This study compared refractive and axial length (AL) changes in children wearing dual-focus soft contact lenses for myopia control (MiSight®) with myopic children wearing spectacles one year from the start of lockdown during the COVID-19 pandemic.
This retrospective, descriptive, parallel-group, observational study reviewed the charts of 11 children who began treatment for myopia control with dual-focus soft contact lenses for myopia control (MiSight®) in March 2020 and 11 matched spectacle-wearing controls. The mean increase in spherical equivalent refraction (SER) and AL from the beginning of the lockdown and up to 1 year later were compared. The parents of the children were asked about the average time spent on near work, contact lens wearing time both during and after the strict confinement and whether they had discontinued contact lens wear during lockdown.
During this first year of preventive COVID-19 measures (March 2020-March 2021), for the contact lens group the average SER and AL increased -0.14 ± 0.09D and 0.13 ± 0.05 mm, respectively. For the spectacle wearers, the corresponding increases were -0.54 ± 0.16D and 0.25 ± 0.08 mm, respectively. A significant difference was found between the groups for both SER (p < 0.001) and AL (p < 0.05). The average time spent outdoors was restricted for both groups during lockdown and increased after. However, statistically significant changes in the time spent outdoors during and after lockdown were only found for the spectacle group (p < 0.05; t-test), whereas this change was not significant for the contact lens group (p = 0.08).
Over the observed time period, dual-focus soft contact lenses for myopia control were effective despite the decreased time spent outdoors during the COVID-19 pandemic.
本研究比较了在 COVID-19 大流行期间，近视控制多焦点软镜（MiSight®）使用者和戴镜者在封锁开始一年后的屈光度和眼轴（AL）变化。
本回顾性、描述性、平行组、观察性研究回顾了 2020 年 3 月开始接受近视控制多焦点软镜（MiSight®）治疗的 11 名儿童和 11 名匹配的戴镜对照组儿童的图表。比较了从封锁开始到 1 年后，等效球镜（SER）和 AL 的平均增加量。询问了儿童家长在近距工作上的平均用时、戴镜时间（包括严格隔离期间和隔离解除后），以及他们在封锁期间是否停止戴镜。
在这一预防性 COVID-19 措施的第一年（2020 年 3 月至 2021 年 3 月），对于接触镜组，SER 和 AL 的平均增加量分别为-0.14±0.09D 和 0.13±0.05mm。对于戴镜者，相应的增加量分别为-0.54±0.16D 和 0.25±0.08mm。两组之间在 SER（p<0.001）和 AL（p<0.05）方面均存在显著差异。两组在封锁期间和之后的户外活动时间均受到限制，但仅在戴镜组中发现封锁期间和之后户外活动时间的变化具有统计学意义（p<0.05；t 检验），而接触镜组的变化不具有统计学意义（p=0.08）。
在观察期间，尽管 COVID-19 大流行期间户外活动时间减少，近视控制多焦点软镜仍有效。
