Resumen:
Purpose
To evaluate the perception of light disturbances (LD) in children wearing Dual Focus (DF) MiSight® contact lenses (CLs) for myopia control compared with children wearing single vision spectacles (SV).
Methods
This was a randomized, controlled clinical trial involving subjects aged 8–12 with myopia of -0.75 to -4.00D and astigmatism <1.00D allocated to MiSight® study CLs group or control group wearing SV. LD was determined at baseline, 12 and 24 months visit with a validated device, Light Disturbance Analyzer (LDA) to determine the shape, size and regularity of the LD phenomena with parameters of Light Disturbance Index (LDI) Best Fit Circle (BFC) and Standard Deviation between LD and BFC (BFCIrreg.SD).
Results
74 children completed the study, 41 in the CL group and 33 in the SV group. SV group didn´t show any significant differences between monocular and binocular LD measurements throughout the study. Binocular BFCRadius was smaller at 24 months visit compared with 12 month visit (p < 0.05) and for BFCIrreg.SD was significantly smaller at 24 month visit compared with baseline (p < 0.05). In MiSight® group, binocular and monocular LDI, BFCRadius and BFCIrreg.SD measurements didn’t...
