Higher vs. Lower Order Aberrations

Higher vs. Lower Order AberrationsIf you want to have the clearest vision without the aid of corrective lenses, it’s important that you visit our Oklahoma City LASIK center. By meeting with our team, we will be able to assess your situation and determine if refractive surgery will be best for you and your needs.

When it comes to improving your vision, however, we will want to address both lower order aberrations and higher order aberrations. You may not have heard these terms before, so let’s go over both so you understand why these are important matters to consider when it comes to vision correction.

About Refractive Errors – Lower Order Aberrations

The most common vision problems that are treated at our practice are known as lower order aberrations. These are related to imperfections in the cornea. You may know lower order aberrations better by the term refractive errors, or the following common names for refractive errors:

  • Nearsightedness/Myopia: This is the ability to see nearby objects clearly but difficulty seeing objects that are far away.

  • Farsightedness/Hyperopia: This is the ability to see far away objects clearly but difficulty seeing objects that are nearby.

  • Astigmatism: This is a common blurriness of vision that often accompanies nearsightedness or farsightedness.

During your visit to our practice, an eye doctor serving Oklahoma City will let you know what vision problem you suffer from and determine the best treatment from there.

What are higher order aberrations?

Higher order aberrations are also related to imperfections in the shape of the cornea. These types of vision problems tend to be more minute vision imperfections that are nonetheless noteworthy, such as:

  • Poor night vision

  • Halos

  • Glare

  • Starbursts

  • Poor color sensitivity

  • Ghost images

Can LASIK surgery treat higher order aberrations?

In the past, LASIK could only address lower order aberrations with any level of effectiveness. Today, thanks to custom LASIK surgery technology, both lower order aberrations and higher order aberrations can be treated.

Why is custom LASIK surgery so effective?

Custom LASIK technology takes an extremely detailed digital map of the corneal surface. This three-dimensional digital map pinpoints the minute imperfections in the cornea that cause higher order aberrations. The information is fed into a computer that then guides the LASIK laser during the surgical procedure.

What Custom LASIK Means for Patients

Custom LASIK surgery means that patients can experience the clearest vision possible. Not only will they have lower order aberrations corrected, but they will have markedly better eyesight after custom LASIK surgery than they would after traditional LASIK surgery.

More Advances in LASIK Surgery Technology

In addition to advances in extremely accurate custom LASIK technology, we are also able to perform extremely safe LASIK without the need for any physical tools. This Oklahoma City bladeless LASIK is performed entirely with lasers, making for the safest LASIK procedure possible.
