Laser eye surgery permanently reshapes the cornea, and for most people, the improvement in distance vision is long-lasting. In that sense, LASIK is permanent; the laser surgery outcome on the cornea does not “wear off”, and LASIK, LASEK and SMILE results are generally very stable over many years.
However, your eyes still age naturally. Conditions like presbyopia (needing reading glasses in your 40s or 50s) or cataracts later in life affect a different part of the eye, not the cornea treated during LASIK or SMILE. Some people may need need glasses or retreatment over the following 10 years as their eyes changed with time, not because the original laser eye durability failed, but because their vision continued to evolve.
If your prescription changes or you notice a shift in clarity years later, an assessment can confirm whether a LASIK enhancement, SMILE touch-up or another option is appropriate.
Can Vision Change Over Time?
Yes, your vision can change over time, even after excellent Birmingham LASIK results. These long-term LASIK effects are usually due to ageing after LASIK, such as the lens becoming stiffer (presbyopia) or the development of cataracts, not a loss of laser vision longevity.
Most patients enjoy very good post-laser correction stability, especially when their prescription was stable before surgery, and they attend regular check-ups. If changes occur, your laser eye surgeon will review your long term eye health and discuss whether a safe LASIK revision or alternative procedure could fine-tune your vision correction timeline. Good LASIK aftercare and ongoing eye care help you maintain clear, comfortable vision for the long term.
