  So POV-Ray is thus behaving exactly like you wanted. What is, then, your
problem?

I know, but I'm not going for realism here :)

Nevertheless, is there any way to achieve this effect without me having to
remove the back of the object?

You can replace it with a flat surface. There will be a refraction, but it will 
be uniform. It may be the best compromise available to you.
For that, you can rework your removal tool into a replacing one, or you can 
difference the mesh with a plane. For that last one, the mesh must be completely 
closed and every faces must be correctly oriented, the inside vectors all toward 
the actual inside of the mesh.
