE). Follow-up was 12 months or greater postoperatively. RESULTS 114 subjects had successful HMIOL implantation in study eye and control IOL in contralateral eye. At 3 months, subjects could undergo optic exchange if unsatisfied with monovision; 65 eyes had optic exchange (exchange cohort), and 49 eyes had no exchange (no exchange cohort). In exchange cohort, the proportion of eyes with UDVA of 20/40 or greater and of 20/20 or greater increased 3 months after optic exchange vs preexchange levels by 23% (97% vs 74%) and 40% (49% vs 9%), respectively. In all cohorts, 95% of subjects or greater achieved UDVA of 20/40 or greater after 12 months or greater. Control and no exchange cohorts achieved CDVA of 20/40 or greater by 3 months; 97% of eyes or greater had CDVA of 20/40 or greater at 12 months after optic exchange. In exchange cohort, the proportion of eyes with MRSE within ±0.50 D and ±1.00 D of target changed by 57% and 36%, respectively, from preexchange (20% and 59%, respectively) to 12 months postexchange (77% and 95%, respectively), reaching levels similar to control subjects (72% and 97%, respectively). CONCLUSIONS HMIOL provided visual outcomes comparable with standard monofocal IOLs.

Abstract
As techniques for modern cataract surgery have expanded and premium intraocular lens (IOL) use is now widespread, patient expectations are high. The need for IOL explantation, whilst still low, remains an ongoing issue. Intraocular lens explantation can be challenging for a number of reasons and as such we have introduced an additional technique to add to the surgeon's repertoire. Bimanual haptic stripping of fibrosis at the specific area where the haptic is adherent to the capsular bag is an effective strategy to aid in dissection of haptics without compromising the capsule or zonules. Given the challenges associated with IOL explantation, newly designed IOLs need to avoid these "sticking points" at which the IOLs interact with the fibrosed capsule. Techniques we have evolved and which are described below should assist anterior segment surgeons to facilitate IOL removal in an efficient and safe way.

Abstract
PURPOSE To report the indications, outcomes, and complications regarding the Bag-in-the-lens (BIL) intraocular lens (IOL) exchanges over a period of 13 years in a tertiary ophthalmologic centre. SETTING Department of Ophthalmology of the University Hospital of Antwerp (UZA). DESIGN Observational retrospective study. PATIENTS AND METHODS Between 2003 and 2020, 12 176 patients were operated using the BIL technique. We included adult patients who underwent an intraocular BIL exchange and recorded the demographics, indications, outcomes, and complications. RESULTS Fifty-nine eyes of 59 patients who underwent a BIL exchange between 2007 and 2020 were included (0.48%). The mean age was 61.15 ±13.53 years. The mean time between primary surgery and IOL exchange was 25.73 ± 41.88 months. The main indication for explantation was refractive surprise mostly related to the patients' risk factors e.g. preoperative corneal and refractive surgery. The mean preoperative uncorrected distance visual acuity (UDVA) and corrected distance visual acuity (CDVA) were 0.36 ± 0.24 and 0.79 ± 0.24 respectively. The postoperative 1 month-UDVA and CDVA were 0.66 ± 0.28 and 0.86 ± 0.19 respectively. The improvement in UDVA was statistically significant (<0.0001). The most common peroperative complication was damage to the anterior hyaloid in 9 eyes (15%), which did not prohibit reimplantation of a secondary BIL. CONCLUSIONS BIL to BIL exchange is an viable and successful technique that provides good refractive results with few, manageable complications. Because of the tertiary profile of our centre with referral of complex cases, BIL was our preferred IOL in patients at risk of postoperative refractive surprise.

Abstract
PURPOSE To evaluate the ease of replacement and capsular stability of a new fluid-filled, modular, accommodating intraocular lens (IOL) system composed of a monofocal base lens with a fluid lens clipped inside of it. SETTING John A. Moran Eye Center, University of Utah, Salt Lake City, Utah, USA. DESIGN Experimental study. METHODS Five New Zealand rabbits underwent bilateral phacoemulsification with implantation of the test lens (Juvene, LensGen, Inc.) in both eyes (4 rabbits), or a control IOL in 1 eye (AcrySof, Alcon Laboratories, Inc.) and the test IOL in the other (1 rabbit). At 2 weeks, the 4 rabbits with bilateral Juvene IOLs had the clipped-in fluid lens exchanged for a new fluid lens in 1 eye, and the base and fluid lenses exchanged for a control lens in the contralateral eye. Slitlamp examinations were performed weekly for 4 weeks. The globes were enucleated and evaluated with ultrasound biomicroscopy, grossly from the posterior Miyake-Apple view, and histopathologically. RESULTS Explantation/exchange of the fluid lens was considered straightforward by the surgeon. Explantation of the base lens (4) was also safely performed, albeit more demanding, without any signs of damage to the capsular bag under clinical, ultrasound biomicroscopy, and pathological examination in the exchanged eyes. Less capsular bag opacification was observed with the Juvene lens system. CONCLUSIONS Explantation/exchange of the fluid lens component, or both fluid and base lenses, of this new lens system can be safely accomplished if necessary, because of its modular design and the relative lack of postoperative capsular bag opacification associated with it.

Abstract
PURPOSE To report the indications, frequency, and outcomes regarding intraocular lens (IOL) exchange in 2 university hospital tertiary referral settings over a period of 15 years. SETTING Ophthalmology departments of the University Hospital Antwerp and the University Hospital Leuven, Belgium. DESIGN Retrospective cross-sectional study. METHODS In this retrospective study, included were patients who underwent an IOL exchange between 2002 and 2017. Patient demographics, surgical indication, comorbidities, visual outcomes, and complications were reported. Patients who underwent IOL repositioning or add-on IOL implantation or extraction, and patients who were left aphakic, were excluded. RESULTS Included in the study were 492 eyes. The mean age was 66.0 ± 13.3 years (range 19-91 years). The mean time between primary surgery and IOL exchange was 54.61 ± 67.07 months (range 0-343 months). Primary indication for explantation was IOL opacification, and the most common ophthalmic comorbidity was a previous history of vitreoretinal surgery. Preoperatively, the mean uncorrected visual acuity (UCVA) and corrected distance visual acuity (CDVA) were 0.47 ± 0.27 (range 0-1) and 0.61 ± 0.32 (range 0-1.2), respectively. Postoperative UCVA and CDVA was 0.7 ± 0.3 (range 0-1.2) and 0.8 ± 0.28 (range 0.05-1.6), respectively. The increase in both CDVA and UCVA was statistically significant (P < .001, paired t test). The most common complication perioperatively was vitreous prolapse, which occurred in 61 eyes (16%). CONCLUSIONS IOL exchange is a challenging yet valuable treatment option for a wide spectrum of problematic IOL outcomes. The most common indication remains IOL opacification, although IOL dislocation and patient dissatisfaction are increasing as indications.

Abstract
Purpose To compare spectacle independence, patient-reported outcomes (PROs), and dysphotopsia after multifocal intraocular lens (IOL) implantation with the AcrySof PanOptix trifocal or the ReSTOR +2.5/3.0 D or ReSTOR +2.5 D mini-monovision multifocal IOL. Patients and Methods Prospective, open-label, multicenter analysis of PROs, spectacle independence, and satisfaction among patients undergoing cataract surgery who had been implanted at least 1 month previously with AcrySof IQ PanOptix or PanOptix Toric trifocal (n = 59) IOLs bilaterally. Results were compared to outcomes from a similar study with the AcrySof ReSTOR 2.5/3.0 or the ReSTOR ActiveFocus 2.5 mini-monovision lens [n = 191]). Results Spectacle independence was significantly higher in the PanOptix cohort, with 83% of patients “never” needing glasses for any activity versus 36% in the ReSTOR 2.5 mini-monovision and 34% in the ReSTOR 2.5/3.0 cohorts. No significant differences in patient satisfaction rates were reported between the three cohorts. Glare and halo were rated “extremely” noticeable more with the PanOptix (10%) than with the ReSTOR 2.5 mini-monovision (1%) or ReSTOR 2.5/3.0 (3%). BCVA differences were not statistically significant, and no new safety concerns were reported. Conclusion The AcrySof PanOptix trifocal provides significantly greater spectacle independence across all measured activities than the AcrySof ReSTOR multifocal IOLs.

Abstract
PURPOSE To characterize safety of optic exchange using a modular lens. SETTING 3 study sites (New Zealand, Philippines). DESIGN Prospective clinical study. METHODS Harmoni modular intraocular lens (HMIOL) with separate base and optic components was implanted in the study eye (monovision target -1.5 D). Contralateral eyes received standard monofocal lenses. Subjects could elect optic exchange 3 months after primary implantation. Adverse events (AEs) and endothelial cell loss (ECL) were assessed through 12-months follow-up. RESULTS 114 subjects successfully received HMIOL and 114 received control lens in contralateral eye. At month 3, 65 HMIOL eyes had optic exchange due to unsatisfactory visual outcome from high monovision (Exchange cohort); 49 eyes received no exchange (No Exchange cohort). Exchange, No Exchange, and Control cohorts reported ocular AEs in 10 (15%), 6 (12%), and 14 (12%) eyes. No posterior capsular rupture occurred during optic exchange procedures. Short-term (12-month) posterior capsule opacification (PCO) evaluation showed all eyes had PCO grade ≤1 at month 12; no YAG capsulotomy was performed in the Exchange cohort. No Exchange and Exchange cohorts had similar ECL at 3 months versus preoperative baseline (-4.5%, n=48 and -4.0%, n=65). In the Exchange cohort, additional 2.7% ECL occurred 3 months after optic exchange compared with pre-exchange baseline; ECL was significantly below the 14% threshold (P<0.001) and was 5.8% at 12 months. CONCLUSIONS HMIOL safety outcomes were comparable with standard monofocal lenses; HMIOL may provide an effective method for correcting postoperative refractive errors.

Abstract
The review discusses modern problems of intraocular lens (IOL) exchange. Making an adequate choice between IOL reposition and IOL exchange in pseudophakic patients with problems of lens fixation remains a largely unsolved issue. The literature data shows a noticeable increase in the number of supporters of retropupillary fixation of an iris-claw lens during the exchange procedure.

Abstract
BACKGROUND To report the indications, visual outcomes, and intra-operative and post-operative complications of iris-sutured posterior chamber intraocular lens (IOL) in eyes with inadequate capsular support and complex ocular history. METHODS A chart review and data analysis of eyes that underwent iris fixation of posterior chamber (PC) IOL for correction of aphakia, dislocated and subluxed IOLs, ectopia lentis, and IOL exchange. Data included clinical risk factors, associated eye conditions, previous surgeries, and concomitant procedures. The pre-operative and post-operative vision, manifest refraction, endothelial cell density, intraocular pressure (IOP), as well as intra-operative and post-operative complications were also recorded. RESULTS One hundred and seventeen eyes from 114 patients were examined with a mean follow-up of 22.4 months. The most common identifiable predisposing risk factor was high myopia in 23 eyes. A significant improvement in uncorrected and best corrected visual acuity compared with baseline was observed. The most common post-operative complications included recurrent IOL subluxation in 16 (13.7%) eyes, IOP spike in 7 (5.9%) eyes, cystoid macular oedema in 5 (4.3%) eyes, and epiretinal membrane formation in 4 (3.4%) eyes. There was one (0.85%) case of sterile endophthalmitis. CONCLUSIONS Iris suture fixation of PC IOLs is a good treatment option for eyes with inadequate capsular support and complex ocular history.

Abstract
PURPOSE To compare complication rates, visual acuity, and refractive outcomes of secondary intraocular lens (IOLs) implantation. SETTING Department of Ophthalmology, Cullen Eye Institute, Baylor College of Medicine, Houston, Texas, USA. DESIGN Retrospective case series. METHODS All secondary IOLs placed by the anterior segment service were reviewed. Preoperative data, operative reports, and data from each subsequent postoperative visit were evaluated. Patients were divided into 5 groups based on the final IOL position: (1) sulcus with optic capture, (2) sulcus without optic capture, (3) anterior chamber (AC), (4) iris-fixated, and (5) transscleral-sutured. Complication rates, visual acuity, and refractive outcomes were compared for each group. RESULTS The sulcus with and without optic capture groups had the lowest complication rates and best visual acuity outcomes. There was no difference in final corrected distance visual acuity (CDVA) between the transscleral-sutured IOL, iris-fixated IOL, and AC IOL groups, although the AC IOL group had the lowest rates of early postoperative complications and a significant improvement in vision. The transscleral-sutured IOL group had the highest complication rates, and 25% of patients in the iris-fixated IOL group lost 2 or more lines of CDVA. CONCLUSIONS When a secondary IOL cannot be placed within the capsular bag, sulcus with optic capture is the best alternative, followed by sulcus without optic capture. There was no difference in visual acuity outcomes between transscleral-sutured IOLs, iris-fixated IOLs, and AC IOLs. Anterior chamber IOLs resulted in fewer early complications.

Abstract
PURPOSE To evaluate the causes of IOL explantation, techniques for secondary IOL implantation, visual outcomes and complications. METHODS Setting: Department of Ophthalmology Complexo Hospitalario Universitario A Coruña, Spain. DESIGN Retrospective study. All explanted IOLs from January 2010 to June 2018 were included. Medical records were reviewed to determine the surgical indication for IOL explantation, type of IOL implanted, time between surgeries, visual outcomes and surgical complications. RESULTS One hundred forty-one IOLs were explanted (134 patients). Mean time from original surgery to IOL explantation was 7.89 ± 5.81 years. Causes of IOL explantation were IOL dislocation (81.56%)-in-the-bag IOL dislocation (71.63%), out-of-the-bag IOL dislocation (9.9%)-corneal decompensation (12.05%), refractive surprise (3.5%), uveitis-glaucoma-hyphema syndrome (1.4%), IOL opacification (1.4%). Procedures for secondary IOL implantation were retropupillar iris-claw IOL (63.8%), flanged scleral fixated IOL (9.2%), three-piece IOL in ciliary sulcus (8.5%), angle-supported anterior chamber IOL (7.1%), in-the-bag IOL (3.5%), scleral fixated IOL with sutures (0.7%). Ten cases (7.1%) were left aphakic. Mean preoperative and postoperative logMAR CDVA were 1.34 ± 0.87 and 0.63 ± 0.69, respectively (p = 0.000). Mean preoperative IOP and postoperative IOP were 16.78 ± 4.49 and 15.53 ± 3.476 mmHg, respectively (p = 0.005). Complications include cystoid macular edema (7.8%), glaucoma (7.1%), IOL luxation (2.1%), retinal detachment (1.4%), trophic ulcer and leucoma (1.4%), corneal decompensation (1.4%). CONCLUSIONS In-the-bag IOL dislocation was the most frequent indication for IOL explantation, followed by pseudophakic bullous keratopathy. Simultaneous IOL exchange for a retropupillar iris-claw IOL was the most frequent procedure for secondary IOL implantation. Mean CDVA improved significantly and IOP decreased significantly after IOL explantation. The most frequent postoperative complication was cystoid macular edema.

Abstract
Intraocular lens (IOL) exchange after cataract surgery is unusual but may be associated with suboptimal visual outcome. The incidence of IOL exchange has not been consistently estimated. Such information is invaluable when counseling patients prior to cataract surgery. We examined the incidence of, and indications and risk factors for, IOL exchange after cataract surgery. We also assessed visual outcome of eyes that had an IOL exchange. A cohort design was used to estimate the incidence of IOL exchange and a case-control design to identify factors associated with it. All phacoemulsification surgeries with IOL (n = 17415 eyes) during 2010–2017 and those that had a subsequent IOL removal or replacement during the same time period were identified (n = 34 eyes). The incidence of IOL exchange was 2 per 1000 surgeries (95% confidence interval [CI] 1 to 3) over 8 years. Eyes that underwent subsequent IOL removal or replacement were compared with eyes that had cataract surgery only (n = 47) across demographic and clinical characteristics. In a binary logistic regression analysis, two factors were significantly associated with IOL exchange/removal: an adverse event during cataract surgery (adjusted odds ratio [aOR] 19.45; 95% CI 4.89–77.30, P < 0.001) and a pre-existing ocular comorbidity (aOR 10.70; 95% CI 1.69–67.63, P = 0.021). The effect of gender was marginally significant (P = 0.077). Eyes that underwent IOL exchange or explantation were nearly two and a half times more likely to have a final best-corrected visual acuity of <20/60 compared to those that had cataract surgery alone (adjusted RR 2.60 95% CI, 1.13–6.02; P = 0.025).

Abstract
BACKGROUND AND OBJECTIVE To describe the reasons for and clinical outcomes of intraocular lens (IOL) removal, with or without exchange, in the setting of retina surgery. PATIENTS AND METHODS This is a retrospective, noncomparative, consecutive, interventional case series of patients undergoing IOL removal at an academic referral center performed by a single surgeon between 2002 and 2013. Data collected included baseline patient characteristics, visual acuity (VA), type of IOL, reason for IOL removal, and postoperative complications. RESULTS The study cohort included 63 eyes with IOL removal. Of these, 51 (81%) were left aphakic. For cases of IOL opacification or dislocated IOL (56), the decision to remove was made for 35 (63%) during concurrent retinal surgery due to obstruction in visualization. Overall, the most common reason for removal of the IOL was IOL opacities in 42 eyes (67%), followed by nonspecific nature of opacities (n = 19; 45%), oil artifact (n = 17; 40%), opaque nonvascular membranes (n = 4; 10%), and fibrovascular proliferation (n = 2; 5%). Other causes for removal were IOL dislocation (n = 14; 22%), endophthalmitis (n = 7; 11%), and broken IOL haptic (n = 1; 2%). The composition of the 42 IOLs with opacification included 19 (45%) silicone, 14 (33%) unspecified, five (12%) polymethyl methacrylate, and four acrylic (10%). From the 17 IOLs removed due to oil opacification, 15 (83%) were silicone, and two (17%) were unspecified. Postoperative complications included recurrent retinal detachment (n = 13; 21%), hypotony (n = 8; 13%), phthisis bulbi (n = 8; 13%), corneal edema (n = 7; 11%), cystoid macular edema (n = 5; 8%), elevated intraocular pressure (n = 3; 5%), vitreous hemorrhage (n = 3; 5%), hyphema (1; 2%), anterior synechiae (1; 2%), and subretinal hemorrhage (1; 2%) The mean (SD) immediate, 3 months, and final best-corrected VA in logMAR were 2.18 (0.47), 1.85 (0.82), and 1.97 (0.85). CONCLUSION The vitreoretinal surgeon must be prepared for IOL removal, especially if IOL opacification and dislocation compromise the view or capability to achieve primary retinal reattachment objectives.

Abstract
An 86-year-old Asian man with asteroid hyalosis presented with decreased vision in the left eye. He underwent phacoemulsification and implantation of silicone intraocular lens (IOL) in the left eye 18 years ago, and also received neodymium:yttrium–aluminum–garnet (Nd:YAG) laser 3 years ago. At presentation, his corrected visual acuity (CVA) was 20/1000 in the left eye. Slit-lamp examination showed white-gray membranous deposits on the posterior IOL surface. The deposits were removed using Nd:YAG laser treatment. One week later, his CVA improved to 20/30, and opacity of the posterior IOL surface was removed. Six months later, his CVA was 20/30, and visual axis was clear. This case suggests that Nd:YAG laser treatment can be a viable option in some patients with posterior surface opacification of silicone IOL associated with asteroid hyalosis, especially in those who are a poor candidate for IOL exchange due to old age or compromised general condition.

Abstract
We describe a technique for repositioning an encapsulated, posteriorly dislocated silicone plate-haptic toric intraocular lens (IOL) while preventing further dislocation into the vitreous cavity. Sutures of 10-0 polypropylene were used to ensure safe retrieval of the dislocated IOL. An anterior vitrectomy was then performed to remove the contracted capsular bag around the IOL. The IOL fixation hole was temporarily externalized to allow quick and secure IOL fixation, eliminating the risk for losing the slippery silicone IOL into the vitreous cavity. Using this technique, the IOL was successfully placed in the proper position and resulted in good vision for the patient while avoiding the trauma of lens exchange.

Abstract
PURPOSE To examine the incidence and trends of late intraocular lens (IOL) dislocation/decentration and the frequency of pseudophakodonesis. DESIGN Prospective, population-based cohort study. METHODS A total of 800 patients were examined before cataract surgery in 1997-1998. Twenty years later, 100 of 133 survivors (75%) participated in the follow-up. An eye examination was performed including assessment for pseudophakodonesis and dislocation of the IOL. The medical records of all included patients at baseline were studied. Main outcome measures were previous IOL exchange or repositioning surgery, significant IOL dislocation, degree of pseudophakodonesis, and visual acuity. RESULTS Twenty years after the original cataract surgery, 10 of the 800 patients at risk (1.2%) had needed dislocation surgery. Before cataract surgery, 39% of all patients had pseudoexfoliations (PXF). Mean time from cataract surgery to dislocation surgery was 12 years 6 months (range 3 years 9 months to 19 years 3 months). The cumulative incidence over 20 years was 6% in patients with PXF and 2% without PXF at surgery (P = .035). Mean age at cataract surgery in the 10 dislocated cases was 68.3 years (range 58-80). Twenty years after surgery, 5 of 98 (5%) patients had moderate/pronounced pseudophakodonesis. CONCLUSIONS In this population-based cohort, the 20-year cumulative incidence of IOL dislocation needing surgical attention was significantly higher in patients with PXF than without PXF before surgery. The individual patient seems to have a low risk of being affected by this complication, but dislocated IOLs may cause a relatively large public health care burden, because of the large number of people in society with previous cataract surgery.

Abstract
Asteroid hyalosis is a relatively common cause of vitreous opacities, which is possibly associated with diabetes mellitus and hereditary pigmentary retinopathies. We review the history, epidemiology, and biochemistry of asteroid hyalosis, as well as its relationship with ocular and systemic conditions. We describe imaging modalities used for diagnostic evaluations in cases of severe asteroid hyalosis and propose hypotheses regarding its lack of significant effects on vision. We discuss cataract surgery in patients with asteroid hyalosis and the selection of intraocular lenses for implantation.

Abstract
PURPOSE To investigate preoperative ocular risk factors and indications for secondary intraocular lens (IOL) implantation and compare postoperative complications, visual and refractive outcomes in a tertiary referral center. METHODS Patients older than 14 years that underwent secondary IOL implantation and had a minimum follow-up of 3 months were enrolled in this retrospective case series. Preoperative ocular risk factors, indications for surgery, postoperative complications, and visual and refractive outcomes including prediction error (PE) and absolute error (AE) were evaluated. IOLs were fixated in following positions: anterior chamber (AC), retropupillary iris-claw (IC), sulcus, and capsular bag or sclera. RESULTS One-hundred eighty-two eyes of 174 patients with mean follow-up of 17 ± 13.6 months were evaluated. Leading cause for surgery was IOL dislocation (75%), followed by secondary aphakia (19%) and IOL opacifications (6%). Previous vitrectomy was the major preoperative ocular risk factor (43%). Mean corrected distance visual acuity improved from preoperative 0.68 ± 0.55 to 0.42 ± 0.31LogMAR by the last follow-up (p = 0.001). PE and AE differed highly depending on the indication for surgery (p = 0.041 and p = 0.008, respectively) and the IOL fixation (p = 0.011 and p = 0.028, respectively), with IC-IOLs showing the lowest PE and AE. Postoperative AC-hemorrhage occurred mainly after IC-IOLs (p = 0.003), and postoperative hypotony was significantly higher in eyes with previous uveitis (p = 0.026). CONCLUSIONS Previous vitrectomy seems to be a major underreported risk factor in eyes that undergo secondary IOL implantation. Refractive outcomes depend on indication for surgery and fixation type, with retropupillary IC-IOLs providing the best refractive results, though not statistically significant compared to other IOL positions.

Abstract
UNLABELLED We describe the use of the capsular anchor (AssiAnchor) to manage a subluxated intraocular lens (IOL) in the capsular bag. The anchor comprises 2 prongs that hold the anterior lens capsule and a central rod that is sutured to the scleral wall, enabling centration of the IOL-capsular bag complex. Six pseudophakic patients presenting with subluxated posterior chamber IOLs in the capsular bag were operated on using the device. The anchor was used successfully in all cases, although in 2 cases only 1 prong was placed under the capsulorhexis edge. In 1 eye, 2 anchors were used 1 month apart following repeated traumatic zonular injury. The capsular bag holding the IOL remained centered and stable throughout the follow-up period. The anchoring device, which was originally designed to preserve the lens capsule and stabilize subluxated crystalline lenses, can also be used to treat subluxation of a capsular bag-fixated IOL. FINANCIAL DISCLOSURE Dr. Assia is the inventor of the AssiAnchor, has a licensed patent of the anchor, and is consultant to Hanita Lenses. Dr. Lapid-Gortzak is a consultant to and speaker for Alcon Surgical, Inc., Hanita Lenses, Orca Surgical, and Sanoculis Ltd.; a speaker for Santen; and a consultant to Icon. Drs.

Abstract
PURPOSE To identify indications for and visual outcomes of intraocular lens (IOL) exchange to understand recent changes in this surgery. SETTING Academic tertiary referral center. DESIGN Retrospective case series. METHODS Cases were identified by searching the institution's electronic medical records from January 2010 to September 2015 for patients treated by 1 staff physician with the American Medical Association's Current Procedural Terminology code for IOL exchange. These cases were reviewed to determine the surgical indication, type of IOL removed, type of IOL implanted, time between surgeries, surgical complications, and visual outcomes. RESULTS The study comprised medical records of 109 eyes. The mean time between the primary cataract surgery and IOL exchange was 1657 days. Dislocation of an in-the-bag posterior chamber IOL (27.5%), intolerance of a multifocal IOL (18.3%), and uveitis-glaucoma-hyphema syndrome (11.9%) were the most frequent indications for IOL exchange. The final IOL position after exchange was most frequently in the capsular bag (43.1%), anterior chamber (25.7%), or sulcus (22%). The final visual acuity at 1 month was 20/40 or better in 78.9% of cases. Of those not achieving this level of acuity, pathology not related to exchange surgery was identified in 48% of cases. The most frequent complications after IOL exchange surgery were posterior capsule opacification (13.8%), cystoid macular edema (10.1%), and high astigmatism (>1.5 diopters) (8.3%). CONCLUSIONS The most frequent indication for IOL exchange surgery was dislocated IOLs; the second most frequent indication was patient dissatisfaction after multifocal IOL implantation. The increased ability to place an intracapsular IOL with few intraoperative complications and largely treatable postoperative complications enhances the effectiveness of IOL exchange surgery and patient satisfaction.

Abstract
BACKGROUND We evaluated the long-term biocompatibility and safety of a new modular posterior chamber intraocular lens (IOL) system in rabbit eyes. METHODS Seven New Zealand rabbits underwent bilateral phacoemulsification with placement of the modular IOL in OD and a control IOL (SA60AT) in OS. Slit-lamp examinations were performed at postoperative weeks 1, 2, 3, 4, 6 and 8 and months 3 and 6. All rabbits were then sacrificed and eyes enucleated. The eyes were examined grossly from the Miyake-Apple view. Selected IOLs were explanted and underwent surface staining for implant cytology. All globes were then sectioned and processed for histopathological examination. RESULTS The modular IOL remained stable in all seven rabbits through the entire follow-up period. Biocompatibility was better than the control lens at six months postoperatively, on account of less extensive synechiae formation as assessed by slit-lamp examination. At the six-week examination, posterior capsule opacification (PCO) was significantly better in the test group (scored as 1.71 ± 0.8 versus 3.28 ± 0.48 in the control group, p = 0.0008). On gross examination with the Miyake-Apple view, Soemmering's ring formation was significantly better in the test group, (5.14 ± 1.57 versus 10.85 ± 1.95 in the control group, p = 0.002). CONCLUSION Previous studies showed that explantation/exchange of the modular system optic was safer and easier than with a standard IOL. The new modular IOL system has demonstrated better long-term biocompatibility compared to the control lens at six months postoperatively in the rabbit model.

Abstract
PURPOSE To determine the population-based incidence of pseudophakic intraocular lens exchange in Olmsted County, Minnesota. DESIGN Retrospective review of a population-based cohort. METHODS Patients undergoing pseudophakic intraocular lens exchange in Olmsted County, Minnesota, between January 1, 1986 and December 31, 2016 were identified from the Rochester Epidemiology Project medical record linkage system. Indications and outcomes were determined, and the incidence rate was calculated as cases per 1 000 000 person-years. Poisson regression analysis was used to assess changes in incidence over time, and the cumulative probability of needing a lens exchange was estimated by Kaplan-Meier analysis. RESULTS Eighty cases of intraocular lens exchange were identified, yielding an overall age- and sex-adjusted incidence rate of 28.4 per million (confidence interval [CI], 22.1-34.7), which increased over the study period (P = .04). The 30-year cumulative probability of intraocular lens exchange among patients undergoing cataract surgery was 1.5% (CI, 0.6%-2.4%), increasing at a relatively constant rate. Dislocated lenses accounted for 72.5% of lens exchanges. Unplanned refractive outcome of primary cataract surgery and uveitis-glaucoma-hyphema syndrome from squared-edged haptics emerged as newer indications for intraocular lens exchange. CONCLUSIONS The population-based incidence of pseudophakic intraocular lens exchange has increased over the last 30 years, and can be explained by the increase in incidence rate of cataract surgery over the same period. Surgeons should be aware of emerging indications of intraocular lens exchange, which reflect changes in lens design and increasing expectations of refractive outcomes.

Abstract
Purpose To compare refractive and visual outcomes, patient satisfaction, and complication rates among different age categories of patients who underwent refractive lens exchange (RLE). Methods A stratified, simple random sample of patients matched on preoperative sphere and cylinder was selected for four age categories: 45–49 years (group A), 50–54 years (group B), 55–59 years (group C), and 60–65 years (group D). Each group contained 320 patients. All patients underwent RLE with a multifocal intraocular lens at least in one eye. Three months postoperative refractive/visual and patient-reported outcomes are presented. Results The percentage of patients that achieved binocular uncorrected distance visual acuity 20/20 or better was 91.6% (group A), 93.8% (group B), 91.6% (group C), 88.8% (group D), P=0.16. Binocularly, 80.0% of patients in group A, 84.7% in group B, 78.9% in group C, and 77.8% in group D achieved 20/30 or better uncorrected near visual acuity (P=0.13). The proportion of eyes within 0.50 D of emmetropia was 84.4% in group A, 86.8% in group B, 85.7% in group C, and 85.8% in group D (P=0.67). There was no statistically significant difference in postoperative satisfaction, visual phenomena, dry eye symptoms, distance or near vision activities. Apart from higher rate of iritis in the age group 50–55 years, there was no statistically significant difference in postoperative complication rates. Conclusion RLE can be safely performed in younger as well as older presbyopes. No significant difference was found in clinical or patient-reported outcomes.

Abstract
Objectives: To evaluate the demographics, surgical indications and clinical results of patients with repositioned or explanted intraocular lens (IOL) in a tertiary referral eye hospital. Materials and Methods: Forty-eight eyes of 48 patients that underwent surgery to exchange or reposition the IOL at Ulucanlar Eye Training and Research Hospital between 2009 and 2013 were included in the study. Medical records of patients were evaluated for surgical indications, time elapsed since initial operation, preoperative and postoperative best corrected distance visual acuity and the presence of ocular disease. Results: The mean age of the 31 male and 17 female patients was 64.91±14.26 years. Median time between the initial and final operations was 36.0 months. Pseudoexfoliation syndrome (PEX) was present in 25% of the patients. There was history of previous vitreoretinal surgery in 18.8% of patients, ocular trauma in 6.3%, high myopia and refractive surgery in 4% of patients. In the first operation the IOL was implanted in the sulcus in 50%, in the bag in 27.1%, and in the anterior chamber in 20.8%; following the final surgery the IOL was in the sulcus in 27.1%, in the anterior chamber in 22.9%, and fixated to the sclera in 10.4% of the patients, while the remaining 29.1% remained aphakic. Indication for the secondary surgery was IOL dislocation in 58%, corneal decompensation in 20.8% and IOL degeneration in 6.3%. In the final surgery, IOL was exchanged in 54.2% of the cases, removed in 31.3% of cases, and repositioned in 14.6%. Visual acuity improved by 1-3 lines in 52.3% and remained stable in 13.6% of the patients postoperatively. Conclusion: IOL exchange may be necessary at any time following cataract surgery due to surgical complications, IOL dislocation, biometric measurement errors and corneal decompensation. Factors such as vitreoretinal surgery and the existence of PEX increase the risk of IOL exchange surgery.

Abstract
PURPOSE To investigate the nature and characteristic features of deposits causing opacification of intraocular lenses (IOLs) based on the examination of clinical findings using scanning electron microscopy (SEM) and energy-dispersive x-ray spectroscopy (EDX) analysis. DESIGN Retrospective, observational case series. METHODS This is a multicenter study of 6 hydrophilic acrylic IOLs (Lentis LS-502-1; Oculentis GmbH, Berlin, Germany) with a hydrophobic surface that were explanted from 5 patients because of opacification. Three patients had an uncomplicated phacoemulsification. One patient underwent combined phacoemulsification and pars plana vitrectomy for retinal detachment and later silicone oil endotamponade owing to redetachment. The last patient had a pars plana vitrectomy and silicone oil instillation combined with phacoemulsification for tractive retinal detachment and diabetic retinopathy. The explanted lenses were submitted to our laboratory and were examined by SEM and EDX in order to identify the morphologic features and the composition of the deposits. RESULTS SEM and EDX analyses confirmed the presence of calcific deposits in the interior of the opacified hydrophilic IOLs, with a pattern showing the formation of lumps on the surface. The lumps were due to subsurface formation of calcium phosphate crystalline deposits. The crystallite clusters seemed to diffuse from the IOL interior to the surface. CONCLUSIONS We demonstrated the calcification pattern of the hydrophilic IOL (Lentis LS-502-1) with a hydrophobic surface. Although hydrophilic acrylic lenses have a hydrophobic surface, the development of calcification is a possible threat initiating from the hydrophilic subsurface of the IOLs.
