PURPOSE To determine the intertester agreement of refractive error measurements between lay and nurse screeners using the Retinomax Autorefractor and the SureSight Vision Screener. METHODS Trained lay and nurse screeners measured refractive error in 1452 preschoolers (3 to 5 years old) using the Retinomax and the SureSight in a random order for screeners and instruments. Intertester agreement...

PURPOSE To describe the prevalence and the risk factors of undercorrected refractive error in an adult urban Malay population. METHODS This population-based, cross-sectional study was conducted in Singapore in 3280 Malay adults, aged 40 to 80 years. All individuals were examined at a centralized clinic and underwent standardized interviews and assessment of refractive errors and presenting an...

PURPOSE Studies in relatives have generally yielded high heritability estimates for refractive error: twins 75-90%, families 15-70%. However, because related individuals often share a common environment, these estimates are inflated (via misallocation of unique/common environment variance). We calculated a lower-bound heritability estimate for refractive error free from such bias. METHODS Bet...

Purpose. The purpose of this study ws~s to evaluate We changes of the refractive error in the follow up after penetrating keratoplasty for Fuchs’ dystrophy. Methods. Between 1960 and 1991 16.2 keratoplasties with mechanical trephination and single running suture ware performed for Fuchs’ dystrophy consecutively. The suture was removed 20,4 f 7.5 months postoperatively. In 99 eyes a simultaneous...

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 evaluate refractive state in children with unilateral congenital nasolacrimal duct obstruction (NLDO). METHODS This descriptive cross-sectional study includes consecutive children with unilateral congenital NLDO. Examination under anesthesia was performed to perform cycloplegic refraction and was followed by appropriate intervention in each patient. Refractive errors of the involve...

Keratoconus provides a decrease of quality of life to the patients who suffer from it. The treatment used as well as the method to correct the refractive error of these patients may influence on the impact of the disease on their quality of life. The purpose of this review is to describe the evidence about the conservative surgical treatment for keratoconus aiming to therapeutic and refractive ...

PURPOSE The purpose of this study was to provide clinical outcomes data related to secondary intraocular lens (IOL) implantation for the correction of residual refractive error after cataract surgery. PATIENTS AND METHODS A chart review was conducted to identify all eyes implanted with the monofocal spherical or toric AddOn® secondary IOL. Data were collated from charts where uncomplicated in...
