Background and purpose: Astigmatism is a common optical dysfunction, effective on various visual outcomes and one of the important criteria of refractive surgery. The aim of present study was to evaluate the correlation between refractive, corneal and residual astigmatism in refractive surgery candidates. Materials and methods: In this cross-sectional descriptive, analytical study, 200 patient...
BACKGROUND As new methods for corneal curvature measurement have evolved, users of videokeratscopes need to know the practical limitations of these instruments. We assessed agreement between keratometry and videokeratography in measuring highly astigmatic corneas. METHODS Two independent examiners made three keratometric and videokeratographic measurements on each of 33 corneas after penetrat...
Aim: To investigate and compare the effects of pterygium surgery on mean anterior surface Simulated Keratometry (SimK) Holladay Equivalent Readings-65 (EKR65) detail report.
 Methods: Patients who underwent between August 2022 January 2023 were examined. All surgeries performed under local anesthesia with conjunctival autograft method. Pentacam topography was after detailed ophthalmologica...
PURPOSE Corneal tomography is used to assess progression of keratoconus and to direct clinical decisions regarding corneal cross-linking. The purpose of this study was to analyze the variability of repeated Scheimpflug-tomography (Pentacam Classic; Oculus, Wetzlar, Germany) measurements of keratoconic eyes in a clinical setting and to assess the validity of such measurements as a clinical decis...
Dual-specificity mitogen-activated protein kinases kinases (MAPKKs) are the immediate upstream activators of MAPKs. They simultaneously phosphorylate the TXY motif within the activation loop of MAPKs, allowing them to interact with and regulate multiple substrates. Often, the activation of MAPKs triggers their nuclear translocation. However, the spatiotemporal dynamics and the physiological con...
AIM: To analyze the differences, agreements, and correlation among total corneal power parameters generated by different instruments after myopic keratorefractive surgery. METHODS: The prospective cross-sectional study included patients who underwent surgery received measurements of 3mo Automated keratometer was used for measurement simulated keratometry (SimK), swept-source optical coherence t...
Excessive amounts of heavy metals adversely affect plant growth and development. Whereas some regions naturally contain high levels of heavy metals, anthropogenic release of heavy metals into the environment continuously increases soil contamination. The presence of elevated levels of heavy metal ions triggers a wide range of cellular responses including changes in gene expression and synthesis...
Background and Objective: Proper method and machine for corneal evaluation is an important factor in many anterior segment interventions. This study was performed to compare the mean keratometry (K) readings obtained with an IOL Master and Pentacam for intraocular lens power calculation in normal subjects with no history of refractive surgery. Materials and Methods: Mean K values were obtained ...
PURPOSE To investigate normal anterior segment parameters and analyze the possible influencing factors using a dual Scheimpflug system. SETTING Department of Ophthalmology, Affiliated Sixth People's Hospital Shanghai Jiao Tong University, Shanghai, China. DESIGN A prospective observational case series. METHODS A total of 153 normal subjects (153 eyes) were studied. The anterior segment pa...
This study aims to analyze and identify the implementation of Financial Management Information System (SIMK) at PT. Pojur. The research was conducted using qualitative methods case studies as a approach. Data were obtained through in-depth interviews with SIMK users Pojur analysis documents related use in companies. results showed that has had positive impact on company's financial management. ...
