We love Dr. Cho. He is very patient with my son. My son has very specially needs for his eyes and he is explained his situation in details. He didn’t give ys any false hope as its very expensive but he was very optimistic because he is young. After a week of wearing orthoK lenses, my son’s vision improved drastically. So much better than when he was wearing his glasses. He answers all the questions based on his professional experiences and observing the trends thats happening to the young generations now. His office is very clean. Staff is always friendly and professional. We 100% recommend Dr. Cho for those who are looking for orthroK. You wont regret it!
