Yes — LASIK can be performed more than once, and this is called LASIK enhancement surgery. Here is everything you need to know about getting laser eye surgery a second time.
What Is LASIK Enhancement?
LASIK enhancement is a second laser procedure to fine-tune your vision if the initial correction was not quite perfect or if the prescription has shifted over time. This typically involves lifting the original corneal flap and applying additional laser treatment.
Who Needs LASIK Enhancement?
- Patients with residual prescription after primary LASIK (under-correction or over-correction)
- Patients experiencing gradual prescription regression
- Patients who had LASIK 10+ years ago and whose eyes have changed with age
How Common Is LASIK Enhancement?
With modern AI laser technology, the need for enhancement is quite low — approximately 2–5% of patients require a touch-up. At Centre For Lasik, we offer a 1-year enhancement guarantee — if your vision doesn’t meet expectations within the first year, enhancement is included at no additional cost.
Eligibility for Enhancement
The main limiting factor is residual corneal thickness. A minimum residual stromal bed of 250 microns must be maintained for safety. If sufficient tissue is available, enhancement can typically be performed safely.
