What if it doesn t work as well as it should?
While laser treatments are highly accurate when fired into plastic testing plates, plastic doesn t heal and change shape afterwards, as some patients do. There is always the possibility that the initial treatment will not adequately correct the refractive error. This most is apparent immediately, is not usually of such a magnitude that it requires glasses correction, but needs to stabilize before being addressed by an enhancement procedure. This stabilization period is typically three months for nearsighted patients and six months for farsighted patients. This explains why 75% of all retreatment procedures occur within a three to six month period postop. A few patients we do well initially but slowly change over a longer period of time as their personal healing may affect the result. We will wait until this stops and, again, perform an enhancement as needed (99% of all retreatments occur within the one year period).
