MiyoSmart Effectiveness Confirmed

Three year results, published in the British Journal of Ophthalmology,1 confirm the MiyoSmart lens with patented Defocus Incorporated Multiple Segments (DIMS) Technology can achieve a “significant and immediate slow-down in the progression of myopia” and the slowing is sustained.

The new study, conducted by the Centre for Myopia Research at The Hong Kong Polytechnic University, follows the two-year study, which demonstrated evidence of the effectiveness of the lens in slowing myopia progression, on average by 60% in children aged eight to 13.

The follow-up study was conducted on 120 children in Asia, included 65 from the original group using the MiyoSmart lens, and 55 who moved from using a single-vision lens for two years to the MiyoSmart lens in the third-year of the study. Final results in the original group of children using MiyoSmart lenses showed slowing in myopia progression over time was sustained and the second group showed a significant and immediate slow-down in myopia progression.

“The results are very positive, providing evidence that the lens continues to slow myopia progression in children, including the impressive results when switching from a single vision lens,” said Griff Altmann, Chief Technology Officer at Hoya Vision Care.

The DIMS spectacle lens design is based on the principle of myopic defocus and simultaneous vision. A dual-focus spectacle lens, it consists of a central optical zone for correcting distance refractive error, and a batch of tiny circular segments with a relative positive power of 3.50D equally distributed throughout the mid-peripheral area in a honeycomb pattern. This imposes myopic defocus while providing clear vision for the wearer, simultaneously at all viewing distances.1
