Orthokeratology is designed to achieve slight over-correction so the optical treatment will last all day. How much overcorrection is ideal to achieve good vision throughout the day while achieving good visual performance?
There’s a common clinical belief that orthokeratology doesn’t work as well in lower myopes for myopia control. This is even sometimes included in conference presentations as prescribing advice. Is orthokeratology useful for control of low myopia? Here’s what’s fact and what’s fiction, when considering its efficacy for low vs high myopia, and orthokeratology vs multifocal contact lens myopia control.
This retrospective cohort study established the prevalence of adverse events in children wearing soft contact lenses, and found them comparable to established rates among adults wearing soft CLs.
对于许多使用数字设备的孩子来说，这是他们日常生活的正常部分，他们将在学校和家里使用计算机和手持设备。这项系统的审查整理了这项已发表的研究，以阐明对儿童在数字设备上花费的时间与近视的发病率，流行或进展的时间之间的关联。

Children are accessing screens at school, around the home and for personal entertainment at younger and younger ages. At the same time, there has been an unprecedented increase in myopia in children, with higher numbers and earlier age of onset. Read about what we do and don’t know about this link; the impact of screen time on binocular vision and dry eye in kids, and guidelines for advice to parents.
专注于阅读和学习等特写任务的视觉需求被认为是增加儿童近视的推动力。为了更好地理解这种关系，作者合并了几项研究的数据，以量化近乎工作活动对儿童近视的影响，并发现他们之间可能存在任何关联。
Childhood refractive error is dictated by several factors including parental myopia and how much time they may spend outdoors each day. Influenced by these factors the shape and size of the eye constantly changes during growth with axial length most influenced as myopia increases. This longitudinal study sought to model these changes in Chinese children.
Pre-myopes can be readily identified, and best practice dictates that we should offer some form of intervention to help delay the onset of myopia. In this case we discuss the features of a pre-myope and an example in a 5 year old patient who satisfies the refractive criteria for pre-myopia, and has a strong family history of myopia.
