PURPOSE: The aim of this study was to compare the effectiveness of amniotic membrane plugging (AMP) versus acellular porcine corneal stroma (APCS) partially penetrating deep anterior lamellar keratoplasty (PP-DALK) in the treatment of small corneal perforation.
METHODS: A total of 44 patients (44 eyes) with small corneal perforation (<3 mm in diameter) were retrospectively included. Among them, 24 eyes were treated with AMP (AMP group), and 20 eyes were treated with APCS-PP-DALK (APCS-PP-DALK group). The best-corrected visual acuity (BCVA), corneal transparency, ocular irritation symptoms, corneal thickness, primary disease control, postoperative complications, and survival rate were assessed.
RESULTS: Both groups showed significant postoperative improvement in BCVA versus baseline (both p < 0.001), with no difference in overall visual outcome between APCS-PP-DALK and AMP groups (p = 0.607). Corneal transparency was better in the APCS-PP-DALK group at 1, 3, and 6 months compared with the AMP group (all p < 0.05), though this difference resolved by 12 months. Corneal thickness increased significantly in both groups after surgery, with the APCS-PP-DALK group exhibiting greater thickness than the AMP group at 6 months (p < 0.001). The primary disease control rate was 85% in the APCS-PP-DALK group and 87.5% in the AMP group, yielding no statistically significant difference between the groups (p = 0.810). Furthermore, the incidence of postoperative complications was comparable between the two groups (p = 0.844).
CONCLUSION: Both AMP and APCS-PP-DALK are effective and safe treatments for small corneal perforation.
