The Angle of Error is the difference of angle between the SIA and the TIA and represents the rotation of the Surgically Induced Astigmatism in reference to the Target Induced Astigmatism.
This function calculates the standardized Graph H detailed in the Journal of Refractive Surgery(1) from a single vector that contains the Angle of Error from the sample.
The Refractive Analysis is an Open Source Toolbox for Matlab developed by Rodríguez-Vallejo M for the Analysis of Vision Science Results. It is freely available for the students of our online course but you need the Matlab software to use it. Matlab software is not provided with the course.
The course is asynchronous which means that it has no start or end date. The student can register whenever he wants and view the materials at his own pace.
After purchasing the course you will have lifetime access to the materials through the Udemy platform. This means that even if you complete the visualization of all the materials you will be able to access them again whenever you want to go over the content again or to the updates.
When you complete the visualization of all course materials, Udemy will provide you a certificate of course completion. You will not have to take any tests to obtain this certificate, only complete the viewing of the materials.
