Study Comparing Eye Growth Over Time in Children Using Two Myopia Control Lenses

A Monocentre, Randomized, Contralateral Trial to Study the Effect of Temporal Changes in Ocular Biometry of Two Myopia Control Lenses

The goal of this clinical trial is to investigate the short-term changes in the eye structure while wearing two types of lenslet-based myopia control lenses over a period of 6 months in children aged 6 to 13 years with myopia. The main question it aims to answer is:

• How the eye responds, at each timepoint, to the two myopia control lenses by evaluating:

  1. Change in axial length

  2. Change in choroidal thickness

     Participants will:

• Wear the study spectacles

• Visit Essilor R&D Centre for follow-up sessions

Inclusion Criteria:

• Volunteer participant

• Informed consent of parent or guardian and assent of participant

• Age: Equal to or greater than 6 years but not older than 13 years at the time of informed consent and assent.

• Refractive error (manifest refraction):

  • Equal or less than -0.50 D or equal or greater than -4.75D.
  • Astigmatism should be less than or equal to 2.00D.

• Anisometropia should be less than or equal to 1.00D

• Best corrected visual acuity: Better than 0.2 logMAR in each eye

• Willingness and ability to:

  • participate in trial for at least 6 months.
  • attend scheduled visits.
  • not to be involved in other myopia control treatments concurrently.

• No history of any myopia control interventions (i.e., myopia control spectacle lenses, myopia control contact lenses, orthokeratology lenses or atropine, etc.)

Exclusion Criteria:

• History or presence of:

  • An ocular disease
  • Strabismus
  • Amblyopia

• Currently or previously on any myopia control interventions (i.e., myopia control spectacle lenses, myopia control contact lenses, orthokeratology lenses or atropine, etc.)
