ObjectiveTo report the results of a global survey on cataract practice patterns related to preoperative, intraoperative and postoperative care, surgical setting and personnel allocation.Methods and analysisAn online 28 questions survey was sent to 240 ophthalmologists asking to describe prevailing trends in their institutions across 38 countries and 5 continents. Questions inquired country, institution, surgical volume and setting, anaesthesia, preoperative and intraoperative examination and postsurgical care. Statistical analysis used crosstabs lambda statistics for non-parametric nominal variables. P value less than 0.05 was considered statistically significant.Results209/240 (87%) ophthalmologists responded: 38% representing public hospitals, 36% private practices and 26% academic sites; overall surgical volume was between 241 700 and 410 500 cataracts per year. There was a significant correlation between type of institution and surgical volume. Complete results available in online (https://freeonlinesurveys.com/r/W6BcLLxy).ConclusionCataract surgery related patterns of perioperative care showed significant difference among respondents, regardless to type of institution, surgical volume and country. Many evidence-based procedures are unevenly practiced around the world and some widespread and expensive habits lack solid scientific evidence while consuming enormous amount of resources both monetary and human. There is a need to reach consensus and share evidence-based practice patterns.

Background: Pediatric cataracts are major causes of children’s blindness. Surgery has proven to be beneficial in terms of visual function prognosis. Contrast sensitivity evaluation after surgery is as important as visual acuity considering that natural world consists of various objects in low-to-medium contrasts. The purpose of this study is to analyze the difference of contrast sensitivity outcomes based on ages at surgery. Method: Retrospective data of children with pediatric developmental cataract from July 2013 to November 2015 were collected. All children who underwent cataract surgery at 60-months-old or less were randomized into two groups, ≤24 months and >24-to-60 months. Contrast sensitivity was then examined with preferential-looking method using Hiding Heidi low-contrast test face chart. The main outcome measures were contrast sensitivity of both groups. Age-at-evaluation, cataract onset, duration of follow-up, duration of deprivation and visual acuity were also noted. Result: Of 14 children (23 eyes), 11 eyes (47,8%) were in ≤24 months group, 12eyes (52,2%) were in >24-to-60 months group. All eyes underwent cataract extraction and similar type of intraocular lens implantation. Mean age-at-surgery was 28,2 months±16,8 (SD). Mean contrast sensitivity for each group was 47,50 %±42,29 and 18,33%±27,38, respectively, with p-value 0,031. Further analysis of Spearman’s correlation test demonstrated significant negative correlation (rs = -0,559; p = 0,006) between the two groups. Conclusion: There was statistically significant difference in contrast sensitivity between those who underwent surgery at ≤24 months and >24-to-60 months. Children who underwent surgery at older ages tend to have better contrast sensitivity afterwards.

Objective: Aim of the study is to Compare the astigmatism induced by a reduced temporal sclerocorneal tunnel incision manual small incision cataract surgery with an extended temporal clear corneal Phacoemulsification of similar width . Methods: A Prospective, randomised controlled study was carried out in 224 selected patients who were again divided into two groups - Group A (112 patients) and Group B (112 patients). Group A patients underwent temporal manual small incision cataract surgery with a 5.5 mm sclerocorneal incision and Group B underwent phacoemulsification by a 2.8 mm clear corneal temporal incision which was extended to 5.5 mm before IOL implantation. In both groups, a 5.25 mm rigid PMMA IOL was implanted in the bag. UCVA and BCVA of both group of patients was quantified and analyzed at 1 week and at 6 weeks Observation: It was seen that the mean surgically Induced astigmatism in group A (N=112) was 0.5625D , which was slightly lesser than that in Group B (N=112) which was 0.65D, although the p-value of 0.26 indicated that there was statistically no significant difference in visual outcomes between the two groups of patients. Here, a p-value of < 0.05 was considered statistically significant. Conclusion: In Skilled and Safe hands, refractive outcomes following performing a 5.5mm temporal sclerocorneal frown-incision manual small incision cataract surgery and a phacoemulsification procedure by a 2.8mm temporal clear corneal incision extended to 5.5mm for implanting a 5.25mm rigid PMMA IOL , are comparable.

Objective: To determine the mean change in central macular thickness after cataract surgery and to compare the mean change in central macular thickness after cataract surgery in non-diabetics and diabetics without diabetic retinopathy Study design: Case control   Study settings and duration: A case control study was carried out at Ophthalmology department, POF hospital, Wah Cantt. Study duration was 6 months (April 2019-September 2019)   Material and methods: A sample size of 60 patients was calculated by using Open Epi Software. We used non probability consecutive sampling. Patients were divided into two groups; Cases (Diabetic) and controls (non-Diabetic). All patients underwent phacoemulsification and observed after 4 weeks for macular thickness measurement using optical coherence tomography before and after surgery. Data analysis was done with SPSS version 20. Post stratification t test was applied. P value ≤0.05 was considered significant.   Results: Total 60 patients were included. Mean age of patients was 65.31 ±7. 63SD.There were 35 (58.3%) males and 25 (41.7%) female patients in the study. We found a significant increase in central macular thickness in cases and controls [(223.100±15.86SD vs 227.2667±17.9SD, p=0.000) and (221.200±12.16SD vs 226.289±16.7861SD, p =0.001)] before and after phacoemulsification in cases and controls respectively. However, no significant difference was found between the groups (p=0.486).   Conclusion: Central macular thickness was increased after uncomplicated phacoemulsification in both diabetics and non-diabetics without retinopathy for up to a follow-up period of 4 weeks but the thickness did not differ between the two groups.

Background: Several studies have shown comparable visual outcomes of SICS and phacoemulsification (Gogate et al 2007, Ruit et al 2007). Objective: To compare the safety and efficacy of different types of surgical procedures (phacoemulsification versus SICS) for cataract surgery in immature cataract. Material and methods: A prospective randomized controlled trial was carried out involving 93 and 89 patients with immature senile cataract selected for phacoemulsification and SICS respectively. Statistics: Mean values with standard deviations were calculated. P value of less than 0.05 was considered significant. Results: There was no difference between the groups in terms of gender, age and pre-operative visual acuity (p = 0.09). In phacoemulsification group (n=93) more than two thirds and in SICS group (n=89) more than three quarters of the patients had good visual outcome (6/6-6/18) on first postoperative day (p=0.065). Poor outcome (<6/60) was recorded in 6% (phacoemulsification group) and 1% (small incision cataract surgery group). Mean visual acuity was 0.43 ± 0.27 in phacoemulsification group and 0.47 ± 0.24 in SICS group. Mean surgery time was significantly shorter in SICS group (p=0.0003). Statistics: Data were computed and analyzed using the SPSS software program vs 10. The p value of < 0.05 was considered significant. Conclusion: There was no significant difference in visual outcome on first post operative day in between phacoemulsification and SICS technique. However, performing SICS was significantly faster. Small incision cataract surgery with implantation of rigid PMMA lens is a suitable surgical technique to treat immature cataract in developing countries.

Abstract BackgroundPatients with systolic heart failure are at high risk of admission to hospital and death. This can be reduced by ensuring that they are receiving all evidence-based heart failure medications and by detecting early signs of deterioration in their condition.MethodsWe recruited 209 primary care patients with echocardiographically proven left ventricular systolic dysfunction (ejection fraction < 40%). 84 patients consented to be actively monitored by the heart failure team using telemedicine. 125 patients consented to receiving usual care but allowing access to their medical records. The primary end-point was cardiovascular death or admission to hospital for heart failure at 1 year. Secondary end-points included the prescription of evidence-based heart failure medications and patient satisfaction at the end of the study.ResultsThere was no difference in the mortality rate between the groups (6.02% in the active group and 5.56% in control). There was a significant difference in hospital admission (10.84% in the active group and 1.59% in control; p-value of 0.0078). At the end of the study, in the active group v control group, 92% v 52% of patients were on a beta-blocker, 92% v 48% on ACE-I/ARB, and 60% v 30% on an MRA. There were no differences in the final doses achieved.ConclusionsActive telemonitoring in an elderly population with systolic heart failure did not reduce cardiovascular mortality or admission to hospital for heart failure over the 1 year of the study. It did result in more patients receiving evidence based heart failure medications.Trial registrationThis trial received ethical approval from the Health Research Authority London-City Road and Hampstead Research Ethics Committee (REC Reference: 16/L0/0070, IRAS project ID: 173818). The ClinicalTrials.gov Identifier number is: NCT04371731. This trial was retrospectively registered on 30/4/2020 and this study adheres to CONSORT guidelines

Purpose: The purpose of this study was to evaluate the myopic shift over a period of 2 years following implantation of intraocular lens (IOL) in children less than 2 years of age with axial length less than 22 mm.Method: A retrospective analysis of records of children below 2 years of age with axial length less than 22 mm who had undergone cataract surgery with primary IOL implantation over a period of 7 years was undertaken. Mean myopic shift was analyzed at 6 months, in first year, second year and end of 2 years following surgery.Results: Total 40 eyes of 23 children were included (mean age 13.55±7.38 months); with mean myopic shift at end of 2 years -2.35±2.15. Myopic shift in eyes with undercorrection in range of 3-4 D (group-I) and 5-7 D (group-II) was compared using Mann-Whitney test. Mean myopic shift at end of 2 years was -2.93±2.55 in group-I and -1.88±1.77 in group-II (p value not significant). There was no significant difference in myopic shift between two groups at 6 months and 1 year; a borderline significant difference was found in second year (p= 0.04).Conclusion: In our study amount of myopic shift in first two years in children with axial length less than 22 mm is below the expected normal. There was not much significant difference in the myopic shift over a period of 2 years in eyes, which were undercorrected by 3-4 D against those with 5-7 D. Thus aiming for less residual hyperopia by less undercorrection did not increase myopic shift. Thus high-level hyperopic glasses in the early years could be avoided and help in prevention of amblyopia after paediatric cataract surgery.

Summary Team-based learning (TBL) is a well-established instructional strategy that provides students with the chance to apply conceptual knowledge through a series of actions, including pre-class, individual, team class activity, and immediate feedback. The purpose of the present study was to introduce a course of teaching the evidence-based medicine (EBM) to all first-year medical residents in different disciplines at Shiraz Medical School in Iran country using the TBL instructional strategy. The sample included 86 medical residents at Shiraz Medical School. This study had a quasi-experimental design and was conducted in 12 sessions of evidence-based medicine (EBM) based on team-based learning (TBL) strategy. The obtained data were analyzed using SPSS software. In all sections, the results of Individual Readiness Assurance Tests (IRATs) and Group Readiness Assurance Tests (GRATs) were added and calculated. Cronbach’s alpha test was implemented to evaluate the reliability of the questionnaires. For the descriptive analysis of data, descriptive statistics were used. ANOVA and T-test were used for analytic analysis. There was a significant difference in answering the questions between individual (3.73 ± 2.33) and group (4.71 ± 2.29) stages. Residents gained higher average grades on working in the team (P-value < 0.02). Results of residents’ response about satisfaction questionnaire are shown that the best scores belong to group activities in TBL. The results of this study showed that TBL could be used as an effective method for residents’ education in different disciplines.

Background: Hypertension is one of the most common conditions seen in primary care and the consequences are fatal if not diagnosed early and managed appropriately. Patients want to be sure that hypertension management will decrease their disease burden, and clinicians need guidance on hypertension treatment using the best scientific evidence. Objective: The primary objective is to evaluate the awareness of the Eighth Joint National Committee Guidelines among internists in the Al-Ahsaa area. Method: This was a cross-sectional observational study that evaluated 43 internists randomly chosen in Al-Ahsaa area by using a questionnaire containing 16 questions that reflect on their awareness of the Eighth Joint National Committee Guidelines. Passing 80% of the 16 questions is described as fair awareness of the Eighth Joint National Committee Guidelines. Results: The average of right answers percentages among the 43 evaluated internists was 54.07% ± 25.6%. The averages of right answers percentages among 16 physicians, 14 specialists and 13 consultants were 75.78% ± 20%, 47.76% ± 16% and 34.13% ± 20%, respectively, which showed a significant difference (P-value < 0.00001) between them. Conclusion: The awareness of the Eighth Joint National Committee Guidelines among internists in Al-Ahsaa area is not good enough. However, physicians showed significantly better awareness of the Eighth Joint National Committee Guidelines than specialists and consultants. Increasing the awareness of internists about new guidelines for hypertension is highly recommended, through workshops that could be provided by the Ministry of Health.

Abstract Background To examine the characteristics of rhegmatous retinal detachment (RRD) associated with atopic dermatitis. Method Medical records of 2257 patients who underwent RD surgery at this clinic between 2008 and 2018 were retrospectively reviewed. Among them, 61 patients who were diagnosed as AD were assigned into the experimental group and 100 patients who did not have AD were randomly selected and assigned into the control group. Demographics, characteristics of detachment, initial operative method, and prognosis after surgery were investigated as main outcomes. Additionally, in pseudophakic RD patients, the period between the cataract surgery and onset of RD was measured. Result Postoperative VA and prognosis were significantly worse and bilateral involvement of RD was more common in the atopy group than in the control group. (P value = 0.005, 0.001 each) Characteristics of retinal breaks were different between the two groups. Additionally, the risk of developing RD within 1 year after cataract surgery was significantly higher in pseudophakic patients of the atopic group than in the control group. (P value = 0.013) However, there was no significant difference in mean preoperative VA or refractive index between the two groups. Conclusion Our results show that in atopic patients, RD occurs at a young age with different characteristics compared to non-atopic patients. Atopic RD has a poor visual prognosis. Thus, it requires careful management. Furthermore, the risk of developing RD within 1 year after cataract surgery is higher in atopic patients. Therefore, it is important to perform regular and extensive check-up after cataract surgery for atopic patients.
