Evaluation of the Effectiveness of a New Generation of Myopia Control Lens on the Progression of Myopia in Children Aged 6 to 14 Years
brief summary
The goal of this clinical investigation is to learn how much a new generation of myopia control lens (MCL1 - Myopia Control Lens 1) is helpful in reducing myopia progression in children from 6 to 14 yo. The main questions it aims to answer is: How much this new generation of lens, called MCL1, slows down the growth of the eye? Researchers will compare MCL1 to a former generation of myopia control lens (i.e. MCL2) but with better vision quality. Participants will: * Wear MCL1 on right eye and MCL2 on left eye for 6 months and MCL2 on rigth eye and MCL1 on left eye for the next 6 months; * Visit the hospital at 6 and 12 months for tests; * Answer weekly questionnaires on compliance wearing glasses, quality of vision and out-of-school activities.
detailed description
Myopia is a global public health issue that could affect nearly 5 billion people by 2050. It progresses rapidly in children, increasing the risk of severe ocular diseases. Several solutions exist to slow its progression, including ophthalmic lenses, which are effective and free of side effects. Essilor® Stellest® lenses, incorporating H.A.L.T. technology with aspherical lenslets, slow axial eye elongation with an efficacy comparable to high-dose atropine.
A new version of this product provides an enhanced myopia-control signal thanks to increased optical parameters of the lenslets. A recent study has demonstrated its superior effectiveness in Asian children aged 6 to 10. The present study aims to assess its performance in European children, compared with another myopia control lens, which delivers the same myopia-control signal as the original Stellest® lens but with better visual quality.
The study will take into account interindividual variability in efficacy, particularly with respect to age-a key factor in myopia progression (which is high between ages 6 and 8). Three age groups will be analyzed (6-8, 9-11, and 12-14 years). A secondary objective is to explore the impact of individual ocular parameters on lens effectiveness.
