Cleveland Clinic publicly discloses the names of companies when (i) its physicians/scientists receive $5,000 or more per year (or, in rare cases, equity or stock options) for speaking and consulting, (ii) its physicians/scientists serve as a fiduciary, (iii) its physicians/scientists receive or have the right to receive royalties or (iv) its physicians/ scientists hold any equity interest for the physician's/scientist's role as inventor, discoverer, developer, founder or consultant.* In publicly disclosing this information, Cleveland Clinic tries to provide information as accurately as possible about its physicians' and scientists' connections with industry.

Was very responsive to concerns about my contacts prescription and specific changes that I had noticed. I also had some complicated questions about my insurance, since it's changing next year. Although Dr. Sax didn't know the answer, he connected me with someone who could really answer my question well.

The Clinic scheduled the appointment for me as a follow up to cataract surgery, therefore I did not call the appointment line. I have been very disappointed in the call center and instead go directly to the physician's office to schedule appointments.

excellent doctor, and excellent staff

Rating ability to see provider of choice as poor because I scheduled an appointment online to see an Opthamologist for contacts. I was not made aware of the difference in providers for contacts and glasses, and as a result, I was not able to see a contact lenses provider the original date and time of my appointment.

Reviewed on Aug 9, 2018

Again, my original appointment was scheduled with an eye glasses provider. LUCKILY, the nurse I had was extremely helpful. She ran over to see if a contacts physician was available, and luckily Dr. Sax accepted me on the spot.

Dr. Sax diagnosed my problem almost immediately. I had been complaining about my sight to my prior Dr for the last 3 years and he was never able to help me. Dr. Sax spent a lot of time helping me find the right contacts. He even ordered a trial pair of a specific contact that he didn't have in stock. He's the best!
