NHS residents age after surgery for eye complaint (4-11)

I believe the answer is:

near-sightedness

'eye complaint' is the definition.

'nhs residents age after surgery' is the wordplay.
'after surgery' indicates anagramming the letters.
'nhs'+'residents'+'age'='nhsresidentsage'
'nhsresidentsage' is an anagram of 'NEAR-SIGHTEDNESS'.

'for' acts as a link.

I've seen this clue in The Times.
