Custom LASIK surgery is safe and effective, though it isn't always the best option for everyone. With that in mind, let's go over the basics of LASIK and then consider why corneal thickness matters with regard to candidacy.

How LASIK Surgery Is Performed

LASIK is a refractive surgery procedure that uses precise laser pulses and digital mapping technology to alter the shape of a person's cornea. By doing this, light passes through a person's eyes and focuses properly on the retinas, which is the light sensitive tissue located at the back of the eyes.

LASIK is an ideal treatment option for refractive errors, which you may know better by the following names:

  • Myopia (nearsightedness)
  • Hyperopia (farsightedness)
  • Astigmatism

Why Corneal Thickness Matters

During LASIK surgery, a small flap is created in the topmost layer of the cornea. This top layer is known as the epithelium. The flap is lifted up so the cornea can be properly contoured and revised, and then set down to heal. People who have regular corneal thickness will face no issues when it comes to undergoing LASIK surgery. So long as they are good candidates and not pregnant or nursing, LASIK can be performed without any problems.

What About LASIK for Patients with Thin Corneas?

Patients with thin corneas may face some roadblocks when it comes to LASIK surgery. When corneas are thin, a traditional corneal flap cannot be created. In the vast majority of cases, patients who have thin corneal thickness or other issues with the shape or size of their corneas will not be able to undergo LASIK. Even if a patient is a good candidate otherwise, LASIK simply will not be recommended.

Alternatives to LASIK Surgery

Thankfully there are alternatives to LASIK for people who have thin corneas. The most common alternatives are PRK, LASEK, and Epi-LASIK. These are also refractive surgery procedures and are quite similar to LASIK, though there are no corneal flaps created. The post-surgical recovery may take a little more time than LASIK, but these procedures can achieve similar results that are just as satisfying and effective.
