Custom LASIK for Higher and Lower Order AberrationsVision problems come in many different forms, and thankfully there are plenty of eye care treatments than can address whatever issue you're facing. When you visit our Bakersfield laser eye surgery centers, we will perform a comprehensive eye examination to identify the vision problem that you are facing and then effectively treat it.

Two vision problems that we see a lot at our practice are lower order aberrations and higher order aberrations. You may not be too familiar with those terms, but you probably know what both of these are. We'd like to take a few minutes right now to go over the basics of both.

About Lower Order Aberrations

Lower order aberrations is just another term that our LASIK surgeons in Bakersfield use to refer to refractive errors. These vision issues you probably know better by the following names:

  • Myopia (Nearsightedness) - Myopia refers to cases in which people can see nearby objects clearly but distant objects appear blurry. It's caused by light focusing short of the retina.

  • Hyperopia (Farsightedness) - Hyperopia refers to cases in which people can see distant objects clearly but nearby objects appear blurry. It's caused by light focusing behind the retina.

  • Astigmatism - Astigmatism refers to a general blurring of the vision caused by irregular curvature of the cornea or the lens. This often accompanies myopia and hyperopia.

Treating Lower Order Aberrations

There are many different options for treating lower order aberrations. One of the most popular options today is Bakersfield LASIK. LASIK uses safe laser technology to carefully reshape the cornea, allowing people to see clearly without the aid of corrective lenses such as prescription glasses and contacts.

About Higher Order Aberrations

Higher order aberrations refer to finer flaws of the cornea that result in the following visual flaws:

  • Halos
  • Glare
  • Starbursts
  • Double vision
  • Poor night vision

Treating Higher Order Aberrations

The only way to treat higher order aberrations involves advanced custom LASIK technology. Custom LASIK will use digital mapping scanners that pinpoint very minute imperfections in the cornea. Once these have been identified, the higher order aberrations can be treated during a computer-guided LASIK procedure.

Can higher and lower order aberrations be treated at the same time?

Yes. Custom LASIK surgery will address both higher order aberrations as well as lower order aberrations, meaning excellent vision results for patients that exceed that of traditional LASIK surgery. When you visit our LASIK surgeons and eye doctors in Bakersfield, we'll determine if custom LASIK is the best bet for you.

Weigh All of Your Treatment Options

Not everyone is a good candidate for LASIK surgery. Issues with dry eye, corneal thinness, and other factors may mean that another refractive surgery option is more ideal, or that surgery needs to be avoided altogether.

During your consultation, we'll be sure to go over all of your options for advanced vision correction, whether it involves surgical treatment or tried and true corrective lenses. We want to make sure that you vision is the very best that it can be.
