Higher-order aberration (HOA)- corrected scleral lenses represent a cutting-edge advancement in optometry, offering patients a tailored solution for vision correction. Unlike traditional contact lenses, HOA-corrected scleral lenses address common refractive errors like myopia or astigmatism and tackle more nuanced visual imperfections known as higher-order aberrations. These aberrations can cause visual distortions such as glare, halos, and poor contrast sensitivity.
Higher Order Aberration (HOA) Scleral Lenses
Experience sharper, high-definition vision without glare, halos, or blurriness.
WHAT ARE HOA CORRECTED SCLERAL LENSES?
- Precision-Corrected Vision: Custom-designed to counteract unique higher-order aberrations.
- Enhanced Night Vision: Reduces glare and halos for clearer sight in low-light conditions.
- Superior Comfort: Large-diameter design provides stability and all-day moisture retention.
- Ideal for Complex Cases: Beneficial for patients with keratoconus, post-surgical complications, or corneal irregularities.
How HOA Scleral Lenses Work
HOA-corrected scleral lenses are designed using highly detailed measurements of your eye’s optical imperfections. The process begins with an advanced wavefront aberrometer, which maps the unique higher-order aberrations present in each eye. This data is then used to create a fully customized scleral lens that corrects these irregularities while offering superior clarity and comfort.
Patients can expect a tailored fitting process to ensure the best possible vision, followed by a brief adaptation period as their eyes adjust to the lenses.
Who Can Benefit from HOA Scleral Lenses?
These lenses are ideal for patients who experience visual distortions that go beyond traditional refractive errors. You may be a candidate if you have:
- Keratoconus or corneal scarring
- Post-LASIK or RK visual distortions
- Night vision difficulties due to glare or halos
- Irregular corneal surfaces or previous surgical complications
If standard contact lenses haven’t provided the clarity you need, HOA scleral lenses could be the solution.
Why Choose HOA Scleral Lenses?
With HOA-corrected scleral lenses, patients can expect a dramatic improvement in vision quality. These lenses offer:
- Crisper, high-definition vision tailored to your eye’s unique optical map.
- Greater comfort and stability compared to standard gas-permeable lenses.
- Reduced light sensitivity and contrast issues for a more natural visual experience.
- A fully customized fit that adapts to even the most complex eye conditions.

Frequently Asked Questions
How are HOA scleral lenses different from regular scleral lenses?
While both lenses are designed to vault over the cornea and provide superior comfort, HOA scleral lenses go further by correcting higher-order aberrations (HOAs). These advanced lenses use precise wavefront technology to address visual distortions like glare, halos, and double vision that standard scleral lenses may not entirely correct.
Who can benefit the most from HOA scleral lenses?
HOA scleral lenses are ideal for patients with complex vision problems, including:
- Keratoconus or corneal scarring
- Post-LASIK, RK, or PRK complications
- Severe night vision disturbances (glare, halos, starbursts)
- Irregular corneas or higher-order visual distortions
If traditional contact lenses or glasses haven’t provided clear vision, HOA scleral lenses may be the right solution.
How are HOA scleral lenses fitted?
Fitting HOA scleral lenses requires specialized diagnostic equipment. The process includes:
- Wavefront aberrometry to map the unique optical distortions in each eye.
- Custom lens design based on the patient’s specific HOA profile.
- Trial fittings and adjustments to ensure optimal comfort and visual clarity.
The fitting process may take a few visits to achieve the best results.
Are HOA scleral lenses comfortable to wear?
Yes! Scleral lenses are known for their exceptional comfort because they rest on the sclera (the white part of the eye) rather than the sensitive cornea. The fluid-filled reservoir between the lens and the cornea keeps the eye hydrated and reduces irritation, making them ideal for patients with dry eye syndrome or corneal irregularities.
How long do HOA scleral lenses last, and how do I care for them?
With proper care, HOA scleral lenses can last one to two years before needing replacement. Care instructions include:
- Cleaning and disinfecting them daily with a prescribed scleral lens solution.
- Filling the lens with preservative-free saline before inserting it.
- Using a plunger tool for easy insertion and removal.
A well-maintained lens ensures long-term comfort and optimal vision correction.
