Targeted Lens Intervention for Myopic Anisometropia in Children
Starting soon · Not applicable
Conditions studied: Anisometropia, Myopia
In brief
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
