Wavefront Aberrometry & Higher-Order Aberration (HOA) Testing

What Is Wavefront Aberrometry?

Wavefront Aberrometry measures how light travels through the entire optical system of the eye, detecting not just refractive errors but also higher-order aberrations (HOAs) — subtle visual distortions that glasses don’t correct. These include issues like glare, halos, starbursts, ghosting, and decreased contrast vision, which are common in keratoconus.

HOA testing captures an optical “fingerprint” of your eye, revealing distortions that standard prescriptions cannot correct.

Why HOA Testing Is Critical

Higher-order aberrations directly affect visual quality, especially in irregular corneas like those seen in keratoconus. Standard eye exams measure sphere and cylinder only, but HOA testing helps our specialists:

  • Quantify visual distortions uncorrected by glasses

  • Guide customized lens designs using wavefront data

  • Improve contrast and clarity beyond standard prescription limits

  • Assess outcomes objectively after lens fitting

How Aberrometry Works

The test sends a safe light wave into the eye and measures deviations as the wave returns. This creates a detailed 3D map of optical distortions, which our doctors use to design wavefront-optimized and HOA-correcting lenses for superior vision.

Who Benefits Most from HOA Testing

  • Patients with glare, halos, or ghosting

  • Individuals not fully corrected with standard lenses

  • Those seeking custom wavefront scleral or impression-based lenses

Even after multiple eye surgeries, including - among others - LASIK, PRK, cataract, and follow-up laser surgery, I have a very specific vision problem for which I went to multiple ophthalmologists. Dr. Azman was the one who correctly diagnosed my problem. He also designed a scleral lens for my condition. He and his outstanding staff were infinitely patient with me. They answered all of my smart AND dumb questions, and instructed me carefully and thoroughly how to insert, remove, and care for my specialized lens. I was able to see almost perfectly with my new lens right away. To anyone whose vision issues take you to Dr. Azman’s office I think you will find everyone there to be the utmost professionals. I recommend Dr. Azman and his staff wholeheartedly.

I am super excited to have met Dr. Azman and his team. I have been searching for a long time to get the perfect vision that Dr. Azman and his team has given me. I went to my closest eye doctor and all they wanted was my money. But I decided to take a chance and drive 1hr 45mins (one way), to meet and be treated by Dr. Azman and his team…and let me just say, I have 2 bionic eyes (sclera lens). I’m seeing THE BEST I’ve ever seen!!! So let me make a suggestion to you if you have any kind of cornea issues…go see Dr. Azman and I promise you, he will get you and your vision right!!! Thank you Dr. Azman, you are THE BEST💕

Dr. Azman is amazing! From my first phone contact with Azman Eye Care Specialists I knew this was a good place. I was able to speak with Dr. Azman directly and he listened and understood my special needs and personally scheduled an appointment for me. I was impressed with his office; it is clean and comfortable and the staff were helpful and courteous. Dr. Azman evaluated my eyes and said he could meet my complex needs. His expertise and equipment are beyond what I expected or have ever seen in my 50+ years of wearing contacts. This is the place to go for specialty lenses.

I feel incredibly lucky to have found Dr. Benjamin Azman. He took excellent care of my right eye and recommended a scleral lens that works perfectly—honestly, it’s now even better than my left eye. My vision has improved so much, and the difference has been life-changing for me. Dr. Azman is knowledgeable, patient, and truly cares about his patients’ outcomes. I’m very grateful for his treatment and expertise, and I highly recommend him to anyone dealing with complex vision issues.

This is hands down the most kind and caring doctors office I’ve ever been to. Dr. Azman was very knowledgeable and was determined to solve my blurry vision issue that other docs kept brushing off. They also got me an appointment very quickly as well. Highly recommended!!

Azman Eye Care took me on as a client and has done a great job of making me feel at home! Dr Azman offered a new type custom sclerl lens for my eyes, while this was above my insurance, this has been hands down one of the best purchases I have had for my eyes. Thanks to Dr Azman I can now comfortably be in my contacts longer with less eye irritation. Thank you Azman Eye Care!

After going to the eye doctor and failing all of the test I was diagnosed with Keratoconus in 2016. I guess I couldn’t accept the diagnosis, I didn’t want to wear contacts so I didn’t. At that time the Keratoconus hadn’t advanced. I went to a prominent eye doctor and I was able to get prescription glasses for many years. I looked at it like this, I spent most of my life trying to keep things out of my eyes why would I make things more complicated just get glasses you can’t do it, get those contacts in that is. From 2016 until 2021 I was able to get prescription glasses. I went in for my annual eye exam and I didn't do so well, that is when I found out that they could no longer make my prescription. So now my vision is horrible, the sun is my enemy and I can’t get any more glasses. Did I mention that I walked around squinting for 4 years!! Yess stupid and dangerous making all types of mistakes! I couldn’t take it anymore I am scanning the internet on what I can do where I can go, I can’t see!! The only place that I found in the DMV that specializes in Keratoconus was Azman Eye Care so I called Dr. Azman back,( reluctantly) I felt embarrassed & ashamed that I basically wasted those super expensive contact lenses that I had before & disappeared, now I needed to get them again. Dr. Azman & his staff AMAZING!! Welcomed me back like I had never left. Please keep in mind 4 years I went through hell at home, work on the road, everywhere!! Guys it’s been a journey! I can’t even tell you all the near accidents! My poor husband won’t let me drive anywhere!!! So I finally came in for an appointment 2025. Dr. Azman put these temporary lens on me and told me this is what my vision will look like, I broke down like a person that was blind and now I have sight!! I am serious a whole new world!! I didn’t think it was possible! My God!! I can see!! 20/20 yayyyy!! Joanne bless her🙏🏾 I would not have been able to do this without her! I have spent almost 60 years of my life keeping stuff out of my eyes so this gave me stress & anxiety! Joanne worked with me she is so patient, encouraging all of it!! ( I love her) The same exact way she was in 2016 she hasn’t changed a bit none of them!! If you have Keratoconus Azman Eye Care Specialist is the only place to go!!! I promise you You will see again🩷
