Keratoconus

What is it? Keratoconus is a progressive, non-inflammatory eye disorder where the normally round, dome-shaped cornea gradually thins and bulges outward into a cone-like shape. This structural change typically begins in adolescence or early adulthood and worsens over 10–20 years before stabilizing. The irregular corneal surface causes light entering the eye to scatter and focus improperly on the retina, resulting in significant visual distortion that cannot be fully corrected with standard glasses. While the exact cause is unknown, keratoconus involves a breakdown of collagen fibers in the cornea, possibly influenced by genetic predisposition, oxidative stress, chronic eye rubbing, or conditions like allergies and Down syndrome. Early detection is critical, as modern treatments can halt progression and preserve vision.

Common Symptoms

  • Gradual blurring and distortion of vision at all distances
  • Increased sensitivity to light (photophobia) and glare, especially at night
  • Frequent changes in eyeglass prescription that no longer provide clear vision
  • "Ghosting" or multiple images when looking at a single object
  • Difficulty with night driving due to starbursts or halos around lights
  • Eye strain or headaches after visual tasks
  • Sudden worsening of vision if acute corneal hydrops occurs (rare complication)

Risk Factors

  • Family history of keratoconus (about 10% of cases are familial)
  • Chronic eye rubbing due to allergies, asthma, or eczema
  • Connective tissue disorders (Ehlers-Danlos, Marfan syndrome)
  • Down syndrome or other genetic conditions
  • Prolonged exposure to UV light without protection
  • Age: typically diagnosed between ages 10–30

Treatment Options

  • Early Stage: Custom soft contact lenses or rigid gas-permeable (RGP) lenses to create a smooth optical surface.
  • Corneal Cross-Linking (CXL): A minimally invasive procedure using riboflavin (vitamin B2) drops and UV light to strengthen corneal collagen and halt progression. This is the gold standard for stopping disease advancement.
  • Specialty Lenses: Scleral lenses, hybrid lenses, or piggyback systems for advanced irregularity.
  • Intacs®/Corneal Rings: Small plastic inserts placed in the cornea to flatten the cone and improve lens fit.
  • Corneal Transplant: Penetrating keratoplasty (full-thickness) or deep anterior lamellar keratoplasty (DALK) for severe cases where other treatments fail.

Prevention & Lifestyle Tips

  • Avoid eye rubbing at all costs—this is the most important modifiable risk factor.
  • Manage allergies aggressively with antihistamine drops to reduce itching.
  • Wear UV-protective sunglasses outdoors.
  • Attend regular corneal topography screenings if you have a family history.
  • Use preservative-free artificial tears to keep the ocular surface comfortable.

When to See a Doctor Seek evaluation if you notice rapidly changing vision, increasing astigmatism, or difficulty achieving clear vision with new glasses—especially if you are under 30. Doctor's Note: Keratoconus is no longer a condition that inevitably leads to transplant. With early diagnosis and corneal cross-linking, over 90% of patients can stabilize their vision and avoid surgery. If you rub your eyes due to allergies, treating the allergy is part of treating keratoconus.
