Modified Split-Thickness Corneal Patch Graft for Conjunctival Erosions in Patients With the Port Delivery System Implant: Surgical Technique and Long-Term Outcomes.

To describe the surgical technique and long-term outcomes of a modified split-thickness corneal patch grafting for conjunctival erosions that can be seen in patients with the Port Delivery System (PDS) implant. By way of retrospective review of medical records, this interventional case series identified 2 cases in which modified split-thickness corneal patch grafting was used to repair conjunctival erosion in patients with the PDS implant. The surgical approach involved creating a small opening in the corneal graft over the center of the PDS implant to improve visibility and allow for easier access during subsequent refill-exchange procedures. At the last follow-up of 6.9 years and 5.6 years, there was no recurrence of conjunctival erosions in either patient. The PDS implants remained well covered with the split-thickness corneal graft and had undergone multiple implant refills without complication or difficulty. Modified split-thickness corneal patch grafting with central graft aperture offers another option for long-term successful management of conjunctival erosions in patients with a PDS, especially those who have failed prior repair, by allowing sufficient visibility and access for subsequent refill-exchange procedures.
