Comparison of the corneal curvatures obtained from three different keratometers.
INTRODUCTION Keratometry forms an important component of the biometry for a calculation of the intraocular lens power and selecting a contact lens' parameters. OBJECTIVE To investigate the agreement between three different keratometers commonly used in an ophthalmology clinic. MATERIALS AND METHODS In this prospective study, keratometry was performed using an IOL Master (IM), a manual kerat...

15 صفحه اولComparison of Compaction Control Parameters Obtained by Different Test Methods
Compaction control in the field can be assessed via sand-cone and nuclear gauge tests. In this study, the data obtained from a series of sand cone and nuclear gauge tests are used to establish relationships between several outcomes of these tests. Comprehensive statistical analyses are applied to the data at hand. Next, linear/nonlinear regression analyses and artificial neural networks are use...
متن کاملOn comparison of the Earth orientation parameters obtained from different VLBI networks and observing programs
In this paper, a new geometry index of Very Long Baseline Interferometry (VLBI) observing networks, the volume of network V , is examined as an indicator of the errors in the Earth orientation parameters (EOP) obtained from VLBI observations. It has been shown that both EOP precision and accuracy can be well described by the power law σ = aV c in a wide range of the network size from domestic t...
متن کاملComparison of the Obtained Results from Two Calibration Methods in MRI Brachytherapy Normoxic Polymer Gel Dosimetry
Introduction: Despite the fact that the clinical implementation of polymer gel dosimetry has been facilitated after the introduction of normoxic gels, there are still complications in its clinical routine use that are under investigation. In the current work, the feasibility of using a normoxic polymer gel dosimeter named MAGICA has been investigated for use in our clinical brachytherapy applic...
