According to the official website, there are no issues with EyeSuite and Dicom. In fact, it's specified that the EyeSuite is a DICOM compatible product. Here is what it says about this:
"EyeSuite supports DICOM for easy integration and communication throughout your clinic network." - http://www.haag-streit.com/haag-streit-uk/products/haag-streit-diagnostics/eyesuite/
However, since nothing is perfect, issues might appear due to an unlimited number of causes, but if you acquire the product, Customer Support should help you with anything that might came up.
