Myopia-control Efficacy by Peripheral Defocus Lens (PDL)
NCT05373693 · Status: UNKNOWN · Phase: NA · Type: INTERVENTIONAL · Enrollment: 160
Last updated 2022-05-13
Summary
The proposed study below aims to assess the effect of customized Bestivue PDL lenses on retinal image quality and myopia control. A total of 160 subjected would be enrolled in and randomized to allcoate into four groups. Visual acuity and image blur at various gaze directions and eccentricities on children fitted with +2 to 4 D power and single vision lenses would be measured to assess the short term effect of PDL lens. Axial length and cycloplegic objective refractive error would be measured to assess the Myopia-control Efficacy.
