What is wavefront lasik?
Wavefront LASIK is a type of laser eye surgery that uses a wavefront sensor to measure irregularities in the cornea, the clear outer layer of the eye. This information is then used to create a customized treatment plan that corrects these irregularities and improves vision.
Wavefront LASIK is more precise than traditional LASIK surgery, which uses a general treatment plan for all patients. This precision allows wavefront LASIK to correct a wider range of vision problems, including higher-order aberrations such as coma, trefoil, and spherical aberration.
Wavefront LASIK is also less likely to cause side effects such as glare and halos, which can occur with traditional LASIK surgery. This is because wavefront LASIK uses a more precise treatment plan that is tailored to each individual patient's eye.
How does wavefront LASIK work?
1. The patient's cornea is mapped using a wavefront sensor. This sensor measures the irregularities in the cornea and creates a detailed map of its surface.
2. The treatment plan is created based on the wavefront map. This plan specifies the exact amount of tissue that needs to be removed from the cornea to correct the irregularities.
3. The laser is used to remove the tissue according to the treatment plan. This is done with extreme precision, using a beam of light that is only a few microns wide.
4. The cornea heals over the next few days, and the patient's vision improves.
What are the benefits of wavefront LASIK?
* More precise than traditional LASIK surgery. This allows wavefront LASIK to correct a wider range of vision problems, including higher-order aberrations.
* Less likely to cause side effects such as glare and halos. This is because wavefront LASIK uses a more precise treatment plan that is tailored to each individual patient's eye.
* Faster recovery time than traditional LASIK surgery. This is because wavefront LASIK uses a less invasive technique to remove the tissue from the cornea.
* Excellent long-term results. Wavefront LASIK has been shown to provide excellent long-term results, with most patients achieving 20/20 vision or better.
Who is a good candidate for wavefront LASIK?
Wavefront LASIK is a good option for most people who are considering LASIK surgery. However, there are some exceptions, such as people with:
* Thin corneas. Wavefront LASIK may not be suitable for people with thin corneas, as there may not be enough tissue to safely remove.
* Certain eye diseases. Wavefront LASIK may not be suitable for people with certain eye diseases, such as glaucoma or cataracts.
* Unstable vision. Wavefront LASIK may not be suitable for people whose vision is still changing, as the surgery may not be able to provide long-term results.
If you are considering wavefront LASIK surgery, it is important to talk to your doctor to see if you are a good candidate.
