A recently published 2-year study matched for age and gender to a previously conducted 1-year study showed a comparatively significant reduction in the progression of myopia with soft multifocal contact lenses than the 1-year study, as well as a significant reduction in axial elongation.
Subjects in the recent 2-year study were fitted with +2.00 D add (Proclear Multifocal "D,” CooperVision), and subjects of the previous 1-year study were fitted with single-vision contact lenses (1-Day Acuvue, Vistakon).
Children between 8 and 11 years old with -1 D to -6 D spherical component and less than 1 D astigmatism were included in the study.
The study authors observed a spherical equivalent progression of myopia at 2 years of -1.03 D for the single-vision contact lens wearers and -0.51 D for the soft multifocal contact lens wearers (P < .0001). Mean axial elongation was 0.41 and 0.29 for the single-vision and soft multifocal contact lens wearers, respectively (P < .0016).
Soft multifocal contact lens wear resulted in a 50% reduction in the progression of myopia and a 29% reduction in axial elongation during the 2-year treatment period compared to the historical control group.
“Results from this and other investigations indicate a need for a long-term randomized clinical trial to investigate the potential for soft multifocal contact lens myopia control,” the study authors said.
