The first thing we want to know is how the dry eye problem is affecting you. We want to know the subjective assessment of where you’re at. We do this by simply chatting to you and finding out how different aspects of your life are affected. There are also some great dry eye questionnaires that give us a lot of useful information, apart from anything else we get a numerical score of how severe your dry eye is and this is a really valuable way of tracking how successful any intervention is. The questionnaire we use is OSDI (Ocular surface disease index). You can download it from here if you want to keep track of your own score. There is also a version as an app at the iTunes store
Once we know how much your dry eye is affecting you we move on to more objective measures.
