Different compression sutures combined with intracameral air injection for acute corneal hydrops

AIM: To evaluate the efficacy and safety of full-thickness sutures combined with intracameral air injection (FTS-AI) versus pre-Descemet’s membrane sutures combined with intracameral air injection (PDS-AI) in the management of acute corneal hydrops in keratoconus. METHODS: The research included 8 patients (8 eyes) suffering from acute corneal hydrops caused by keratoconus. Four patients were randomly assigned to FTS-AI. And the other four were randomly assigned to PDS-AI. Corneal oedema, visual acuity, corneal thickness were assessed during follow-up. RESULTS: The demographics, preoperative duration of symptoms and severity of corneal hydrops between the two groups were not significantly different. The mean corneal oedema resolution time after FTS-AI and PDS-AI were 11±1.15 and 15±1.41d, respectively (P=0.005). The maximum corneal thickness of the scarred region decreased in both groups at one week postoperatively (P
