Purpose:
To compare therapeutic outcomes of three surgical approaches for acute corneal hydrops (ACH): compression sutures combined with intracameral air injection (CSAI), CSAI followed by deep anterior lamellar keratoplasty (DALK), and penetrating keratoplasty (PKP).
Methods:
This study enrolled 26 patients (26 eyes) into three groups: CSAI-only (7 eyes), CSAI+DALK (14 eyes), and PKP (5 eyes). Demographics; best-corrected visual acuity (BCVA), corneal edema area, central corneal thickness (CCT), corneal curvature during the acute phase; resolution time after CSAI; BCVA, corneal curvature, CCT, astigmatism at final follow-up; and complications were collected.
Results:
Mean corneal edema resolution time after CSAI was approximately 2 weeks. Postoperative BCVA (logMAR) improved in all groups (p < 0.05): CSAI-only (0.60 ± 0.15), CSAI+DALK (0.34 ± 0.16), PKP (0.15 ± 0.09). Among 17 eyes planned for DALK, Descemet's membrane perforation occurred in 5 eyes. One PKP case had graft rejection, no long-term complications in the other two groups.
Conclusions:
CSAI shortens ACH duration but offers limited visual improvement, serving as a phased treatment. DALK after CSAI resolution significantly improves BCVA and reduces graft rejection risk, making CSAI+DALK a preferred balanced approach. PKP provides the greatest BCVA but carries higher rejection risk, reserved for non-suitable cases of other options.

Guidelines for Writing Outcome
Patient outcomes reflect the patient's response to the goal rather than what the nurse aims to achieve. Terminology should be observable and measurable to avoid the reader's interpretation. The desired outcome should be realistic and achievable in the designated care timeframe. Expected outcomes should align with adjunctive therapies. The outcome should enhance care...
