The short answer is "it depends". Certainly the condition should be checked out by your eye doctor. Standard recovery checkups for post-Lasik surgery are at 1-day, 1-week, 1-month, 3-months, & 6-months. This planned follow-up visit can be changed at any time by the doctor that is providing the care to monitor your healing-up phase. If it's been 5 days, then your 1-week progress visit is probably already scheduled within the next 48 hours, so be sure to bring up your blurry vision as a concern at that time. However! If you are experiencing any sort of PAIN, or if the blurriness is WORSENING, then DO NOT WAIT! Pain and/or worsening vision can be symptoms that you are experiencing a complication from surgery and need immediate attention. What you should do if that's the circumstance; 1) phone the office of the doctor providing your follow-up care and let them know that you need to be seen asap. They are trained to provide this care. 2) Lube, lube, lube - add copious amounts of non-preserved artificial tears until you are seen by your follow-up doctor. 3) If you are not able to see your follow-up doctor, or the surgeon, then go to the Emergency Room and request to see the eye doctor on call. This is not a "wait and see what happens" kind of condition. Hope that helps!
