original article   to determine the association between ocular biometric components and near work in bank employees.this study was conducted as an analytical cross-sectional study. a group of bank employees and a control group were randomly selected. after applying the inclusion criteria, all selected subjects had a set of examinations including refraction, uncorrected and corrected visual acui...

purpose: to determine the distribution of axial length (al), vitreous chamber depth (vcd), anterior chamber depth (acd), lens thickness (lt), lens power (lp), radius of curvature (cr), and white-to-white corneal diameter (wtw) in the 14-20 year age range methods: in a cross-sectional study, sampling was done from aligoodarz high schools using multistage simple cluster sampling. for all students...

purpose : to determine the relationship between refractive errors and ocular components values in carpet weavers methods : refractive errors and ocular components values were investigated on carpet weavers at mashhad city in iran . after selection of samples, the individuals who had ophthalmic and systemic disease effective on the refractive errors were excluded from the study. refractive error...

PURPOSE The study compared ocular biometry values using applanation and immersion techniques to determine the most applicable method for our tertiary training centre where personnel with different levels of experience and expertise in biometry take measurements used in calculation of required intraocular lens before cataract surgery. METHODS The study was a prospective cross-sectional compara...

OBJECTIVES To compare the anterior ocular segment biometry among Type 2 diabetes mellitus (DM) with no diabetic retinopathy (DR) and non-proliferative diabetic retinopathy (NPDR), and to evaluate the correlation of anterior ocular segment biometry with HbA1c level. METHODS A cross-sectional study was conducted in Hospital Universiti Sains Malaysia, Kelantan from November 2013 till May 2016 am...

PURPOSE To examine ocular growth in nonhuman primates (NHPs) from measurements on ex vivo eyes. METHODS We obtained NHP eyes from animals that had been killed as part of other studies or because of health-related issues. Digital calipers were used to measure the horizontal, vertical, and anteroposterior globe diameters as well as corneal horizontal and vertical diameters of excised globes fro...

PURPOSE To compare the repeatability and reproducibility of ocular biometry and intraocular lens (IOL) power obtained with a new optical biometer (AL-Scan) and a standard optical biometer (IOLMaster 500). SETTING Siriraj Hospital, Mahidol University, Bangkok, Thailand. DESIGN Prospective comparative study. METHODS Two independent operators measured eyes with cataract using both biometers....
