Summary
A new circular flap rhexis technique for retreatment after Laser in situ keratomileusis (LASIK) effectively reduces epithelial complications. This method minimizes epithelial damage, lowering risks like epithelial ingrowth and flap melting in LASIK retreatment cases.
Area of Science:
- Ophthalmology
- Refractive Surgery
- Corneal Surgery
Background:
- Laser in situ keratomileusis (LASIK) retreatment carries higher risks of epithelial complications than primary LASIK.
- Epithelial ingrowth and flap melting are common issues following LASIK retreatment.
Purpose of the Study:
- To introduce and evaluate a novel technique, circular flap rhexis, for LASIK retreatment.
- The aim is to decrease epithelial damage and associated complications during LASIK retreatment.
Main Methods:
- The circular flap rhexis technique involves precise flap edge identification, a linear epithelial tear, and careful flap replacement.
- This technique was applied to 43 eyes undergoing LASIK retreatment 3-6 months after the primary procedure.
- Epithelial ingrowth and flap melting rates were monitored over a 12-month follow-up period.
Main Results:
- Epithelial ingrowth occurred in 9.3% of eyes, and flap melting in 2.3% after 12 months.
- These complications were peripheral and did not impact visual acuity or corneal astigmatism.
- The circular flap rhexis technique demonstrated a reduction in epithelial complications.
Conclusions:
- LASIK retreatment utilizing the circular flap rhexis technique is effective.
- This approach successfully reduces epithelium-related complications post-LASIK retreatment.
- The technique promotes better flap adhesion and minimizes adverse epithelial responses.
