Abstract
Objective: To evaluate the surgical and clinical outcomes of deep anterior lamellar keratoscleroplasty using the anterior corneal cap of pre-cut donor tissues (for Descemet Stripping Automated Endothelial Keratoplasty - DSAEK) for limbal dermoid management.
Methods: Retrospective data from 39 eyes (37 patients) with limbal dermoid, treated between February 2013 and January 2017 at Vietnam National Institute of Ophthalmology.
Donor corneas for DSAEK were cut into anterior and posterior lamellae in the eye bank.
Anterior corneal caps were stored for up to 1 week in Optisol before being used as patch
grafts for deep anterior lamellar keratosleroplasty.
Results: Corneoscleral integrity was preserved in all cases. All 39 eyes had satisfactory cosmetic results after surgery. Thirteen (13) of the 39 eyes showed improved bestcorrected visual acuity after surgery. Fifteen patients’ astigmatism reduced by more than
0.75 diopters. Neo- vascularization at the graft–host junction and graft edema were noted
in 1 eyes and was treated using topical steroids.
Conclusion: The anterior cap obtained from pre-cut corneas for DSAEK can be used
as patch grafts for surgical management of limbal dermoids. This procedure achieved
satisfactory cosmetic and visual outcomes in our study, and might potentially maximize
the use of corneal tissues.
