Wave Front Guided HOA Corrected Scleral Lenses

At the Khanna Vision Institute, we are proud to offer our patients the latest advancements in scleral lens technology. Our wave front guided, higher-order aberration (HOA) corrected scleral lenses are revolutionizing the way we treat keratoconus and other corneal irregularities. Scleral lenses have long been recognized as an effective solution for patients with keratoconus, providing unparalleled visual acuity and comfort. However, our wave front guided scleral lenses take this technology to the next level. By precisely mapping the unique contours of each patient’s eye, we can create a customized lens that not only corrects refractive errors, but also neutralizes higher-order aberrations that traditional lenses often struggle with.

Wavefront-Guided HOA Corrected Scleral Lenses

How it Works

Wavefront Technology: This technology measures how light waves travel through the eye. In eyes with keratoconus, these light waves are often distorted due to the irregular shape of the cornea. Wavefront aberrometry creates a detailed map of these distortions, identifying both lower-order aberrations (like nearsightedness and astigmatism) and higher-order aberrations (HOAs).

Customized Lens Design: Using the wavefront data, scleral lenses are custom-designed to correct the specific aberrations of the individual eye. This customization allows for the precise correction of the optical imperfections caused by keratoconus.

Large Diameter Lenses: Like other scleral lenses, wavefront-guided HOA corrected scleral lenses rest on the sclera and vault over the cornea, creating a tear-filled reservoir between the lens and the cornea. This not only improves vision by smoothing out corneal irregularities but also enhances comfort.


Superior Vision Correction: By specifically targeting and correcting HOAs, these lenses provide clearer and sharper vision compared to conventional lenses or glasses.

Enhanced Comfort: The larger size and custom fit of scleral lenses reduce the movement of the lens on the eye, leading to increased comfort, especially for individuals with highly irregular corneas.

Hydration and Protection: The fluid reservoir beneath the lens keeps the cornea hydrated and protected, which can be particularly beneficial for patients experiencing dry eye symptoms.

Fitting Process

Initial Evaluation: An eye care professional assesses the patient’s suitability for wavefront-guided HOA corrected scleral lenses. This includes a comprehensive eye exam and corneal topography to map the surface of the cornea.

Wavefront Aberrometry: A detailed wavefront analysis is conducted to measure the specific aberrations of the eye. This data is crucial for designing the customized lenses.

Lens Design and Fabrication: Based on the wavefront data and corneal topography, the lenses are custom-designed and manufactured. This process ensures that the lenses are tailored to correct the precise optical imperfections of the patient’s eyes.

Lens Fitting: The patient is fitted with the custom lenses. During this appointment, the eye care professional may make adjustments to ensure optimal fit and vision correction.

Follow-Up Care: Regular follow-up visits are necessary to monitor the fit of the lenses, make any needed adjustments, and ensure the ongoing health of the eyes.


Cost: These custom lenses can be expensive due to the advanced technology and detailed customization involved.

Adaptation Period: Patients may need time to adjust to the feel of the larger lenses.

Maintenance: Proper care and cleaning of the lenses are essential to maintain eye health and prolong the lifespan of the lenses.
