Before the laser vision correction procedure of LASIK many patients have the same question: Is LASIK permanent? It is a very natural question put forth because unlike glasses or contact lenses which are temporary solutions is lasik permanent treatment. Patients want to know if the improvement is permanent, if their vision issue will return, and if indeed the surgery is permanent before they decide to go ahead with the treatment.
The fact is that what happens is lasik permanent. When the laser removes very specific layers of the cornea that process is not reversible. Thus when patients ask is lasik permanent the answer is that it is in terms of the changes which we see in the cornea. At the same time though, permanent is a relative term here. The natural aging of the eye isn’t affected which means that the lens, tear film, retina and in general the health of the eye may still see changes over time.
This is that which we present as a better response to the question of is is lasik permanent which also goes into more detail. LASIK does permanently correct your base refractive error, but it does not fix age related changes like presbyopia, cataracts, or inner lens changes of the eye. At ASG Eye Hospital we guide our patients with this practical info which in turn sets realistic expectations for what they may experience pre and post LASIK eye surgery.
How LASIK Works
LASIK is a form of refractive surgery that we use for the correction of common vision problems like myopia, hyperopia and astigmatism. In the procedure of LASIK eye surgery the doctor makes a thin flap of the cornea which we then use an excimer laser to restructure the underlying corneal tissue. That restructuring of the cornea which in turn improves how light hits the retina and in that way we see better and are less dependent on glasses and contact lenses.
When patients ask is lasik permanent procedure the answer is in the fact that the laser performs a structural change. It doesn’t just temporarily alter the eye’s focus or the surface of the cornea. What it does is change the corneal curvature which is a more permanent condition. That is the reason we consider the results of LASIK to be long term and stable for appropriate patients.
| What LASIK changes | Is the change permanent? | What patients should understand |
| Corneal shape | Yes | The laser reshaping is intended to permanently correct the existing refractive error. |
| Removed corneal tissue | Yes | The removed tissue does not naturally grow back to the old prescription. |
| Age-related near vision | No | Reading vision can change after 40 due to presbyopia, even after LASIK. |
| Cataract formation | No | Cataracts can still develop with age and may affect vision later. |
| Dryness or tear quality | May vary | Dry eye symptoms can occur during lasik recovery and may need treatment. |
So, is lasik permanent?
In the case of changes we see in the cornea, is LASIK permanent? Well yes, it is. The procedure which is corrective in nature and very precise, is meant to be a permanent solution. Many patients enjoy years of clear distance vision post op, also if they had a stable prescription pre op and did pass all pre op screens.
But that said, if the issue is will vision stay the same throughout the rest of your life the answer is no. The eye is a live organ. It does continue to age. This is what many patients do not understand in regards to LASIK surgery. While LASIK may be a permanent solution for some, other natural eye changes will cause vision to change over time.
For instance at age 25 a person may have great distance vision post-LASIK. In their early to mid 40’s they may begin to require reading glasses due to presbyopia. This is not to say that the LASIK has failed. What is happening is the natural lens in the eye is losing its flexibility with age.
Why Some People Need Glasses Again After LASIK
A patient may put forth the question that if is lasik permanent solution, why at times do we go back to wearing our glasses. The cause is that not all vision changes in the future are a result of the cornea. Some changes come from the lens, the retina, the tear film, or health issues like diabetes. In some patients we see mild regression which is more common when the original prescription was very high. By regression we mean a return of some of the previous refractive error which happens over time. This is not the same as the LASIK results going away totally. It is a small change which may be corrected with glasses, contact lenses, or an enhancement procedure if the cornea is still a good candidate.
Another typical reason is presbyopia. This age is related to the near vision issue which almost all people get into whether they have had refractive surgery or not. We as health care professionals when asked if LASIK is permanent we should tell that out of the distance vision it does what LASIK does which is to correct, but does not put a stop to the natural process of requiring reading correction which comes in at around 40. Also to note is that Cataracts play a role later in life. A person who had a successful LASIK decades ago may develop cataracts in their 50’s, 60’s or later. In that case the issue is a cloudy lens which is the cause of vision reduction not failure of the LASIK. Cataract surgery is still doable after LASIK but the doctor will require an accurate history and special lens calculations.
Long-Term LASIK Results
Long in the tooth studies report that many patients do in fact keep good vision years out from under LASIK, although some do see small changes in their prescription. As for the question is LASIK permanent, we tell patients that long term results which are successful do in large part depend on proper patient choice, stable pre op prescription, healthy corneas, and setting realistic expectations. Also the FDA reports that LASIK is for reducing dependence on glasses or contact lenses which is a primary goal of the procedure not for perfect vision for a lifetime. It is also important to note that permanent correction from LASIK should not be looked at as a promise that your eyes will not have any issues in the future.
At ASG Eye Hospital, the purpose of the pre-operative evaluation is to decide whether a patient is a safe and suitable candidate. A good result starts before surgery, not after. Corneal thickness, corneal shape, dry eye status, prescription stability, pupil size, and retinal health all matter.
| Factor | How it affects long-term LASIK results | Why it matters |
| Stable prescription | Reduces the chance of future power change | Patients with changing numbers may not be ideal candidates yet. |
| Corneal thickness | Determines how safely the laser can reshape the eye | Thin corneas may need another refractive surgery option. |
| Age | Influences near-vision expectations | Patients over 40 should discuss presbyopia before surgery. |
| Dry eye status | Affects comfort during lasik recovery | Dry eye should be treated before and after the procedure. |
| High prescription | May carry a higher chance of mild regression | Some patients may need enhancement or alternate options. |
| Eye health | Rules out hidden risks | Retina, cornea, and pressure checks help improve safety. |
What Happens 10 Years After LASIK?
In 10 years out from LASIK many patients still report good distance vision. For appropriate candidates the correction usually is a long term solution. Thus when a patient asks is LASIK permanent in terms of 10 year results the answer is mostly positive. But some patients do see minor changes. A small prescription may return some which was high to begin with. Also some may notice dryness, glare, or have issues with near work based on age and tear quality. That is why follow up eye care is important even with successful results. The question of whether LASIK is permanent should therefore be put forward with balance. The correction done in surgery is permanent but eye care is a lifetime thing. Routine eye exams help to catch any changes early and keep vision at its best.
What Happens 20 Years After LASIK?
In the two decades since the introduction of LASIK most changes in vision are a result of age related processes as opposed to the laser procedure itself. By this time many patients who had LASIK in their 20’s or 30’s may be reporting on the onset of presbyopia or early signs of cataract. This is all part of the natural eye aging process. As for the question, is LASIK permanent after 20 years for the cornea?
The answer is still yes, the laser created changes are not going away. What may have changed is the internal lens of the eye which plays a role in reading vision and later in distance vision if cataract does in fact develop. Also it is important to note that permanent results from LASIK should not be equated with the idea of “this is my only eye care for life” while LASIK does reduce dependency on glasses for the treated refractive error it does not do away with the need for regular eye check ups.
Does LASIK Wear Off?
LASIK doesn’t go away like a medication or contact lens does. What is essentially permanent is what doctors report which is that the laser correction is in the cornea. A better term for later changes is regression, prescription shift, presbyopia, or some other eye issue. We see mild regression in a small group of patients. Also it is more common when the original prescription was high or when healing varies. If the cornea is healthy and has sufficient thickness an enhancement may be done. That decision comes out of in depth testing. As for is LASIK permanent, yes it is, but what is put forward as a final result can still be affected by healing, age, lifestyle, and future eye health. That is why a strong screening process is put in place.
LASIK Recovery and Stability
Good LASIK recovery is key to comfort and early visual clarity. Most patients see quick improvement in their vision, though the eye is still in the process of healing. In the early stages of repair dryness, mild glare, light sensitivity, and fluctuating vision may present. Also during the recovery period patients will ask if LASIK is permanent which is a natural concern as vision does fluctuate for a few days or weeks.
At this stage in healing results may not be stable. In the great majority of cases as the surface heals out vision improves and dryness lessens. We tell patients to very much follow post op instructions. Use of prescribed drops, no eye rubbing, keeping follow up appointments, and giving the eye the rest it needs all play a role in better LASIK recovery. As patients do what is asked of them the picture becomes clearer as the long term results are determined once healing is complete.
Who Gets the Best Long-Term Results?
The in which we see best results are in patients with stable prescriptions, good corneal thickness, normal corneal geometry, manageable dry eye, and realistic expectations. Not all patients are a fit for LASIK which is why we stress the importance of the screening process. A patient may ask if LASIK is permanent but first the question should be is LASIK right for that person. If the cornea is too thin, the prescription is still evolving, or there is keratoconus we may put forward other options than LASIK eye surgery. For some patients SMILE, PRK, ICL, or another refractive surgery may be more appropriate. We do what we do to put forward the best option for each individual which in turn improves long term satisfaction.
Can LASIK Be Done Again?
In certain cases we see patients return for a LASIK touch up which is a small re-treatment of the eye. This is also referred to as a fine tune procedure. That said it is not true for all patients. We do a full work up which includes evaluation of corneal thickness, overall eye health, dry eye issues and the degree of correction required. Also a question we often get is does LASIK last forever. What patients don’t know is that which eyes require a second procedure is few and far between. For the most part what we see is that the initial treatment is the primary one, we do go in for small touch ups in a select few cases. At the end of the day safety is our top priority in making that decision.
LASIK at ASG Eye Hospital
At our practice in ASG Eye Hospital we focus beyond just post procedure clarity of vision after LASIK, we are also dedicated to your safety, stability, and long term eye health. Prior to any treatment each patient goes through in depth evaluation so our doctors may determine that LASIK is the best fit for you or if another type of refractive surgery may suit you better.
The corneal reshaping is permanent however natural aging changes will still take place. We present this info to patients in a straightforward way at ASG Eye Hospital — the corneal reshaping is permanent but natural aging changes can still happen. This we do to help patients make an informed decision which in turn breaks the cycle of their expectations of life long perfect results.
The team also provides for all aspects of your LASIK experience from post op recovery to routine follow ups we also include dry eye management which is very important. Our full service approach is key to long term LASIK success which is a result of not only the procedure but also which patients we choose to do the procedure on, which technology we use, and what we do in terms of post op care.
Key Takeaway
So, is LASIK permanent? In terms of the laser correction of the cornea that is the case. The change which we see with LASIK is meant to be permanent and does not go away. But also as a result of natural aging which includes presbyopia and cataract we may see that vision is affected at a later stage.
LASIK permanently fixes present refractive errors, we just can’t keep eyes in a constant youthful state with it. Through good pre op screening, safe surgery, proper lasik recovery, and regular eye check ups many patients enjoy very long term relief from visual issues.
Before you decide, get a second opinion from your ophthalmologist on if your prescription is stable, if your cornea is a good candidate, and that your expectations are realistic. This in turn makes the question of LASIK being a permanent solution a more valid one which is true for each case.

Frequently Asked Questions
1. Is LASIK permanent?
Yes, what is the permanent aspect of LASIK in terms of the corneal reshaping which the laser does. What we see is that the removed corneal tissue does not grow back in the same way, and the correction is for the long term. At the same time it is true that aging changes like presbyopia or cataracts will still play a role in vision.
2. Is LASIK surgery permanent for everyone?
For in a large number of cases the correction is lasik surgery permanent. But patients with very high prescriptions, unstable numbers, dry eye, or hidden corneal issues may have a greater chance of seeing changes in the future.
3. Can eyesight come back after LASIK?
A small number may notice mild regression which is more common in high degree cases. This does not indicate that the results of your LASIK are gone for good. What we see is that the main correction remains permanent but in some cases we see very minor changes.
4. Will I need reading glasses after LASIK?
Many at 40 and beyond require reading glasses which is a result of presbyopia. This is because the natural lens loses its flexibility with time. It is not a failure of LASIK. This is why we should discuss LASIK lasting results along with age related near vision changes.
5. Can LASIK be repeated?
LASIK enhancement may be possible in selected cases if there is enough corneal thickness and the eye is healthy. The doctor will decide after detailed testing. The need for enhancement does not change the basic answer to is LASIK permanent, because the original laser reshaping remains permanent.
