Observational Survey Study on the Impact of Myopia and Its Complications on Quality of Life.

Group 1 respondents' assessment of EQ-5D-Y-3L (proxy)

Group 1 respondents are parents (or other proxy) of children and adolescents suffering from myopia. The EQ-5D-Y-3L (European Quality of Life 5 Dimensions 3 Level) proxy version is an instrument used to assess health-related quality of life (HRQoL) of children and adolescents from the perspective of a parent, caregiver or another proxy. It uses a three-level scale (no problems, some problems or a lot of problems) along with a visual analogue scale (VAS) from 0 (worst imaginable health) to 100 (best imaginable health). The EQ-5D-Y-3L value sets will be used to calculate utility values.

Time frame: Through study completion, an average of 6 months

Group 1 respondents' assessment of Bolt-on vision

Group 1 respondents are parents (or other proxy) of children and adolescents suffering from myopia. The vision bolt-on assessment is an extension to the EQ-5D tool to specifically address the impact of vision impairment on a person's quality of life and consists of a single question in the same format.

Time frame: Through study completion, an average of 6 months

Group 1 respondents' assessment of PedEyeQ (Pediatric Eye Questionnaire)

Group 1 respondents are parents (or other proxy) of children and adolescents suffering from myopia. The PedEyeQ (Pediatric Eye Questionnaire) proxy version is a HRQoL (Health Related Quality of Life) assessment tool specifically designed to measure the impact of pediatric eye conditions on children. The tool consists of age-appropriate questionnaires (5-11 years old and 12-17 years old) that assess how vision problems affect daily activities, social interactions, school performance, and overall well-being of the child.

Time frame: Through study completion, an average of 6 months

Group 2 respondents' assessment of EQ-5D-5L

Group 2 respondents are adult patients suffering from myopia and a long-term complication of myopia. The EQ-5D-5L (European Quality of Life 5 Dimensions 3 Level) includes five questions covering mobility, self-care, usual activities, pain/discomfort and anxiety/depression. This questionnaire will be administered to adults suffering from myopia plus a complication. Each domain is rated from 1 (best quality) to 5 (worst quality), along with a VAS from 0 (worst imaginable health) to 100 (best imaginable health).

Time frame: Through study completion, an average of 6 months

Group 2 respondents' assessment of Bolt-on vision

Group 2 respondents are adult patients suffering from myopia and a long-term complication of myopia. The vision bolt-on is an extension to the EQ-5D tool to specifically address the impact of vision impairment on a person's quality of life. The EQ-5D-5L value sets will be used to calculate utility values for adults with myopia and its complications.

Time frame: Through study completion, an average of 6 months

Group 2 respondents' assessment of NEI-VFQ-25 (National Eye Institute Visual Function Questionnaire-25)

Group 2 respondents are adult patients suffering from myopia and a long-term complication of myopia. The NEI-VFQ-25 (National Eye Institute Visual Function Questionnaire-25) is a tool used to assess VRQoL (Vision Related Quality of Life) in individuals aged 18 and older. It consists of 25 items that measure the impact of vision impairment on daily activities and well-being across 12 domains, including visual function, mental health, social functioning, and role limitations. The NEI-VFQ-25 helps evaluate how visual problems affect a person's ability to perform tasks like reading, driving, and interacting socially.
