Area of Science:

  • Ophthalmology
  • Corneal Surgery
  • Tissue Engineering

Background:

  • Corneal perforations pose a significant risk to globe integrity.
  • Timely and effective surgical repair is crucial for visual preservation.
  • Donor corneal rims are often discarded after penetrating keratoplasty.

Purpose of the Study:

  • To present demographic data and clinical outcomes of corneal perforations repaired with patch grafts.
  • To evaluate the efficacy of using residual donor corneal rims for patch grafts.
  • To assess the feasibility and advantages of this surgical technique.

Main Methods:

  • Retrospective evaluation of patients undergoing corneal perforation repair with patch grafts.
  • Data collection included demographics, perforation cause, tissue type, follow-up, and additional surgeries.
  • Patch grafts were prepared from residual donor corneas and sized to the wound.

Main Results:

  • Fifteen patients (mean age 64.9 years) with perforations due to inflammation, infection, or trauma were analyzed.
  • All patients maintained globe integrity; one required regrafting, three needed tarsorrhaphy, and two underwent penetrating keratoplasty for opacity.
  • Patch grafts demonstrated successful closure and preservation of the eye.

Conclusions:

  • Patch grafts are effective for maintaining globe integrity in corneal perforations.
  • This technique allows for tailored wound architecture and utilizes readily available donor corneal tissue.
  • Patch grafting is a valuable option in centers performing keratoplasty.
