introduction: today, lasik surgery is one of the most common and effective procedures for correction of refractive errors. less than 1% of patients undergoing lasik operation suffer from serious and 3-5% suffers from mild complications. also, results of lasik in most centers are promising. with the recent inauguration of the lasik center of yazd, it was decided to evaluate the results and compl...

BACKGROUND Identifying and assessing retinal nerve fiber layer defects are important for diagnosing and managing glaucoma. We aimed to investigate the effect of refractive correction error on retinal nerve fiber layer (RNFL) thickness measured with Spectralis spectral-domain optical coherence tomography (SD-OCT). MATERIAL AND METHODS We included 68 participants: 32 healthy (normal) and 36 glauc...

OBJECTIVE To estimate the psychometric properties of a vision-targeted measure of health-related quality of life, the National Eye Institute-Refractive Error Quality of Life survey (NEI-RQL), which includes 13 scales designed to assess the impact of refractive error and its correction on day-to-day life. DESIGN Cross-sectional survey. PARTICIPANTS The NEI-RQL was self-administered by 667 my...

PURPOSE To identify risk factors for inadequately corrected refractive error in the United States. METHODS This cross-sectional study included 12,758 participants 12 years of age and older from the 2005 to 2008 National Health and Nutrition Examination Survey. The primary outcome was the proportion of individuals with inadequate refractive correction for whom refractive correction would resul...

PURPOSE The purpose of this study was to evaluate the refractive and visual outcomes of wavefront-guided laser in situ keratomileusis (LASIK) in eyes with myopic astigmatism and cylindrical component ≥2.0 diopter (D). METHODS In this retrospective study, 611 eyes that underwent LASIK for simple or compound myopic astigmatism were analyzed. Preoperative refractive cylinder ranged from -2.00 D ...

OBJECTIVES To evaluate the effect of vision-enhancing interventions (cataract surgery or refractive error correction) on physical function and cognitive status in nursing home residents. DESIGN Longitudinal cohort study. SETTING Seventeen nursing homes in Birmingham, Alabama. PARTICIPANTS A total of 187 English-speaking adults aged 55 and older. INTERVENTION Participants took part in on...

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...

OBJECTIVE To examine the effect of treating uncorrected refractive error through spectacle correction on vision-targeted health-related quality of life and depressive symptoms in nursing home residents. METHODS Persons aged 55 years or older residing in nursing homes in Birmingham, Alabama, having uncorrected refractive error were randomly assigned to either immediate spectacle correction of ...

purpose: to report a case who had undergone lasik in his right eye and prk in the fellow eye for correction of equivalent myopia but developed progressive post-operative keratectasia only in the right eye. patient and findings: a 30-year-old man had undergone lasik in right eye 3 years ago for correction of refractive error of -1.75  -1.50@48° and prk in left eye 2 years ago for correction of r...
