Spectacles slow myopic progression

Hong Kong scientists have reported promising results from a two-year randomised clinical trial involving 183 children in British Journal of Ophthalmology

Daily wear of customised spectacle lenses slowed myopic progression and axial elongation in a two-year randomised clinical trial involving 183 Chinese children.

Children in the study group were between the ages of eight and 13 with myopia between -1.00 and -5.00 dioptres and had astigmatism of 1.5D or less.

Writing in British Journal of Ophthalmology, scientists highlighted that myopia progressed 52% slower in children wearing Defocus Incorporated Multiple Segments (DIMS) lenses when compared to progression in children wearing single vision lenses.  

“Our results demonstrated simultaneous clear vision with constant myopic defocus can slow myopia progression,” the authors highlighted.

Children assigned DIMS spectacles had 62% less axial elongation when compared to the single vision group.

Around one in five (21.5%) children in the DIMS group had no myopic progression over the two-year period, compared to 7.4% of those in the single vision group.

The authors emphasised that the DIMS lenses show potential as an alternative treatment modality for myopia control.

“This intervention is simple to use and is the least invasive method compared with pharmacological or contact lens treatments,” they highlighted.
