Abstract

An apparatus and a method for determining a choroidal topography over a region on a retina of an eye of a person are disclosed. The apparatus is also used to determine an effect of an ophthalmic lens design on the choroidal topography. The apparatus includes two individual displays, two optical transfer elements, a measuring device, and an optical filter. The displays provide a retinal stimulus and the optical transfer elements projects the retinal stimulus or a phase map to a region on a retina. The phase map contains a modified retinal stimulus. The measuring device images a choroidal topography over the region on the retina by capturing reflected light. The optical filter separates the reflected light from the projected phase map. Further, the second optical transfer element simultaneously projects the individual phase maps at a different retinal eccentricity to a peripheral region and a foveal region of the retina.
