Summary
Corneal collagen cross-linking successfully halted keratoconus progression after refractive surgery. Early screening for keratoconus is crucial for refractive surgery candidates to ensure long-term safety.
Area of Science:
- Ophthalmology
- Corneal Surgery
Background:
- Transepithelial photorefractive keratectomy (TEPRK) is a refractive surgery for myopia.
- Keratoconus is a progressive corneal ectasia that can be exacerbated by refractive surgery.
Observation:
- A 24-year-old male with a history of allergic conjunctivitis developed decreased night vision 5 years after TEPRK.
- Clinical diagnosis revealed bilateral keratoconus (keratoconus binoculus).
Findings:
- Corneal collagen cross-linking (CXL) using riboflavin was performed bilaterally.
- Confocal microscopy confirmed successful cross-linking and no progression of keratoconus over a 6-month follow-up.
Implications:
- CXL is an effective treatment for post-refractive surgery keratoconus.
- Comprehensive pre-operative screening for keratoconus is essential to mitigate risks associated with refractive surgery.
