Slightly concave is the preference just like human eyes.  As for PBR, some users are incorporating a glass shader as opposed to a glossy one for eye work.

For the cornea, I'm using this shader that you taught me. Since the cornea covers the whole eye, I'm hoping it will take care of all the required glossiness.

Just my 2-cents:
I have tested your solution with my Sasha19 (a weightmapped Vic4) and that give the left part below.
On the right part: Ghostship's  explaination (a fewdays ago: using a Blinn node)

The result: we can also see point-like lights, which disappear using Gloss or Glass nodes.
