Decentration is a term given to describe 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. Complications related to small amounts of laser decentration may result in blurred vision and glare, that is worse at night. Severe decentration can lead to ghost images or double vision. However, there are surgical techniques available to treat decentrations and restore good functional vision.
