I believe the answer is:

periscopes

I'm a little stuck... Click here to teach me more about this clue!

'require devices that can see round corners' is the definition.
I can't tell whether this definition defines the answer.

'complex precise ops' is the wordplay.
'complex' indicates an anagram.
'precise'+'ops'='preciseops'
'preciseops' anagrammed gives 'PERISCOPES'.

Can you help me to learn more?
