is the loss of lens accommodation with age that results in an inability to focus at near distances. It is receiving growing attention because of the recognition that good near vision is needed to accomplish a broad range of tasks, not only reading and writing. Research shows that there are differences between men and women in the prevalence, age of onset, and severity of presbyopia, 1 in the ty...

PURPOSE To characterize refractive error, presbyopia, and spectacle correction among adults aged ≥40 years in Timor-Leste in 2010 and examine the impact of the National Spectacle Program by comparing results to those obtained 5 years earlier. METHODS A population-based, cross-sectional survey sampled 50 clusters of 45 people each. Participants with uncorrected and undercorrected refractive er...

Presbyopia, the gradual loss of accommodation that becomes clinically significant during the fifth decade of life, is a physiologic inevitability. Different technologies are being pursued to achieve surgical correction of this disability; however, a number of limitations have prevented widespread acceptance of surgical presbyopia correction, such as optical and visual distortion, induced cornea...

Presbyopia, from the Greek for aging eye, is, like death and taxes, inevitable. Presbyopia causes near vision to degrade with age, affecting virtually everyone over the age of 50. Presbyopia has multiple negative effects on the quality of vision and the quality of life, due to limitations on daily activities - in particular, reading. In addition presbyopia results in reduced near visual acuity,...

Presbyopia is the gradual inability to focus near objects with age. This study explores patients’ attitudes and beliefs towards presbyopia including preferred modes of refractive correction. In United Kingdom, twenty-four volunteers completed an online questionnaire attended a structured, recorded group. Participants’ age ranged between 36 48 years, representing pre-presbyopic presbyopic popula...

RESULTS. Studies of presbyopia including sex as a contributing factor were highly heterogenic (P 1⁄4 0.01) but overall found female sex to be statistically significant in predicting earlier onset for presbyopia with an adjusted confidence interval (CI) using the Shore method of 95% CI [1.02, 1.45]. When limited to studies only measuring accommodative amplitude, female sex was not associated wit...
