Abstract:

Purpose To compare a biometer using swept-source optical coherence tomography (SS-OCT) with a partial coherence interferometry (PCI)-based biometer in measurements of two ocular biometry parameters, i.e., the axial length and anterior cornea curvature. Methods We compared the two biometers SS-OCT (ANTERION, Heidelberg Engineering Inc., Heidelberg, Germany) and PCI (IOL Master, Carl Zeiss Meditec, Jena, Germany) in terms of the axial length (AL) and corneal curvature (K) measurements of 175 eyes. Paired t-tests were used to compare the two biometers. Agreement between the biometers was evaluate

Forty-two eyes of 42 keratoconus (KC) patients enrolled in the study were examined. Clinical and demographic characteristics of the patients were noted, and detailed ophthalmological examination was performed. Following Pentacam measurements, central corneal thickness (CCT), anterior chamber depth (ACD), lens thickness (LT), and axial length (AL) were obtained using the Lenstar and US biometer to determine the reproducibility of the measurements between the two devices

Abstract:

Biometry is a critical aspect of ophthalmology, since it facilitates the measurement of several ocular parameters and aids in the diagnosis of conditions like glaucoma. The advent of the IOLMaster in 1999 marked a pivotal moment in biometry by introducing non-contact and highly precise measurements that revolutionized the field. Low-coherence optical reflectometry devices such as Lenstar LS900 and Aladdin have further advanced biometry, due to the exceptional accuracy they offer. Axial length, a fundamental measurement in biometry, directly correlates with conditions like myopia and glaucoma.

Abstract This study sought to compare the biometric values and intraocular lens (IOL) power obtained by standard ultrasound and optical biometry. We examined 29 eyes in preparation for cataract surgery. None of the patients had refractive surgery or corneal anomaly. In all patients, the horizontal and vertical refractive power of the cornea was determined using a keratometer (Bausch&Lomb). The axial length of the eye was determined via A-scan ultrasound (BVI-compact-V-plus) using Hollady’s formula. The IOL power and complete biometric measurements were obtained via an IOL Master-500-Zeiss

Methodology: Prospective and Interventional Randomized Comparative Study, Sample size of 400, studied under two sub groups, for Axial Length readings and IOL power calculation by A-Scan (Biomedix) and AL-Scan (Nidek). Keratometry readings are taken only by AL-Scan.Results: Mean ± St. dev. of A.L. measured by App. Biometry was low (22.79 ± 0.9 mm) than Opt. Coh. Biometry (23.16 ± 0.78 mm) to be significant (P= .

Abstract:

High-precision biometry and accurate intraocular lens (IOL) power calculation have become essential components of cataract surgery. In clinical practice, IOL power calculation involves measuring parameters such as corneal power and axial length and then applying a power calculation formula. The importance of posterior corneal curvature in determining the true power of the cornea is increasingly being recognized, and newer investigative modalities that can estimate both the anterior and posterior corneal power are becoming the standard of care. Optical biometry, especially using swept-source bi

Abstract:

A conformação do úbere dos caprinos possui relevância, uma vez que seu tamanho e forma estão associados à capacidade de produção de leite. Neste sentido, o objetivo do presente estudo foi determinar a relação entre as medidas da glândula mamária e a produção de leite em cabras da raça Anglonubiana. Em 15 cabras em lactação foram determinadas as medidas: circunferência e profundidade de úbere; a circunferência e comprimento de teto. As medidas foram realizadas antes (úbere cheio) e após a ordenha (úbere vazio). Ao final da ordenha matutina foi mensurada a produção de leite (em g). A produção de

Abstract:

To compare the refractive outcomes after phacoemulsification with an Intra ocular lens (IOL) using IOL master 700 optical biometer versus conventional ultrasonographic biometer. A retrospective analysis of patients who underwent phacoemulsification with intra ocular lens implantation between April 2019 and March 2020 was done. Data of 654 eyes (607 patients) was shortlisted and analyzed. IOL power calculation was done with applanation ultrasonographic biometer and IOL Master 700 optical biometer by dividing patients into 2 groups. SRK/T formula was used in both cases for IOL power calculation.

Abstract:

Background: Aim of this study was to analyse the ocular biometric parameters and their associations in a population of cataract surgery candidates.Methods: Ocular biometry records were retrospectively analyzed for 84634 patients with cataracts (84634 eyes) who were treated at Northern Indian region. Ocular biometry characteristics such as Axial length (AL), the Keratometry readings (K1 and K2), and Posterior chamber intraocular lens (PCIOL) power of patients were assessed to find mean, standard deviation, minimum value and maximum value. Statistical analysis was done in Statistical package for

Abstract:

When ICAO approved a new standard for international passports, they recommended including a high-resolution facial image on a chip in addition to the visual portrait on the identity page. Accordingly, there is, in a certain sense, two images in the current passport, one on the chip, the other visually displayed. In this article I relate the functional distribution between these two images to the nineteenth-century mugshot and argue that the photographically generated images in the current passport represent a subdued tension between two parallel paths in the history of photography: depiction a
