Burr-Assisted Anterior Lamellar Keratoplasty (DALK) in Patients with Corneal Stromal Scarring: A Case Series

Ophthalmol Ther. 2020 Jun;9(2):343-347. doi: 10.1007/s40123-020-00248-8. Epub 2020 Apr 11.

Abstract

Purpose: To describe a modified technique of deep anterior lamellar keratoplasty (DALK) assisted by diamond ophthalmic burr (DOB) in two patients with corneal stromal scarring.

Methods: Two patients with corneal stromal scarring underwent a modified DALK technique with corneal stromal polishing assisted by a DOB until the level of the Descemet membrane.

Results: There were no intra- or postoperative complications. Six months postoperatively, the corneal graft was clear, while corrected distance visual acuity improved in both cases.

Conclusions: Burr-assisted DALK seems to represent an alternative surgical technique in patients with corneal stromal scarring.
