Depends on what doctor you wish to see.I woke up one morning and was unable to see out of my right eye. Went to the Esnaf, diagnosed detached retina. Cost of diagnosis 50 ytl.Only 3 doctors in Turkey can perform this operation.Went to the one who works in Bursa.Medical check up,2 nights private ward in private clinic, 1 hour operation, laser treatment after operation and laser treatment on other eye to prevent same problem, 3 folllow up check ups.total cost 5000 YTL (approx 2000 pounds when operation was done). Can now see reasonably well out of the eye, almost as good as before the problem. Same treatment in private hospital in the UK about 3 times as much. Unlikely you would get it done on the national health in the short time scale that you have to avoid blindness.
