Evaluation of the Effectiveness of a New Generation of Myopia Control Lens on the Progression of Myopia in Children Aged 6 to 14 Years

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.
