    Corneal wound separations after penetrating keratoplasty can lead to graft failure. Early detection and management, particularly after suture removal, are crucial for preserving visual acuity and transplant success.

    Area of Science:

    • Ophthalmology
    • Transplant Surgery

    Background:

    • Corneal wound separations are a potential complication following penetrating keratoplasty.
    • Understanding the timing and causes of these separations is vital for improving patient outcomes.

    Purpose of the Study:

    • To analyze the incidence, timing, and contributing factors of corneal wound separations after penetrating keratoplasty.
    • To assess the impact of wound separations on graft survival and visual acuity.
    • To identify potential strategies for preventing wound separations.

    Main Methods:

    • Retrospective analysis of 40 cases with partial or full-thickness corneal wound separations post-penetrating keratoplasty.
    • Categorization of separations based on timing relative to suture removal.
    • Evaluation of graft failure rates and visual acuity outcomes.

    Main Results:

    • Corneal wound separations occurred in approximately 5.7% of penetrating keratoplasty cases.
    • Separations were grouped by occurrence before suture removal, immediately after, or long after.
    • Graft failure occurred in about 50% of wound separations, with full-thickness separations having a worse prognosis for visual recovery.

    Conclusions:

    • Wound separations occurring immediately after suture removal may be the most preventable.
    • Full-thickness wound separations significantly impact visual acuity recovery.
    • Delayed suture removal and enhanced wound healing evaluation may reduce the incidence of separations.
