PURPOSE: Complications such as explosive choroidal hemorrhage, residual cortex, and capsule rupture often occur during intraocular surgery combined with penetrating keratoplasty (PKP) due to poor maintenance of the anterior chamber. To address these challenges, the authors have innovatively used a sterile polyethylene instrument cover to temporarily reconstruct the anterior chamber.
METHODS: In this report, the authors describe a technique where a "temporary corneal patch" was created from a sterile instrument cover, using a trephine to ensure a diameter approximately 1 mm to 2 mm wider than the corneal bed or perforation. This patch was then sutured into the host corneal bed or the perforation with 10-0 nylon sutures during intraocular surgery combined with PKP. Each case was evaluated for surgical efficacy and complications.
RESULTS: The authors successfully applied this technique in three cases of combined corneal transplantation surgery. In two cases, PKP, phacoemulsification, and intraocular lens implantation were successfully performed. In the third case, PKP, vitrectomy, and other intraocular procedures were performed. No intraoperative or postoperative complications were observed.
CONCLUSION: The use of a sterile polyethylene material as a temporary corneal patch for anterior chamber reconstruction represents a safe, effective, and cost-efficient approach for intraocular surgery combined with PKP or posterior segment surgery as a keratoprosthesis.
