Hazy, Unclear Post-op Lasik Vision

The analogy I love to use is this: "when you sit up from the Lasik procedure it is like you just got out of the shower and your bathroom window fogged up. As each hour and day go on the fog gets clearer and clearer." So, this is a good expectation post Lasik. There is some variability in the speed of the fog lifting, so predictions are not exact. However, typically, 90% of the fogginess should be resolved in the first 24 hours. There can be a little more fogginess (or blurriness) if your prescription is higher than average. By and large, any swelling induced by the procedure should be far gone after two weeks. Most patients (including myself) can drive during the day on the first day after surgery and at night on the second night. Using this as a guide, you can decide if things are going according to plan. You should always have your eyes checked the day after your procedure. Most patients are 20/20 or very close to it, although the quality of the 20/20 may not be perfect quite yet.

It sounds like you need to see your surgeon and make sure everything is ok. After some reassurance that all is healing well, then some "tincture of time" should do the trick.

Your blurring may go away if you are only six days postop. That's extremely early in the grand scheme of things. Predicting your final result is like predicting the results of a football game after the first five minutes of play.
A common cause of post-LASIK blurring is residual refractive error (ie, astigmatism, nearsightedness or farsightedness which still remains). Glasses would correct this--if the blur is severe, have your surgeon write you a prescription for a pair of glasses to get you by while you wait for visual stabilization.
If glasses don't help with the blur, it may be from dryness, in which case artificial tear lubricants will help. It may also be due to corneal swelling, which is relatively common one week postop. In this case, hypertonic saline drops (Muro 128) might be helpful to improve the vision. Occasionally, there can be inflammation in the cornea which would respond to a longer than usual course of anti-inflammatory drops.
Higher starting prescriptions are associated with both a longer stabilization period, and larger swings in the vision during this period, as well as a higher chance of needing a touchup or enhancement procedure.
At this relatively early stage of healing, be patient, and follow your surgeon's instructions. It can take up to three months for the vision to fully stabilize. I always tell patients it's not at all important what your vision is on day one or week one... far more important what it is at the three month mark, when things are fully stable.
