Doctor works treating eyes perhaps (5)
I believe the answer is:
drops
'treating eyes perhaps' is the definition.
I can't judge whether this defines the answer.
'doctor works' is the wordplay.
'doctor' becomes 'dr' (abbreviation).
'works' becomes 'ops' (op is short for opus, a work).
'dr'+'ops'='DROPS'
Can you help me to learn more?
(Other definitions for drops that I've seen before include "Lets fall" , "Gives up" , "Delivers" , "treatment for eyes" , "treatment for eye" .)
