Haigis Formula for IOL power calculation
Updated on version: 1.0.5


This function calculates the power of the Intraocular Lens (IOL) according to the Haigis formula. It also returns parameters useful for optimizing the constant or calculating the prediction error.


Haigis Formula for IOL power calculation


This function calculates the power of the Intraocular Lens (IOL) according to the Haigis formula. It allows to obtain parameters such as:

  • Power of the IOL close to emetropia.
  • Effective lens position of the intraocular lens (IOL) predicted by the formula.
  • The target or residual sphero-equivalent predicted by the formula.

The function also allows to compute the same parameter for the Haigis-L in eyes after myopic laser refractive surgery.

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.
