Wearability of and Myopia Progression With ZEISS MyoCare Spectacle Lenses
Trial Parameters
Brief Summary
This is a clinical trial evaluating the wearability and effectiveness of three types of ZEISS spectacle lenses in controlling myopia progression. This study compares ZEISS MyoCare spectacle lenses with two types of single-vision spectacle lenses over a 6-month period. This trial aims to evaluate how well these lenses are worn and their impact on myopia progression, including changes in axial length and refractive error. Participants will be randomly assigned to wear one of three types of ZEISS spectacle lenses. The study will require five visits to the eye clinic over a 6-month period and two virtual follow-up visits.
