Purpose: The purpose of this study was to evaluate the clinical outcomes of the TissueTuck technique in the management of pterygium. Methods: This was a single-center, retrospective review of patients with primary or recurrent pterygium that underwent surgical excision followed by application of cryopreserved amniotic membrane (AM) using the TissueTuck technique. All patients underwent surgery between January 2012 and May 2019. Patient profile, surgical time, complications, and rates of pterygium recurrence were analyzed. Results: A total of 582 eyes of 453 patients (328 female patients; 65.1 ± 13.9 years) were included for analysis and initially presented with primary (92%) pterygium. The average duration of pterygium excision surgery was 14.7 ± 5.2 minutes (median: 14, range: 4–39 minutes) with mitomycin C administration in 257 (45%) eyes. At the last follow-up of 30.2 ± 22.2 months (median: 24.5, range: 3–94 months), BCVA significantly improved from logMAR 0.23 at baseline to logMAR 0.19 (P < 0.0001). Recurrence rate was 2.3% but only 0.7% (2/274) in those cases with primary, single-headed pterygium without mitomycin C treatment. Other postoperative complications in that cohort included granuloma (7.9%), scarring (3.8%), and diplopia in extreme lateral gaze (2.5%). The AM remained secured to the ocular surface throughout the postoperative period. Conclusions: The TissueTuck surgical technique with cryopreserved AM can be performed in minimal time and result in a low recurrence and complication rate after pterygium surgery.
