Abstract
Purpose :
This pilot study aims to investigate the adaptability of DIMS lens in pre-myopic children.
Methods :
This pilot study will enroll children aged 5-6 diagnosed with pre-myopia from 2023 to 2024. Eligible participants should have a cycloplegic refraction ranging from <= +0.75 to > -0.5 diopters. During the baseline visit, participants and their caregivers will be instructed to wear DIMS spectacle lenses full-time. At the one-week visit, participants will be queried about visual complaints, and the acceptability of DIMS lenses will be assessed using an initial questionnaire. Subsequently, compliance with DIMS wearing and information on myopia-related lifestyle habits will be gathered through follow-up questionnaires.
Results :
In total, we enrolled 24 pre-myopic children (Table 1). The mean age was 5.4 ± 0.59 years old, with a male-to-female ratio of 11:13. The visual acuity of all children was 20/20 on the Snellen visual acuity chart. The mean spherical equivalent was +0.25 diopters. The ratio of parental myopia was 16:7:1 for none, one parent, and both parents, respectively. The mean axial length was 22.48 ± 0.63 millimeters.
When using DIMS lenses, near visual acuity was 20/20 on the near chart for all children. After wearing DIMS lenses for one week, the most reported visual complaint was the inconvenience of daily activities at school (16.7%) (Figure 1). In this group of children, the frequency and severity were reported as mild. Other reported visual complaints included visual strain (8.3%), photophobia (8.3%), and the need for lens position adjustment (8.3%). All parents expressed agreement to continue their children wearing DIMS lenses.
Conclusions :
This pilot study indicates that DIMS lenses exhibited high adaptability in preschool-aged pre-myopic children. Visual complaints were minimal and of mild severity. Further studies are currently underway to explore their efficacy in managing myopic progression and alterations in ocular parameters.
