Long-term Comparison of Full-Bed Deep Lamellar Keratoplasty With Penetrating Keratoplasty in Treating Corneal Leucoma Caused by Herpes Simplex Keratitis

Advantages of full-bed DLK over PK are no allograft rejection, longer graft survival, earlier drug withdrawal of topical steroid and oral acyclovir, less recurrence of HSK, and fewer follow-up visits. Full-bed DLK is preferable for treating HSK-induced corneal scarring with relatively healthy endothelium and with no history of perforation.
