> **NCT06148519** · NA · TERMINATED · sponsor: **Department of Medical Services Ministry of Public Health of Thailand** · enrollment: 250 (actual)

## Conditions studied

- 2WIN-S Portable Refractor

## Interventions

- **DIAGNOSTIC_TEST:** 2WIN-S portable refractor

## Key facts

- **NCT ID:** NCT06148519
- **Lead sponsor:** Department of Medical Services Ministry of Public Health of Thailand
- **Sponsor class:** OTHER_GOV
- **Phase:** NA
- **Study type:** INTERVENTIONAL
- **Status:** TERMINATED

- **Primary completion:** 2024-04-30
- **Final completion:** 2024-04-30
- **Target enrollment:** 250 (ACTUAL)
- **Why stopped:** Because the research team plans to change the protocol, we do not plan to conduct cycloplegic refraction, which requires dilation. Instead, we will use only 2-WINS for eye and vision screening. Additionally, we will change the study site
