Can laser eye surgery be done twice?

Have you ever wondered if it’s possible to have laser eye surgery twice? Maybe your first procedure didn’t go as planned, or maybe your vision has changed and you want to know if you can go under the laser again. Well, look no further! In this article, we’ll explore whether a second round of LASIK is feasible.

Understanding Laser Eye Surgery

Before delving into whether repeat LASIK is viable, let’s quickly review how the procedure works.
Here are some important aspects:

  • Flap Creation: During the operation, a hinged flap on your cornea is created using either a microkeratome blade or femtosecond laser.
  • Laser Reshaping: Once the flap is lifted back, an excimer laser sculpts and reshapes tissue within the cornea to change its refractive power.
  • Flap Recovery: The cut-flap heals naturally without sutures over several days following most conventional surgeries.

Even if traditional LASIK corrects vision problems effectively for many people indefinitely (some up to 20/20), there may still be occasions where one chooses reoperation :

Blurred Vision

LASIK post operative outcomes generally expect good quality eyesight from patients after their procedures however in quite rare cases like infections or sudden trauma it can result in blurred vision.It could diminish patients’ daily routine activities which promote them opting for repeat procedures.

Intentional Untreated nearsightedness/farsightedness

Few people who receive their initial refractive correction choose not to go all-out with sharp distance visual acuity correction. Remaining slightly myopic increases depth-of-field so that they’re more easily able both close-up reading conditions and distant things at once thus retaining excessive farsightedness enables clearer reading sight as well.

Changes in Prescription

Prescriptions may sometimes drastically change after the laser procedure, resulting in falling out of your prescribed correction range. As a result, you might need another LASIK operation to correct it and bring it back to normal.


In certain cases, patients experience post-operative regression which means there is an unintentional shift in visual acuity that occurs following surgery where vision creeps closer to its originally preoperative prescription.

Now that we’ve identified why someone would choose to undergo another round of Lasik, let’s discuss whether or not it’s advisable.

Can Your Eyes be Reshaped Again?

The short answer is – Yes! It’s totally feasible but only for people whose corneas maintain sufficient thickness after their initial surgical process.

Minimum Corneal Thickness for Safe Procedure:

Above all considerations, minimum cornea thickness must be kept before any additional significant alterations are done.
Roughly 250 microns (µm) should always remain as safe distance at each eye from your necessary eyeglasses or contact lenses prescriptions.No one can really produce more tissue somehow if lasered away than what exists initially on the eye!

So if you opted for “UltraLasik” with a femtosecond auto-focusing excimer laser system first time around performing safely within FDA parameters without any possible degradation induced by mechanical stress then chances are favourable for third/second surgeries provided eligibility holds up.

But, remember: Not every individual is eligible or advised to repeat this refractive operation.

### Who May Opt Out of Repeat Surgery?

A few reasons could keep some individuals from undergoing repeating procedures such as :

  • Thinning eyes with serious concern about their condition won’t meet expectations regarding distances between successive flaps.
  • Medical conditions – No matter how much research goes into researching LASIK operations’ success rates especially when other medical factors play roles besides age; certain health concerns may exclude you from these operations altogether.
  • Eyesight stability – Since LASIK procedures don’t stop poor eyesight as we age, repeat surgeries may be unnecessary since your condition could worsen again in time.
  • Dry eye disease management issues postoperatively


In summary, Laser Eye Surgery can certainly be done twice if the cornea maintains thickness and eligibility criteria is fulfilled. But it’s critical to evaluate your specific circumstancesand unique medical history with a reputable eye surgeon who will test suitability for enduring flap (laser remaining under surface freely after just the first cut)

So go ahead and book yourself an appointment! Your vision might soon remain crystal clear thanks to state-of-the-art laser technology.
