Acute Sterile Keratolysis After Deep Anterior Lamellar Keratoplasty in a Patient With Keratoconus: A Case Report.

This is the first reported case of sterile keratolysis after the use of GISC lenticule in DALK in a healthy patient with keratoconus. The underlying pathophysiology is not clearly understood, and some theories have been proposed in this report. Surgeons need to be aware of this rare complication and are encouraged to have a low threshold for graft replacement to ensure good clinical and visual outcomes. Developing a prospective complication registry to document complications after the use of GISC lenticules in ophthalmic surgery is recommended.
