Purpose of this study is to compare the ocular functional changes including pupil size, visual acuity, depth of focus, accommodative amplitude, visual field, contrast sensitivity, and stereopsis induced by multiple and single pinhole glasses, in addition, to check reading speed and survey for ocular discomfort after using both pinhole glasses.
Objective measures of health are relatively expensive; meanwhile, self-reports are critiqued to be subjective and not comparable. A middle ground approach is to apply the frontier work of vignette methods. The aim of the survey experiment is to explore the validity of survey instruments to identify students who need glasses, using objectively measured visual acuity as a gold standard. It is hypothesized that direct comparison against vignette (DCV) is significantly different fr...
Two-month randomized trial comparing three groups: (November 2015 - January 2016).
WELBOW study is an international, ambispective and prospective, single arm, multicenter, observational, non-comparative, Post-Market Clinical Follow-up (PMCF).

Decades of psychological research has highlighted the impact of visual perception on mood and happiness. The investigators hypothesized that literally seeing the world through rose colored glasses may have an effect on perception, mood, and happiness. After cataract surgery, which classically increases the vividness of perceived colors, patients report significant satisfaction. The investigators therefore sought to explore whether using pink colored lenses leads to a measurable...
This study is designed to evaluate the effectiveness of a novel amblyopia treatment - Intermittent occlusion therapy (IO-therapy) glasses (AmblyzTM) in treating severe amblyopia. Children ages 3 to 8 years with severe amblyopia (visual acuity of 20/100 to 20/400 in the amblyopic eye) will be enrolled and randomized into two groups: 1) standard 6-hour patching group or 2) 12-hour IO-therapy glasses group.
This project is designed to test a lightweight, portable, computerized pair of glasses that will help reduce some of the cognitive deficits seen in patients who have suffered damage to their right cerebral hemisphere.
Cryo AF Global Registry a prospective, global, multi-center, observational Post-Market Registry
The purpose of this cohort post market registry is to collect data and create a global database on use of embolization devices and embolization procedures outcome. The data collected in the cohort will serve a scientific purpose to acquire better insight in embolization procedures. This will be achieved by publications in Scientific Journals and by presentations at scientific meetings. Additionally it will support the industry on creating a better overview of the products used ...
The issue of uncorrected Presbyopia is an emerging health and livelihoods problem in Bangladesh. Presbyopia is easily corrected with an appropriate pair of reading glasses. Non-governmental organizations and government agencies have been working in many emerging markets, including Bangladesh, to increase eyeglass coverage among low-income adults by introducing basic vision screening and the dispensing of reading glasses at the community level. While vision screening is typicall...
Observational, Non-Interventional, Prospective, Post Market Surveillance & Post Market Clinical Follow up, International, Medical Registry to Confirm the Safety and the Performance of the Anecova Intra Uterine Culture Device
This study is designed to generate a comprehensive survey of the use on the market of the Anecova device within its intended indications according to the Instructions For Use. The Anecova Registry is part of the Anecova quality system, to enable the Post Marketing Surveillance and the Post Market Clinical Follow-up.
The objectives of this survey are to collect data to report the safety and efficacy of Firazyr (Icatibant acetate) in the post-marketing phase in participants diagnosed with Hereditary Angioedema (HAE).
THAOS is a global, multi-center, longitudinal observational survey open to all patients with transthyretin-associated amyloidoses (ATTR), including ATTR-PN (polyneuropathy), ATTR-CM (cardiomyopathy) and wild-type ATTR-CM. It is open-ended with a minimum duration of 10 years. Patients will be followed as long as they are able to participate. The principal aims of this outcome survey are to better understand and characterize the natural history of the disease by studying a la...
One of the most challenging aspects of Pediatric Dentistry is the management of child behavior. Among the procedures performed, local anesthesia is one of the factors that influence the increase in fear and anxiety in children in relation to dental procedures. This study aims to evaluate the effect of the use of virtual reality glasses as an audiovisual distraction technique during anesthesia in behavior, anxiety and pain perception, comparing it with traditional behavior manag...
Global Post-Market Study of the VenaSeal™ Closure System in the Treatment of Early and Advanced Stage Superficial Venous Disease.
The primary objective of the study is to evaluate the effect of smart glasses (Head-mounted display Moverio BT-300 (Epson Inc., USA)) on the first-attempt success rate of radial artery cannulation in pediatric patients. This study hypothesizes that the use of smart glasses improves the hand-eye coordination and the first-attempt success rate of radial artery cannulation. This is a single-center, randomized, placebo-controlled study comparing the real-time ultrasound image throu...
Non-pharmacological interventional pilot study on the effect of prismatic glasses for the improvement of Pisa syndrome in Parkinson's disease. The study involves 40 patients, of whom 20 receive active treatment and 20 slow placebo. At the end of the study, all patients receive corrective lenses in compassionate use if the study yields positive results.
Evidence suggests that student athletes frequently experience sleep problems and are aware of the impact of sleep loss on mental and physical outcomes. As such, student athletes are motivated to improve sleep quality in order to improve their outcomes for overall athletic performance. This study will consist of two parts. The first part will be a survey. Fall athletes arrive in the summer, and Part 1 will invite 200 of these athletes to complete a survey within the first week o...
At the Aravind Eye Hospital (AEH) in Madurai, India, patients ages 18-40 receiving treatment for refractive error who choose to enroll in the study will be evaluated using subjective refraction and objective refraction, by way of the QuickSee autorefractor. Patients will then be randomized into one of two treatment plans: receive glasses from objective measure first then subjective measure second, and vice versa. After one week of wearing the first pair of glasses, patient pref...

This is a study to investigate efficacy of over-glasses patch treatment for amblyopic children using visual function improvement and Amblyopia Treatment Index (ATI) changes.
Chinese children are some of the most short-sighted in the world, but only one in five children in poor areas who needs glasses has them. Our team has already shown in other trials that giving children free glasses leads to better grades and that free glasses have a bigger impact on grades than factors like parents' education level and the amount of money a family has. The effect on grades from glasses is greater than from other health services in school, like giving vitamins. ...
