Copyright ? 2023 Published by Wolters Kluwer on behalf of ASCRS and ESCRS.Purpose:To assess the long-term (5-year) results and complications of the double-flanged polypropylene technique in patients with capsular tension segment fixation, nonfoldable intraocular lens (IOL) scleral fixation, and foldable IOL scleral fixation.Setting:Santa Casa de Belo Horizonte and Centro Oftalmológico de Minas Gerais.Design:Prospective case series.Methods:Eyes that underwent treatment using the double-flanged polypropylene technique between September 2016 to September 2021 were included. LogMAR visual acuity was recorded, as well as complications such as long-term polypropylene resistance, conjunctival erosion, conjunctival inflammation, flange exposure, internalization, endophthalmitis, retinal detachment, and cystoid macular edema.Results:71 eyes of 61 patients were evaluated. The mean follow-up period for these eyes was 28.2 ± 14.3 (min: 4; max: 60; median: 26) months. 173 flanges were performed. 13 cases with sub-Tenon flanges (7.5%) were observed. 5 exposed flanges (2.89%), presented after a mean of 1.8 weeks postoperatively, were observed. 1 patient with large flanges presented with conjunctival inflammation and hyperemia. 2 late internalized flanges (1.1%) and 2 recently internalized flanges (1.1%) were observed. 3 eyes (4.22%) had retinal detachment. Moreover, cystoid macular edema was detected in 3 eyes (4.22%). No cases of endophthalmitis were observed.Conclusions:The double-flanged technique was proven to be stable when the correct technical procedure was followed. However, complications can be observed, especially with short scleral tunnels and in eyes where the flanges were not buried inside the sclera.
