A Prospective Randomized Controlled Trial on the Effect of Light-Blocking Lenses on Emmetropization in Hyperopic Anisometropic Children

• Status: Not Yet Recruiting
• Phase: N/A
• Study type: Interventional
• Enrollment: 90 (estimated)
• Sponsor: Zhongshan Ophthalmic Center, Sun Yat-sen University · Academic / Other
• Sex: All
• Age: 6 Years – 12 Years
• Healthy volunteers: Not accepted

Summary

To evaluate the effectiveness of light-blocking lenses in promoting emmetropization and reducing anisometropia in children with hyperopic anisometropia, and to assess the impact of light-intercepting lenses on visual function in this population.

Conditions

• Anisometropia
• Hyperopia

Interventions

Type	Name	Description
OTHER	light-blocking lenses	The eye with higher hyperopia will be fitted with light-blocking lenses for full-time wear, while the fellow eye with lower hyperopia will be fitted with conventional single-vision lenses for full-time wear, over 12 months
OTHER	single-vision lenses	Both eyes of the subjects will be fitted with conventional single-vision lenses for full-time wear over 12 months.
