Outline of cornea is wrong (8)
I believe the answer is:
scenario
'outline' is the definition.
(I've seen this before)
'cornea is wrong' is the wordplay.
'wrong' indicates anagramming the letters.
'cornea'+'is'='corneais'
'corneais' anagrammed gives 'SCENARIO'.
'of' is the link.
(Other definitions for scenario that I've seen before include "Dramatic set-up" , "Projected sequence" , "Master plan" , "Imagined sequence" , "Envisaged situation" .)
