AbstractPurpose: To describe the surgical technique and outcomes of "wet-peeling" deep anterior lamellar keratoplasty (DALK) using sterile water and blunt dissection in cases with corneal scarring after healed corneal hydrops.Methods: Manual DALK using a "wet-peeling" technique was performed in 20 eyes of 20 consecutive patients with healed corneal hydrops between June 2011 and October 2013.Results: Intraoperative microperforations were encountered in 2 (10%) cases. None of the cases required conversion to penetrating keratoplasty. There was significant improvement in mean best-corrected visual acuity at the end of 24 months post-operatively (0.99 +/- 0.30 logMAR vs. 0.20 +/- 0.11 logMAR; P<0.001). The postoperative mean residual stromal bed thickness was 48.9 +/- 5.9 mm, and mean central corneal thickness was 557.2 +/- 50.3 mu m. The mean endothelial density was 2021 +/- 236 cells/mm(2) at the final follow-up.Conclusions: Manual DALK using sterile water can be successfully performed in corneas with healed hydrops. Favorable visual outcomes may be attributed to thin residual bed thickness postoperatively.
