Are the results of LASIK permanent?

It is permanent only up to the day you develop cataracts. The average age of symptomatic cataracts in Singapore would be 60 years old. At about 60 years of age, you will develop some blurred vision at near or at far distance because the lens inside your eye has turned white or cloudy. Therefore, LASIK can only last until the day your cataracts set in. The earlier you do your LASIK, the more mileage you get from it.
