Core Tip
Core Tip: Eccentric semilunar penetrating keratoplasty represents a viable tissue-sparing surgical option for managing acute peripheral corneal perforations secondary to chemical injury. This approach preserves the healthy central optical zone, minimizes antigenic load, and reduces the risk of immunologic rejection compared to total penetrating keratoplasty, while achieving the primary goal of globe salvage. However, the procedure presents significant technical challenges, including severe hypotony, anterior chamber collapse, and iris incarceration, requiring manual recipient bed preparation and viscoelastic-assisted chamber reformation. This emergency tectonic strategy preserves the central corneal architecture, maintaining the option for future optical keratoplasty if visual rehabilitation remains insufficient.
