Keratoconus: Patient Education About Progressive Corneal Disease Diagnosis
Summary
Keratoconus is a condition where the cornea, the clear front part of your eye, thins out and bulges into a cone-like shape. This can lead to blurry or distorted vision and frequent changes in your eyeglass prescription. There are various ways to manage keratoconus, including glasses, special contact lenses, and treatments that strengthen the cornea. Regular check-ups with your eye doctor are important to keep track of how the condition is progressing.
What Is This & Why It Matters
Keratoconus affects the cornea, changing its shape from round to cone-like. This change causes vision problems because the cornea is responsible for focusing light into your eye. Although it may sound scary, many people with keratoconus lead normal lives with proper treatment. The exact cause is not fully understood, but genetics may play a role. Early detection and treatment can help maintain good vision.
What You Should Do
- Schedule regular eye exams every 3-6 months to monitor changes in your vision.
- Wear glasses or contact lenses as prescribed by your eye doctor.
- Consider special contact lenses designed for keratoconus if regular lenses aren't effective.
- Discuss corneal cross-linking with your doctor to help stabilize the cornea.
- Protect your eyes from injury by wearing protective eyewear during activities like sports.
- Stay informed about new treatments and advances in keratoconus care.
What You Should NOT Do
- Do not ignore changes in your vision; report them promptly to your doctor.
- Avoid rubbing your eyes frequently, as this may worsen the condition.
- Don't skip follow-up appointments with your eye care specialist.
- Refrain from wearing ill-fitting contacts that cause discomfort or irritation.
- Do not self-prescribe over-the-counter eye treatments without consulting a doctor.
