Very good. My partner and my cousin did it in less than a minute with a laser. First, they put on eye drops, and then the patient's eyes looked at a point in the instrument for a few seconds, and it was ok. Then they rested for a few days. Don't overdo it. Don't watch TV, surf the Internet and eat fishy food. Just stick to it for about ten days. The postoperative effect is quite good. Oh, by the way, it is not suitable to drive at night at first after the operation. My partner said there was a little ghost. It will be fine after a while during the day.
