Dr. Cohen is amazing. I scratched my cornea (that was officially diagnosed later) late Saturday evening, which is the worst time to do it because your options are pretty much go to the hospital or suffer and worry until Monday. I accidentally found Dr. Cohen after trying to contact offices that took emergency calls. Dr. Cohen was incredibly kind, especially since he'd never met me nor did he have any of my insurance information. He asked me about symptoms and coached me through how to care for my eye. He even offered to open up his office for me and stuck around during the day in case it became necessary, answering my call again later when I become concerned about my progress.
I went in to see him on Monday and he again showed great care and was very willing to answer questions and explain diagnosis and treatment to me. He didn't rush at all and made sure to see me back to the front desk after stopping for some samples for me. I've since been in again for my yearly eye exam (yes - I immediately made him my new optometrist)band was impressed yet again. Dr. Cohen is one of the top two doctors I've experienced both in Illinois (incl. Chicago) and Arizona. Couldn't recommend him more!
His staff was also great - even called and made an appointment for me with a doctor at another office when I needed to see a specialist.
