Targeted Lens Intervention for Myopic Anisometropia in Children

Condition(s) studied

Investigational drug(s) / intervention(s)

More myopic eye: MCL1; Less myopic eye: MCL2: Each participant wears the study eyeglasses containing both Myopia Control Lens 1 (MCL1) and Myopia Control Lens 2 (MCL2) design, with one type of lens in each eye throughout the study period. MCL1 will be worn in the more myopic eye, and MCL2 in the less myopic eye for a period of 12 months.

Study summary

The goal of this clinical trial is to learn if our research spectacles will lower the difference in prescription (spectacles degree) between the eyes in children between 6 to 13 years old with anisometropic myopia. Anisometropic myopia is when the difference in myopia prescription between the two eyes are more than 1 diopter. The main question it aims to answer is:

* How the eye responds to the research spectacles over time by measuring:

1. Change in axial length: the physical length of the eye from front to back.
2. Change in cycloplegic spherical equivalent refraction: an accurate measurement of the eye's prescription taken while the focusing muscles are temporarily relaxed with eye drops.

Participants will:
* Wear the study spectacles
* Visit Essilor R\&D Centre and an eye clinic for follow-up sessions

Eligibility
