    Dr. Sun is very knowledgeable and professional when diagnosing my eyes. She thoroughly evaluated my medical history and consulted my primary care physician and other doctors before recommending the best treatment for me. She had her assistants find the best available time for my next visit. I am very fortunate and grateful to have such able and caring doctor.

    Dr. Sun figured out that a stitch in my eye was the source of the almost constant irritation I'd been experiencing for 14 months and was able to remove it. My eye now feels 100% better and my friends notice that it looks more normal.
