BACKGROUND An understanding of physiologic age-related shifts in myopic refractive errors is important to the refractive surgeon for the interpretation of long-term results, surgical planning, and patient counseling. This study characterizes the refractive stability of adult simple myopia with a retrospective study of 413 eyes. METHODS Approximately 74,000 patient records were analyzed to ide...

INTRODUCTION Spectacle non-compliance is a significant problem in pediatric patients, and may have a variety of consequences. Non-compliance with myopic refractive correction could be secondary to a variety of issues, including age, discomfort, gender, urban vs. rural residence, presenting visual acuity, and degree of refractive error. We observed a phenomenon in our pediatric patients with ret...

A 19-year-old girl presented with advanced unilateral chronic angle closure glaucoma and myopia with gross cupping and field loss in a previously hyperopic eye with a marked increase in corneal curvature. This emphasises that a marked myopic shift may be an important sign of glaucoma in a young patient.

PURPOSE Negative-lens-induced defocus causes accelerated ocular elongation and myopia, whereas positive-lens-induced defocus produces reduced ocular elongation and hyperopia. Short durations of positive lens wear result in markedly stronger temporal effects than do short periods of negative lens wear in the chick model of refractive development. In mammalian and nonhuman primate models, there h...

BACKGROUD Postlaser in situ keratomileusis (post-LASIK) refractive regression is defined as the gradual, partial, or total loss of initial correction that limits the predictability, efficiency, and long-term stability of LASIK. Our study assesses the effect of Timolol 0.5% on the correction of myopic regression after LASIK. METHODS This prospective, randomized, controlled study included 62 ey...

INTRODUCTION Myopia is the most common eye disorder especially in Asia. However, the information on myopic progression and ocular growth among preschool children, who undergo rapid changes, is limited. The aim of this study was to determine the prevalence, incidence of myopia and myopic progression among preschool children in Hong Kong. MATERIALS AND METHODS A kindergarten was randomly chosen...
