I have myopia in Chaozhou opera, and I have femtosecond. I looked up a lot of information and asked my classmates before I did it, so I chose Tide Gathering, because femtosecond only exists in Tide Gathering. Ask Chaoju in the Second Hospital first, and then ask Chaoju. At that time, Chaoju was much older, so I had a bottom line. As far as that equipment is concerned, what s4 is used for the super residence, not s2 as mentioned by the Second Hospital. I saw the machine because it was an ophthalmic operation. Chao Ju said that this is their most common operation. I think the equipment of hospitals specializing in ophthalmology must be the same. Otherwise, something would have happened. Haha, I didn't say it until I saw your question. Now I'm recovering very well. You should ask for it yourself. It's better to be cautious. Say so much, give me a score. I won't say anything without reading so much, for fear of being told to advertise. Hee hee, there are still some things I don't understand.
