Cornea

Expert Cornea Care Starts Here

The cornea is the clear, dome-shaped surface at the front of your eye that helps focus light and protects the inner structures of your eye. Maintaining cornea health is essential for clear vision and comfort.

At Prism Eye Institute, our world-class cornea specialists, advanced technology, and compassionate care team are here to give you peace of mind and the best chance at healthy vision for life.

What to Expect

Your first cornea visit will take about 2–3 hours so we can give your eyes the attention they need.

During your visit:

  • Full eye exam, including pupil dilation if needed
  • Advanced corneal imaging and preliminary tests
  • Consultation with a cornea specialist to review results
  • Discussion of your treatment plan and, if needed, same-day procedures (e.g. minor procedure)
  • We explain every step and answer all questions so you feel comfortable and informed.

Your Cornea Testing, Explained

Before seeing the doctor, our technicians perform quick, painless tests to give a close look at your cornea’s health.

Tests may include:

These tests help your doctor create the most accurate treatment plan.

  • Corneal Topography: Maps the surface shape of your cornea for keratoconus or refractive planning (OHIP/Private depending on test)
  • Pachymetry: Measures corneal thickness for surgical planning or disease monitoring
  • Specular Microscopy: Evaluates corneal endothelial cells for overall cornea health
  • Other Specialized Imaging: Depending on your condition, additional non-OHIP tests may be recommended

Protecting Your Cornea Health

Conditions like keratoconus, corneal dystrophies, infections, and post-surgical scarring can cause permanent vision changes if not treated promptly.

Early detection and treatment are essential. By coming in, you’re taking the most important step to protect your sight.

Coverage & Patient Support Programs

Most cornea consultations and medically necessary treatments are covered by OHIP.

For procedures or non-OHIP tests, our team will help you understand costs and available patient support programs to make care accessible.

Frequently Asked Questions

 Some of the most common include:

  • Dry eye disease
  • Keratoconus (thinning or bulging of the cornea)
  • Corneal dystrophies (inherited conditions)
  • Infections or ulcers
  • Scarring from trauma or contact lens overuse

Common signs include blurred or distorted vision, eye pain, redness, excessive tearing, light sensitivity, or a feeling of something in your eye.

Specialized tests such as corneal topography, pachymetry, slit-lamp examination, and OCT imaging are used to evaluate corneal shape, thickness, and clarity.

If left untreated, yes — certain diseases like severe infections or advanced keratoconus can lead to scarring and vision loss. Early detection and treatment are key.

Treatment depends on the cause and may include lubricating drops, prescription medication, special contact lenses, cross-linking therapy, or in severe cases, a corneal transplant.

Keratoconus is not “curable,” but it can be managed effectively. Talk to your eye doctor about the options.

Only if they’re worn too long, not cleaned properly, or not fitted correctly. Always follow your eye doctor’s care instructions and replace lenses as recommended.

  • Practice good contact lens hygiene.
  • Use protective eyewear during sports or hazardous work.
  • Keep eyes lubricated if they’re dry.
  • Have regular eye exams, especially if you have allergies, wear contacts, or have family history of corneal disease.

 You should book an appointment immediately if you experience pain, sudden vision changes, light sensitivity, or persistent redness, as these can indicate corneal injury or infection.

Talk to your optometrist if you do not currently have a cornea specialist, or contact us to see one of our dedicated optometrists.
