I'm not sure if this topic goes under Surgery, but I suppose so, since it's opth-related.
I have a clinical opthalmology exam next tuesday. In Aphakia, there supposed to be no Purkinje Sanson images seen, while in Pseudophakia, 2 images are seen. In normal persons, 4 images are seen.
Now what exactly are those images? and how can they been seen using only the ophthalmic light torch?
I'd really appreciate your help!!
the four images are:
1 - reflection from the anterior cornea
2 - reflection from the posterior cornea
3- reflection from the anterior lens
4- reflection from the posterior lens
only the 4 th image is a real image
and 2,3,4 have a component of refraction in them
