Is Lasik a permanent solution for myopia, hyperopia, and astigmatism?
2 weeks ago
I’ve been wearing glasses for more than a decade, and lately they’ve started to interfere with my daily life especially when I’m traveling, working long hours on the computer, or playing sports. I’ve been reading about lasik but still don’t understand the actual science behind it. How exactly does lasik reshape the cornea, what vision problems can it correct, and is the improvement truly permanent or does the effect fade over time?

Lasik is a game-changer for folks tired of glasses during travel, long computer sessions, or sports. It’s all about reshaping your cornea, the clear front dome of the eye, so light hits the retina perfectly instead of blurring. A femtosecond laser creates a thin, hinged flap on the cornea (blade-free in modern versions), which the surgeon lifts gently. Then an excimer laser vaporizes tiny bits of underlying tissue in a custom pattern: flattening the center for nearsightedness (myopia), steepening it for farsightedness (hyperopia), or smoothing irregularities for astigmatism. All guided by your eye’s map for precision, taking just 10-15 minutes per eye.
The improvement is permanent for the vast majority because corneal tissue doesn’t regenerate or revert once reshaped over 95% keep crisp vision long-term without fading. That said, natural aging like presbyopia (needing readers after 40) can creep in, or rare regression might need a touch-up. A full screening confirms if it’s right for you, but for active lifestyles, it’s often transformative.
