Acta Biomater 2024; 178:124-136. [PMID: 38423352 DOI: 10.1016/j.actbio.2024.02.033] [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: 01/05/2024] [Revised: 02/17/2024] [Accepted: 02/20/2024] [Indexed: 03/02/2024]
Abstract
Intraocular lens (IOL) implantation is currently the most effective clinical treatment for cataracts. Nevertheless, due to the growth of the eye axis in patients with congenital cataracts during the process of growth and development, the progressive incapacity of an IOL with a fixed focus does not meet the demands of practical usage, leading to the occurrence of ametropia. This work describes an innovative class of an IOL bulk material that offers good biosafety and light-controlled refractive index adjustment. Acrylate materials were synthesized for the preparation of IOLs by free radical polymerization of ethylene glycol phenyl ether methacrylate (EGPEMA), hydrophilic monomer 2-(2-ethoxyethoxy) ethyl acrylate (EA), and functional monomer hydroxymethyl coumarin methacrylate (CMA). Under 365/254 nm ultraviolet (UV) irradiation, the coumarin group could adjust the polymer material's refractive index through reversible photoinduced dimerization/depolymerization. Meanwhile, the potential for the IOL use is enabled by its satisfactory biosafety. Such a light-induced diopter adjustable IOL will be more appropriate for implantation during cataract surgery since it will not require the correction needed for ametropia and will offer more accurate and humane treatment. STATEMENT OF SIGNIFICANCE.

Abstract
Background Five-fifths of all incidents of blindness in Saudi Arabia may be attributed to cataracts. Cataracts are the second major cause of blindness, responsible for 35.5% of cases. Therefore, the purpose of the research was to measure the visual acuity improvement after cataract surgery in children. Materials and Methods This systematic review followed PRISMA guidelines for reporting systematic reviews. All procedures followed the recommendations of the Cochrane handbook. Studies of varying study designs, both published and unpublished, are included. Retrospective studies with outcomes of pediatric cataract surgery were identified from various databases. Result After an initial screening, 108 out of 167 items were deemed unsuitable for publication. There were 59 full-text papers assessed for inclusion, and only seven matched the criteria. All the articles included were of a very high standard. Both the duration of therapy and the target population varied widely between the studies. Conclusion The results indicated that the majority of childhood cataracts are hereditary. Primary posterior capsulectomy and anterior vitrectomy combined with cataract extraction and intra-ocular lens implantation is the treatment of choice for pediatric cataracts. It is recommended that surgery be performed in a properly equipped facility staffed by trained, cooperative personnel and that different procedures be used to enhance post-operative follow-up.

Abstract
Importance As critical determinants of scientific rigor, reproducibility, and equity, sex and gender should be considered in clinical trial design and reporting. Objective To evaluate the accuracy of sex and gender reporting and extent of sex- and gender-based analysis in clinical trials associated with US Food and Drug Administration (FDA) drug approvals between January 1, 1995, and December 31, 2022. Design, Setting, and Participants In this cross-sectional study of participants enrolled in FDA ophthalmology trials, the following trial documents were reviewed by pairs of independent reviewers in decreasing order of priority: peer-reviewed publication, ClinicalTrials.gov report, and FDA medical and statistical reviews. Trial protocols and supplementary materials were also reviewed. Main Outcome and Measures The proportion of trials that correctly applied sex and gender terminology, reported the method of assessing sex or gender, and conducted sex- or gender-based data analysis; incorrect application of sex and gender terminology was defined as interchangeable use of sex- and gender-related terms without a clear justification. Results Between 1995 and 2022, 34 ophthalmic drugs corresponding to 85 trials (34 740 participants) received FDA approval, of which 16 drugs (47.1%) corresponding to 32 trials (18 535 participants [37.6%]) were associated with peer-reviewed publications. Sixteen trials used sex and gender terminology correctly (19.5%). No trial reported how sex and gender were collected nor enrolled participants from sexual and gender identity minority populations. Most trials reported sex- and gender-disaggregated demographic data (96.5%), but few conducted sex- or gender-based analysis for data on dropout (1.2%), primary outcomes (28.2%), secondary outcomes (2.4%), and adverse events (9.4%). Erroneous sex and gender reporting was associated with later publication year (2008.5 vs 2001.0; median difference, 7.5; 95% CI, -6.0 to 11.0; P < .001) and higher journal influence metrics, including 2022 journal impact factor (13.7 vs 5.9; median difference, 7.8; 95% CI, -1.4 to 152.4, P < .001) and 2022 journal citation indicator (4.9 vs 2.1; median difference, 2.9; 95% CI, 0-20.0, P < .001). Conclusions and Relevance In this observational study, over three-quarters of ophthalmology trials associated with FDA drug approvals conflated sex and gender and over two-thirds lacked sex- and gender-based analyses. More rigorous integration of sex and gender appears warranted for FDA, and presumably other trials, to improve their validity, reproducibility, and equity.

Abstract
Background To predict postoperative visual acuity (VA) in patients with age-related cataracts using macular optical coherence tomography-based deep learning method. Methods A total of 2,051 eyes from 2,051 patients with age-related cataracts were included. Preoperative optical coherence tomography (OCT) images and best-corrected visual acuity (BCVA) were collected. Five novel models (I, II, III, IV, and V) were proposed to predict postoperative BCVA. The dataset was randomly divided into a training (n = 1,231), validation (n = 410), and test set (n = 410). The performance of the models in predicting exact postoperative BCVA was evaluated using mean absolute error (MAE) and root mean square error (RMSE). The performance of the models in predicting whether postoperative BCVA was improved by at least two lines in the visual chart (0.2LogMAR) was evaluated using precision, sensitivity, accuracy, F1 and area under curve (AUC). Results Model V containing preoperative OCT images with horizontal and vertical B-scans, macular morphological feature indices, and preoperative BCVA had a better performance in predicting postoperative VA, with the lowest MAE (0.1250 and 0.1194LogMAR) and RMSE (0.2284 and 0.2362LogMAR), and the highest precision (90.7% and 91.7%), sensitivity (93.4% and 93.8%), accuracy (88% and 89%), F1 (92% and 92.7%) and AUCs (0.856 and 0.854) in the validation and test datasets, respectively. Conclusion The model had a good performance in predicting postoperative VA, when the input information contained preoperative OCT scans, macular morphological feature indices, and preoperative BCVA. The preoperative BCVA and macular OCT indices were of great significance in predicting postoperative VA in patients with age-related cataracts.

Abstract
Importance Deficient ophthalmologic care is costly to patients, making the identification of groups not receiving adequate care of vital importance. The current landscape of equity in ophthalmic care has yet to be thoroughly investigated and is important to ensure inclusivity and patient-centered care. Objective To perform a scoping review of the literature pertaining to health care inequities in the field of ophthalmology. Evidence Review A comprehensive database search using MEDLINE (via PubMed) and Ovid Embase was done in July 2022. English-language articles published from 2016 to 2021 were included and encompassed all article types except commentaries or correspondence. The search modeled the National Institutes of Health list of designated US health inequity populations, which includes income, education level, occupational status, rural and underresourced area, sex and gender, lesbian, gay, bisexual, transgender, and queer (LGBTQ) identity, and race and ethnicity. A total of 8170 abstracts and titles were screened by 2 independent investigators, and 189 studies were assessed in full text for eligibility. For inclusion, articles needed to be an ophthalmic study discussing health inequities. In a masked, duplicate fashion, 2 independent investigators screened 75 full-text studies for data extraction using a pilot-tested form. Data extraction included general publication characteristics and health inequity data based on the National Institutes of Health's defined inequity groups. Findings A total of 75 publications were included. Notable inequities were found among Black and Hispanic patients associated with negative ophthalmic outcomes and mixed associations regarding sex or gender. Overall, lower-income patients were more likely to have vision impairment, use eye care services less, and have lower adherence to eye examinations. No articles within our sample examined LGBTQ inequities among ophthalmology patients since the 2016 National Institutes of Health classification of sexual and gender minority populations. Substantial research gaps were observed within the ophthalmic literature pertaining to the LGBTQ community, race and ethnicity, and rural and underresourced areas. Conclusions and Relevance This scoping review found substantial findings associated with the LGBTQ community, race and ethnicity, and the role of telemedicine in rural and underresourced areas. Because of the importance of ophthalmic care in overall patient health, it is vital to understand the various inequities present and strive to improve the current gaps in the literature. Future studies should (1) examine barriers to clinical study and medical trainee recruitment as well as patient values and preference studies and (2) investigate the implementation of telemedicine in underresourced areas.

Abstract
Introduction Pediatric cataract is still a major cause for childhood visual impairment. The goal of our study was to analyze the prevalence of children with impaired vision (6/15 or worse) after surgery for bilateral cataract, to evaluate factors associated with it and to emphasize the importance for visual rehabilitation including the use of visual aids, educational measures, and social worker services. Methods Retrospective analysis of medical records from children who underwent surgery for cataract up to age 6 years, with a follow-up of at least 4 years. Clinical characteristics retrieved from medical records included visual acuity, presence of nystagmus and/or strabismus, age at surgery, intraocular lens (IOL) implantation, and others. Results Fifty-five children were included in the study. Follow-up ranged from 4 to 13 years (Mdn = 6.8). Visual impairment was found in 15/24 (62.5%) of children operated on before the age of 6 months (group 1), and in 7/31 (22.5%) n those operated after the age of 6 months (group 2; p = .019). Thirty-eight of the 55 children had a primary IOL implantation; nystagmus and microphthalmos were also associated with higher rates of visual impairment. Discussion Despite early and modern surgery, long-term visual outcome remains poor in children undergoing bilateral cataract surgery at young age. When discussing visual prognosis with parents, it is important to recognize factors associated with visual impairment, such as need for surgery before age 6 months, nystagmus and microphthalmos, as well as the importance for early visual rehabilitation services when needed. Implications for Practitioners Our study aims to highlight the high number of children left with visual impairment and blindness following modern and timely treatment for early cataract. Early referral for visual rehabilitation will optimize quality of life in these children and will probably allow a wider range of opportunities as adults.

Abstract
We followed visual development in a rare yet large sample of patients with congenital bilateral cataract for 4 years. We divided the patients into two groups: a complete deprivation group with no response to a flashlight pointing to either of their eyes and otherwise an incomplete deprivation group. All the patients received cataract surgery at age of 3 months. From 27 months onward, the complete deprivation group showed better developmental outcomes in acuity and eyeball growth than the incomplete deprivation group. Such a seemingly counterintuitive finding is consistent with research on visually deprived animals. Plasticity is better preserved in animals receiving a short period of complete visual deprivation from birth than in animals who saw diffuse light. The current finding that plasticity in visual development is better preserved in human infants with complete visual deprivation than in those who can see diffuse light but not patterned visual input has important clinical implications. Infants with complete deprivation have developed better acuity than incomplete ones Plasticity is better preserved in complete deprivation infants than in incomplete ones Infants with complete deprivation have less myopic shift than incompletes ones Early noisy input has the detrimental effect on human visual development

Abstract
Advances in technology have made surgery in children safer and faster. The management of pediatric cataract has made rapid progress in the past decade with the availability of safer anesthesia, newer technique's, more predictable intraocular lens (IOL) power calculation, a better understanding of neurobiology, genetics, amblyopia management, improved IOL designs for preventing visual axis opacification, and adjuvant postoperative care. Modern vitrectomy machines with minimally invasive instruments, radiofrequency, diathermy, and plasma blades help immensely in complicated cases. Preoperative evaluation with ultrasound biomicroscopy and optical coherence tomography (OCT) allows better planning of surgical procedure. The future holds good for stem cell research, customized OCT, and Zepto (precision pulse capsulotomy).
