- Primary Outcome Measures
Name Time Method <p>1. Ocular geometry measurement using MRI imaging and ocular biometry<br /><br>The main study parameters are the 3D-shape of the eye and the distances and<br /><br>curvature between the front and back cornea, the front and back of the<br /><br>crystalline lens, the equator of the eye, the retina and the sclera. From these<br /><br>parameters we will derive the variation between those parameters within the<br /><br>group and correlate them to the results from the current ophthalmology<br /><br>measures.</p><br>
- Secondary Outcome Measures
Name Time Method <p>2. Clinical method to evaluate natural peripheral vision in patients.<br /><br>The main study parameters are visual acuity, refraction, central and peripheral<br /><br>wavefront measurements.</p><br>
