Jamsil Samsung Eye Clinic is very good.

Samsung Eye Clinic in Jamsil is a hospital staffed by medical professionals trained at Seoul Asan Medical Center and Samsung Seoul Hospital. Each of the doctors is highly skilled. Perhaps due to their extensive experience, even complex cases like glaucoma and cataracts that cause concern can be confidently discussed here, and you will feel that treatment should be done at this hospital. It is a hospital that earns trust through meticulous individual diagnosis and treatment. They also provide kind and thorough post-surgery care, so I recommend this place.
