Decentration is a term that describes what happens when the laser is not properly lined up on your eye.
If this occurs, the outcome will vary, depending on the amount and location of the decentration. LASIK eye surgery complications related to small amounts of decentration may result in blurred vision and glare that becomes worse at night. Severe decentration can lead to ghost images or double vision. However, surgical techniques are available to treat decentration and restore good functional vision.
