Keratoconus is an eye condition that affects the cornea, gradually altering its shape and leading to distorted vision. Because it progresses over time, early detection is crucial in preventing severe vision impairment. Many people don’t realize that a comprehensive eye exam can help identify keratoconus in its earliest stages. Understanding how your eye doctor screens for this condition and what treatment options are available can help you take control of your eye health.

What Is Keratoconus?

Keratoconus occurs when the cornea—the clear, dome-shaped front surface of the eye—becomes thinner and begins to bulge into a cone shape. This irregular curvature can cause blurred and distorted vision, increased light sensitivity, and difficulty seeing at night. While the exact cause is unknown, genetic and environmental factors, including frequent eye rubbing and allergies, may contribute to its development.

How Do Eye Doctors Screen for Keratoconus?

Detecting keratoconus early is key to managing the condition effectively. Eye doctors use several advanced diagnostic techniques to screen for keratoconus, including:
 

• Corneal Topography – This imaging test maps the surface of the cornea, detecting even subtle changes in its shape and curvature.
   

• Pachymetry – This test measures corneal thickness, as keratoconus is often associated with corneal thinning.
   

• Slit-Lamp Examination – A detailed examination using a microscope allows the doctor to identify signs of corneal irregularities.
   

• Keratometry – This measures the curvature of the cornea to identify abnormal steepening.

If early signs of keratoconus are detected, your eye doctor may recommend further testing or refer you to a specialist for additional evaluation.

Specialty Contact Lens Options for Keratoconus

Specialty contact lenses are a highly effective option for managing keratoconus, providing improved vision and comfort compared to traditional soft lenses. Scleral lenses are a popular choice, as they vault over the irregular cornea and rest on the sclera, creating a smooth optical surface while keeping the eye hydrated. Rigid gas permeable (RGP) lenses also offer crisp vision by masking corneal irregularities, though they may take time to adjust to. By working with a doctor, patients with keratoconus can find the best specialty lens option to suit their vision needs and lifestyle.
