To present a new technique using the recently introduced Enduragen(®) material (Tissue Science Laboratories) as a patch graft for exposed ocular implants.


A retrospective, interventional, non-comparative case series of 3 patients who had Enduragen patch grafts for the closure of Tenon's capsule and conjunctiva over exposed ocular implants. Medical records were reviewed and the following parameters were collected: age, gender, indication for surgery, type of surgery, laterality, type of orbital implant, complications after repair and length of follow-up.


Three patients were identified, 2 males and 1 female. One patient had a secondary quad-motility implant with supertemporal exposure. The second patient had a secondary implant with a fistula at the lateral aspect of the socket. The third patient had a centrally exposed primary hydroxyapatite implant. All patients received Enduragen patch grafts to cover the implant. Follow up ranged from 40 to 43 months (mean, 41.3 months; SD, ± 1.5). None of the 3 patients had any signs of implant re-exposure at the time of the last post-operative visit. There were no intra-operative or early complications observed.


This consecutive case series suggests that Enduragen could be used as a safe and effective patch graft for exposed ocular implants. However, a larger prospective study with longer follow-up would be useful in further defining the indications and limitations of the Enduragen patch graft for the treatment of exposed orbital implants.
