AI Article Synopsis
- A study was conducted to compare the effectiveness of two methods for attaching intraocular lenses (IOLs) during surgery: Gore-Tex sutures versus flanged intrascleral haptic fixation (FIHF).
- The study involved 79 eyes from 72 patients, with a follow-up period averaging about 16 months, and both techniques showed similar improvements in visual acuity by three months post-surgery.
- Results indicated that there was no significant difference in visual outcomes, refractive targets, or complication rates between the two fixation methods.
Article Abstract
Objective: To compare clinical outcomes of combined pars plana vitrectomy (PPV) and secondary scleral fixation of an intraocular lens (IOL) using Gore-Tex suture versus flanged intrascleral haptic fixation (FIHF) using double needles.
Design: Single-centre retrospective cohort series.
Participants: Eyes undergoing PPV with simultaneous scleral fixation of an IOL.
Method: Eyes that underwent fixation of a Bausch & Lomb Akreos AO60 or enVista MX60E IOL using Gore-Tex suture or a Tecnis ZA9003 or Zeiss CT LUCIA 602 IOL using FIHF were included. The primary outcome was change from baseline visual acuity to postoperative month 3. Secondary outcomes included deviation from refractive target aim and rates of postoperative complications.
Results: Seventy-nine eyes of 72 patients were included. Mean (±SD) follow-up was 16 ± 10.5 months (range, 4.5-45.2 months). Fifty-three eyes (67.1%) underwent Gore-Tex suture fixation, and 26 eyes (32.9%) underwent FIHF. Across all eyes, mean visual acuity improved from 1.30 ± 0.74 logMAR (20/399 Snellen equivalent) preoperatively to 0.36 ± 0.36 logMAR (20/45 Snellen equivalent) at 3 months (p < 0.001). No difference in visual acuity at month 3 was noted between the 2 techniques (p = 0.34). Mean deviation from refractive target aim was not significantly different between the Gore-Tex and FIHF groups (+0.14 ± 1.33 D vs -0.16 ± 0.88 D; p = 0.45). Reoperation rates were similar between groups (2 of 53 eyes in the Gore-Tex group vs 3 of 26 eyes in the FIHF group; p = 0.32).
Conclusion: Combined PPV and scleral fixation of IOLs with Gore-Tex suture and FIHF resulted in similar improvements in visual acuity. No significant differences in refractive outcome and postoperative complication profiles were noted.

Introduction: The aim of our study was to assess the outcome of Gore-Tex sutures in minimally invasive scleral fixation of subluxated posterior chamber intraocular lenses (PCIOLs) and to demonstrate a method for validating the lens position.
Methods: Retrospective study of patients who underwent lasso in-the-bag scleral fixation of a subluxated PCIOL using the snare technique with Gore-Tex suture from 2019 to 2021 in a single tertiary medical center. Functional outcome was analyzed by clinical assessment, and anatomical outcome, by ultrasound biomicroscopy (UBM).
Scleral fixated intraocular lens techniques for the vitreoretinal surgeon: an update.
Curr Opin Ophthalmol

Department of Research, Wills Eye Hospital, Philadelphia, PA.
Purpose Of Review: To describe recent evidence regarding surgical techniques for secondary scleral fixation of intraocular lenses (IOLs), with attention to information most relevant to the surgical practice of vitreoretinal surgeons.
Recent Findings: Recent studies have reported favorable outcomes in patients treated with scleral fixation of IOLs using Gore-Tex suture and flanged intrascleral haptic fixation (ISHF). ISHF can be achieved using trocar-cannulas or double needle-based techniques.

The circumareolar approach is one of the most popular and versatile in breast surgeries. Nevertheless, this approach usually implies a closure under tension which could lead to areolar distortion, scar widening and hypertrophic scarring. To prevent these complications, different surgical adjustments to this technique have been proposed, such as the Hammond's "Interlocking Gore-Tex suture.

Purpose: The purpose of this case series is to report three cases of exposed, unburied polytetrafluoroethylene (Gore-tex) sutures used for scleral fixated intraocular lenses and their management, including failure of pericardial patch and success of irradiated corneal patch. This series aims to inform management options for this uncommon adverse event.
Observations: A retrospective case series was conducted of three patients who presented at a tertiary care center with exposure of unburied Gore-tex sutures used for fixation of intraocular lens.
