What to do with blurred vision

I recently heard about a question about how to handle patients with blurred vision who might have cataracts. Cataracts are one of the most common causes of blurred vision, so it is a common occurrence for patients to come in with blurred vision and for us to find cataracts as the cause. When I plan for cataract surgery, I require a bunch of tests that I need on the patients before they are truly examined. So, if the patient has blurred vision and might have a cataract, is it best to go ahead and do all those tests “just in case” a cataract is the cause of blurred vision? The problem is that it takes a lot of time to do those tests, and it makes patients think that they have surgery-ready cataracts when in fact they may not. So, do we do the “just in case” tests? It is a good question to think about!
