Keratoconus is a progressive eye condition characterized by the thinning and bulging of the cornea, resulting in a cone-like shape. This abnormality of the cornea can cause significant visual impairment, as it affects the way light enters the eye. By recognizing the symptoms early on, seeking proper diagnosis, and exploring traditional and emerging treatment options, individuals with keratoconus can live a fulfilling life and maintain good visual function.

Symptoms of Keratoconus

Recognizing the symptoms of keratoconus is crucial for early diagnosis and effective management of the condition. One of the first signs of keratoconus is a gradual blurring of vision that cannot be corrected with glasses. This is often accompanied by frequent changes in prescription, as the shape of the cornea continues to change over time.

Another common symptom is the appearance of halos or ghosting around lights, particularly at night. This is due to the irregular shape of the cornea, which causes light to scatter instead of focusing properly on the retina. Patients with keratoconus may also experience increased sensitivity to light, making it uncomfortable to be in bright environments.

Diagnosing Keratoconus

During an eye exam, your eye doctor will perform a series of tests to diagnose keratoconus and determine the severity of the condition. These tests may include:
 

• Visual Acuity Test: This test measures how well you can see at different distances. You will be asked to read letters from a chart, and your eye care professional will determine your visual acuity based on your ability to correctly identify the letters.
• Corneal Topography: This non-invasive test maps the shape of your cornea and identifies any irregularities. It is performed using a special instrument called a corneal topographer, which creates a detailed map of the corneal surface.
• Slit-lamp Examination: This examination allows your eye care professional to examine the front part of your eye, including the cornea, using a microscope called a slit lamp. It helps to visualize any structural abnormalities or thinning of the cornea.
• Pachymetry: This test measures the thickness of your cornea. It is important in diagnosing keratoconus, as the cornea tends to become thinner in affected individuals.

Based on the results of these tests, your optometrist will be able to diagnose keratoconus and determine the appropriate treatment options for you.

Treatment Options for Keratoconus

Treatment options for keratoconus may include:
 

• Glasses or Contact Lenses: In the early stages, eyeglasses or soft contact lenses may be used to correct the mild nearsightedness and astigmatism associated with keratoconus.
• Rigid Gas Permeable (RGP) Contact Lenses: RGP lenses can provide better visual acuity by creating a smooth, uniform surface over the irregular shape of the cornea.
• Scleral Lenses: These larger, gas-permeable lenses vault over the cornea and rest on the sclera, providing improved comfort and visual acuity for some individuals with keratoconus.

Regular follow-up appointments are crucial to monitor the condition and ensure appropriate management.
