Corneal perforation during laser in situ keratomileusis after hyperopic electrothermal keratoplasty

Management of Corneal Lacerations and Perforations

“…[9][10][11][12][13] Corneal perforation can occur because of excessive stromal bed dehydration from prolonged exposure to the operating microscope. 9 Unpredictable corneal thinning from prior procedures such as previous electrothermokeratoplasty scars has also caused perforations during LASIK ablation.…”

“…9 Unpredictable corneal thinning from prior procedures such as previous electrothermokeratoplasty scars has also caused perforations during LASIK ablation. 13 Rarely, machine malfunction can also cause repeated ablation at a single location, thereby causing a corneal perforation. 11 Recurrent and progressive epithelial downgrowth can complicate these perforations and be difficult to manage and thus, care should be taken to avoid manipulating or lifting the flap during repair.…”
