We mentioned before that there have been many positive advances in eye care treatment, particularly in regards to LASIK technology. Indeed, the LASIK that's performed today is superior to the LASIK of yesteryear (which, again, was already quite effective).
One of the biggest changes in LASIK technology is the advent of custom LASIK using wavefront mapping technology. While all LASIK has been custom LASIK, this new technology has changed the quality of care that a LASIK surgeon can provide. Let's look into this issue in a little more detail right now.
About LASIK Surgery
First some of the basics. LASIK surgery is a refractive procedure that is performed in order to reshape the cornea and improve the focus of light on the retina, the light-sensitive tissue at the back of the eyes. By reshaping the cornea, LASIK can effectively treat myopia (nearsightedness), hyperopia (farsightedness), and astigmatism.
Wavefront technology allows LASIK surgeons to create a precise digital map of the surface of the cornea. This data is fed into a computer in order to guide the LASIK laser during the actual surgery. This is crucial because wavefront mapping can pinpoint the most minute imperfections in the corneal surface, allowing your surgeon to address both lower order aberrations as well as higher order aberrations.
Lower and Higher Order Aberrations
Lower and higher order aberrations refer to different kinds of corneal defects that result in vision issues. By addressing these aberrations, laser vision correction specialists allow patients to see clearly without the aid of corrective lenses.
Lower order aberrations refers to corneal contour issues that cause the following:
- Myopia (Nearsightedness)
- Hyperopia (Farsightedness)
Higher order aberrations refer to minute imperfections on the corneal surface that cause the following:
- Poor night vision
- Poor contrast sensitivity
- Double vision
What Traditional LASIK Surgery Can Treat
Traditional LASIK surgery that did not use wavefront mapping was only able to treat lower order aberrations. Higher order aberrations could not be treated with any regularity using traditional LASIK.
What Wavefront Custom LASIK Surgery Can Treat
Wavefront custom LASIK is able to treat both lower order aberrations as well as higher order aberrations.
How Custom LASIK Benefits Patients
There are a number of patients benefits from undergoing custom LASIK. For one, the vision quality experienced after undergoing LASIK is exceptional. Patients are able to see clearly and experience fewer issues with higher order aberrations in the long run. The overall quality of the vision is much clearer and better overall.
Custom LASIK also means greater safety and less chance of human error. Since the digital map is fed into a computer which guides the LASIK laser during surgery, there is less chance of human error or surgical error taking place.
Overall, custom wavefront LASIK helps patients achieve the best possible LASIK results today.
