Abstract
The different possible optical aberrations, taking the visualization of the anterior chamber with contact glass as an example. Because the observation beam passes the cornea at oblique incidence, astigmatism of oblique incidence occurs. The astigmatism of oblique incidence is decreasing with increasing slope of the chief ray because incidence on both corneal surface is reduced. In some cases, a steep chief ray may pass through a senile corneal arch, thus increasing light scatter and image degradation.
