We evaluated the impact of an automatic refill program on patterns of medication use. STUDY DESIGN Retrospective propensity score matched cohort study with(More)
Accommodative amplitude (AA; the difference, measured in diopters, between the near and far points of vision) declines steadily with age such that, by midlife, most individuals are unable to focus clearly on near objects and, thus, are said to be presbyopic. Conversely, intrinsic lens fluorescence (LF) increases steadily with age. Previous studies have(More)
