How long does refractive surgery last?
With modern LASIK, the enhancement rate is 1-2 percent in the first 12 months and then about 1 percent a year after that as patients’ eyes can change with time. So, for example, 10 years after LASIK, approximately 10 percent of patients may require an enhancement procedure to maintain their excellent vision.13 мая 2016 г.

Is refractive surgery safe?

A refractive error occurs when the shape of the eye prevents light from focusing directly on the retina. This can be caused by a number of things, such as the length of the eyeball being too long or too short, changes in the shape of the cornea, or a result of aging. Thankfully, refractive errors are treatable.
