This function detects defocus curves that do not have their maximum peak of visual acuity or contrast sensitivity at 0 D (infinity) in a dataset, corrects the shift and calculates de effective addition


Defocus Curve Shift Correction and Effective Addition


This function detects defocus curves that do not have their maximum peak of visual acuity or contrast sensitivity at 0 D (infinity) in a dataset. It also corrects those shifted defocus curves so that they all have the best peak of vision at 0 D before performing a descriptive statistical analysis. The function also allows you to calculate the effective addition calculated as the difference between the two peaks of best vision in bifocal or trifocal intraocular lenses.

Online Course

How to obtain the Toolbox?

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.

How to enroll and follow the course?

You can enroll in the course by means of the Udemy Platform and follow the course on the same platform or through Udemy App for IOS or Android.

When the course starts and finish?

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.

Will I have a certificate once I finish the course?

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.
