Kim Eye Hospital in Seoul specializes in eye care and is a five-minute walk from Yeongdeungpo Station Exit 5. It handles glaucoma and retinal care as well as double eyelid and fat removal surgery. Appointments start at 8:30 a.m., same-day registration opens at 8 a.m., and booking through KakaoTalk is available. The main drawback is that visiting without a reservation means waiting more than an hour.
