What Is Corneal Topography and When Does Your Practice Need It?

What Is Corneal Topography and When Does Your Practice Need It?

Corneal topography is a diagnostic imaging technique that creates a detailed map of the corneal surface. By measuring thousands of points across the cornea, topography systems produce color-coded maps that reveal the shape, curvature, and elevation of the corneal surface in high detail.

At Blue River Medical, we represent Eaglet Eye, whose Eye Surface Profiler is an advanced corneal topography and anterior segment imaging system. Here is what practices need to know about corneal topography and when it makes sense for your workflow.

How Corneal Topography Works

Corneal topography systems project a pattern of light onto the corneal surface and analyze the reflection to calculate curvature and elevation across the entire cornea. The resulting maps display data in color-coded formats that make it easy to identify irregularities, asymmetries, and pathology.

Modern systems like the Eaglet Eye Surface Profiler use advanced imaging algorithms to capture both the anterior and posterior corneal surfaces, providing comprehensive anterior segment data.

Clinical Applications of Corneal Topography

Contact Lens Fitting

Corneal topography is invaluable for specialty contact lens fitting, including:

• Scleral lenses — topography data is essential for designing and fitting large-diameter scleral lenses
• Orthokeratology (Ortho-K) — topography guides fitting and monitors corneal reshaping progress
• Custom soft lenses — topography supports fitting for patients with irregular corneas
• RGP lenses — detailed curvature data improves fitting accuracy and patient comfort

Keratoconus Detection and Monitoring

Keratoconus causes progressive thinning and steepening of the cornea. Topography is one of the primary tools for:

• Early detection of keratoconus before it is visible on slit lamp examination
• Monitoring progression over time
• Screening candidates for refractive surgery

Refractive Surgery Screening and Planning

All refractive surgery candidates should undergo corneal topography to:

• Rule out keratoconus and other contraindications
• Plan ablation profiles for LASIK and PRK
• Document pre-operative corneal shape for post-operative comparison

Dry Eye and Ocular Surface Assessment

Advanced topography systems can also assess the tear film and ocular surface, supporting dry eye evaluation alongside other diagnostic tools.

The Eaglet Eye Surface Profiler

The Eaglet Eye Surface Profiler is an advanced anterior segment imaging system that goes beyond standard corneal topography. It captures high-resolution data across the entire anterior segment including the cornea, limbus, and sclera — making it particularly valuable for scleral lens fitting and complex anterior segment cases.

Key capabilities of the Eaglet Eye Surface Profiler:

• High-resolution corneal topography
• Scleral topography for scleral lens fitting
• Anterior segment imaging
• Compatible with leading scleral lens fitting software

When Does Your Practice Need Corneal Topography?

Consider adding corneal topography if your practice:

• Fits specialty contact lenses including sclerals, Ortho-K, or RGPs
• Sees patients with keratoconus or irregular corneas
• Co-manages refractive surgery patients
• Wants to expand specialty contact lens services
• Has patients with complex dry eye and ocular surface disease
