High Order Aberrations

In an ideal world, everyone would have perfectly-shaped eyes. The reality, however, is that practically every eye has some form of aberration somewhere in it. These aberrations may or may not cause vision problems, but don't be too surprised if your eye doctor informs you that you are having difficulties due to some such imperfection. In addition to relatively straightforward vision problems such as nearsightedness and farsightedness, it is also possible to suffer higher order aberrations that distort images in a much more complex manner.

What Is an Aberration?

Any deviation from normal refraction of incoming light waves can be considered an aberration, even if that aberration is so minor that it causes no vision problems whatsoever. Any change in the shape, consistency, or functionality of any part of the eye can distort the way light is focused and turned into images by the eye. Nearsightedness and farsightedness involve a simple distortion of the eyeball's shape, while astigmatism usually involves a fairly simple distortion of the cornea. These conditions are thus easy to diagnose and correct.

Causes

Higher order aberrations can be caused by a number of factors. The thickened proteins that create cataracts, for instance, can interfere with proper refraction, as can a lack of tear film in people with chronically dry eyes. Corneal scarring from disease or injury, and irregularities in the lens or vitreous humor (the gelatinous substance inside the eye), can also cause higher order aberrations. These little imperfections in the eye can bend and shift the waveforms of incoming light in all sorts of ways. Eye doctors have learned to recognize these different types of distortion, assigning them such names as trefoil, quadrafoil, coma, defocus, and spherical aberration.

Treatment

Treatment for a higher order aberration involves either correcting the underlying cause, or compensating for the resulting vision problem. If your higher order aberration is the result of cataracts or dry eyes, for instance, your eye care professional can recommend treatments for these disorders that to dramatically improve your vision. The fitting of intraocular lens can resolve not only cataracts but other lens disorders as well.

If your eye's vitreous humor is contributing to the problem, vitrectomy or other procedures can address that issue. You may find that prescription eyewear or refractive laser surgeries such as LASIK can correct your vision adequately. Talk to your eye care professional about which treatments can help your higher order aberrations.

Reviews From Our Satisfied Patients

  • "We use Anderson Optometry for all of our family’s vision needs. Recently, we had to have our youngest fitted for new glasses and he made the experience fun for her and informative for us. We know Dr. Anderson will always take good care of our family’s eye care and that’s why we wouldn’t go to anywhere else."
    The Harrison Family
  • "Dr. Anderson and his staff are so patient and friendly. Dr. Anderson prescribed me glasses and I had the toughest time picking out frames. They didn’t rush, but instead made helpful suggestions and now I have an awesome pair of frames, not to mention the fact that I can see ten times better than before. You guys are the best!"

  • "I’ve been going to Dr. Anderson for over five years now and even though I only see him once a year for my annual exam, he and his staff always make me feel very welcome and take care of all my eye care needs. Anderson Optometry is the best at what they do and make you feel right at home."
    Anthony
  • "I was having headaches and felt my contacts were easily drying out all the time. I went in to see Dr. Anderson and after an evaluation, he suggested a switch in the type of lenses I use. Within a week of using the new lenses, I noticed a change and haven’t had any problems since. Thanks, Dr. Anderson!"
    Matt
  • "I had considered Lasik surgery in the past, but was still hesitant about the process. Dr. Anderson was very thorough in his consultation with me and answered all of my questions, making me feel comfortable with going forward with the procedure. I’m so glad I did the Lasik, it has been of great convenience to me and my sight has never been better"
