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...
متن کاملExtent and effect of surface tilt on the data display of the EyeSys videokeratoscope.
AIMS This study examined the occurrence, magnitude, and the consequences of a possible tilt between the corneal surface and optical axis of the EyeSys videokeratoscope. METHODS Initially, a theoretical model was developed to calculate the angle of tilt. The predictions of the model were verified empirically using a convex conicoid surface and were found to predict the tilt to within 0.5 degre...

15 صفحه اولcomparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.
heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...
15 صفحه اولa comparison of teachers and supervisors, with respect to teacher efficacy and reflection
supervisors play an undeniable role in training teachers, before starting their professional experience by preparing them, at the initial years of their teaching by checking their work within the proper framework, and later on during their teaching by assessing their progress. but surprisingly, exploring their attributes, professional demands, and qualifications has remained a neglected theme i...
