Corneal Topography
Detailed Corneal Mapping with Pentacam AXL Imaging
What Is Corneal Topography?
Corneal topography creates a detailed map of the front surface of your eye—the cornea. Instead of relying on a few prescription numbers alone, topography shows the shape, curvature, and subtle irregularities that can affect clarity, comfort, and long-term eye health.
At Specs Appeal, we use advanced corneal mapping to support earlier diagnosis, more precise specialty lens fittings, and careful monitoring when eyes are changing over time.
Pentacam AXL Imaging
We utilize the Pentacam AXL, an advanced corneal imaging system that creates detailed three-dimensional maps of the cornea and measures axial length. This combination gives us a more complete picture of both corneal shape and eye growth—information that matters for keratoconus screening, scleral lens design, and myopia management.
With exceptional precision, Pentacam AXL imaging helps us detect concerns earlier, fit specialty lenses more accurately, and track meaningful changes that a standard eye exam may miss.
3D Mapping
Detailed corneal maps reveal shape and irregularities standard exams can miss.
Earlier Detection
Supports earlier identification of keratoconus and progressive corneal changes.
Axial Length
Measures eye growth to guide personalized myopia management plans.
Keratoconus Detection
Keratoconus causes the cornea to thin and bulge into an irregular cone shape, which can lead to blurred or distorted vision that glasses alone may not fully correct. Corneal topography is one of the most important tools for detecting early keratoconus and monitoring progression.
By mapping elevation and curvature across the cornea, we can identify suspicious patterns sooner, recommend the right specialty contact lens options, and coordinate care that protects vision over time.
More Precise Scleral Lens Fittings
Scleral lenses vault over the cornea and rest on the white of the eye, creating a smooth optical surface for patients with irregular corneas, keratoconus, dry eye, or hard-to-fit eyes. Accurate corneal mapping is essential for designing lenses that fit comfortably and deliver clear vision.
Pentacam imaging helps us evaluate corneal contour and related measurements so your scleral lenses can be customized for clarity, comfort, and long-term success—not a one-size-fits-all approach.
Myopia Monitoring & Axial Length
Managing childhood myopia requires more than updating a glasses prescription each year. Axial length measurement helps us track how the eye is growing over time—the key factor linked to myopia progression and future eye health risk.
Combined with corneal imaging and proven treatments such as Stellest® lenses, Ortho-K, or other myopia management options, Pentacam AXL data allows us to create personalized plans and monitor whether treatment is working.

Who Benefits from Corneal Topography?
Corneal topography and Pentacam AXL imaging can be especially helpful if you or your child:
Have progressive nearsightedness or need myopia monitoring
Have been told you may have keratoconus or irregular astigmatism
Need specialty or scleral contact lenses
Have reduced vision that glasses do not fully correct
Are being evaluated for Ortho-K or complex contact lens designs
Need careful monitoring of corneal or eye-growth changes over time
Schedule Corneal Imaging
If you need specialty lens care, keratoconus evaluation, or advanced myopia monitoring, corneal topography and Pentacam AXL imaging help us see more—and care more precisely.
