Clinical Trial Summary

Phase IV clinical trial to evaluate whether there is a significant difference in the control of myopia progression in myopic children treated with 0.025% atropine and DIMS spectacle lenses compared to 0.025% atropine and single vision (SV) lenses. Open-label, randomized, parallel clinical trial involving 50 subjects in each treatment arm (100 patients in total). The primary efficacy endpoint will be the change in cycloplegic spherical equivalent refraction (SER) and axial length (AL) compared to baseline values.

• Amblyopia
• Previous eye surgery
• Systemic pathology (cardiopulmonary pathology, connective tissue alterations, neurological or psychiatric pathology) or baseline situation of the patient that does not allow the examination to be carried out (such as mental or psychomotor retardation)

Intervention

Drug:
• Atropine 0,025%
Atropine 0,025% (1 drop per day)

Device:
• DIMS Lenses
Use of peripheral defocus lenses with DIMS technology, the design of which simultaneously introduces myopic defocus and provides clear vision to the wearer at all viewing distances.
• Monofocal lenses
Use of monofocal lenses.
