Photolithography Microstructure Myopia Management Lenses in Preventing and Controlling Myopia in Children and Adolescents

A Randomized Controlled Clinical Study Evaluating the Effectiveness, Safety, and Comfort of Photolithography Microstructure Lenses for Managing Myopia in Children and Adolescents

Evaluate the effectiveness of different lithographic microstructured myopia management lenses in controlling the progression of myopia in children and adolescents, as well as the safety and comfort of wearing them. Explore effective defocus microlens designs for myopia control and the feasibility of applying lithographic microstructured myopia management lenses in myopia prevention and control.

Inclusion Criteria:

• Age: 6 to 14 years old.
• After administering 1% Cyclopentolate Hydrochloride Eye Drops (Saifeijie) to induce ciliary muscle paralysis, both eyes showed refractive errors between -0.50D and -4.00D, with binocular lens differences ≤ 1.50D and anisometropia ≤ 1.50D. Best corrected visual acuity was 5.0 or better.
• Have not used over-focus glasses, corneal reshaping lenses, defocus flexible glasses, progressive lenses, atropine eye drops, red light therapy, acupuncture, moxibustion, or other myopia prevention methods within the past three months.
• The subject is willing to receive treatment, and their legal guardian has signed an informed consent form.

Exclusion Criteria:

• Diagnosed with persistent strabismus.
• Diagnosed with pathological myopia.
• Other congenital eye diseases.
• Other reasons the research doctor deems unsuitable for inclusion in the project.
