AbstractTo assess the safety of cosmetic contact lenses and to identify other factors of contact lens (CL)-related complications for Japanese females. A web-based, cross-sectional, observational survey of complications related to CL use was performed. The frequencies of complications were compared between transparent and cosmetic CLs. Besides lens pigmentation, age, replacement schedule, total experience, daily wear time, location of purchase, stacking of CLs, CL exchange with friends, compliance to hygiene procedure, replacement of CLs at intervals longer than recommended, and CL wear overnight were considered as risk factors. Logistic regression analyses were performed to calculate the odds ratios. A total of 3803 Japanese females were analyzed. The frequency of adverse events was 33.4% (95%CI 31.3–35.4%) and 35.7% (95%CI 33.5–38.0%) for transparent and cosmetic CLs, respectively. In a multivariate model, statistically significant factors associated with complications included the following: quarterly schedule lenses, replacement at intervals longer than recommended, compliance to hygiene procedure, overnight wearing, purchase at physical shops and on the internet, and longer daily wearing time. Most of the risk-increasing behaviors are preventable. The role of public health ophthalmology is to increase awareness and to improve CL use behaviors.

Abstract Objectives:To compare the frequency of contact lens (CL)-related complications and to identify the risk factors for transparent and decorative CL users. Methods:A web-based, cross-sectional, observational survey of adverse events related to CL use was performed. The frequencies of complications were compared between two groups. Logistic regression analyses were performed to calculate an odds ratio (OR) for each metric. Age, replacement schedule, total experience, daily wear time, location of purchase, stacking of CLs, CL exchange with friends, compliance to hygiene procedure, replacement of CLs at intervals longer than recommended, and CL wear overnight were considered as confounders. Results:A total of 3,803 Japanese females were surveyed. The frequency of adverse events was 33.35% (95%CI: 31.27%-35.43%) and 35.73% (95%CI: 33.53%-37.98%) for transparent and decorative CLs, respectively. In a multivariate model, statistically significant factors associated with complications included the following: quarterly schedule lenses, replacement of CLs at intervals longer than recommended, compliance to hygiene procedure, CL wear overnight, CL purchase at physical shops and on the internet, and longer daily wearing time.Conclusions:Most of the risk-increasing behaviors are preventable. The role of public health ophthalmology is to increase awareness and to improve CL use behaviors.

Objective: The purpose of our research is to emphasize the role of underestimated predisposing conditions for microbial keratitis in contact lens users, to draw attention to the complications of wearing contact lenses without ophthalmic examination, and to offer a short questionnaire for fast and easy estimation of the risk factors for bacterial keratitis. Methods: A series of 23 cases of healthy young individuals, treated for bacterial keratitis, provoked а research on the predisposing factors for its development. Results: 55% of the patients had started to wear contact lenses without specific examination. 75% had made mistakes in the hygiene and storage of the lenses. We identified risk factors for development of bacterial keratitis in all cases. Conclusions: A thorough anamnesis and ophthalmic examination are crucial in decision making about contact lens wearing because they could reveal some of the predisposing conditions for the occurrence of ocular complications. The usage of contact lenses without a prescription poses health risks and could have a negative impact on the social and healthcare system.

Aim: It has been observed that potential beneficiaries rarely request for alternatives to corrective eyeglasses in our setting. The objective of this study was to determine awareness and attitude towards alternatives to spectacle correction, specifically; contact lens and refractive eye surgery among spectacle wearers in a resource-limited setting.Methods: A cross-sectional survey of 214 spectacle wearers in seven Nigerian hospitals using semi-structured questionnaire. Information sought included demographic characteristics, awareness, and attitudes to contact lens and refractive eye surgery as well as reasons for the poor interest in alternatives to eyeglasses.Results: There were 93 males and 121 females, with a mean age of 40.2 years (SD 15.8.). Most, 198 (92.6%) had at least secondary education. Ninety-eight (45.8%) and 113 (52.8%) patients were aware of the options of contact lens and refractive eye surgery respectively, but 171 (80%) were averse to wearing contact lenses or having refractive eye surgery. Reasons given included lack of information, high cost, and possible complications that may arise. Higher education was significantly associated with participants’ awareness of alternatives to eyeglasses (contact lens [P = 0.016], refractive eye surgery [P=0.009]) but not with willingness to use contact lens (P = 0.96) or refractive eye surgery (P = 0.425).Conclusion: There was relatively high awareness but low willingness to use alternatives to corrective eyeglasses among users. Education on alternatives to corrective eyeglasses, allaying fears on their complications, and making them more affordable could enhance awareness and create a more positive attitude towards them.

Background: Despite the significant role of nurses in end-of-life care, their attitudes towards euthanasia are under-represented both in the current literature and the controversial debate that is ongoing in several countries. Research questions: What are the attitudes towards euthanasia among Finnish nurses? Which characteristics are associated with those attitudes? Research design: Cross-sectional web-based survey. Participants and research context: A total of 1003 nurses recruited via the members’ bulletin of the Finnish Nurses Association and social media. Ethical considerations: Ethical approval was obtained from the Committee on Research Ethics of the university to which the authors were affiliated. Findings: The majority (74.3%) of the participants would accept euthanasia as part of Finnish healthcare, and 61.8% considered that Finland would benefit from a law permitting euthanasia. Most of the nurses (89.9%) thought that a person must have the right to decide on his or her own death; 77.4% of them considered it likely that they would themselves make a request for euthanasia in certain situations. Discussion: The value of self-determination and the ability to choose the moment and manner of one’s death are emphasized in the nurses’ attitudes towards euthanasia. Conclusion: A continuous dialogue about euthanasia and nurses’ shared values is crucial due to the conflict between nurses’ attitudes and current ethical guidelines on nursing.

Introduction: Contact lenses are increasingly being used for cosmetic or therapeutic purposes, followed by subsequent contamination and complications such as keratitis. The lens case is one of the most common places to find the cause of contamination. Objectives: This study was designed to evaluate the health behaviors affecting the lens case contamination and its relationship with the result of lens case culture which can help in prevention of complications. Patients and Methods: In this cross-sectional study that was performed in northwest of Iran, 150 asymptomatic participants were assessed for health behaviors affecting the lens case contamination and their lens cases were sampled for culture and antibiogram. Data were analyzed with SPSS-16 software. Results: The frequency of positive microbial culture in medical and cosmetic contact lens cases was 30.7% and 66.8%, respectively and 32.7% in general. Among the isolated bacteria observed in positive cultures, Alcaligenes,Enterobacter aerogenes, gram-positive Diphtheroid bacilli, Pseudomonas aeruginosa and Staphylococcus epidermidis were the most common microorganisms, respectively. Conclusion: A significant proportion of contact lens cases, especially those used for cosmetic purposes had bacterial contamination. Failure to replace the lens case for more than 9 months and the mismatch of the lens solution brand with its storage case will increase bacterial contamination. Washing the lens case with soap and water, and drying it after washing, will reduce bacterial contamination.

Background: Refractive error is the most common cause of correctable visual loss worldwide. Decreased vision due to refractive error can be easily corrected with the help of spectacles, contact lenses and refractive surgery. However, there are 42% of uncorrected refractive errors all over the world. The present study aimed to evaluate different kinds of refractive errors, its prevalence and pattern in patients from rural areas who visited our hospital in the last five years. Material and Methods: This cross-sectional study enrolled 2,138 patients, who visited eye OPD at Rawal Institute of Health Sciences, Islamabad during a period of five years i.e. from September, 2013 to September, 2018. Patients having only refractive error with an age of five years and above were included in the study.  All patients had objective refraction with automated refractometer followed by subjective refraction. Data was entered and analyzed in SPSS version 20.0. Chi-square test was used for comparing groups with a P-value of <0.05 considered as statistically significant. Results: Compound myopic astigmatism was the most common error found in our study population (n=575; 26.9%). The second most frequent complaint was simple myopia (n=501; 23.4%) followed by presbyopia (n=441; 20.6%) and mixed astigmatism (n=235; 11%). Patients with more than one refractive error included 178 (8.3%) with mixed astigmatism and presbyopia and 78 (3.6%) with simple myopia and presbyopia. Compound myopic astigmatism was more prevalent in younger ages compared to older age groups (46.4% vs 19.9%) (P <0.001). Mixed astigmatism (12.4% vs 8.9%), simple myopia (23.8% vs 22.9%) and presbyopia (21.3% vs 19.5%) were slightly greater in females than males (P=0.07), respectively. Conclusions: The prevalence of myopia is significantly higher among female population and young individuals. Mixed astigmatism combined with presbyopia is more common among elderly population.

Background To date, there are no data available on the safety of COVID-19 vaccines in Latin American patients with Multiple Sclerosis (MS). Objective Characterize safety of COVID-19 vaccines in Latin American (LATAM) patients with Multiple Sclerosis (pwMS). Methods A cross-sectional study between February 1, 2021, and April 30, 2021. Individuals with MS from LATAM countries were invited to participate in a self-administered web-based survey, through MS patient organizations from the region. Results 393 vaccinated pwMS from 10 different Latin American countries were included. The vaccines administered were: inactivated virus vaccines (IVV) in 38.2% of patients, adenovirus vector vaccines (AdV) in 48.8% and mRNA vaccines 13%. All patients received at least one dose of any of the COVID-19 vaccines and 123 (31.3%) declared receiving a second dose. Mean (SD) age 41.5 (11.8) years, 82.4% female, MS disease duration: 8.4 (8.2) years. No serious adverse events were reported with any of the COVID-19 vaccines after either the first or second dose. A lower frequency of adverse events was found with IVV (22%) in comparison with AdV (46.4%) and mRNA (35.3%) ( p < 0.01). Five participants reported having an MS relapse after IVV first dose. Conclusion COVID-19 vaccines applied in LATAM proved safe for MS patients.

Purpose: To assess the contact lens compliance rate by using a self-administrated validated questionnaire, the level of awareness, compliance & detectable behavioral changes, patterns or trends in contact lens users. Methods: A questionnaire ,Cross sectional prospective study to understand the compliance in contact lens wearers, the questionnaires were distributed randomly among the users at various clinical & optical outlets. Based on various studies, and taking into account time constraints the sample size of 40 was taken. The mean age of 24 years was taken without any ocular pathology and systemic disease affecting the ocular health. Result: The majority of 87% of the subjects studied, preferred the monthly modality and 13 % preferred conventional yearly replacement lenses. Considering average duration of wear 64% of the subjects showed non- compliance and prolonged their wearing schedules beyond 8 hours. 38% of the contact lens users were not taking optimum care of the lens cases. A majority of 50% of the subjects rated better cosmetic appearance the most important factor, while 25% of them rated cosmetic & better vision equally important. 68% knew the availability of extended wear contact lenses that can be worn during sleep. Optical outlets are the places where the patient is more motivated for soft contact lens. Conclusion: Cost and convenience are two factors that must be considered when educating patients about proper lens care regimens. In addition, compliance is more likely if the patient is satisfied with the medical visit.

Lubrication Characteristics

It is popular to wear the contact lens nowadays. Also, the output value of the contact lens is estimated more than 4 billion NT dollar every year. Because the phenomena of the contact lenses are very complicated, the relevant mechanisms are not well understood. Thus, the security of contact lens needs to be further investigated. In the lubricated mechanism of the contact lens, there is a layer of tear between the contact lens and cornea. The contact lens’ behavior is akin to that of a slider bearing. The lens represents the slider, the eye plays the role of the stationary pad, and the tear film is the lubricant. Hence, hydrodynamics and contact mechanisms of a contact lens are quite a fascinating subject that is relevant to the science of tribology. In the paper, the lubrication mechanisms include the partial hydrodynamic lubrication (contact lens roughness), contact mechanics and Newtonian fluid mechanics have been established. The parameters of roughness, flow factor, tear film geometry, and hydrodynamic pressure distribution are discussed. The developed technology increases the safety of contact lens.
