Summary
A new corneal iron deposit, the "pseudo-Fleischer ring," has been identified after hyperopic laser in situ keratomileusis (LASIK) eye surgery. This finding is similar to Fleischer rings seen in keratoconus.
Area of Science:
- Ophthalmology
- Corneal Surgery
- Refractive Surgery
Background:
- Laser in situ keratomileusis (LASIK) is a common refractive surgery procedure.
- Hyperopic LASIK aims to correct farsightedness.
- Corneal iron deposits, such as the Fleischer ring in keratoconus, are known ocular findings.
Observation:
- A 37-year-old woman developed bilateral corneal epithelial pigmentation six months after hyperopic LASIK.
- The observed pigmentation formed a ring pattern on both corneas.
- The pattern resembled the iron deposits characteristic of the Fleischer ring in keratoconus.
Findings:
- This case represents the first reported instance of a corneal iron line associated with hyperopic LASIK.
- The authors termed this finding the "pseudo-Fleischer ring."
- Corneal iron deposits have been previously documented after various ocular surgeries.
Implications:
- The "pseudo-Fleischer ring" may be a novel, previously unreported finding after hyperopic LASIK.
- Understanding this phenomenon is important for post-LASIK monitoring and diagnosis.
- Further research is needed to determine the prevalence and clinical significance of the pseudo-Fleischer ring.
