Purpose:
To report a case of post laser in situ keratomileusis (LASIK), nebulomacular corneal opacity following a trauma induced flap dehiscence and was managed with superficial anterior lamellar keratoplasty (SALK).
Case Report:
A 32-year-old female underwent LASIK 2.5 years back, with a postoperative unaided visual acuity (VA) of 6/6 in both eyes. She was involved in a road traffic accident and sustained blunt trauma to the right eye 5 months before. At the time of presentation, the VA was 1/60 in the right eye. Slit lamp examination revealed flap dehiscence, stromal scar and descemet folds in that eye. There was a small macular scar in the parafoveal area due to a resolved Berlin's edema. SALK was performed in the affected eye. Unaided VA of 6/36 was noted on post- operative day 1. After 4 weeks of SALK surgery, best corrected VA was 6/24.
Conclusion:
This case highlights that flap adhesions are not very strong even years after LASIK and SALK may be an effective treatment option for post refractive surgery corneal opacities.
