Can my eyesight get worse after LASIK?

Hi, it’s Dr. Chotiner from Memorial Eye Institute. When I tell people I’m a LASIK surgeon, some of them ask me: “Can my eyesight get worse after LASIK?”

A successful LASIK procedure is determined largely by whether you meet certain patient criteria and if laser eye surgery is right for you.

While the vast majority of LASIK surgery results are excellent, you should be fully aware of the possible side effects, risks, and potential LASIK complications before you choose to undergo the procedure.

Here are examples of risks and potential complications that can occur during surgery:

  • Under-correction or over-correction
    This is more common with higher prescriptions and can be mitigated by planned 2-stage treatments; correctable with an enhancement.
  • Corneal flap complications
    This is rare in expert hands (1 in 1000). This can be mitigated by expert use of equipment; correctable with an enhancement.
  • Debris under the corneal flap
    This is rare in expert hands and will likely not affect the visual results. It can be mitigated by stringent adherence to superior safety protocols; correctable with an enhancement.
  • Diffuse Lamellar Keratitis
    This is also rare in expert hands (1 in 500). It can be mitigated by stringent adherence to superior safety protocols; correctable with an enhancement.
  • Vascular occlusion
    Extremely rare; 1 in 1 million will experience this.
