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
