My Brother experience at GS Eye Center he said the clinic was very advanced in handling genetic testing for retinal diseases. The doctors including Dr Kim Moo-Yeon guided him step by step through the testing process starting with a full eye exam then moving to genetic counseling and lab tests He felt that everything was explained in a way that was easy to understand which helped reduce his worries. The results gave him clarity about his condition and how to manage it better. My brother felt well supported and appreciated the professionalism and kindness of the staff For anyone seeking genetic testing for retinal problems.
