Presbyopia, a loss of accommodative ability associated with aging, is a significant cause of vision impairment globally. At the clinical level, it is a frustrating and difficult issue that negatively impacts patients' quality of life. Less appreciated is the fact that loss of accommodative ability and its current treatments methods may present safety concerns, for example, increasing the risk of falls. Therefore, a more complete understanding of treatment options with respect to how they relate to the natural ability of the eye is needed to improve decision making and to aid clinicians in individualizing treatment options. This article reviews the options for expanding functional through focus-a term coined to describe the ability of the eye to see at all distances with minimal latency-by how they vary the refractive power over time, across the visual field, between eyes, or across a range of distances.
老花眼是一种与衰老相关的调节能力丧失，是全球视力障碍的一个重要原因。在临床层面，这是一个令人沮丧且棘手的问题，会对患者的生活质量产生负面影响。鲜为人知的是，调节能力丧失及其当前的治疗方法可能存在安全隐患，例如，会增加跌倒风险。因此，需要更全面地了解治疗方案及其与眼睛自然能力的关系，以改善决策并帮助临床医生个性化定制治疗方案。本文通过聚焦功能扩展的选项进行综述——聚焦功能扩展是一个新造术语，用于描述眼睛以最小延迟看清所有距离物体的能力——根据它们如何随时间、在视野范围内、双眼之间或一系列距离上改变屈光力来进行综述。
