Good dr. He did my cataract surgery.
I feel blessed to be Dr Ahn's patient
Dr. Ahn is the best ophthalmologist hands down. He is honest and answers all questions and the surgery he performed gave me perfect vision in my eye which was botched by another surgeon. Thank you Dr. Ahn.
The staff and doctor were extremely helpful and informative about the exam and about the treatment I will be having
Good
