I have found the OPD to be an invaluable tool for both pre-operative and post-operative evaluation of our patients. The diagnostic summary allows me to assess and confirm the need for toric IOLs and limbal relaxing incisions and we now perform this as part of our preoperative work up in most of our cataract patients. The wavefront refractions have also been extremely reliable and helpful for our difficult refractions in pathologic eyes. Our technicians find it easy to use and everyone is pleased with the additional diagnostic information available.
