This was one of the best decisions I've ever made. I came to this particular clinic because of all of the positive reviews. They were not wrong. Most if not all the staff speak English and their bedside manners are wonderful. They're super helpful and double check your condition to make sure you which procedure would be safest for you, if any.
The pre-operation tests were very thorough and the operation itself was only about 10 pain-free minutes. One of the nurses even held my hand as well as gave me a plush doll to hold to calm my nerves.
Overall, I'm totally satisfied. I definitely recommend Dream Eye Clinic in Gangnam.
