I've said it before, but I didn't know what to do with my first pair of hands, so I just went to a famous and big place. My eyes are factory-type.. Everyone will know that you look at my eyes. Anyway, this time, I looked for a hospital with my eyes on fire, and there was no place to sell hands-on products, and because of the trauma of a large hospital, I mainly looked for private hospitals, and I met a director who paid a lot of attention to after-sales care and design . I will write down 1. 2 years as free of charge (including simple dissatisfaction) 2. The director is very delicate 3.. There were many more reasons such as catching the desired part and identifying the problem well, but if you guess it like this, it's probably because you are an eye specialist. I don't know, but he explained the structure of the eye and the line that suits him very well and found him well. For reference, it's been a little over a month since I underwent revision surgery, but my impression has changed drastically and has become much more natural.
