Abstract
PURPOSE To update the literature on peripheral optics and vision following intraocular lens (IOLs) implantation. METHODS We investigated how current IOLs influence peripheral visual function, peripheral optical quality, and visual perception and performance, in patients following cataract surgery. Peripheral vision is described as vision outside the central foveal region of the eye (beyond 4-5° of eccentricity). We systematically searched PubMed, Cochrane Central Register of Controlled Trials, Embase, and gray literature for relevant references. Randomized controlled trials and observational studies were eligible for inclusion. Finally, 47 studies with a total of 5963 participants were eligible for this review, of which 15 were included in the meta-analysis. RESULTS Regarding visual fields, the meta-analysis showed that the pooled estimate of mean deviation (MD) measured with perimetry tests (standard automated perimetry [SAP], short-wavelength automated perimetry [SWAP], and frequency doubling technology [FDT]) appears to be lower than the mean of healthy age-matched controls, regardless of IOL design. Results for pooled estimate show that localized defects (pattern standard deviation [PSD]) were higher than those in the healthy age-matched controls for FDT. We also collected evidence demonstrating that pseudophakia increases peripheral astigmatism and a myopic shift from 20° onward, leading to decreased peripheral image quality compared with that in phakic eyes. Patient-reported outcomes on peripheral vision showed a pooled score estimate of 95.19, indicating high satisfaction, and for the Steps & Stairs questions, a pooled score estimate at 0.23, indicating no to little difficulty seeing steps and stairs. CONCLUSIONS Peripheral image quality is degraded in eyes after cataract surgery. Nevertheless, whether this degradation leads to impaired visual function in the periphery requires further investigation.

Health economic evaluation of a nurse-assisted online eye screening in home healthcare to reduce avoidable vision impairment (iScreen): study protocol for a cluster randomized controlled trial. Trials 2024; 25:102. [PMID: 38308377 PMCID: PMC10835833 DOI: 10.1186/s13063-023-07882-0] [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: 10/06/2023] [Accepted: 12/15/2023] [Indexed: 02/04/2024] Open
Abstract
BACKGROUND Among older people undiagnosed and untreated vision impairment and blindness are common. The leading causes are uncorrected refractive errors and cataracts. Vision problems are associated with a lower quality of life, several health problems, and a higher chance of falling accidents and fractures. To eliminate avoidable vision impairment and blindness, targeted eye screening programs are recommended. Older patients, receiving home healthcare, have not yet been considered as a population at risk who could benefit from eye screening. METHODS A cluster-randomized controlled trial will be conducted to investigate the cost-effectiveness and cost-utility of online nurse-assisted eye screening in home healthcare, compared to care as usual, in reducing avoidable vision impairment. A healthcare and societal perspective will be used. The study will be performed in collaboration with several home healthcare organizations in the Netherlands. The online eye screening consists of near and distance visual acuity, followed by an Amsler grading test. Measurements in both groups will take place at baseline and after 6 and 12 months of follow-up. A total of 240 participants will be recruited. Older men and women (65 +), who receive home-based nursing and are cognitively able to participate, will be included. The primary outcome will be the change of two lines or more on the Colenbrander-1 M visual acuity chart between baseline and 12-month follow-up. DISCUSSION An eye screening for populations at risk contributes to the detection of undiagnosed and untreated vision impairment. This may reduce the health-related consequences of vision loss and the high economic burden associated with vision impairment. TRIAL REGISTRATION ClinicalTrials.gov NCT06058637. Registered on 27 September 2023.

Abstract
OBJECTIVE To compare the incidence of falls between patients with visually significant cataracts in both eyes and those who have undergone first-eye cataract surgery. METHODS This retrospective case-control study involved patients with a history of cataracts in both eyes who had undergone first-eye cataract surgery within the past 9 to 12 months (pseudophakic group). The control group comprised patients with cataracts in both eyes (cataract group). We assessed best-corrected visual acuity (BCVA), systemic comorbidities and medications (using the Charlson comorbidity index), and independent daily activities (using the Lawton Instrumental Activities of Daily Living scale). The patients were questioned about experiencing two or more falls in the last 6 months. RESULTS Each group comprised 50 patients. Binocular BCVA was significantly better in the pseudophakic group (0.05 ± 0.06 logMAR) than in the cataract group (0.77 ± 0.34 logMAR). Of all participants, 22% reported experiencing two or more falls in the last 6 months. Multivariate analysis demonstrated significantly better BCVA in participants with less than two falls. CONCLUSIONS Patients of advanced age with visually significant cataracts in both eyes are at a higher risk of falling. First-eye cataract surgery may mitigate the occurrence of falls by improving binocular BCVA.

Abstract
OBJECTIVE Vision changes can precipitate falls in the elderly resulting in significant morbidity and mortality. We hypothesized that pseudophakic monovision and ensuing anisometropia and aniseikonia impact elderly fall risk. This study assessed fall risk in patients with pseudophakic monovision, pseudophakic single vision distance (classic cataract surgery), and cataracts with no surgery. DESIGN Retrospective single-institution cohort study PARTICIPANTS: Patients with bilateral cataracts diagnosed at 60 years of age or older who underwent bilateral cataract surgery (monovision or single vision distance) or did not undergo any cataract surgery (n = 13 385). Patients with unilateral surgery or a fall prior to cataract diagnosis were excluded. METHODS Data were obtained from the Stanford Research Repository. Time-to-fall analysis was performed across all 3 groups. Primary outcome was hazard ratio (HR) for fall after second eye cataract surgery or after bilateral cataract diagnosis. RESULTS Of 13 385 patients (241 pseudophakic monovision, 2809 pseudophakic single vision, 10 335 no surgery), 850 fell after cataract diagnosis. Pseudophakic monovision was not associated with fall risk after controlling for age, sex, and myopia. Pseudophakic single-vision patients had a decreased time to fall compared with no-surgery patients (log rank, p < 0.001). Older age at cataract diagnosis (HR =1.05, 95% confidence interval [CI] 1.04-1.06, p < 0.001) or at time of surgery (HR = 1.05, 95% CI 1.03-1.07, p < 0.001) increased fall risk, as did female sex (HR = 1.29, 95% CI 1.10-1.51, p = 0.002) and preexisting myopia (HR = 1.31, 95% CI 1.01-1.71, p = 0.046) among nonsurgical patients. CONCLUSIONS Pseudophakic monovision did not impact fall risk, but pseudophakic single vision may increase falls compared with patients without cataract surgery.

Abstract
IMPORTANCE Blue light-filtering (BLF) intraocular lenses (IOLs) have been widely used in clinical practice for more than 20 years and have been implanted in millions of patients with cataracts worldwide. However, little evidence on the association of BLF IOLs with injuries is available. OBJECTIVE To assess the association of BLF IOLs with all-cause and traffic accident-related injuries and quality of vision while driving after bilateral cataract surgery. DESIGN, SETTING, AND PARTICIPANTS This retrospective registry-based cohort study included patients who underwent bilateral cataract surgery between September 3, 2007, and December 14, 2018, and were followed until December 14, 2021. Surgery was performed at the Department of Ophthalmology, Kymenlaakso Central Hospital, Kotka, Finland. The 4986 participants received non-BLF IOLs (n = 2609) or BLF IOLs (n = 2377) in both eyes. Patients undergoing bilateral surgery between 2015 to 2016 with non-BLF IOLs (n = 102) or BLF IOLs (n = 91) and currently driving a car were interviewed using a structured questionnaire for visual performance while driving. EXPOSURES Follow-up for a mean (SD) of 2166 (1110) days after second eye surgery. MAIN OUTCOMES AND MEASURES Kaplan-Meier and multivariable Cox proportional hazards regression analyses for the risk of all-cause and traffic accident-related injuries after surgery in the second eye obtained from the patient medical records were assessed. To improve follow-up precision, both death and the end of the follow-up were used as censoring events. RESULTS A total of 4986 patients were included in the analysis (1707 [34.2%] men and 3279 [65.8%] women; mean [SD] age, 73.2 [8.6] years at the first surgery and 74.3 [8.8] years at the second). Injury-free survival rates preceding the first eye surgery were comparable between the non-BLF and BLF IOL groups (hazard ratio adjusted for age and sex, 0.95 [95% CI, 0.81-1.13; P = .57]). In multivariable Cox proportional hazards regression analysis controlling for age and sex, the use of BLF IOLs showed no advantage in overall injuries compared with the use of non-BLF IOLs (hazard ratio, 0.99 [95% CI, 0.88-1.11]; P = .85) or in any injury subtype. Subjective visual performance parameters for driving were all comparable between the non-BLF and BLF IOL groups except for glare when driving in the dark (evening or night), which occurred among 9 of 80 patients with BLF IOLs compared with 0 of 83 non-BLF IOLs (P < .001). CONCLUSIONS AND RELEVANCE The findings of this cohort study suggest that use of BLF IOLs was not associated with reduced risk of injuries, whereas glare during nighttime driving was significantly worse in the BLF IOL group with pseudophakia.

Abstract
PURPOSE To evaluate peripheral refraction and contrast detection sensitivity in pseudophakic patients implanted with a new type of inverted meniscus intraocular lens (IOL) (Art25; Voptica SL) that was designed to provide better peripheral optics. METHODS One month after cataract surgery, in 87 eyes implanted with the Art25 IOL, peripheral contrast detection sensitivity was measured psychophysically at 40° visual angle, both horizontally and vertically, and compared with a control group of 51 eyes implanted with standard biconvex IOLs. Thirty-one eyes with the Art25 IOL and 28 eyes from the control group were randomly selected to also measure peripheral refraction using a scanning Hartmann-Shack wavefront sensor along 80° in the horizontal meridian. RESULTS Most patients achieved emmetropia and good visual acuity, and no significant adverse events were observed after cataract surgery with Art25 IOLs. Peripheral contrast detection sensitivity was significantly better (P < .01) in the group with the Art25 IOL in both directions (7.78 ± 3.24 vs 5.74 ± 2.60 vertical, 10.98 ± 5.09 vs 7.47 ± 3.96 horizontal), which was in agreement with the optical quality improvement in the periphery due to a reduction of defocus (1.97 and 1.21 diopters [D] at 40° temporal and nasal sides) and astigmatism (1.17 and 0.37 D at 40° temporal and nasal sides) that was statistically significant (P < .01) from 20° of eccentricity. CONCLUSIONS Patients implanted with a new inverted meniscus IOL present a reduced amount of peripheral defocus and astigmatism compared to patients implanted with standard biconvex IOLs. This improvement in optical quality leads to better contrast detection sensitivity measured at 40° of eccentricity. [J Refract Surg. 2022;38(4):229-234.].

Abstract
Elderly patients who underwent cataract surgery showed lower prevalence and cumulative incidence rates of hip and vertebral fragility fractures than those who did not. Therefore, cataract surgery in elderly patients may reduce the incidence of hip and vertebral fragility fractures. PURPOSE The purpose of this study was to compare the incidence rates of hip and vertebral fragility fractures between patients who underwent cataract surgery and those who did not, and to investigate the effect of cataract surgery on the incidence of fragility fracture in elderly population using nationwide claims data. METHODS A total of 558,147 participants from the National Health Insurance Service - Senior cohort were included. The participants were set into the hip fracture group (507,651) and vertebral fracture group (507,899) depending on the type of fracture. RESULTS The number of hip fractures that occurred in the non-cataract surgery (NC) group was 36,971 (9.9%), while 8850 (6.6%) hip fractures occurred in the cataract surgery (C) group. The number of vertebral fractures that occurred in the NC group was 38,689 (10.3%), while 10,112 (7.6%) vertebral fractures occurred in the C group (all p < .001). The hazard ratios of hip and vertebral fractures were 0.58 and 0.60 for the total population that had undergone cataract surgery (all p < .001). The cumulative incidence rates of both fractures in the cataract surgery group were significantly lower than those in the non-cataract surgery group during 10 years (all p < .0001). CONCLUSION Elderly patients who underwent cataract surgery showed a lower prevalence of hip and vertebral fragility fractures than those who did not. In addition, the cumulative incidence rates of both fractures in the cataract surgery group were lower than those in the non-cataract surgery group. Therefore, cataract surgery in elderly patients may reduce the incidence of hip and vertebral fragility fractures.

Abstract
OBJECTIVE To investigate macular vascular changes and underlying influencing factors using optical coherence tomography angiography (OCTA) after phacoemulsification in patients with cataracts. METHODS Patients diagnosed with cataracts at the First Affiliated Hospital of Anhui Medical University from March to September 2019 were included. The macular retinal thickness, the microvascular density in the foveal, parafoveal, and perifoveal area, and the area of the foveal avascular zone (FAZ) were measured using OCTA at baseline, 1-week, 1-month, and 3-month post-operation. RESULTS Forty-seven cataract patients (58 eyes) were eligible for this study. Compared with baseline thickness, the foveal, parafoveal, and perifoveal thicknesses, particularly in the inner retina, significantly increased at 1- and 3-month post-operation (P<0.05). There was a nonsignificant difference in the microvascular density of the foveal and perifoveal areas at 1-week, 1-month, and 3-month post-operation (P>0.05). At 1-month post-operation, the deep vessel density at the perifovea significantly increased (P<0.05). The FAZ area significantly diminished at 1- and 3-month post-operation compared with the baseline data (P<0.05). CONCLUSION Phacoemulsification offers a satisfactory efficacy response, with an increased macular thickness, reduced FAZ area, and nonsignificant changes in the microvascular density at the perifovea after surgery.

Effect of Cataract Surgery on Frequency of Falls among Older Persons: A Systematic Review and Meta-Analysis. J Ophthalmol 2021; 2021:2169571. [PMID: 33815834 PMCID: PMC7987466 DOI: 10.1155/2021/2169571] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/26/2020] [Revised: 03/04/2021] [Accepted: 03/06/2021] [Indexed: 11/17/2022] Open
Abstract
Background Falls are a significant public health problem among older people worldwide. The aim was to perform a new systematic review and meta-analysis to assess whether cataract surgery is effective in reducing the rate of falls in older persons. Methods The systematic review was performed following the recommendations by the Cochrane Collaboration. Original papers were included with RCT or quasi-experimental design, which described the effect on uni- or bilateral cataract surgery on the rate of falls among people aged 60 or older. Titles and abstracts were reviewed, full-text versions were retrieved, and two independent examiners reviewed them to assess inclusion criteria. All relevant variables were synthesised in an evidence table. Random-effects meta-analyses were performed pooling the trials, and results were expressed as relative risk (RR) and 95% confidence intervals. Results The initial search reported 99 potential abstracts, and 41 full-text versions were examined. In the end, eight studies were included. Five included patients 65 years of age and older, two patients 55 years and older, and one included patients 50 years or older. Phacoemulsification and intraocular lens implant were performed in all studies. Two were RCT, and six were quasi-experimental. Falls was the main outcome. The six quasi-experimental studies reported that a reduction in the frequency of falls was observed (RR 0.68, 95% CI 0.48-0.96), although heterogeneity was significant (I 2 = 74%). Only one RCT reported risk reduction of 34% (RR 0.66, 95% CI 0.45-0.96). Conclusions This meta-analysis provides evidence that the first cataract surgery reduces the frequency of falls in older people with bilateral cataracts, but a second surgery does not have significant impact.

Changes in patient subjective happiness and satisfaction with cataract surgery. Sci Rep 2020; 10:17273. [PMID: 33057036 PMCID: PMC7560890 DOI: 10.1038/s41598-020-72846-2] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/12/2019] [Accepted: 06/25/2020] [Indexed: 11/15/2022] Open
Abstract
The purpose of this study was to investigate the changes in patient subjective happiness and satisfaction with cataract surgery and evaluate the association between satisfaction and types of cataract. This study surveyed 247 participants (mean age, 67.9 years) and they completed questionnaires on their satisfaction with the surgery, the subjective happiness scale (SHS) and the Pittsburgh Sleep Quality Index (PSQI) before and after surgery. The SHS increased postoperatively from 4.6 ± 0.7 to 4.8 ± 0.7 (P = 0.007) and 83.4% of patients were satisfied with the surgical results and the average satisfaction score was 4.2 out of a possible 5.0. Multiple regression analysis showed that patient satisfaction was significantly associated with the postoperative SHS (β = 0.380; P < 0.001), the postoperative PSQI (β = −0.041; P = 0.035) and the presence of a posterior subcapsular cataract (PSC) (β = 0.277; P = 0.026). This study clarified that cataract surgery may improve both visual function and patient happiness and that patient satisfaction was affected by postoperative sleep quality and the disappearance of a PSC.

Abstract
We evaluated the prevalence of falls and their association with visual impairment (VI) in elderly residents in 'homes for the aged' in Hyderabad, India. Participants aged ≥ 60 years were recruited from 41 homes, and a comprehensive eye examination was conducted. Interviews were conducted to collect personal and demographic information, systemic health status, fear of falling, depression, and history of falls in the last year. VI categories included low vision (presenting visual acuity worse than 6/18 to 3/60) and blindness (presenting visual acuity worse than 3/60). The data of 1,074 participants were analysed. The mean age was 74.4 years (standard deviation:8.7 years); 63.9% were women, 19.4% had no formal education, 28.1% were diabetic and 56.9% were hypertensive. The annual prevalence of falls was 29.1% (95% CI: 26.4-32.0). Multivariable analysis showed those with VI had significantly higher odds of falls (Odds Ratio:1.47; p = 0.043). The prevalence of falls was higher among those with VI due to uncorrected refractive errors. We found a very high prevalence of falls in elderly individuals living in 'homes for the aged' in Hyderabad, India. Addressing VI can result in fewer falls and contribute to healthy aging in India.

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
PURPOSE To investigate the impact of the type of the intraocular lenses (IOLs) in first-eye cataract surgery in elderly people on the risk of hospitalisation due to falls and injuries. METHODS A retrospective cohort study was conducted using the Australian Government Department Veterans' Affairs claims data. All people aged 65 years and above who had first cataract surgery between January 2007 and July 2017 were identified. Two cohorts were established depending on the type of IOL-monofocal and multifocal. The risk of injuries and falls requiring hospitalisation in the first 3 months post the surgery was assessed using Cox proportional hazard models with age at entry as primary time scale and adjusting for gender, comorbidities and prior history of falls. RESULTS There were 45 728 people across the two cohorts with the majority receiving monofocal lenses (97%), followed by multifocal lenses (3%) at the time of first cataract surgery. The risk of injury and falls was lower (but not significant) in the multifocal cohort compared to monofocal cohort (adjusted hazard ratio (aHR) 0.56, 95% CI 0.26-1.17). The risk was also lower (but not significant) when stratifying by age group at the time of the surgery. CONCLUSIONS Regardless of age, multifocal lenses did not appear to be associated with the higher risk of serious injuries and falls after first-eye cataract surgery compared to monofocal lenses.

Abstract
Objectives: To investigate the impact of phacoemulsification surgery and intraocular lens implantation on the functional balance skills of adults. Materials and Methods: This prospective study included patients with cataract who were recommended phacoemulsification surgery and intraocular lens implantation between May and October 2016. The Berg Balance Scale and Tinetti Gait and Balance Test were performed by a physical therapy specialist before and 1 month after surgery. Patients were analyzed in terms of age, visual acuity, and balance. Balance scores before and after cataract surgery were compared. We also compared patients with high (≤2 LogMAR) and low (>2 LogMAR) visual acuity. P values below 0.05 were accepted as statistically significant. Results: Fifty-one patients (27 female and 24 male, mean age 66.96 years) were included in the study. One month after surgery, the patients’ Berg Balance scores and Tinetti Gait and Balance scores were increased by 3.60±5.00% and 4.14±6.55%, respectively. Postoperative increase in visual acuity was significantly greater in the 16 patients with visual acuity less than 0.05 (>2 LogMAR) (p=0.036), but balance scores were not significantly different. Conclusion: Visual acuity is significantly improved one month after cataract surgery, which also leads to significant increases in low functional balance scores among patients with poorer vision. The rapid increase in vision after cataract surgery enhances balance skills, resulting in safer mobility and increased quality of life.

Abstract
Importance Trustworthy clinical practice guidelines require reliable systematic reviews of the evidence to support recommendations. Since 2016, the American Academy of Ophthalmology (AAO) has partnered with Cochrane Eyes and Vision US Satellite to update their guidelines, the Preferred Practice Patterns (PPP). Objective To describe experiences and findings related to identifying reliable systematic reviews that support topics likely to be addressed in the 2016 update of the 2011 AAO PPP guidelines on cataract in the adult eye. Design, Setting, and Participants Cross-sectional study. Systematic reviews on the management of cataract were searched for in an established database. Each relevant systematic review was mapped to 1 or more of the 24 management categories listed under the Management section of the table of contents of the 2011 AAO PPP guidelines. Data were extracted to determine the reliability of each systematic review using prespecified criteria, and the reliable systematic reviews were examined to find whether they were referenced in the 2016 AAO PPP guidelines. For comparison, we assessed whether the reliable systematic reviews published before February 2010 the last search date of the 2011 AAO PPP guidelines were referenced in the 2011 AAO PPP guidelines. Cochrane Eyes and Vision US Satellite did not provide systematic reviews to the AAO during the development of the 2011 AAO PPP guidelines. Main Outcomes and Measures Systematic review reliability was defined by reporting eligibility criteria, performing a comprehensive literature search, assessing methodologic quality of included studies, using appropriate methods for meta-analysis, and basing conclusions on review findings. Results From 99 systematic reviews on management of cataract, 46 (46%) were classified as reliable. No evidence that a comprehensive search had been conducted was the most common reason a review was classified as unreliable. All 46 reliable systematic reviews were cited in the 2016 AAO PPP guidelines, and 8 of 15 available reliable reviews (53%) were cited in the 2011 PPP guidelines. Conclusions and Relevance The partnership between Cochrane Eyes and Vision US Satellite and the AAO provides the AAO access to an evidence base of relevant and reliable systematic reviews, thereby supporting robust and efficient clinical practice guidelines development to improve the quality of eye care.

Abstract
The aim of the present study was to evaluate factors associated with falls in community-dwelling older adults diagnosed with cataracts. An analytical, cross-sectional study was conducted with a sample of community-dwelling older adults residing in the Federal District of Brazil. Interviews and assessment tools were administered, such as the Timed Up and Go test, Short Physical Performance Battery (SPPB), Biodex Balance System, Katz Index, Lawton Scale, Minnesota Leisure Time Physical Activity Questionnaire and Mini Mental State Examination. Statistical analysis involved binary logistic regression. One hundred forty-two older adults (85 with cataracts) participated in the study (mean age: 69.39 ± 5.67 years). Falls were associated with the female sex (OR: 4.45) and sub-maximum score on the SPPB (OR: 3.53) among patients with cataracts, whereas multimorbidity (OR: 5.10) was the risk factor risk for older adults without cataracts. The data suggest different risk factors for falls among older adults diagnosed with cataracts.

Abstract
Purpose The purpose of this study was to investigate the impact of the first and second eye cataract surgeries on the risk of falls in participants with bilateral cataract and to determine which changes in visual measures are associated with changes in the number of falls throughout the cataract surgery process. Patients and methods Fifty-five older adults with bilateral cataract aged 55+ years were assessed at three time points during the cataract surgery process, and they completed a falls diary. Two separate generalized estimating equation-negative binomial models were undertaken to assess changes in the number of falls before first eye cataract surgery, between first and second eye surgeries, and after second eye cataract surgery and which changes in visual measures were associated with changes in the number of falls. Results After adjusting for potential confounding factors, the risk of falls decreased by 54% (incidence rate ratio (IRR) =0.458, 95% CI=0.215-0.974, p=0.04) after first eye cataract surgery only, compared with the period before first eye surgery. The risk of falls decreased by 73% (IRR =0.268, 95% CI =0.114-0.628, p=0.002) after second eye cataract surgery, compared with the period before first eye surgery. Improved binocular visual acuity (IRR =5.488, 95% CI =1.191-25.282, p=0.029) and contrast sensitivity (IRR =0.257, 95% CI =0.070-0.939, p=0.040) were associated with a decrease in the number of falls. Conclusion The study found that first and second eye cataract surgeries reduced the risk of falls among a cohort of bilateral cataract patients with relatively good baseline vision. This suggests that timely first and second eye cataract surgeries could play an important role in reducing the burden due to falls among older adults with cataract.

Abstract
Background Fall episodes are not unusual among community residents, especially the elderly, and lower muscle strength is an important issue to address in order to prevent falls. Methods A community health survey was conducted in a suburban area of Taiwan, and 1067 older adults were selected for enrollment in the present study. All the enrolled subjects had been visited at their homes; the subjects’ strength of both hands and muscle mass of both legs were measured and well-established questionnaires were finished by certificated paramedic staffs. Results The incidence of fall episodes in the previous 1 year in the Yilan elderly population was 15.1%, and the female predominance was significant. A significantly higher prevalence of cataracts was found in group who experienced a fall in the past year (64% vs. 54.9% in the non-fall group). Mild or more severe dementia was much more prevalent in the group who experienced a recent fall (33.8% vs. 25.7% in the non-fall group). The strength of both hands tested as the physical function was 17.6 ± 8.0 kg in the recent fall group, significantly weaker than that in the non-fall group (20.7 ± 8.7 kg). Multivariate regression analysis revealed a greater weekly exercise duration and greater strength of both hands reduced the occurrence of falls among the whole and the female population. The standardized effect sizes of hand grip strength between both groups, not trivial, were 0.29 and 0.37 for the total population and the female subpopulation respectively. Conclusions Less weekly exercise duration and weaker muscle strength were f ound to be independent risk factors of fall episode(s) in an elderly Taiwanese population, especially in the female sub-population. Muscle strength, measured by average of both hands grip strength, was the most significantly factor of one-year fall episode(s) accessed retrospectively.

Abstract
The aim of this study was to determine the presence of prior cataract surgery and best-corrected visual acuity (BCVA) in an elderly Japanese cohort. The Fujiwara-kyo Eye Study was a prospective, population-based, cross-sectional epidemiological study. The subjects were ≥68 years who lived in the Nara Prefecture and responded to recruitment notices. All of the subjects underwent comprehensive ophthalmological examinations, and the sociodemographic information and medical history, including prior cataract surgery, were obtained by answers to a questionnaire. The associations between the BCVA, age, sex, and history of cataract surgery were determined. A total of 2,873 subjects whose mean age was 76.3 ± 4.9 (mean ± standard deviation) years were studied. The mean BCVA was −0.020 ± 0.14 logarithm of the minimum angle of resolution units, and it was significantly better in the group with education ≥13 years (p < 0.01). Overall, 24.2% of the subjects had undergone cataract surgery, and 41.7% of the subjects ≥80 years had undergone cataract surgery. The incidence of prior cataract surgery increased with increasing age (p < 0.001 for trend). The mean BCVA of eyes with cataract surgery was significantly better than that of eyes without cataract surgery in subjects ≥80 years (p < 0.01). Visual acuity was generally good in this cohort of elderly Japanese subjects. In this cohort, 24.2% of the subjects had undergone cataract surgery, and the subjects ≥80 years had better BCVA than those without cataract surgery.

Effectiveness of Non-Pharmacological Interventions to Prevent Falls in Older People: A Systematic Overview. The SENATOR Project ONTOP Series. PLoS One 2016; 11:e0161579. [PMID: 27559744 PMCID: PMC4999091 DOI: 10.1371/journal.pone.0161579] [Citation(s) in RCA: 29] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/08/2016] [Accepted: 08/08/2016] [Indexed: 01/08/2023] Open
Abstract
BACKGROUND Falls are common events in older people, which cause considerable morbidity and mortality. Non-pharmacological interventions are an important approach to prevent falls. There are a large number of systematic reviews of non-pharmacological interventions, whose evidence needs to be synthesized in order to facilitate evidence-based clinical decision making. OBJECTIVES To systematically examine reviews and meta-analyses that evaluated non-pharmacological interventions to prevent falls in older adults in the community, care facilities and hospitals. METHODS We searched the electronic databases Pubmed, the Cochrane Database of Systematic Reviews, EMBASE, CINAHL, PsycINFO, PEDRO and TRIP from January 2009 to March 2015, for systematic reviews that included at least one comparative study, evaluating any non-pharmacological intervention, to prevent falls amongst older adults. The quality of the reviews was assessed using AMSTAR and ProFaNE taxonomy was used to organize the interventions. RESULTS Fifty-nine systematic reviews were identified which consisted of single, multiple and multifactorial non-pharmacological interventions to prevent falls in older people. The most frequent ProFaNE defined interventions were exercises either alone or combined with other interventions, followed by environment/assistive technology interventions comprising environmental modifications, assistive and protective aids, staff education and vision assessment/correction. Knowledge was the third principle class of interventions as patient education. Exercise and multifactorial interventions were the most effective treatments to reduce falls in older adults, although not all types of exercise were equally effective in all subjects and in all settings. Effective exercise programs combined balance and strength training. Reviews with a higher AMSTAR score were more likely to contain more primary studies, to be updated and to perform meta-analysis. CONCLUSIONS The aim of this overview of reviews of non-pharmacological interventions to prevent falls in older people in different settings, is to support clinicians and other healthcare workers with clinical decision-making by providing a comprehensive perspective of findings.

Abstract
Although old people make up an extremely vulnerable road-user group, older pedestrians' difficulties have been studied less extensively than those of older drivers, and more knowledge of this issue is still required. The present paper reviews current knowledge of older-adult problems with the main components of pedestrian activity, i.e., walking and obstacle negotiation, wayfinding, and road crossing. Compared to younger ones, old pedestrians exhibit declining walking skills, with a walking speed decrease, less stable balance, less efficient wayfinding strategies, and a greater number of unsafe road crossing behaviors. These difficulties are linked to age-related changes in sensorial, cognitive, physical, and self-perception abilities. It is now known that visual impairment, physical frailty, and attention deficits have a major negative impact on older pedestrians' safety and mobility, whereas the roles of self-evaluation and self-regulation are still poorly understood. All these elements must be taken into consideration, not only in developing effective safety interventions targeting older pedestrians, but also in designing roads and cars. Recent initiatives are presented here and some recommendations are proposed.

Abstract
Purpose: To customize clinical practice guidelines (CPGs) for cataract management in the Iranian population. Methods: First, four CPGs (American Academy of Ophthalmology 2006 and 2011, Royal College of Ophthalmologists 2010, and Canadian Ophthalmological Society 2008) were selected from a number of available CPGs in the literature for cataract management. All recommendations of these guidelines, together with their references, were studied. Each recommendation was summarized in 4 tables. The first table showed the recommendation itself in clinical question components format along with its level of evidence. The second table contained structured abstracts of supporting articles related to the clinical question with their levels of evidence. The third table included the customized recommendation of the internal group respecting its clinical advantage, cost, and complications. In the fourth table, the internal group their recommendations from 1 to 9 based on the customizing capability of the recommendation (applicability, acceptability, external validity). Finally, customized recommendations were sent one month prior to a consensus session to faculty members of all universities across the country asking for their comments on recommendations. Results: The agreed recommendations were accepted as conclusive while those with no agreement were discussed at the consensus session. Finally, all customized recommendations were codified as 80 recommendations along with their sources and levels of evidence for the Iranian population. Conclusion: Customization of CPGs for management of adult cataract for the Iranian population seems to be useful for standardization of referral, diagnosis and treatment of patients.

Abstract
The aim of the present study was to measure gait velocity in cataract and simulated patients. The study was performed on 239 cataract patients, 115 age-matched subjects, and 11 simulated patients. We measured gait velocity and analyzed gait using a three-dimensional motion analysis system. Mean gait velocity before and 2 and 7 months after cataract surgery was 0.91 ± 0.19, 1.04 ± 0.21, and 1.06 ± 0.21 m/s, respectively, for males and 0.84 ± 0.22, 0.91 ± 0.24, and 0.92 ± 0.25 m/s, respectively, for females. The increase after surgery was significant in both groups at 7 months (P < 0.05). Gait velocity was significantly slower in cataract patients compared with controls before surgery, but no longer different after surgery. In simulated patients, mean velocity was 87.0 ± 11.4% of normal vision with a 3° visual field and 92.4 ± 12.3% of normal when counting fingers. Initial velocity was 89.1 ± 14.6% of normal vision with a 3° visual field and 92.7 ± 11.6% of normal when counting fingers. There was a significant difference between normal and impaired visual function (P < 0.05). The results demonstrate the close relationship between visual function and gait in cataract patients and simulated patients.

Abstract
BACKGROUND Previously, we reported improvements in sleep quality and gait speed after implantation of a yellow-colored, blue light-blocking intra-ocular lens (IOL). This study evaluated systemic health parameters for 7 months after cataract surgery with implantation of a clear, ultraviolet (UV)-blocking IOL. METHODS A total of consecutive 71 patients (average age 74.1 years) underwent cataract surgery with the implantation of a clear, UV-blocking IOL. Participants were evaluated using the Pittsburgh Sleep Quality Index (PSQI) and the National Eye Institute Visual Function Questionnaire (VFQ-25) before and at 2 and 7 months after surgery. Four-meter gait speed was also determined. The metabolic parameters of serum glycated hemoglobin (HbA1c), triglycerides (TGs), low-density lipoprotein cholesterol (LDL-C), and high-density lipoprotein cholesterol (HDL-C) were tested. RESULTS The pre-operative and post-operative (2 and 7 months after surgery) results were 66.4±16.5, 79.5±12.6, and 81.0±13.0 for VFQ-25 score, 5.7±3.5, 5.1±3.1, and 4.8±2.9 for PSQI, and 0.90±0.22, 0.91±0.22, and 0.92±0.22 meters/sec for gait speed. Significant improvements following surgery were noted in the VFQ-25 score for all cases and in the PSQI for poor sleepers (preoperative PSQI >5.5) (P<0.05, paired t-test). The gait speed and metabolic parameters showed no significant changes. CONCLUSIONS Cataract surgery with implantation of an UV-blocking clear IOL has the potential for improving circadian rhythm and systemic health parameters.

Abstract
PURPOSE Cataract surgery has potential systemic health effects. Gait speed is a potential health index of predicted life expectancy and incidence of severe illness. We thus measured quality of vision and gait speed before and after cataract surgery. DESIGN A prospective clinical study. METHODS We followed up 30 patients for 6 months following cataract surgery by implantation of a yellow soft acrylic lens. A 4-m gait speed was determined, and patients were evaluated before and after surgery using the National Eye Institute Visual Function Questionnaire (vision-related quality of life) as well as ophthalmological and systemic examinations. Life span was estimated on the basis of standard curves derived from a literature. RESULTS Mean preoperative gait speed was 0.81 ± 0.23 m/s, with significant increases recorded at 2 and 6 months after surgery to 0.85 ± 0.20 and 0.91 ± 0.22 m/s, respectively (P < 0.01, paired t test). According to patient survival determined by gait speed, life expectancy (years) before and 6 months after surgery was approximately 83.4 and 84.9, respectively, for men (1.5-year increase) and 88.8 and 89.8, respectively, for women (1.0-year increase). The mean preoperative 25-item Visual Function Questionnaire score was 59.2 ± 16.3, and significant improvements were observed 2 months (76.2 ± 13.9) and 6 months (78.6 ± 14.4) after surgery (P < 0.001, vs preoperative score). CONCLUSION In conclusion, cataract surgery improved quality of vision and gait speed for 6 months.

Abstract
INTRODUCTION Many elderly in care institutions in The Netherlands are visually impaired (visual acuity < 0.3). They fall more frequently, are more depressed and require more care. In this project visually impaired residents were identified and referred for adequate eye care. The aim of this study is to evaluate the intervention, including validation of the screening, assessment of the prevalence and causes of visual impairment as well as the outcome of the treatment. The effectiveness of the care chain is also evaluated. MATERIALS AND METHODS 640 residents were offered a basic eye examination and 210 of them were referred, via their general practitioner, to an optometrist (10), ophthalmologist (98), or centre for visually impaired persons (1). RESULTS Compliance in this study was poor. The prevalence of visual impairment (24%) was lower than in comparable studies. Cataract was the main cause in 51%. Overall 17 (8.1%) residents were treated by ophthalmologists and nine (4.3%) were referred to optical shops. Constraints in the care chain are identified. DISCUSSION Vision screening in care institutions for elderly is feasible and useful. The care chain should be shorter and simpler. That will increase the effectiveness of this intervention, and thereby the quality of life for many residents.

Abstract
UNLABELLED The aim of this systematic review was to synthesize and appraise the evidence of benefits of second-eye cataract extraction for visual function, patient-reported quality of life, falls, and driving ability among the elderly. We conducted a comprehensive search in MEDLINE using "surgery," "cataract extraction," "second eye," and "bilateral." Ten studies met the inclusion and quality criteria. We found "moderate" evidence supporting improvement in stereopsis, stereoacuity, and anisometropia over and above the benefits of first-eye surgery. We also found "moderate" evidence supporting improvement in visual acuity, contrast sensitivity, and self-reported visual functioning. Studies included in the review do not provide definitive evidence of second-eye surgery benefits on health-related quality of life, visual fields, falls prevention, and driving performance. However, the heterogeneity of outcome measures and the limited number of studies likely contributed to our findings. The findings have implications for clinicians and policymakers in the health-care industry and emphasize the need for additional trials examining this important and widely performed clinical procedure.

Abstract
Our purpose was to identify risk factors for falls among older adults who had recently undergone hip fracture surgery. The subjects in this study were 69 older adults (aged 65 years or more) who had sustained a hip fracture and were admitted to an orthopedic rehabilitation ward after surgery. Potential fall risk factors were assessed using the physiological profile assessment, timed-up-and-go test, berg balance test, and activities-specific balance confidence scale at discharge from the hospital. Each individual was followed for a period of 6 months to obtain information on the incidence of falls. Receiver operating characteristic curves were constructed to determine the optimal cutoff score for each potential risk factor identified. Multivariate logistic regression was then used to identify the significant predictors of falls and their odds ratios (ORs). During the 6-month follow-up period, 10 of the 69 patients experienced one or more falls. The results showed that fallers were older than nonfallers (p=0.009). Fallers also had poorer performance in the high-contrast visual acuity test (p=0.015) and lower knee flexor (p=0.021) and knee extensor (p=0.005) muscle strength values. Multivariate logistic regression analysis showed that high-contrast visual acuity (cutoff score Z=-2.280, OR=6.14, 95% CI 1.13-33.29, p=0.035) and knee extensor muscle strength (cutoff score Z=-1.835, OR=4.81, 95% CI 1.04-22.33, p=0.045) were predictors of falls. Poor visual acuity and knee muscle weakness are modifiable predictors of falls and should be the key target areas in fall-prevention programs for older adults with hip fractures.
