Long-term DIMS lens users report high satisfaction despite cost barrier
Young adults who previously wore defocus incorporated multiple segments (DIMS) spectacle lenses reported high long-term satisfaction and confidence in their effectiveness for slowing myopia progression, but the cost of the lenses was a major barrier to continued use, according to a study.
The retrospective mixed-methods study included 63 former child participants, now aged 17 to 23 years, who had taken part in a DIMS clinical trial 8 to 10 years earlier. Two years after the trial ended, participants completed an online questionnaire and in-depth phone interviews about their experiences.
Lens durability and ease of maintenance were the strongest drivers of long-term satisfaction, alongside favorable perceptions of appearance.
According to the interviews, most participants’ DIMS spectacle use began at the direction of their parents and involved a manageable period of sensory adaptation. Participants also reported strong perceptions of efficacy based on their personal experiences.
Despite the positive experience, only one-third of participants continued using DIMS lenses. The decision to discontinue use was overwhelmingly attributed to the high cost of the spectacles.
