Indications and outcomes of intraocular Lens Exchange among pseudophakic eyes in a Tertiary Referral Center.

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

How to create a successful mobile learning strategy for medical education during lockdowns?

BACKGROUND: Mobile learning has played an important role during the COVID-19 pandemic and medical schools now consider it as an effective educational method in current and future crises. In this qualitative study, an attempt was made to demonstrate the principles of designing a mobile learning strategy in medical education from the perspective of experts. MATERIALS AND METHODS: The study was conducted by the qualitative content analysis method. The data were collected from July 2022 to Feb 2023. Twelve participants were included in this study from Iran's medical universities, consisting of two members of the Higher Council of Virtual Education, three educational directors, three clinical faculty members, two faculty members specializing in e-learning and medical education, an educational vice, and a dean. Data were collected using semi-structured interviews and analyzed by Granheim and Lundman's (2004) method. RESULTS: Out of twelve participants in the study, eight (66%) were males and four (44%) females. Data were classified into eight categories and one theme. Based on the participants' experiences, the main theme, that is, "the principles of medical education design in mobile learning," included pedagogical component, interactive design, effective and comprehensive analysis, achieving objectives with the mobile learning platform, generating micro- and interactive e-content, teaching-learning interactive methods, course implementation and interactive evaluation at both micro- and macro-levels. CONCLUSION: Data analysis revealed that in addition to the eight principles in the medical education design in mobile learning, the participants prioritized the two principles of pedagogical component and interactive design over other principles in educational design. Using a successful mobile learning strategy in situations of restrictions limiting physical presence may improve the quality of medical education.

A Qualitative Study on Continuing Medical Education Programs for Practicing Ophthalmologists in Iran: Changing Previous Norms.

INTRODUCTION: The Continuing Medical Education (CME) programs in the medical community aim to improve the knowledge of practitioners and its effect on changing their performance. Previous studies showed that CME causes minimum changes in physicians' behaviors, so it is important to pay attention to the views of this group. In this regard, this qualitative study aimed to explain the Iranian Ophthalmologists' perceptions and experiences concerning the CME Programs in Iran. METHODS: In this qualitative study, 18 participants, including 10 subspecialists and 8 general ophthalmologists, were recruited to participate in in-depth interviews concerning their experiences with CME. The required data were collected from April 2018 to Feb 2019. Each interview was conducted in medical universities; eye research centers; and the ophthalmology departments, offices, and operating rooms of public and private hospitals. The current study was performed using a content analysis based on the Granheim and Lundman's methods. The codes, sub- categories, categories, and themes were then explored through an inductive process in which the researchers moved from specific to general. RESULT: The data obtained from interviews, and filed notes were analyzed and then classified into the following four themes: "growth and development of the ophthalmology's CME program over time", "challenges of the ophthalmology's CME program", "reasons for the participation of the ophthalmologist in the CME program", and "strategies for improvement". CONCLUSION: Based on the qualitative study's results, in spite of growth and development of the design and implementation of the Ophthalmologic CME programs, we are still facing multiple challenges. Enhancing the interactivity between the providers and participants can also improve the ophthalmology CME programs.

Job Satisfaction among Ophthalmologists in Iran.

Purpose: To estimate the level of job satisfaction among ophthalmologists in Iran and determine the associated factors that may impact their overall job satisfaction. Methods: In this cross-sectional study, 181 ophthalmologists (79.0% male) were interviewed by the Warr-Cook-Wall questionnaire with 7-point-Likert scale, which transformed responses from a 0 (most dissatisfied) to 100 (most satisfied). Questionnaires were randomly distributed among registered ophthalmologists at the 29 t h Annual Congress of the Iranian Society of Ophthalmology in November 2019. Satisfaction under each scale was considered as a score of > 60% of the total score. Results: A total of 181 ophthalmologists with a mean age of 47.8 ± 12.1 years and 16 ± 12 years of practice participated in the present study. They were mostly satisfied with their job as a whole (88.1%, mean score: 60.6 ± 20.7) and dissatisfied with their income (55.9%, mean score: 47.6 ± 20.3). High levels of job satisfaction was found among ophthalmologists with longer duration of practice (P < 0.001) while lower levels of satisfaction were identified among those who worked in academic centers (P = 0.004). Conclusion: In this study,high levels of job satisfaction were found among ophthalmologists with longer duration of practice while low levels of satisfaction were identified among ophthalmologists who worked in academic centers. The factors of salary and working hours accounted for the least levels of job satisfaction.

Introducing a mobile learning model in medical education during COVID-19; a critical review.

Introduction: Mobile learning is one of the innovative teaching techniques that help medical students gain knowledge and skills. One of the factors that expanded the use of this strategy was the COVID-19 pandemic. However, the educational pedagogy of such technology has been neglected. This article aimed to critically review available mobile learning models in medical education to suggest a comprehensive model in the field of mobile learning. Methods: We conducted this critical review based on the five steps of the Carnwell and Daly method. For a comprehensive systematic search from 2000 to April 2021, the following keywords were used: Personal Digital Assistant, m learning, Mobile learning, Ubiquitous learning, U learning, medical students, and medical education. 3176 studies in PubMed, Scopus, ERIC, Magiran, and Web of Science were identified. In total, 8 articles entered the study. Results: Eight models of mobile learning in medical education were identified. The key features of each model were extracted and integrated into the new model for the successful design and implementation of mobile learning. This model includes three main elements of mobile learning: 1-stakeholders, 2-interaction, and 3-technology, which are influenced by external factors including Mobiquette, legitimacy, and awareness. Conclusion: The results of this study are an important contribution to the knowledge collection in mobile learning in medical education. We introduced a comprehensive model of mobile learning including specific characteristics of strategies in the context of medical education.

Psychological Impact of COVID-19 on Ophthalmologists in Iran.

Purpose: To identify the psychological impact of coronavirus disease on ophthalmologists practicing in Iran between August and December 2020. Methods: In this cross-sectional online survey, a standard Patient Health Questionnaire- 9 (PHQ- 9) was completed by 228 ophthalmologists who were practicing in Iran. The PHQ- 9 questionnaire was revised by adding two additional questions specifically applicable for the assessment of the psychological impact of coronavirus disease on the Iranian ophthalmologists. An organized classification regarding the assessment of different depression severities identified as no (0-4), mild (5-9), moderate (10-14), or severe (15-21) was then considered for data analysis. Results: The mean age of our participants was 49.0 ± 15.61 years and the majority of them (67.1%) were male. Depression was discovered in 73.68% (n = 168) with different severities ranging from mild (n = 61, 26.75%), moderate (n = 63, 27.63%), and severe (n = 44, 19.3%). It was found that participants with depression were older as compared to those without depression (P = 0.038). Higher percentages of severe depression were noticed in the high-risk regions contaminated with corona virus as compared to the other low-risk regions (P = 0.003). Based on multivariable models, we determined that ophthalmologists who were somewhat concerned about their training/ profession (OR: 0.240; 95% CI: 0.086-0.672; P = 0.007) and those with no concerns about their income had lower association with depression (OR: 0.065; 95% CI: 0.005-0.91; P = 0.042). Conclusion: High prevalence of depression was observed among older aged Iranian ophthalmologists living in high-risk contaminated regions who possessed serious concerns with respect to their training/profession and income. It is recommended that the health policymakers of Iran pay more attention to the ophthalmologists who experience the aforementioned factors.

Relation between stress, time management, and academic achievement in preclinical medical education: A systematic review and meta-analysis.

Identifying the learners' problems is important. Besides, many factors are associated with academic failure, among which time management and stress are more important than any others based on evidence. By using a systematic review and meta-analysis, this study aims to synthesize the findings of studies about the correlation of time management and stress with academic failure to suggest a more in-depth insight into the effect of these two factors on academic failure. Four databases were searched from the inception of January 2018. Publication bias was evaluated visually using funnel plots and sized up by Egger's test. Ninety-four articles were found to be qualified for inclusion after full-text review and additional manual reference made. Of these, 8 were studies of educational interventions that were reviewed in this paper. Regarding the relation of stress and academic performance, the Funnel plot (results not shown) and Egger's test showed no publication bias in the studies (P = 0.719). Based on this result, the estimated pooled correlation (reverted by hyperbolic tangent transformation) between stress and academic performance was found to be -0.32 (95% confidence interval: -0.38--0.25). In conclusion, the review recognized a series of potentially mutable medium-to-large correlates of academic achievement, time management, and stress. It would be essential to have experimental data on how easily such self-regulatory capacities can be altered, and these interventions could help students enhance their potential, providing empirical tests for offered process models of academic achievement.

Distance learning strategies in medical education during COVID-19: A systematic review.

The current outbreak of coronavirus disease 2019 (COVID-19) across the world forced universities to suspend learning to limit the spread of the virus. Many medical schools have shifted to online education as an information delivery mechanism where the educator and learner are separated in space and potentially also in time. This systematic review aims to explore and understand the variety of distance learning strategies in medical students in the contexts of COVID-19. A systematic review was conducted in Web of Sciences, PubMed, Educational Resources and Information Center, and Scopus from December 2019 to July 2020. Eight sets of terminology were used, combining "Distance learning" AND "Medical education" AND "Pandemic." Studies were reviewed independently by two reviewers. Data were extracted and quality appraised using QualSyst tools, and synthesized by performing thematic analysis. A total of 473 articles were identified after removing duplicates and 314 records were screened, of which 125 were included in this study. The primary articles were 52 primarily qualitative articles. Five learning strategies consisted of technology-enhanced learning (TEL), simulation-based learning, technology-based clinical education, mobile learning, and blended learning. Tools, methods, and learning resources associated with these five learning strategies were extracted from the articles. Our review highlights that TEL and simulation-based learning were more commonly used than others in distance learning in medical education during the COVID-19 pandemic. These strategies have the potential to improve learners' level of knowledge and performance through making online learning resources such as Massive Open Online Courses, virtual clinical cases, and blended sources accessible.

A qualitative content analysis of "problem students": how can we identify and manage them?

OBJECTIVES: Problem students is one of the important issues in medical education. This study aimed to identify the problem students and the ways for managing these students from the educational experts view. Purposive sampling was used, and data collection continued until data saturation was achieved. Data analysis was performed by the content analysis method based on the Heidegger approach. We interviewed 12 educational experts who had a history of dealing with "problem students". RESULTS: After data analysis, five main themes and 28 categories, and 164 codes were extracted. The reasons for changing a student to a problem students was: student self-regulation skills, multilayer interactions, curriculum failure, identification policy and supportive solutions. The results indicated that despite revision in the curriculum, there were shortcomings in identification and management of problem students. According to participants, existence of a comprehensive system and a capable counseling center can identify the problem student sooner. On the other hand by improving self-regulation skills, active teaching methods and frequent formative evaluation and the use of supportive strategies, problem student can be encouraged to complete their education successfully. This study emphasized faculty development, reviewing the faculty member recruitment, strengthening counseling centers, improving the exams.

Eye Care Utilization in A Community-oriented Mobile Screening Programme for Improving Eye Health in Iran: A Cluster Randomized Trial.

PURPOSE: To evaluate the effect of a mobile-based screening programme on eye care utilization in Iran. METHOD: In this cluster randomized community trial, a representative sample of residents aged≥50 years from urban and rural areas in four districts in Tehran province were enrolled. The clusters were randomly assigned to one of the three parallel arms; the mHealth arm with digital data collection, vision screening test and retina evaluation using an integrated mobile application, the conventional arm with manual data collection and screening tests using Snellen chart and Fundus photography at the local primary healthcare facility, and the control arm with manual data collection without screening tests. The main outcome measure was eye care utilization which was defined as at least one visit to an optometrist or ophthalmologist. RESULTS: Of 3312 eligible individuals, 2520 (76.1%) participated. In the first 3 months after the screening programme, eye care utilization was higher among those who were referred by the mHealth method (35.6% 95%CI: 31.1-40.4%) compared to those referred by the conventional method (32.7%, 95%CI: 27.5-38.2%) and to those observed in the control arm (4.5%, 95%CI: 3.2-6.0). Eye care utilization improved (OR = 1.5, 95%CI: 1.2-1.9) among the referred people after the screening programme compared to the utilization before this programme; however, this improvement was significantly higher in the mHealth method (OR: 1.7, 95%CI: 1.2-2.4) compared to the conventional method (OR: 1.2, 95%CI: 0.8-1.8). CONCLUSION AND RELEVANCE: The mobile-based screening programme can significantly improve eye care utilization at the community level.

Designing a Screening Program for Prevention of Avoidable Blindness in Iran through a Participatory Action Approach.

PURPOSE: To design a screening program for prevention of blindness at the community level in Iran. METHODS: In this qualitative study, the components and properties of the screening program were identified using a participatory action research method with focus group meetings (FGMs) with relevant health care providers and authorities. A content analysis approach was used for data analysis. RESULTS: In total, 18 stakeholders including six ophthalmologists with different sub-specialties participated in the five FGMs. The screening program aims to discover vision-threatening eye conditions in people aged 50 years and over. Primary health care workers deliver the program including vision tests and fundus imaging with the support of an ophthalmic technician. Retina specialists perform decision-making. Referral plans are interacted through an automated digital program. The screening environment, feedback, ethics and medical legal issues are other main components of the program. CONCLUSION: This study presents the initial concepts and components of a screening program for prevention of blindness in the adult population in Iran. The program has the potential to improve eye health at the community level and may potentially be replicated as a model for similar settings elsewhere.
