Corneal Topography, also known as corneal mapping, uses advanced imaging technology to measure the surface curvature and contour of the cornea. This test provides detailed data in the form of a color-coded map, which helps ophthalmologists and optometrists analyze the eye’s optical quality and detect subtle abnormalities.

Why It’s Done:

• To detect early signs of keratoconus or other corneal disorders
• To evaluate candidates for LASIK, PRK, or other refractive surgeries
• To monitor progression of corneal diseases over time
• To design and fit specialty contact lenses (RGP, scleral, Ortho-K)
• To assess corneal healing after surgeries or trauma

How It Works:

• The patient places their chin on a rest and looks into the topographer.
• The device captures thousands of data points using reflected light patterns.
• The system generates a topographic map, showing variations in corneal curvature.

What the Map Shows:

• Steep and flat areas of the cornea
• Irregular astigmatism
• Asymmetry or thinning of the cornea
• Indicators of conditions like keratoconus, pellucid marginal degeneration, or ectasia

Benefits:

• Quick, painless, and non-contact test (takes less than a minute)
• Highly accurate and repeatable results
• Helps guide custom treatment plans and lens fittings
• Essential for pre-operative and post-operative evaluation

Who Should Get Corneal Topography:

• Individuals with blurred or distorted vision not correctable by glasses
• Patients with progressive vision changes or known corneal conditions
• Candidates for laser vision correction
• Contact lens wearers experiencing discomfort or vision issues

Our clinic uses high-resolution, state-of-the-art corneal topographers to ensure precise diagnostics and optimal treatment outcomes. The results are interpreted by trained specialists to assist in accurate diagnosis and personalized eye care planning.
