Why Do Some Patients Regress Years After LASIK or PRK?

LASIK/PRK  should not regress years after surgery. Regression  related to wound healing or energy absorption should occur within the first year.  Unfortunately, LASIK/PRK does not prevent eye disease nor does it prevent changes in the eye caused by aging. As we all get older the lens inside the yellows (nuclear sclerosis) inducing nearsightedness or myopia. This normally occurs above the age of 60 but can occur earlier. There is also some suggestion that patients with untreated dry eye are at greater risk for regression.
