Aims The aim of this study was to assess the efficacy and safety of pre-Descemet's membrane (DM) sutures associated with intracameral air injection for management of acute corneal hydrops associated with keratoconus.

Methods We carried out a retrospective interventional study of seven consecutive cases. Three to seven pre-DM sutures with 10-0 nylon were applied perpendicularly to the tear as close as possible to DM, under general anaesthesia. An air bubble was injected into the anterior chamber at the end of each procedure.

Results Corneal oedema began to decrease from day 1 after surgery in all our patients. Best-corrected visual acuity progressed from 2.13 to 1.65 logMar (p=0.031) 1 month after surgery, and from 2.13 to 0.84 logMar (p=0.016) 2 months after surgery. The mean corneal thickness measured by anterior segment optical coherence tomography decreased from 1472 µm (range 689–2770 µm) on day 0 to 909 µm (range 484–1640 µm) on day 1 (p=0.016), 716 µm (range 484–1380 µm) on day 15 (p=0.016) and 528 µm (range 404–618 µm) 1 month after surgery.

Conclusions Our results suggest that intrastromal pre-DM sutures and intracameral air injection could promptly restore imperviousness of posterior stroma. This technique seems to be a safe and useful procedure to shorten acute corneal hydrops.
