Corneal Cross-Linking: Stop Keratoconus Progression
The only FDA-approved treatment that halts keratoconus progression. Strengthen your cornea and preserve your vision.
Schedule Consultation
What Is Keratoconus?
Keratoconus is a progressive eye disease in which the cornea thins and gradually forms a cone-like bulge. This causes blurred or distorted vision, frequent changes in eyeglass prescription, and increased astigmatism. It typically begins in puberty and progresses until around age 40.
Symptoms include:
- Blurred or distorted vision
- Increased sensitivity to light
- Frequent changes in eyeglass prescription
- High astigmatism
- Corneal scarring (in advanced cases)
What Is Corneal Cross-Linking?
Corneal cross-linking (CXL) is a minimally invasive procedure that strengthens corneal collagen fibers, halting the progression of keratoconus. It is the only FDA-approved treatment that can stop the disease from worsening.
Key Benefits
Stops keratoconus progression in >90% of patients
Prevents the need for corneal transplant
Preserves corneal tissue
Minimally invasive with rapid recovery
FDA-approved and proven effective
Can be combined with other treatments (e.g., topography-guided LASIK after stabilization)
Ideal Candidates
- Diagnosed with keratoconus (any stage, but earlier treatment is better)
- Progressive keratoconus (worsening over time)
- Adequate corneal thickness (typically ≥400 microns)
- No significant scarring
- Children and adults (age 14+)
Recovery & Results
Vision improvement
Vision typically stabilizes within 3 months. Some patients experience mild improvement; the primary goal is halting progression.
Timeline
Day 1-3
Mild discomfort if epithelium was removed; healing occurs quickly
Week 1
Vision stabilizes; return to light activities
Month 1-3
Refraction stabilizes
Long-term
Disease progression halted; vision preserved
Additional Treatments
Once keratoconus is stabilized, patients may be candidates for additional vision correction:
CTAK
(Corneal Topography-guided Transepithelial Ablation with Cross-linking)
An advanced surface ablation procedure that reshapes the cornea while strengthening it through cross-linking. It corrects refractive errors and irregular astigmatism while reinforcing corneal structure for long-term stability.
Topography-Guided LASIK
After stabilization, advanced LASIK can correct irregular astigmatism and improve vision.
Scleral Contact Lenses
Specialized lenses that vault over the cone and provide excellent vision and comfort.
FAQ
Will cross-linking improve my vision?
The primary goal is to stop progression. Some patients experience vision improvement, especially if the cornea was inflamed. Significant improvement typically requires additional procedures like Intacs or topography-guided LASIK.
Is cross-linking painful?
The procedure is painless due to anesthetic drops. Mild discomfort may occur for 1-2 days if the epithelium was removed.
Can cross-linking be reversed?
No, but the effect is permanent. Once collagen is cross-linked, the cornea remains strengthened indefinitely.
Will I need the procedure again?
In rare cases of disease recurrence, retreatment may be considered. Most patients require only one treatment.
Can cross-linking prevent the need for a corneal transplant?
In most cases, yes. By halting progression early, transplant can often be avoided.
