Clears out the white of the eye (6)
I believe the answer is:
sclera
'white of the eye' is the definition.
(I've seen this in another clue)
'clears out' is the wordplay.
'out' indicates an anagram (out can mean wrong or inaccurate).
'clears' with letters rearranged gives 'SCLERA'.
'the' acts as a link.
(Other definitions for sclera that I've seen before include "part of the eye" , "tissue in the eye" , "Eyeball's outer cover" , "Membrane" , "Bit of a looker" .)
