Assessment and Statistics of Surgically Induced Astigmatism [PDF]
Acta Ophthalmologica, 2008 The aim of the thesis was to develop methods for assessment of surgically induced astigmatism (SIA) in individual eyes, and in groups of eyes. The thesis is based on 12 peer-reviewed publications, published over a period of 16 years. In these publications older and contemporary literature was reviewed(1). A new method (the polar system) for analysis of

Surgically Induced Astigmatism After Cataract Surgery – A Vector Analysis [PDF]
Current Eye Research, 2022 Surgically induced astigmatism (SIA) has been widely discussed in the literature as the change in corneal astigmatism resulting from corneal incision. The purpose of this study was to investigate the change in corneal refractive power preoperative to postoperative using a vector analysis of keratometry, total keratometry, and corneal back surface data ...

Astigmatism analysis and reporting of surgically induced astigmatism and prediction error
Journal of Cataract & Refractive Surgery, 2022Purpose: To provide a method for determining the vector that, when added to the preoperative astigmatism, results in no prediction error (PE) and to specify statistical methods for evaluating astigmatism and determining the 95% confidence convex polygon ...

Evaluating surgically induced astigmatism
Journal of Cataract and Refractive Surgery, 1994Using a modification of vector analysis for calculating surgically induced astigmatism, we describe a simple method that divides the induced cylinder into two orthogonal components. This decomposition allows with-the-rule and against-the-rule astigmatic changes to be calculated for individual case analysis, as well as for statistical analysis of ...

[Calculation of surgically induced astigmatism].
Nippon Ganka Gakkai zasshi, 1995We compared several mathematical methods for the calculation of surgically induced astigmatism, including Jaffe's horizontal component, Jaffe's vector, Cravy's axis-based cylinder, and Holladay's with-the-wound cylinder. Computer stimulation indicated that Jaffe's vector and Holladay's with-the-wound cylinder methods correctly calculate the surgically ...
