From the Research
The diagnostic workup for Defocus Incorporated Multiple Segments (DIMS) should include a comprehensive assessment of myopia progression, including cycloplegic autorefraction and axial length measurements, as evidenced by a 2-year randomised clinical trial 1. The workup for DIMS, in the context of myopia control, should focus on the use of DIMS spectacle lenses, which have been shown to slow myopia progression by 52% compared to single vision lenses 1. Key components of the workup include:
- Cycloplegic autorefraction to measure refractive error
- Axial length measurements to assess eye growth
- Regular follow-up appointments to monitor myopia progression
- Consideration of other factors that may influence myopia progression, such as near work and outdoor activity levels It is essential to note that the term DIMS can refer to different concepts, and in the context of myopia control, it specifically refers to Defocus Incorporated Multiple Segments spectacle lenses. The most recent and highest quality study on this topic is the 2-year randomised clinical trial published in 2020 1, which provides strong evidence for the effectiveness of DIMS lenses in slowing myopia progression. In contrast, other studies with the reference_id 2,3,4, and 5 do not provide relevant information for the diagnostic workup of DIMS in the context of myopia control. Therefore, the diagnostic workup for DIMS should prioritize the use of DIMS spectacle lenses and regular monitoring of myopia progression, as supported by the highest quality evidence available 1.
