“…This finding suggests that the early introduction of the VRPS into a study program is warranted, as introduction late in training yields equivocal transitional outcomes. 29 The findings are consistent with studies in other areas of health-care that describe the importance of virtual programs in the development of understanding, confidence and performance. 16,18,19,35,36 This report adds to the limited literature on simulation-based medical education in eye-care training, and on translational clinical performance outcomes.…”

The Virtual Refractor has many features of high-fidelity medical simulation known to lead to effective learning and it also offers flexible independent learning without a concomitant increase in the student time-burden. The improved accuracy and speed on first patient encounters found in this study validates the use of this patient simulator as a useful bridge for students early in training to successfully transfer theoretical knowledge prior to entering the consulting room. The translational benefits resulting from compulsory learning activities on a patient simulator can lead to reduced demands on infrastructure and clinical supervision.

“…However, face validity (the outward appearance) was relatively low and prompted a corporate-funded online version by the Brien Holden Vision Institute, first available in Asia, and then worldwide from 2015. 27 There has been only one reported study on the use of the VRPS, 29 which questioned its efficacy when instigated late in the training of optometrists.…”

“…Subjective refraction technique, which relies on a participant's feedback, involves placing a series of trial lenses before the eye until a clear retinal image is perceived by the participant. 20 Near vision was then assessed monocularly over distance refractive correction using a near Snellen chart, held at 40cm from the participants' eyes. A near version of the tumbling 'E' chart was used to assess the near visual acuity of illiterate participants.…”

Abstract:Purpose: To determine the near vision spectacle coverage and barriers to obtaining near vision correction among adults aged 35 years and older in the Cape Coast Metropolis of Ghana. Methods: A population-based cross-sectional study design was adopted and 500 out of 576 participants aged 35 years and older were examined from 12 randomly selected clusters in Cape Coast, Ghana. All participants underwent a comprehensive eye examination which included: distance and near visual acuities measurements and external and internal ocular health assessments. Distance and near refractions were performed using subjective refraction technique. Information on participants' demographics, near vision correction status, near visual needs and barriers to acquiring near vision correction were obtained through a questionnaire administered as part of the study. Results: The mean age of participants was 52.3±10.3 years of whom 280 (56%) were females and 220 (44%) were males. The near vision spectacle coverage was 25%, 33% "met need" for near vision correction in the presbyopic population, and 64% unmet need in the entire study population. After controlling for other variables, age (5 th and 6 th decades) and educational level were associated with "met need" for near vision correction (OR=2.7 (1.55-4.68), p =0.00, and OR=2.36 (1.18-4.72), p=0.02 respectively). Among those who needed but did not have near vision correction, 64 (26%) did not feel the need for correction, 55 (22%) stated that they were unaware of available interventions, and 53 (21%) found the cost of near vision correction prohibitive. Conclusion: There was a low near vision spectacle coverage in this population which suggests the need for strategies on health education and promotion to address the lack of awareness of spectacle need and cost of services.

“…Add up the converted responses for each participant and multiply that total by 2.5 to convert the range of possible values from 0 to 100. The results indicate a similar pattern of the user behavior, meaning that proposed apps could help user to measure the diopter level with 100% success rate, considering the total time for performing each scenario condition, participants completed the experiment task considerably fast with proposed application (Mean=2.03 minutes, Min=1.6 minutes, and Max=3.1 minutes) when compared to the average time taken when conduct clinical refraction measurement [34]. The total SUS score is more than 80, meaning that the overall performance of this prototype is excellent to user [35].…”

The diopter is the unit of measurement for the refractive power of a lens. Myopia is a form of refractive error which is a leading cause of visual disability throughout the world. The prevailing treatment of refractive errors which are commonly used in daily life are glasses and contact lenses. Although those methods can overcome myopia, many myopia patients still don't really know how to measure their current refractive error in diopter. This condition may retard the progression of refractive treatment in the myopic individual. The common methods to measure refractive error are phoropter with Snellen chart and retinoscopy, but those expensive tools need expertise to operate. This paper presents the concept of measure the face to smartphone screen distance to provide the possibility to implement a mobile application as a low-cost alternative refractive measurement tool. The main objective is to investigate the feasibility of mobile application to help patients with myopia measuring their blur line distances and evaluate their diopter levels independently. The experimental results reveal that, with 80.5 usability score the overall functionality of proposed application can be categorized as usable to users and feasible for future implementation.

The influence of a novel simulated learning environment upon student clinical subjective refraction performance: A pilot study

Abstract: Short-term exposure to a SLE can positively influence clinical subjective refraction outcomes for less experienced optometry students and may be of benefit in increasing the skills of novice refractionists to levels appropriate for commencing supervised clinical interactions.
