Abstract: Visual acuity is the ability of a person's eyes to distinguish the shapes and details of objects at a certain distance. Decreased visual acuity is still a health problem in society. A person's visual acuity is influenced by refraction, pupil size, light intensity, exposure time, retinal stimulation area, eye adaptation, and eye movement. The use of smartphones has become a necessity of everyday life in society. Several studies have shown that smartphone use can lead to decreased visual acuity. This study aimed to determine whether there is a relationship between smartphone use and visual acuity and the factors that can affect visual acuity due to smartphone use. The research design used was a literature review with journals that can be accessed free full text through PubMed and ClinicalKey. As a result, the smartphone use can lead to DED, myopia, dan blurred vision. In conclusion, there is a relationship between smartphone use and visual acuityKeywords: smartphone, visual acuity  Abstrak: Ketajaman penglihatan adalah kemampuan mata seseorang untuk membedakan bentuk dan detail objek pada jarak tertentu.

Digital Detox

Smartphone use, e.g., on social network sites or instant messaging, can impair well-being and is related to clinical phenomena, like depression. Digital detox interventions have been suggested as a solution to reduce negative impacts from smartphone use on outcomes like well-being or social relationships. Digital detox is defined as timeouts from using electronic devices (e.g., smartphones), either completely or for specific subsets of smartphone use. However, until now, it has been unclear whether digital detox interventions are effective at promoting a healthy way of life in the digital era. This systematic literature review aimed to answer the question of whether digital detox interventions are effective at improving outcomes like health and well-being, social relationships, self-control or performance. Systematic searches of seven databases were carried out according to PRISMA guidelines, and intervention studies were extracted that examined timeouts from smartphone use and/or smartphone-related use of social network sites and instant messaging. The review yielded k = 21 extracted studies (total N = 3,625 participants). The studies included interventions in the field, from which 12 were identified as randomized controlled trials. The results showed that the effects from digital detox interventions varied across studies on health and well-being, social relationships, self-control, or performance. For example, some studies found positive intervention effects, whereas others found no effect or even negative consequences for well-being. Reasons for these mixed findings are discussed. Research is needed to examine mechanisms of change to derive implications for the development of successful digital detox interventions.

Iris Claw

A 38-year-old patient presented to us with complaints of blurred vision and photophobia in the left eye with an uncorrected visual acuity of 20/400, improving to 20/60 with pinhole. The patient underwent phakic iris-claw lens surgery 15 years ago for high myopia. On examination, there was anterior chamber rigid phakic iris-claw lens along with complicated cataract. We planned for sutureless self-sealing 6.5 mm sclerocorneal tunnel for explantation of rigid phakic iris-claw lens along with cataract extraction with irrigating vectis. There was postoperative reduction in astigmatism due to incision planned on steep axis, and visual acuity improved to 20/30 uncorrected. This technique provides significant advantages from the previously described techniques in terms of decreased postop astigmatism, no need for sutures, no issues of chamber instability and iris trauma and without the need for phacoemulsification.

Multiresistant Strains

The indiscriminate use of antimicrobials in clinical and surgical routine is an upward reality among veterinarians. The emergence of multiresistant strains is one of the consequences of the irrational use of these drugs, causing an emergency worldwide health problem. By 2050, it is estimated that superbugs will kill about 10 million people worldwide, more than cancer. This paper aims to conduct a literature review on the topic and raise awareness of health professionals about the importance of rationality in the act of choosing the antimicrobial to be used, as well as assess the need or not to use them

Spatial ability is an important one of the abilities for completing many tasks in everyday life successfully. Spatial ability is considered a type of different ability to others. Therefore, there needs a study on how are the characteristics of spatial abilities and to develop in schools. This paper is to reveal the ways are developing spatial abilities in learning mathematics. Based on literature review from some research, at least that there are six ways to develop spatial abilities in learning mathematics, namely: (1) using spatial language in daily interactions; (2) teaching for sketching and drawing; (3) using a suitable game; (4) using a tangram; (5) using video games; and (6) origami and folding paper. Playing video games like Tetris are exercises for spatial relations, mental rotation, spatial orientation, and spatial visualization.

The Impact

The purpose of this study is to describe and reveal the impact of excessive smartphone use, which then leads to phubbing. This research study was conducted in May 2020 on 30 students of Uin Sunan Kalijaga as respondents or research subjects. This type of research is qualitative research and interviews with all research subjects, and literature review. The results of the study were recorded that 92% of 27 respondents revealed that a phubber did not give appreciation and was more likely to underestimate the other person. So, planting and practicing Pancasila values in everyday life is very important to carry out. This is so that each individual can fortify and organize himself against wise smartphone use. Then it is hoped that through this research study, students as the nation's next generation will realize the impact of excessive smartphone use on social life.

Sleep has been found to have a beneficial effect on memory consolidation. It has furthermore frequently been suggested that sleep does not strengthen all memories equally. The aim of this literature review was to examine the studies that have measured whether sleep selectively strengthens certain kinds of declarative memories more than others, depending on such factors as emotion, reward, test-expectancy or different instructions during encoding. The review of this literature revealed that although some support exists that sleep is more beneficial for certain kinds of memories, the majority of studies does not support such an effect. A second aim of this review was to examine which factors during sleep that have been found to selectively benefit certain memories over others, with a special focus on the often-suggested claim that rapid eye movement sleep primarily consolidates emotional memories. The review of this literature revealed that no sleep variable has been reliably found to be specifically associated with the consolidation of certain kinds of memories over others.

Corneal Laceration

Background: Nd:YAG capsulotomy is the treatment of choice for posterior capsular opacification after cataract surgery. We report a case of corneal perforation following Nd:YAG capsulotomy in a patient with systemic scleroderma. Case Presentation: A 69-year-old woman presented with acute onset of blurred vision 2 weeks following Nd:YAG laser capsulotomy for posterior subcapsular opacification. On examination, her best-corrected visual acuity was 1/120, and bio-microscopy revealed a central full-thickness corneal laceration. Conservative treatment consisted of topical ocular antibiotics, cycloplegics, hypotensive drops and a soft therapeutic contact lens. Her final visual acuity improved to 6/18 with resolution of the corneal laceration. Conclusion: The possibility of corneal perforation after Nd-YAG capsulotomy in patients with systemic scleroderma and connective tissue disease should be borne in mind when treating such patients.

Appropriate medical management can be an alternative in those patients with submacular cysticercosis in whom achieving good visual outcome with vitreoretinal surgery is not possible. We report the case of a 25-year-old female who presented complaining of blurred vision in her left eye associated with photopsias and metamorphopsias of 3 months duration. Initial visual acuity in the right eye was 20/20 and 20/100 in the left eye. Upon indirect ophthalmoscopy in the left eye, a yellow-white, dome-shaped, elevated lesion with foveal involvement was observed. The rest of the ophthalmological examination proved normal. With clinical findings and images, submacular cysticercosis was diagnosed, and vitreoretinal surgery was suggested. Nevertheless, the patient did not accept the treatment; therefore, medical management was initiated. Central nervous system involvement was ruled out, and treatment with praziquantel and systemic prednisolone was initiated. Cysticercosis was resolved with significant improvement of her symptoms and visual acuity.
