I recommend Haeundae Udong St. Mary's Eye Clinic.

This is a hospital located at the entrance of the Seoul Metropolitan Museum of Art Station on Subway Line 2 in Haeundae U-dong.

It is a large specialized ophthalmology hospital and is quite well-known in Busan.

Whenever there's a problem with my eyes, I always run here.

I received treatment for allergy symptoms, and with various tests and consultations, I am now almost fully cured.

There is also internal medicine in the departments, so you can receive internal medicine treatment as well.

If you live in Busan, I recommend St. Mary's Eye Clinic.
