[PMID: 39039537 PMCID: PMC11265132 DOI: 10.1186/s12886-024-03570-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/15/2024] [Accepted: 07/11/2024] [Indexed: 07/24/2024] Open
Abstract
BACKGROUND The aim of this study was to analyze the causes and characteristics of IOL explantation within the first year after primary implantation. METHODS In this retrospective, cross sectional database study, a database consisting of over 2500 IOL explants sent from 199 national and international doctors over the past 10 years was analyzed. All IOLs explanted within the first year after implantation were included in this analysis. Explants with insufficient information as well as phakic and Add-on IOLs were excluded. Main outcome measures were the reason for explantation, the time between implantation and explantation, as well as IOLs' and patients' characteristics. Additionally, the explanted IOLs were microscopically and histologically analyzed, as required. RESULTS Of all explanted IOLs from the database, 1.9% (n = 50) were explanted within the first year after implantation. The most frequent reasons for early IOL explantation were IOL dislocation (32%), visual intolerance (26%), opacification (20%), and intraoperative complications (16%). The time between implantation and explantation was the shortest in cases with intraoperative complications (1.5 ± 3.1 days), followed by IOL dislocation (90.9 ± 103.9 days), visual intolerance (98.3 ± 86.5 days), opacifications (253.5 ± 124.0 days) and other indications (249.7 ± 124.0 days). Calcification of hydrophilic IOLs was the main type of opacification (80%). Notably, seven IOLs required immediate intraoperative exchange due to an intraoperative crack in the optic or a torn off haptic. CONCLUSION Indications for early IOL explantation were IOL dislocation, visual intolerance, opacification, and intraoperative complications. Especially intraoperative damages to the IOL and early calcification show a potential for improvement of affected IOLs and implantation systems.

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.

Ophthalmology 2024; 131:403-411. [PMID: 37858872 DOI: 10.1016/j.ophtha.2023.10.021] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/19/2023] [Revised: 09/27/2023] [Accepted: 10/12/2023] [Indexed: 10/21/2023] Open
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 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 determine the current prevalence and trends of pseudophakia in a well-defined U.S. population, calculating values for Olmsted County, Minnesota, from 1988 through 2018. SETTING Mayo Clinic, Rochester, Minnesota. DESIGN Population-based cohort study. METHODS Rochester Epidemiology Project (REP) databases were used to identify all cases of pseudophakia in Olmsted County, Minnesota, between January 1, 1988, and December 31, 2018. Age- and sex-specific prevalence rates were calculated in 1988, 1998, 2008, and 2018 using REP census population estimates and mortality counts. Poisson regression analysis was used to assess changes in prevalence over time. Mortality rates were estimated by Kaplan-Meier analysis. RESULTS In 2018, 10 024 county residents were pseudophakic in at least 1 eye, for a total population prevalence of 6.5%. The prevalence increased 67% in the last 10 years and 590% in the last 30 years (P < .001). By 2018, 51% of residents aged 75 years and 88% of residents aged 85 years and older were pseudophakic in at least 1 eye, 53% of residents with pseudophakia aged 65 years and older were bilaterally pseudophakic, and 29% of residents with pseudophakia had lived with pseudophakia for more than 10 years. The prevalence was higher among women than men and increased with age (P < .001). Overall, pseudophakia had a lower all-cause mortality compared with the general Minnesota population (P < .001). CONCLUSIONS In 2018, most residents aged 75 years and older were pseudophakic in at least 1 eye. These numbers underscore the changing visual status of older adults and the large number of adults who benefit from cataract surgery.

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.

Incidence and Characteristics of Intraocular Lens Dislocation after Phacoemulsification: An Eight-Year, Nationwide, Population-Based Study. J Clin Med 2021; 10:jcm10173830. [PMID: 34501279 PMCID: PMC8432084 DOI: 10.3390/jcm10173830] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/22/2021] [Revised: 08/12/2021] [Accepted: 08/26/2021] [Indexed: 11/17/2022] Open
Abstract
BACKGROUND We investigate the incidence and characteristics of IOL dislocation among the pseudophakic population after phacoemulsification. METHODS National data were collected from the health claims recorded with the Health Insurance Review and Assessment Service of South Korea from 2009 to 2016. Pseudophakic patients aged 40 years or older were included. The incidence estimates of phacoemulsification and IOL dislocation were analyzed, and the cumulative probabilities of IOL dislocation among the pseudophakic population and general population were calculated as a proportion. RESULTS Of 51,307,821 total subjects, 25,271,917 of whom were aged 40 years or older, 3,906,071 cataract cases in 2,650,104 pseudophakic patients were identified, and 72,309 patients experienced IOL dislocation. The cumulative probability was 2.73% per person and 1.85% per surgery among patients 40 years of age or older. The eight-year incidence rate for IOL dislocation in the pseudophakic population aged 40 years or older was 7671 per 1,000,000 person-years (95% CI: 7616-7727), including 10,341 cases in men and 5814 in women. Incidence peaked in the seventh decade of life for cataract surgery but in the fifth decade of life for IOL dislocation. The cumulative probability of IOL dislocation after phacoemulsification was approximately 2%, and the incidence rate was about 7000 per 1,000,000 pseudophakic patients. CONCLUSIONS There was a significantly higher incidence of IOL dislocation among young males, even though the higher incidence of cataract surgery was observed among older females. These estimates of the nationwide, population-based incidence of IOL dislocation can help increase understanding of the population vulnerable to IOL dislocation.

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
PURPOSE To determine the cost effectiveness of an adjunctive screening OCT during the preoperative evaluation of a patient considering cataract surgery with a multifocal intraocular lens (IOL) implantation. DESIGN Cost-effectiveness analysis. PARTICIPANTS A 67-year-old man with 20/60 vision undergoing evaluation for first-eye cataract surgery. METHODS The cost-effectiveness analysis of the reference patient undergoing a preoperative cataract examination with and without a screening OCT was performed, evaluating for vitreoretinal diseases including an epiretinal membrane, age-related macular degeneration, vitreomacular traction, and cystoid macular edema. It was assumed that patients with macular pathologies detected before surgery would receive a monofocal IOL and be referred to a retina specialist for evaluation and management. The Medicare reimbursable cost of an OCT was $41.81. All costs and benefits were adjusted for inflation to 2019 United States dollars and discounted 3% per annum over a 16-year time horizon. Probability sensitivity analyses and 1-way deterministic sensitivity analyses were performed to assess for uncertainty. MAIN OUTCOME MEASURES Incremental cost-effectiveness ratio and incremental cost-utility ratio (ICUR) measured in quality-adjusted life years (QALYs). RESULTS Approximately 20.5% of patients undergoing cataract surgery may have macular pathologies, of which 11% may not be detected on the initial clinical examination. In the base case, an adjunctive preoperative OCT was cost effective from a third-party payer and societal perspective in the United States. In the probability sensitivity analyses, the ICURs were within the societal willingness-to-pay threshold of $50 000/QALY in approximately 64.4% of the clinical scenarios. CONCLUSIONS A preoperative screening OCT during the evaluation of a patient considering a multifocal IOL added to the costs of the cataract surgery, but the OCT increased the detection of macular pathologies and improved the QALYs over time. An adjunctive screening OCT can be cost effective from a third-party payer and societal perspective.

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.
