There are two kinds of striae (wrinkles) that affect the Lasik flap. Macrostriae are like a comforter on the bed that is rumpled - big thick wrinkles that are commonly very obvious. Microstriae are tiny crinkles within the flap itself. I compare these to those fancy towels with the appliqué after a few washings. The appliqué has tightened and caused crinkly wrinkles.
As a (very) general rule, macrostriae should be treated earlier rather than later, commonly with a flap lift and repositioning. Microstriae tend to be best left alone and allowed to resolve as they can with healing. If the microstriae are not resolve after the end of the normal healing period, then a flap lift may be appropriate.
With both types of striae, if they are not bothering vision quality then it is almost always best to leave them alone.
You mention vision problems in a low light environment. This may be caused by striae, but not necessarily. At one month postop this can be attributed to the normal healing process.
Your doctor has the advantage of having actually seen your eyes, what type of striae you have, where it is located, and can monitor your progess with subsequent visits.
