The emmetropic model eye is currently limited to an accommodation of between (approximately) 1.2 and 8 diopters.

Fixing this would require improving the model of the lens, which is currently an ungainly mix of model elements from different sources.

Hi! I found this library from someone on IRC, and I'm interested in trying it out.

I'm afraid I can't get it working.

>> cd ~/local/repos/gkaModelEye/demo/
>> DEMO_eyeRotationGifs
Unrecognized function or variable 'createSceneGeometry'.
Error in DEMO_eyeRotationGifs (line 3)
sg = createSceneGeometry;

sceneGeometry.eye = modelEyeParameters('spectralDomain',p.Results.spectralDomain,varargin{:});
Error in DEMO_eyeRotationGifs (line 3)

This is on Matlab R2019b.

Could you add a short document explaining how to load this library in to Matlab, and how to call it?

Cheers,

Dear Professor Geoffrey K Aguirre,

My name is Phu Do-Tuong, I am a master student in the Department of Biomedical Engineering, the Faculty of Applied Sciences, Ho Chi Minh City University of Technology - VNU HCMC.

Thank you for your fantastic-open-source work. Could we implement the model to binocular vision?

Student name,

The IOL Master is used to measure the axial length of the eye. The subject is asked to fixate a red point, and the axial length is measured along the axis that connects the fovea to that measurement location. Therefore, the device reports the axial length of the eye along the visual as opposed to optic axis of the eye. This will lead to a slight over-estimation of the length of the eye.

Need to understand this more completely and, if necessary, do some quick trigonometry in the the modelEyeParameters routine to adjust.

The modeled contact lens front surface should be elliptical, and not spherical. Need to fix this.
