Rice is a staple food in Indonesia, so the demand continues to increase along with the population growth. Rice cultivation in Indonesia is known for two planting systems, namely wetland rice which requires water and upland rice which is planted in fields without requiring special irrigation. Several regions in Indonesia have almost extinct upland rice varieties, such as the Fakhaito variety or black rice from Nias Regency, with a plant age of up to six months until harvest. Upland rice productivity is very low, affecting farmers' income, accompanied by suboptimal fertilization technology. This research aims to provide learning to students in using the SPAD-502Plus chlorophyll meter to detect the growth and health of upland rice plants from Nias. The results of the study show that treatment with liquid organic fertilizer correlates positively with leaf color, where the amount of chlorophyll is higher in the very green leaves of rice, and conversely the amount of chlorophyll decreases in plants with reduced greenness. The use of the SPAD-502Plus chlorophyll meter is a faster, non-destructive, comfortable, and non-disruptive way to measure plant growth, as the measurement is done directly.

Authors: Koto Eldawati
Published: February 2024

This article discusses the efforts to ensure the quality of education in Indonesia through the school accreditation process. School accreditation is a comprehensive assessment of the eligibility of educational programs based on the National Education Standards (SNP) as a form of public accountability. Accreditation is carried out by comparing the school's conditions with the four components (standards) established in IASP 2020. In its implementation, the continuous fulfillment and development of these four components lead to the provision of quality education. Accreditation is an effort to accelerate and encourage the growth and development of schools/madrasahs, and motivate them to achieve the desired standards. This is expected to create a conducive environment for educational growth, provide guidance for continuous self-evaluation, and serve as a stimulus to continue striving for the expected quality. Thus, accreditation indirectly ensures the quality of education, which is beneficial for students, teachers, and the community in choosing schools for their children.

Perbandingan Penginputan Transaksi Secara Manual Menggunakan Accurate pada Laporan Keuangan Input Transaksi Manual dengan Accurate di Laporan Keuangan
Authors: Meytha Sri , Delfin. M Vallen Ocshelyn
Published: February 2024

This abstract discusses the comparison between manual transaction input and using Accurate in financial reports. Manual transaction input method involves the process of manually entering data into the accounting system, such as recording purchase transactions, sales, and other expenses. Although this method can produce accurate financial reports, it requires more time and effort from the inputting party. In addition, the risk of error is also higher because data entry is done manually. On the other hand, using Accurate as a transaction input system can improve the efficiency and accuracy of financial reports. Accurate is an accounting software designed to assist entrepreneurs or accountants in managing company financial transactions. By using Accurate, transaction input can be done automatically through integration with various data sources, such as cash register systems, purchase systems, and sales systems. This reduces the need for manual data entry, so the required time and effort can be minimized. In addition, Accurate also comes with automatic validation features that can reduce the risk of human error in inputting transactions. This feature will check the entered data and provide warnings or notifications if there are errors or non-compliance with applicable accounting rules. Thus, the accuracy of financial reports can be improved. In this study, a comparison will be made between manual transaction input and using Accurate in financial reports. By comparing these two methods, it is hoped that information can be found to help entrepreneurs or accountants in choosing the most efficient and accurate transaction input method for their company.

In our world today, cardiovascular disease (CVD) stands as the foremost cause of death worldwide, claiming the lives of nearly 20 million individuals annually. As CVD continues to burden the healthcare industry, there is a critical need for early detection and prevention. The rise of Artificial Intelligence in the medical field offers a range of capable solutions. In order to address the problem, this paper presents the development of a simple, supervised deep learning model for detecting cardiovascular disease in patients. The research focused on creating a model enriched with multiple layers, activation functions, optimizers, and loss functions. The chosen approach leveraged the power of AI to analyze labeled patient data and map input features to corresponding class labels, enabling accurate detection of CVD. The dataset used contained 70,000 patient records with 12 different clinical attributes. In addition, it provides an overview of the most common types of cardiovascular disease, such as coronary artery disease, aortic valve disease, stroke and peripheral artery disease. The accuracy of the obtained results from the deep learning model was up to 73%. The utilization of AI systems can present a novel approach to addressing daily challenges within the rapidly-evolving world of medicine. Health personnel can take advantage of rapidly changing artificial intelligence and user friendly deep learning models to detect similar future medical concerns.
K-band Absolute Magnitude Relations of Red Clump Stars Separated by Age
Authors: Zhang Tiffany , Spinelli Nicole
Published: February 2024

Red clump (RC) stars form a distinguishable clump on the color-magnitude diagram, making it a good distance indicator. Currently, the two main absolute magnitude estimation methods in the I-band (700–900 nm) conflict: one assumes a constant RC magnitude as supported by empirical data and one relates magnitude with other physical characteristics as supported by theoretical models. Studies attribute these discrepancies to population effects, such as dust, and recommend the K-band (2000–2400 nm) to minimize them. Past studies analyzed relations between the K-band magnitude, color, metallicity, and age, including those stratified by age at 2 Gyr. This study aims to investigate these different relations to clarify trends from past studies, discover new trends, and compare them to similar relations in the I-band. After analyzing cluster RC data from Gaia DR3, 2MASS, and Gaia-ESO DR5, K-band magnitude exhibits insignificant correlation in all relations (p>0.05) but has the greatest dependence and the least root mean square error (RMS) with metallicity in the old RC. Significant correlation was found between I-band magnitude and metallicity for all RC and young RC (p<0.05), especially the latter (R2 = 0.804). This consistency with theoretical trends suggests weaker I-band population effects than previously believed. Overall, these three relations yield more accurate predictions than the mean magnitude. Thus, studies cannot solely rely on the mean K-band or I-band magnitude to estimate distance, and magnitude relations stratified by age can potentially lead to more accurate RC distance estimations and a more accurately calibrated distance ladder.
A Survey of Genetic Risk Factors for Alzheimer’s Disease
Authors: Kamath Aanya
Published: February 2024

This paper surveys a number of discovered genetic risk factors for Alzheimer’s Disease (AD). AD is a neurodegenerative disease characterized by memory loss and cognitive decline. AD is distinguished by large depositions of amyloid-beta (Aβ) protein, known as plaques, in areas of the brain. No single gene has been identified to cause Alzheimer’s, but several risk factors have been identified. Genetic variants associated with the accumulation of Aβ that have been identified as genetic risk factors for AD include APOE-2, APOE-3, APOE-4, APP, PSEN 1, and PSEN 2. This paper discusses these risk factors, their prevalence, how their connection to AD was discovered, and their level of risk.
China's Infrastructure for Resources Model: Case Studies of Bolivia and Argentina
Authors: Davis Zachary , Boelman Bradley , O'Connor Craig
Published: February 2024

China’s Infrastructure-for-Resources (IFR) model is a framework for capital allocation in African infrastructure whereby the loans used to finance projects are repaid through natural resources. The model is designed to combat the resource curse, which is a situation in which a resource-rich country underperforms economically having valuable resources. China has used the IFR model to finance projects throughout Africa, but never in other countries or regions. This research combats this gap by identifying the feasibility of an expansion of the IFR model to Bolivia and Argentina, following the research goal of identifying how much Bolivia and Argentina would benefit from China’s IFR model of foreign direct investment. Case study analysis of Bolivia and Argentina was conducted, including quantitative analysis of economic indicators and qualitative analysis of the country’s geopolitical environment. The model was demonstrated to be minimally beneficial at combating the resource curse in Argentina because while it would provide a much-needed inflation-free alternative to traditional forms of investment, the model would not affect most aspects of the resource curse. In Bolivia, the model was demonstrated to be sufficiently beneficial because of Bolivia’s widespread corruption, which the model combats by transferring the funds to the construction company rather than the corrupt government. For this reason, China should consider expanding the model to Bolivia, and potentially to other countries with similar economic conditions. Looking forward, this research highlights a potential expansion of the IFR model and the possibility for the expansion of models of foreign direct investment in general.
Analyzing the Expansion of China’s Infrastructure for Resources Model Across the Developing World
Authors: Davis Zachary , Boelman Bradley , O'Connor Craig
Published: February 2024

As an alternative to loans from traditional lenders, China has begun to experiment with a financial model known as the Infrastructure for Resources (IFR) model. The IFR model is a model of infrastructure financing in which China sends their workers, equipment, and expertise to the recipient country in exchange for a portion of the future revenue of the resource development project. Despite the promising design of the model, China has only engaged in IFR deals with a few countries, all of which are in Sub-saharan Africa. This research determines the characteristics most in need of the IFR model based on previous literature, and then conducts case studies of one country in every developing region of the world to examine which regions are most in need of the model. For the methodology, quantitative case study analysis was conducted utilizing the economic indicators related to each problematic characteristic the IFR model targets. As for the findings, the best performing regions were Central Asia and Eastern Asia, which were represented by Kyrgyzstan and Mongolia, indicating that the IFR model would be of little benefit to these regions. The worst performing regions were determined to be Southern and Western Asia, which encompass the Middle East, as well as Latin America and the Caribbean. Considering this, China should consider engaging in IFR deals with countries in these regions, as infrastructure improvements would help give the regions the economic jumpstart they need to fuel domestic improvements.
Restaurant Perspectives on the Effects of Point-of-Sale Tip Recommendations on Consumer Patronage
Authors: Beaudette Jack , Koch Tracy
Published: February 2024

This research examines the effectiveness of point-of-sale gratuity recommendations in raising tips within the restaurant industry. Prior field experiments have yielded positive results regarding the impact of point-of-sale gratuity recommendations. However, these studies did not consider the restaurant industry, which is reliant on tips. To address this gap, I conducted a survey of restaurant managers to gauge their perceptions of this technology and compared their responses with prior field study results. Employing a survey approach mitigated resource constraints associated with field experiments. Building on the aforementioned studies, I hypothesized restaurant managers would exhibit positive attitudes toward the utilization of this technology. Survey data underwent chi-square tests of homogeneity to identify variations in responses across restaurant categories. However, limited response rates rendered the chi-square test results inconclusive and thus, not included in the final analysis. Nevertheless, the survey results strongly supported my hypotheses, suggesting that the adoption of point-of-sale gratuity recommendations effectively increases tips received in the restaurant industry. These findings offer insights for future researchers investigating tipping behavior in restaurants. Furthermore, restaurant owners can leverage these results to advocate for implementing point-of-sale tip recommendations, considering the backing from their managerial peers. As the hospitality sector continues to evolve, incorporating this technology can facilitate positive changes in tipping culture, benefiting both businesses and service staff. Future studies should build upon these findings to gain deeper insights into the dynamics of this technology in restaurant settings.
The Interplay of Military Structures and Coups in French-Speaking West African Countries: A Focus on the Presidential Guard
Authors: Allen Ezekiel , Asamoah Elsie
Published: February 2024

This paper examines the interplay between military structures and the prevalence of coups in French-speaking West African countries, with a focus on the destabilizing role of presidential guards. It outlines factors that motivate military interventions against civilian rulers, including perceived corruption, public discontent, military divisions, personal ambitions of top brass, and ideological visions. Comparative analysis explores common drivers and patterns across recent coup attempts in Mali, Burkina Faso, Guinea, and Niger. In many cases, elite, highly-trained presidential guard units and special forces played a pivotal role in decisively ousting leaders by arresting them or providing vital backing to plotters. Their outsized influence within politicized hierarchies enabled them to shape political transitions consistent with institutional interests. Case studies on the 2022 Burkina Faso coup and 2010 Niger coup highlight how presidential guards can both enable and end democratic rule. The paper assesses consequences of seizures of power, typically suspending civil liberties and empowering military factions over institutional control despite initial stability promises. It also examines the inconsistent leverage of regional bodies like ECOWAS and former colonial powers against coup attempts based on security priorities rather than democratic principles. Finally, it outlines reform efforts to deter interventions through security sector changes, governance improvements, early warning systems and constitutional safeguards. However, deeply embedded incentives and capacity for coups persists. The analysis cautions the need for depoliticizing militaries and avoiding the nurturing of specific elite units for regime protection given the risk this poses.

Authors: Amalina Zata Zainina
Published: February 2024

Purpose of this paper: This research aims to analyze the impact of the “burn money” made by Fintech as a means of payment in SMEs that has supported the education to create a cashless society in Indonesia. Methodology: The research uses the literature review method, which is documenting relevant research by quoting authors and years of research. Findings: Consumers can be interested in and ultimately ‘ addicted ‘ to use non-cash payment tools if equipped with various conveniences and benefits. So it can be concluded that the “burn money” strategy conducted by fintech supports the people in Indonesia to form a cashless society. Originality: The importance of conducting a strategy of “burn money” in the form of promotion is important because changing the behavior of consumers is not easy. Limitation: This research only focuses on Indonesia. Fintech is only limited to the three largest Fintech in Indonesia (GOPAY, OVO, and DANA) and focuses on payment services. To conduct further exploration, we can use other methods such as interviews from both the SMEs and the Fintech s in Indonesia to explore or dig deeper into the factors that determine Fintech s to “burn money” to advance the economy of SMEs in Indonesia as a cashless society education.
Microfinance Services and Economic Empowerment of Women Groups in Marginalized Settings in Kenya
Authors: Odunga Robert Mukoswa
Published: February 2024

Women’s economic empowerment globally remains a complex issue with persistent gender disparities in labor force participation, entrepreneurship, and leadership roles. However, microfinance has played a crucial role in bridging this gap by providing women, especially in low-income settings, access to essential financial services. A significant challenge in women’s economic empowerment is the limited access to capital and financial resources that women often face, particularly in marginalized and low-income communities. However, microfinance services have emerged as a solution to address this issue by offering tailored financial services to women who lack access to formal banking systems. This study aimed at assessing the effect of Microfinance services on economic empowerment of women groups in Kilifi County, Kenya. The specific objectives were to determine the effect of micro lending and micro saving services on economic empowerment of women groups. This study was anchored on Access to Capital Theory. This study adopted explanatory research design and targeted a population of 3320 women groups registered by Kenya Climate Innovation Centre (KCIC) in Kilifi County. Simple random sampling techniques and the Krejcie and Morgan t-table was used to sample three hundred and forty-one (341) was derived and primary data was collected by use of a closed ended questionnaire. The collected data was analyzed descriptive methods; and also correlation and regression analysis was conducted. The study revealed that micro lending and micro saving services have a significant positive effect on the economic empowerment of women groups in Kilifi County, Kenya, (P-value=0.017<0.05), and (P-value=0.000<0.05) as their null hypotheses were rejected. This study recommended that women groups should embrace and utilize these micro finance services (micro lending and micro saving) to improve their economic status and their socio-well-being. Similarly, this study recommended that MFIs should increase their outreach by educating women about the various microfinance services available to help women to make informed decisions about which services best meet their needs. This study recommends for a comparative study be undertaken between two or more other empowerment groups, like youth, PWDs, social welfare groups among others.
Contribution of the Common Market for Eastern and Southern Africa in Poverty Alleviation: A Case of Trade Liberalisation in Zambia
Authors: Selisho Joseph , Momba Professor Jotham. C.
Published: February 2024

Background: This study was undertaken due to high levels of poverty in the Common Market for Eastern and Southern Africa (COMESA) Member States. The overall objective of the study was to explore the contribution of COMESA in the fight against poverty in Africa, a case study of Zambia from 2010-2021. The specific objective in this article was to explore the Contribution of the Common Market for Eastern and Southern Africa in Poverty Alleviation, a case of trade liberalisation in Zambia. The study employed qualitative approach with an exploratory research design and critical case sampling to choose 13 key respondents to explore the contribution of the Common Market for Eastern and Southern Africa in Poverty alleviation in Zambia from 2010-2021. Primary data was analysed from 13 key respondents selected purposively using an interview guide to support secondary data. Data was analysed using thematic and content analysis. This study found that COMESA was established by a treaty in December 1994 as a basis for trade liberalisation. The aim of trade liberalisation was to remove tariffs and non-tariff barriers to reduce the cost of doing business to create employment hence contributing to poverty alleviation. Zambia embarked on trade liberalisation and received financial support from COMESA and its international cooperating partners of development to achieve trade liberalisation. The study established that COMESA had been significant in the fight against poverty in Zambia. However, despite the trade reforms implemented, the study established that poverty levels in Zambia had not reduced since 2010 instead there had been an increase from 54.4 % in 2020 to 60.3 % in 2021. Zambia requires a clear regulatory framework predictable for business planning with a conducive legal business environment that promote trade through innovative policy framework targeting various sectors of the economy to generate income activities and employment. There must be regular review of the trade liberalisation rules to ensure coherence and compliance with COMESA rules in order to realise the gains of trade.

Công nghệ bê tông asphalt tái chế nguội là giải pháp công nghệ đem lại nhiều hiệu quả về mặt kinh tế và môi trường do hỗn hợp được sản xuất và thi công ở điều kiện nhiệt độ môi trường. Nhược điểm lớn nhất của hỗn hợp asphalt tái chế nguội là thời gian hình thành cường độ lâu và tính ổn định nước kém. Sử dụng thêm phụ gia xi măng được xem là giải pháp giúp cải thiện thời gian nhũ tương phân tách để hình thành và phát triển cường độ. Do trong thành phần của nhũ tương có nước nên quá trình hình thành và phát triển cường độ của hỗn hợp phụ thuộc vào điều kiện bảo dưỡng.Bài báo này trình bày kết quả nghiên cứu thực nghiệm phân tích vi cấu trúc và thành phần hóa của vữa nhũ tương xi măng-thành phần góp phần tạo nên độ cứng cho hỗn hợp tái chế nguội. Hàm lượng xi măng được lựa chọn thí nghiệm lần lượng là 0%, 1,5% và 2,5%.Thời gian bảo dưỡng hỗn hợp vữa nhũ tương sau khi trộn với xi măng lần lượt là 1 ngày, 7 ngày,14 ngày và 28 ngày. Kết quả cho thấy rằng, với cùng tỉ lệ xi măng khi tăng nhiệt độ và thời gian bảo dưỡng lên thì xi măng thủy hóa nhanh hơn và các sản phẩm thủy hóa hình thành nhiều hơn. Ở nhiệt độ bảo dưỡng như nhau, tỉ lệ xi măng khác nhau cũng ảnh hưởng đến tỉ lệ các sản phẩm thủy hóa và sự phát triển của tinh thể calcium silicate hydrate (3CaO.2SiO2.3H2O – C3S2H3)

Purpose: The purpose of the study was to examine if aflatoxin was related to child stunting in the study areas of two counties in Eastern Kenya. The objective of this study was to examine the relationship between aflatoxin and stunting in children 6 to 59 months. The study presents a question of aflatoxin as a contaminant of staple foods for children and therefore an “underlying factor” contributing to stunting outcome in children in affected study areas. A multi-stage field survey was carried out at county and household level.

Methodology: Data were collected at household level by research assistants using a smart phone which had geo-positioning that enabled data verification by supervisors. Food samples of local maize-flour and other cereals were collected and analyzed in the laboratory for aflatoxin contamination.  Data was analyzed using SPSS Version 21.  Analysis of factors that contribute to stunting raises an important question on the underlying possibility of aflatoxin.

Findings: Findings revealed a significant relationship was established between breastfeeding and stunting through ANOVA p/> 0.017 (t –value -2.810 and robust standard error of 0.5131 and coefficient value of -1.4411).  Aflatoxin levels from samples of maize grain, flour mixes and animal feed collected was 17.8% of toxicity above national and regional safe margin of 10ppb.

Unique contributor to theory, policy and practice: Key interventions including farmer education and sensitization as well as use of aflasafe in the soil to reduce aflatoxin in the region are recommended.

The Dramatic increase in the traffic flow raises demand on innovative technologies that can improve safety and efficiency of transportation systems. Road safety can be substantially enhanced by the deployment of wireless communication technologies for vehicular networks, which enable new services such as collision detection traffic management, and further communication facilities between moving vehicles. Aiming at providing reliable wireless communications for vehicular networks the RF communication will serve as an underlying protocol for future inter-vehicular applications worldwide. This paper presents an implementation of a complete vehicle to vehicle communication, designed according to the specification. In addition to this a blind spot detection system for protection against misshapen like vehicle collisions that causes loss of human lives is being implemented. The blind spot detection system will be useful while changing the lane. Ultrasonic sensors, Raspberry pi, RF module and GPS modules are used to implement the complete design The main aim of V2V communication is to prevent accidents by allowing vehicles in transit to send position and speed data to one another. The vehicle’s driver may simply receive a warning should there be a risk of an accident or the vehicle itself may take preemptive actions as braking to slow down.

Introduction

Lipoprotein(a) [Lp(a)] is a strong, genetically determined, pathogenetic factor of atherosclerotic cardiovascular disease (ASCVD). The aim of this post-hoc analysis was to compare the effect of hypolipidemic treatment on Lp(a) levels of patients with mixed hyperlipidemia.

Material and methods

We previously randomized patients with mixed hyperlipidemia (low-density lipoprotein [LDL-C] > 160 mg/dl and triglycerides > 200 mg/dl) to rosuvastatin monotherapy 40 mg/day (R group, n = 30) or rosuvastatin 10 mg/day combined with fenofibrate 200 mg/day (RF group, n = 30) or omega-3 fatty acids 2 g/day (RΩ group, n = 30). In the present post-hoc analysis, we included only the patients whose Lp(a) levels were assessed (16, 16 and 15 in the R, RF and RΩ groups, respectively). Lipid profile and Lp(a) were measured at baseline and after 3 months of treatment.

Results

Significant reductions in total cholesterol, LDL-C, non-high-density lipoprotein-cholesterol (non-HDL-C) and triglyceride levels were observed in all groups. A significant increase in Lp(a) levels was noted in the R (p = 0.017) and RF (p = 0.029) groups, while no significant difference was seen in the RΩ group (p = NS). Regarding Lp(a) elevations, no differences were found between groups. In the R group, a strong negative correlation between the changes in Lp(a) and LDL-C (r = –0.500, p = 0.049) was observed, while a significant negative correlation between the changes in Lp(a) and triglycerides (r = –0.531, p = 0.034) was noted in the RF group.

Conclusions

Rosuvastatin and/or fenofibrate treatment increases Lp(a) levels in patients with mixed hyperlipidemia. Novel therapies should target Lp(a) level reduction to decrease the residual ASCVD risk in patients with mixed hyperlipidemia.

The aim of this case report is to present a 53-year-old female with retinal detachment in the right eye and retinoschisis in the left eye. Early detection of the retinal detachment and surgical treatment allowed to keep the full visual acuity many years after the incident. Dilated fundus examination revealed peripheral retinoschisis in the second eye. Prophylactic laser photocoagulation was applied to avoid the potential risk of retinal detachment. This case presents the current state of knowledge related to retinoschisis, possible complications and available methods of treatment.

Published: February 2024

Uveitis is a significant civilizational issue contributing to a substantial decline in the quality of life. Its etiology is complex, ranging from autoimmune to infectious causes. The Posner-Schlossman Syndrome is characterized by recurring episodes of inflammation of the anterior segment of the uvea and elevated intraocular pressure. Although traditionally classified as secondary open-angle glaucoma, its etiopathogenesis has not been fully elucidated. Understanding it is essential to apply effective treatment and maintain proper vision.

Authors: Prokopiuk Agata , Mackiewicz Jerzy
Published: February 2024

Purpose

To present preliminary results of distance, intermediate and near visual acuity, objective and manifest refraction in two groups of patients: targeted on emmetropia and targeted on small myopia after cataract surgery with an implantation of Extended Depth-of-Focus AcrySof® IQ Vivity® DFT015 (Alcon Inc., Fort Worth, TX, USA) intraocular lens in three months follow-up.

Material and Methods

A total of 18 eyes of 15 patients underwent 2.4 mm coaxial cataract surgery with an implantation of AcrySof® IQ Vivity® DFT015 intraocular lens (Alcon Inc., Fort Worth, TX, USA). Before surgery best-corrected distance visual acuity, objective and manifest refraction and corneal keratometry were evaluated. Three months after the surgery uncorrected and best-corrected distance visual acuity, uncorrected intermediate visual acuity uncorrected and best-corrected near visual acuity, objective and manifest refraction and corneal keratometry were analyzed in both groups.

Results

Three months after the surgery in the emmetropic group refractive outcomes were: mean uncorrected distance visual acuity 0.04 ± 0.05, mean best-corrected visual acuity 0.01 ± 0.04, mean uncorrected intermediate visual acuity 0,01 ± 0,03, mean uncorrected near visual acuity 0.15 ± 0.09 and mean best-corrected near visual acuity 0.00 ± 0. In the mini monovision group: mean uncorrected distance visual acuity was 0.13 ± 0.11, mean best corrected visual acuity 0.01 ± 0.02, mean uncorrected intermediate visual acuity 0.00 ± 0, mean uncorrected near visual acuity 0.09 ± 0.13 and mean best-corrected near visual acuity 0.00 ± 0. There was no significant change in corneal keratometry in flat and steep meridian (p = 0.59 and p = 0.4) in whole group. There were no intra- and post-operative complications in any of the patients.

Conclusions

AcrySof® IQ Vivity® DFT015 (Alcon Inc., Fort Worth, TX, USA) provided good distance and intermediate visual acuity with the functional near. It is well tolerated with poor impact of post-operative optical phenomena. Significant gains in binocular near vision can be achieved by leaving the nondominant eye of patients with 0.50 D to 1.00 D of myopia.
