You are through to Dr Coles, a UK based vet.
Yes you can send through a photo of Darko's eye. Does he seem bothered or painful with the eye? When did you first notice this problem?
That does appear to be the third eyelid which is protruding. It is quite red and inflamed. You mentioned that he had a cherry eye surgery for the other eye. This could be the same problem in this eye. It is not possible to make a diagnosis without seeing him and examining the eye properly but it does look like a prolapsed nictitans gland (cherry eye). I would recommend having him seen by his vet in person as soon as possible as he may need drops to reduce inflammation, etc.
