Flap Complications after Redo in Laser in Situ Keratomilusis

Purpose: To evaluate the incidence and type of complications of flap elevation and reposition in cases where enhancements were done after LASIK. Method: A retrospective interventional case series comprised 27 eyes of 25 female patients were done over a period of 9 years. Redoes were done 3 to 10 months after the initial LASIK procedure. Flap elevation was performed manually in all cases using the same technique. Results: In 18 eyes (66%), the procedure was completed without complications, in 6 (22%) eye epithelial ingrowth occurred but was limited to the periphery of the corneal flap without any effect on the vision or flap integrity, in 1 (3.7%) eye epithelial ingrowth was more aggressive reaching the visual center causing marked effect on the vision, stromal and flap integrity and 2 eyes (7.4%) experienced diffuse lamellar keratitis.
