NCT06553404

Brief Summary

A Prospective, randomized, controlled double masked trial to assess the performance of Myoslow lens in slowing myopia progression in children. The following study measures will be assessed:

  • Demographics and medical history
  • Current spectacles
  • Best Corrected Visual Acuity (BCVA) assessed by Measurement and Summation (M\&S) system
  • Biometry
  • Cover test
  • Stereopsis
  • Ocular Motility
  • Pupil responses
  • Cycloplegic refraction
  • Fundus Examination
  • Vision related quality of life using the questionnaire Pediatric Refractive Error Profile (PREP)2
  • Adverse Events

Device: Single Vision

myoslow

EXPERIMENTAL

The Myoslow spectacle lens is based on the Defocus Incorporated Multiple Segments (DIMS) mechanism of action. This lens provides the same optical image as the Defocusing Incorporated Soft Contact Lens (DISC) without the drawbacks inherent with contact lens fitting.
