The effects of laser eye surgery are permanent, and regression following laser eye surgery is extremely rare.
That does not mean, however, that a patient’s eyesight will not change naturally over the course of time. An inevitable consequence of growing older is the onset of presbyopia. Literally meaning ‘old eye’, this condition refers to the natural stiffening of the lens of an eye, which affects a person’s ability to focus on objects. This condition generally becomes noticeable as we reach middle age regardless of the prior health of our eyes.
Laser eye surgery has no bearing upon the onset of presbyopia, although a technique known as laser blended vision has been developed which can alleviate the condition.
