Does LASIK wear off? What do we know about long-term effects of LASIK? It’s been around 25 years – is that really enough time to discern long-term effects?
Yes, it would appear so. There are rare changes that have been observed up to 2 years after treatment (and which are treatable), otherwise we haven’t seen any other effects, even over the following 20 years.
We know that the cornea gets stronger with age due to the action of ultra-violet light, hence the long-term safety profile as we get older seems excellent. Additionally, based on the physiology of the cornea we don’t conceive of a mechanism where late changes in focus can occur after excimer laser treatment.
At Focus, we have only seen a return of short-sight after the 1 year standard aftercare period in 1 in 800 cases, or 0.125%
It is important though to ensure your prescription is stable before surgery. At Focus Clinic, we have only seen a return of short-sight later on (after the 1 year standard aftercare period) in 1 in 800 cases, or 0.125%. Our lifetime care guarantee means we retreat such rare cases in the first 10 years post treatment, for free.
Long-sight however is an age-related condition, so even if the LASIK treatment is fully stable, the effect of the surgery will decline as the problem progresses over time.
