I recommend Samsung Eye Clinic located in Jamsil.

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 patients feel they should receive treatment at this hospital. It is a hospital that earns trust through meticulous individual diagnosis and treatment. Post-surgery care is also provided kindly and thoroughly, so I recommend it.
