Abstract
PURPOSE Risk communication is an integral aspect of shared decision-making and evidence-based patient choice. There is currently no recommended way of communicating risks and benefits of cataract surgery to patients. This study aims to investigate whether the way this information is presented influences patients' perception of how risky surgery will be. METHODS AND ANALYSIS Two-arm parallel randomised study and patients referred for cataract surgery were assigned to receive information framed either positively (99% chance of no adverse effects) or negatively (1% chance of adverse effects). Subsequently, patients rated their perceived risk of experiencing surgical side effects on a 1-6 scale. RESULTS This study included 100 patients, 50 in each study group. Median (IQR) risk perception was 2 (1-2) in the positive framing group and 3 (1-3) in the negative framing group (p<0.0001). Risk framing was the only factor that was significant in risk perception, with no differences found by other patient clinical or demographic characteristics. CONCLUSION Patients who received positive framing reported lower risk scores for cataract surgery than patients who received negative framing. Patient factors were not identified as significant determinants in patients' perceived risk. Larger longitudinal studies are warranted to further investigate.

Abstract
Objective: To evaluate the progress of cataract surgery in a training institution providing tertiary care since the removal of pandemic restrictions. To evaluate ocular and demographic characteristics of cataract cases in a tertiary care teaching institution since the lifting of pandemic restrictions. Methods: Patients who underwent cataract surgery in our clinic in the pre-pandemic period September 2019-March 2020 (group 1, n=353) and in the post-pandemic period September 2021-March 2022 (group 2, n=459) were retrospectively screened. The cases were operated by two educator ophthalmologists and residents. The main parameters evaluated were cataract morphology, surgical parameters, and posterior capsular rupture complications. Results: The case rate increased by 30% in group 2 once pandemic restrictions were relaxed. Preoperative best corrected visual acuity (BCVA) in groups 1 and 2 was 0.840±0.63 and 1.26±0.75 log MAR, respectively (p<0.001). The percentage of mature cataracts was 15.3% in group 1 and 31.2% in group 2 (p<0.001). Significantly higher cumulative dissipated energy (CDE), total aspiration time, and fluid amount (p<0.001 for all) were found in group 2. During the training phase, 25.2% of the cases in group 1 and 24.6% in group 2 were performed by resident doctors (p=0.870). Residents in groups 1 and 2 had mature cataract case rates of 6.7% and 13.3%, respectively (p<0.001). The incidences of posterior capsule rupture in the instances of residents was 3.4% in group 1 and 4.4% in group 2 (p=0.498). A negative correlation (r=-0.424, p<0.001) between CDE and BCVA and a positive correlation (r=0.40, p<0.001) between cataract hardness and CDE were both found. Conclusions: The number of cataract surgeries increased after the COVID-19 pandemic. Poor vision and increasing rates of mature cataracts are other effects of this backlog. Residents have to deal with challenging cases. Our results are just the tip of the iceberg. Urgent planning is needed to deal with the remaining cases. Abbreviations: COVID-19 = coronavirus infection, PCR = posterior capsular rupture, BCVA = best corrected visual acuity, IOP = intraocular pressure, CDE = cumulative dissipated energy, TAT = total aspiration time, ZD = zonular separation.

Associations between vision impairment and vision-related interventions on crash risk and driving cessation: systematic review and meta-analysis. BMJ Open 2023; 13:e065210. [PMID: 37567751 PMCID: PMC10423787 DOI: 10.1136/bmjopen-2022-065210] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/01/2022] [Accepted: 07/28/2023] [Indexed: 08/13/2023] Open
Abstract
OBJECTIVES To systematically investigate the associations between vision impairment and risk of motor vehicle crash (MVC) involvement, and evaluate vision-related interventions to reduce MVCs. DESIGN Medline (Ovid), EMBASE and Global Health electronic databases were systematically searched from inception to March 2022 for observational and interventional English-language studies. Screening, data extraction and appraisals using the Joanna Briggs Institute appraisal tools were completed by two reviewers independently. Where appropriate, measures of association were converted into risk ratios (RRs) or ORs for meta-analysis. PARTICIPANTS Drivers of four-wheeled vehicles of all ages with no cognitive declines. PRIMARY AND SECONDARY OUTCOMES MVC involvement (primary) and driving cessation (secondary). RESULTS 101 studies (n=778 052) were included after full-text review. 57 studies only involved older drivers (≥65 years) and 85 were in high-income settings. Heterogeneity in the data meant that most meta-analyses were underpowered as only 25 studies, further split into different groups of eye diseases and measures of vision, could be meta-analysed. The limited evidence from the meta-analyses suggests that visual field defects (four studies; RR 1.51 (95% CI 1.23, 1.85); p<0.001; I2=46.79%), and contrast sensitivity (two studies; RR 1.40 (95% CI 1.08, 1.80); p=0.01, I2=0.11%) and visual acuity loss (five studies; RR 1.21 (95% CI 1.02, 1.43); p=0.03, I2=28.49%) may increase crash risk. The results are more inconclusive for available evidence for associations of glaucoma (five studies, RR 1.27 (95% CI 0.67, 2.42); p=0.47; I2=93.48%) and cataract (two studies RR 1.15 (95% CI 0.97, 1.36); p=0.11; I2=3.96%) with crashes. Driving cessation may also be linked with glaucoma (two studies; RR 1.62 (95% CI 1.20, 2.19); p<0.001, I2=22.45%), age-related macular degeneration (AMD) (three studies; RR 2.21 (95% CI 1.47, 3.31); p<0.001, I2=75.11%) and reduced contrast sensitivity (three studies; RR 1.30 (95% CI 1.05, 1.61); p=0.02; I2=63.19%). Cataract surgery halved MVC risk (three studies; RR 0.55 (95% CI 0.34, 0.92); p=0.02; I2=97.10). Ranibizumab injections (four randomised controlled trials) prolonged driving in persons with AMD. CONCLUSION Impaired vision identified through a variety of measures is associated with both increased MVC involvement and cessation. Cataract surgery can reduce MVC risk. Despite literature being highly heterogeneous, this review shows that detection of vision problems and appropriate treatment are critical to road safety. PROSPERO REGISTRATION NUMBER CRD42020172153.

Younger Age and Longer Case Times Associated With Emergency Department Visits After Cataract Surgery. Am J Ophthalmol 2023; 245:1-7. [PMID: 36029826 DOI: 10.1016/j.ajo.2022.08.017] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/02/2022] [Revised: 08/12/2022] [Accepted: 08/15/2022] [Indexed: 11/23/2022]
Abstract
PURPOSE To characterize the frequency, reasons, hospital costs, and risk factors for emergency department (ED) visits within 30 days of cataract surgery. DESIGN Retrospective cohort study. METHODS A retrospective review of all cataract surgeries at Duke Health between 2013 and 2021 was conducted. Demographics, case characteristics (length, complexity by billing codes, anesthesia type), ED visit findings, and hospital costs were collected. Logistic regression models were used to determine the odds of ED visits based on several risk factors. RESULTS Of 34 246 patients (57 656 eyes) undergoing cataract surgery at Duke Health from 2013 to 2021, a total of 607 patients (1.77%) had 680 ED visits within 30 days of surgery. The most common ED diagnosis was cardiovascular (24.4%), whereas ocular complaints constituted 15.4% of visits. The most common ocular diagnoses were high intraocular pressure, rebound iritis, and posterior vitreous detachment. Hospital costs were lowest for ocular diagnoses (mean $467.72) and highest for trauma diagnoses (mean $4660.55). Risk factors for ED visits included case lengths greater than 30 minutes (OR 2.1, 95% CI 1.56-2.83, P < .001), the combination of Monitored Anesthesia Care (MAC) and retrobulbar anesthesia or general anesthesia (OR 2.98, 95% CI 1.73-5.12, P < .001), and age less than 70 years (OR 1.39, 95% CI 1.16-1.65, P < .001). CONCLUSIONS ED visits within 30 days of cataract surgery are uncommon. Longer case lengths, anesthesia other than MAC alone, and younger age are associated with higher odds of ED visits.

Abstract
PURPOSE Preventive measures to mitigate the spread of coronavirus, minimized workload on health-care systems and redirected resources to COVID-19 patients resulting in a reduction of elective procedures such as cataract surgery. We report the changes in monthly cataract surgery rate and its associated determinants at a tertiary eye hospital during different periods of the pandemic. Studying the impact of COVID-19 pandemic on cataract surgery rate will help health-care policymakers to better understand the barriers to overcome the expected surgical backlog. METHODS A retrospective review of medical records was performed for cataract surgeries from November 2018 to January 2022, five thousand and ninety-two eyes that underwent cataract surgery during different phases of the COVID-19 pandemic were included. The monthly cataract surgery rate (MCSR) was calculated and compared before (Phase 1), during (Phase 2) and after the COVID-19 pandemic (Phase 3 and 4). Changes in monthly cataract surgery rate during and after the pandemic were presented as ratios and compared pre- to post-pandemic levels to evaluate the impact of different determinants. RESULTS Of 9701 cataract patients, 5092 (52.5%) were operated in P1, 71 (0.73%) in P2, 116 (1.2%) in P3 and 4422 (45.6%) in P4. The MCSR varied significantly based on the degree of visual impairment in the operated and fellow eyes, and by the type of operating surgeon (P < 0.05). Age, gender, laterality, and place of residence were not significantly different throughout the study period. During phase 1135 (2.6%) eyes had rupture of the posterior capsule (PCR), while 6 eyes (8.4%) had PCR in phase 2. CONCLUSION The monthly cataract surgery rate declined during the pandemic and has not recovered to pre-pandemic levels. This should alert the key stakeholders to address the identified barriers to surpassing the baseline monthly surgical rate as this is crucial to eliminate the surgical backlog after the pandemic.

Abstract
PURPOSE Monofocal intraocular lenses (IOLs) used in cataract surgery are designed to improve visual acuity (VA). The available evidence of new monofocal IOLs" functional benefits is limited. The aim of this meta-analysis was to analyze the improvement in VA using Tecnis Eyhance monofocal IOLs compared to standard monofocal IOLs Tecnis ZCB00. METHODS MEDLINE, Web of Science and Scopus were searched for studies assessing improvement in intermediate VA using Tecnis Eyhance IOLs versus Tecnis ZCB00 IOLs. Studies evaluating post-operative VA in patients who underwent cataract surgery were selected. This meta-analysis followed PRISMA guidelines and was registered in PROSPERO. The Cochrane Risk of Bias Tool 2.0. was used to assess the methodological quality of the included studies, risk of selection bias and comparability of cohorts and outcomes. RESULTS The search resulted in 1153 articles. Five studies met the inclusion criteria and were included in the meta-analysis. A total of 604 eyes were evaluated, of which 309 received Tecnis Eyhance IOLs and 295 were implanted with Tecnis ZCB00 IOLs. Mean binocular distant-corrected intermediate VA with Tecnis Eyhance IOLs at 2 weeks-1 month showed a significant difference of -0,21 logMAR, p < 0.001; and mean binocular distance-corrected intermediate VA with Tecnis Eyhance IOLs at 6 months showed a significant difference of -0,11 logMAR, p < 0.001. CONCLUSION Near VA could not be assessed in this meta-analysis as it was measured in very few studies. Preliminary pooled evidence indicates that intermediate VA improved with Tecnis Eyhance IOLs. Further studies evaluating near VA and with longer follow-up are still necessary.

Abstract
Purpose To assess the effectiveness of a local infection control protocol for cataract surgery (CS) during the coronavirus disease (COVID-19) pandemic and determine the trend of CSs and visual outcomes during this period, as compared to the pre-COVID-19 pandemic period. Methods This study was conducted at Suddhavej Hospital, Mahasarakham University, Mahasarakham, Thailand, between July 1, 2020, and March 31, 2021. In this two-phase study, we used only a COVID-19-screening questionnaire during the first phase and preoperative nasopharyngeal swab severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) testing for real-time reverse transcriptase-polymerase chain reaction in the second phase, during Thailand's second COVID-19 wave. Nasopharyngeal swab SARS-CoV-2 nucleic acid testing, SARS-CoV-2 IgG/IgM, or anti-SARS-CoV-2 spike antibody seroconversion was used to detect COVID-19 infection among healthcare workers. We also compared cataract surgical volume and postoperative visual acuity of CS patients between the pre-COVID-19 period and during the COVID-19 pandemic period. Results A total of 947 patients underwent CS. Thirty-two healthcare workers and 275 patients tested negative for SARS-CoV-2 in the second study phase. CSs increased on average by 50.09% month-to-month when the surgery was resumed. The mean postoperative logMAR best-corrected visual acuity was significantly better in the COVID-19 pandemic period than in the pre-pandemic period (difference, 0.1 [95% CI: 0.00-0.12], p < 0.0001). Conclusion CS could be safely performed under an infection control protocol during the COVID-19 pandemic. The cataract surgical volume, with favorable visual outcomes, has an increasing trend after resuming elective surgeries.

Abstract
PURPOSE To characterize the features of hydrophilic intraocular lenses (IOLs) important in the clinical context of expected prolonged duration time of the IOL within the eye. DESIGN Perspective. METHODS Discussion includes possible factors and mechanisms associated with hydrophilic IOLs' susceptibility to calcification and posterior capsule opacification (PCO) formation. RESULTS Results of recently reported studies show that particular surgeries, such as pars plana vitrectomy, Descemet stripping (automated) endothelial keratoplasty, and Descemet membrane endothelial keratoplasty with intraocular gas or air injection, might predispose the calcification process of hydrophilic IOLs, leading to a significant decrease in visual quality and possibly explantation of the IOL. Hydrophilic IOLs are more susceptible than hydrophobic IOLs to PCO formation, which is the most common of late postoperative complications that are associated with significant side effects. CONCLUSIONS We believe that all patients should be informed about the higher risk of calcification and PCO associated with hydrophilic IOLs. We also recommend limiting the use of hydrophilic acrylic IOLs during cataract surgery, especially when it is combined with pars plana vitrectomy or endothelial keratoplasty, and in patients with endothelial diseases who will probably require operation on it in the future.

Abstract
During the COVID-19 era, several restrictions on surgery have been imposed to reduce the infectious risk among patients and staff and further preserve the availability of critical care resources. The aim of the study was to assess their impact on the ophthalmological practice and its medico-legal implications. A retrospective review of electronic medical records of the ophthalmological departments of the University of Cagliari (SGD) and University Magna Græcia of Catanzaro (UMG), from 16 March 2020 to 14 March 2021 (52 weeks), were compared with data from the corresponding period of the previous year. Weekly data on the number and type of diagnoses and procedures performed were collected and analysed in relation to the weekly average of the total number of COVID-19 patients in intensive care units (ICUs) and inpatients in Sardinia and Calabria. Results showed a significant decrease in cataract surgery operations by 47% and 31%, respectively, in the SGD and UMG (p < 0.05) during the second semester of the year; this drop occurred at the same time as the increase in COVID-19 patients in ICU and those hospitalised in both regions. Additionally, anterior segment surgery decreased at the UMG by 30% (p < 0.05). Vitreoretinal surgery decreased by 27% at the SGD, differently increased amount 31.5% at UMG (p < 0.05). The pandemic had a dramatic impact on elective surgery in ophthalmology, quantifying the backlog is the first step in order to understanding the measures to be taken in near future.

Abstract
Vision is important for safe driving, but there is limited understanding regarding the impact of vision disorders on driving ability and safety. This systematic review evaluated and summarized evidence on the impact of vision disorders and impairment on motor vehicle crash (MVC) risk and on-road driving performance across seven databases, was prospectively registered with PROSPERO (CRD42020180135), and study quality rated using a standard tool. Forty-eight studies met the inclusion criteria for MVC risk (N = 36), on-road performance (N = 9), and both MVC risk and on-road performance (N = 3). Of these studies, less than half were rated as 'good' quality. Due to the small number of studies and often conflicting findings, it was not possible to draw firm conclusions for most vision disorders. However, evidence from several 'good' and 'fair' quality studies suggested increased MVC risk with binocular visual field impairment. There was mixed evidence regarding the impact of cataract, glaucoma, age-related macular degeneration and homonymous field loss on MVC risk and no evidence of increased MVC risk with mild VA impairment. This review highlights the need for well-designed future studies to further explore the impact of vision disorders and impairment on driving outcomes to inform evidence-based policy and fitness to drive guidelines.

Advancing the Sustainable Development Goals through improving eye health: a scoping review. Lancet Planet Health 2022; 6:e270-e280. [PMID: 35219448 DOI: 10.1016/s2542-5196(21)00351-x] [Citation(s) in RCA: 15] [Impact Index Per Article: 7.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/26/2020] [Revised: 11/30/2021] [Accepted: 12/09/2021] [Indexed: 06/14/2023]
Abstract
UN member states have committed to achieving the Sustainable Development Goals (SDGs) by 2030. This Review examines the published evidence on how improving eye health can contribute to advancing the SDGs (beyond SDG 3). We identified 29 studies that showed direct benefits from providing eye health services on SDGs related to one or more of poverty (SDGs 1, 2, and 8), education (SDG 4), equality (SDGs 5 and 10), and sustainable cities (SDG 11). The eye health services included cataract surgery, free cataract screening, provision of spectacles, trichiasis surgery, rehabilitation services, and rural community eye health volunteers. These findings provide a comprehensive perspective on the direct links between eye health services and advancing the SDGs. In addition, eye health services likely have indirect effects on multiple SDGs, mediated through one of the direct effects. Finally, there are additional plausible links to other SDGs, for which evidence has not yet been established.

Gupta S, Sutradhar R, Pequeno P, Hitzler JK, Liu N, Nathan PC. Risks of late mortality and morbidity among survivors of childhood acute leukemia with Down syndrome: A population-based cohort study. Cancer 2021; 128:1294-1301. [PMID: 34847248 DOI: 10.1002/cncr.34042] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/09/2021] [Revised: 10/15/2021] [Accepted: 11/01/2021] [Indexed: 11/10/2022]
Abstract
BACKGROUND Children with leukemia and Down syndrome (DS) are at higher risk of acute treatment toxicities than those without DS. Whether late toxicity risks are also elevated is unknown. METHODS The authors identified all patients diagnosed with leukemia before the age of 18 years in Ontario, Canada between 1987 and 2013 and who survived greater than 5 years since their last pediatric cancer event. Survivors were divided into those with and without DS, matched by birth year, sex, leukemia type, and receipt of radiation. DS survivors were matched to individuals with DS without childhood cancer (DS controls) in a 1:10 ratio. Outcomes were identified through linkage to population-based health services databases. RESULTS DS survivors (n = 79) experienced inferior overall survival compared to non-DS survivors (n = 231) (20-year overall survival, 81.7% ± 6.8% vs 98.3% ± 1.2%; hazard ratio [HR], 12.8; P < .0001) and to DS controls (n = 790; 96.3% ± 1.2%; HR, 5.4 P < .0001). Pulmonary and infectious deaths were noted among DS survivors. There was no difference in the incidence of congestive heart failure between DS survivors and either control cohort, nor of hearing loss or dementia between DS survivors and DS controls. CONCLUSIONS DS survivors were at substantially higher risk of late mortality than non-DS survivors or DS controls. This excess risk was not attributable to cardiac- or subsequent malignant neoplasm-related late effects, historically main causes of premature death among non-DS survivors. Chronic morbidities associated with DS were not increased compared to DS controls. DS-specific surveillance guidelines may be warranted.

Risks of Serious Injury with Testosterone Treatment. Am J Med 2021; 134:84-94.e6. [PMID: 32926849 DOI: 10.1016/j.amjmed.2020.07.037] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/14/2019] [Revised: 07/31/2020] [Accepted: 07/31/2020] [Indexed: 11/24/2022]
Abstract
BACKGROUND Injury causes significant morbidity and mortality that is sometimes attributed to testosterone and violence. We hypothesized that prescribed testosterone might be associated with the subsequent risk of serious injury. METHODS We conducted a self-matched individual-patient exposure-crossover analysis comparing injury risks before and after initiation of testosterone. We selected adults treated with testosterone in Ontario, Canada, from October 1, 2012, to October 1, 2017 (enrollment) and continued until October 1, 2018 (follow-up). The primary outcome was defined as an acute traumatic event that required emergency medical care. RESULTS A total of 64,386 patients were treated with testosterone of whom 89% were men with a median age of 52 years. We identified 34,439 serious injuries during the baseline interval before starting testosterone (584 per month) and 7349 serious injuries during the subsequent interval after starting testosterone (565 per month). Rates of injuries were substantially above the population norm in both intervals with no significant increased risk after starting testosterone (relative risk = 1.00; 95% confidence interval: 0.96-1.04, P = 0.850). The unchanged risk extended to diverse patients, was observed for different formulations and applied to all injury mechanisms. In contrast, testosterone treatment was associated with a 48% increased risk of a thromboembolic event (relative risk = 1.48; 95% confidence interval: 1.25-1.74, P < 0.001). CONCLUSIONS Testosterone treatment was associated with a substantial baseline risk of serious injury that did not increase further after starting therapy. Physicians prescribing testosterone could consider basic safety reminders to mitigate injury risks.

Abstract
BACKGROUND Insurance coverage may reduce cost barriers to obtain vision correction. Our aim was to determine the frequency and source of prescription eyewear insurance to understand how Canadians finance optical correction. METHODS We conducted a repeated population-based cross-sectional study using 2003, 2005 and 2013-2014 Canadian Community Health Survey data from respondents aged 12 years or older from Ontario, Canada. In this group, the cost of prescription eyewear is not covered by the government unless one is registered with a social assistance program or belongs to a specific population. We determined the frequency and source of insurance coverage for prescription eyewear in proportions. We used survey weights provided by Statistics Canada in all analyses to account for sample selection, a complex survey, and adjustments for seasonal effect, poststratification, nonresponse and calibration. We compared unadjusted proportions and adjusted prevalence ratios (PRs) of having insurance. RESULTS Insurance covered all or part of the costs of prescription eyewear for 62% of Ontarians in all 3 survey years. Of those insured, 84.1%-86.0% had employer-sponsored coverage, 9.0%-10.3% had government-sponsored coverage, and 5.7%-6.8% had private plans. Employer-sponsored coverage remained constant for those in households with postsecondary graduation but decreased significantly for those in households with less than secondary school graduation, from 67.0% (95% confidence interval [CI] 63.2%-70.8%) (n = 175 000) in 2005 to 54.6% (95% CI 50.1%-59.2%) (n = 123 500) in 2013-2014. Government-sponsored coverage increased significantly for those in households with less than secondary school graduation, from 29.2% (95% CI 25.5%-32.9%) (n = 76 400) in 2005 to 41.7% (95% CI 37.2%-46.1%) (n = 93 900) in 2013-2014. In 2013-2014, Ontarians in households with less than secondary school graduation were less likely than those with secondary school graduation to report employer-sponsored coverage (adjusted PR 0.79, 95% CI 0.75-0.84) but were more likely to have government-sponsored coverage (adjusted PR 1.27, 95% CI 1.06-1.53). INTERPRETATION Sixty-two percent of Ontarians had prescription eyewear insurance in 2003, 2005 and 2013-2014; the largest source of insurance was employers, primarily covering those with higher education levels, whereas government-sponsored insurance increased significantly among those with lower education levels. Further research is needed to elucidate barriers to obtaining prescription eyewear and the degree to which affordability impairs access to vision correction.

Association between conventional or blue-light-filtering intraocular lenses and survival in bilateral cataract surgery patients. iScience 2020; 24:102009. [PMID: 33490917 PMCID: PMC7809500 DOI: 10.1016/j.isci.2020.102009] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/10/2020] [Revised: 12/17/2020] [Accepted: 12/23/2020] [Indexed: 11/24/2022] Open
Abstract
Circadian rhythms regulate adaptive alterations in mammalian physiology and are maximally entrained by the short wavelength blue spectrum; cataracts block the transmission of light, particularly blue light. Cataract surgery is performed with two types of intraocular lenses (IOL): (1) conventional IOL that transmit the entire visible spectrum and (2) blue-light-filtering (BF) IOL that block the short wavelength blue spectrum. We hypothesized that the transmission properties of IOL are associated with long-term survival. This retrospective cohort study of a 15-hospital healthcare system identified 9,108 participants who underwent bilateral cataract surgery; 3,087 were implanted with conventional IOL and 6,021 received BF-IOL. Multivariable Cox proportional hazards models that included several a priori determined subgroup and sensitivity analyses yielded estimates supporting that conventional IOL compared with BF-IOL may be associated with significantly reduced risk of long-term death. Confirming these differences and identifying any potential causal mechanisms await the conduct of appropriately controlled prospective translational trials.

Abstract
Suspension of elective surgical care during COVID-19 will result in a large backlog of cataract surgeries in Medicare beneficiaries. It is necessary to start planning proactively to reduce the backlog. Purpose: To forecast the volume of cataract surgery in Medicare beneficiaries in the United States in 2020 and to estimate the surgical backlog that may be created due to COVID-19. Design: Epidemiologic modeling. Methods: Baseline trends in cataract surgery among Medicare beneficiaries were assessed by querying the Medicare Part B Provider Utilization National Summary data. It was assumed that once the surgical deferment is over, there will be a ramp-up period; this was modeled using a stochastic Monte Carlo simulation. Total surgical backlog 2 years postsuspension was estimated. Sensitivity analyses were used to test model assumptions. Results: Assuming cataract surgeries were to resume in May 2020, it would take 4 months under an optimistic scenario to revert to 90% of the expected pre-COVID forecasted volume. At 2-year postsuspension, the resulting backlog would be between 1.1 and 1.6 million cases. Sensitivity analyses revealed that a substantial surgical backlog would remain despite potentially lower surgical demand in the future. Conclusions: Suspension of elective cataract surgical care during the COVID-19 surge might have a lasting impact on ophthalmology and will likely result in a cataract surgical patient backlog. These data may aid physicians, payers, and policymakers in planning for postpandemic recovery.

Abstract
PURPOSE Most patients report being highly satisfied with the outcome of cataract surgery but there are variable reports regarding the impact of cataract surgery on some real-world activities, such as fall rates. We hypothesised that adaptations to changed refractive correction and visual function may cause difficulties in undertaking everyday activities for some patients and used a series of focus groups to explore this issue. METHOD Qualitative methods were used to explore patients' experiences of their vision following cataract surgery, including adaptation to vision changes and their post-surgical spectacle prescription. Twenty-six participants took part in five focus groups (Mean age = 68.2 ± 11.4 years), and the data were analysed using thematic analysis. RESULTS We identified three themes. 'Changes to Vision' explores participants' adaptation following cataract surgery. While several had problems with tasks relying on binocular vision, few found them bothersome and they resolved following second eye surgery. Participants described a trial and error approach to solving these problems rather than applying solutions suggested by their eyecare professionals. 'Prescription Restrictions' describes the long-term vision problems that pre-surgery myopic patients experienced as a consequence of becoming emmetropic following surgery and thus needing spectacles for reading and other close work activities, which they did not need before surgery. Very few reported that they had the information or time to make a decision regarding their post-operative correction. 'Information Needs' describes participant's responses to the post-surgical information they were given, and the unmet information need regarding when they can drive following surgery. CONCLUSION The findings highlight the need for clinicians to provide information on adaptation effects, assist patients to select the refractive outcome that best suits their lifestyle, and provide clear advice about when patients can start driving again. Patients need to be provided with better guidance from clinicians and prescribing guidelines for clinicians would be beneficial, particularly for the period between first- and second-eye surgery.

Abstract
An ageing population has led to a substantial increase in the prevalence of visual impairments, which can compromise lifestyle, health and general physical and psychological well-being. Age-related cataracts can have a negative effect on older people's quality of life but can be corrected by surgery. It is imperative that older people have access to cataract surgery and, given government objectives of NHS efficiency gains, advanced level nurse practitioners have the potential to increase capacity for and access to cataract surgery. This article outlines the aetiology of cataracts, developments in ophthalmic nursing and the broadened scope of practice of advanced ophthalmic nurse practitioners (AONPs). It explores how the AONP is well-placed to provide high quality care to the older person who requires cataract surgery. Professional drivers for role development are explored in relation to older people.
