Abstract
Background: Polypropylene is a commonly used suturing material for intraocular lens (IOL) scleral fixation, but a high breakage rate after several years of follow-up is reported. Meanwhile, Gore-Tex has been a popular artificial material in ophthalmic surgery. Aim: This pilot study investigated the safety and efficacy of a modified surgical technique for scleral fixation of a four-point, close-loop haptic IOL using Gore-Tex as the suture material for aphakic patients without adequate capsular support. Methods: A modified IOL scleral fixation technique was developed using a four-point, close-loop haptic IOL and Gore-Tex as the suture material. Patients undergoing the operation between March 2018 and May 2019 at one center were included in the study. The preoperative uncorrected distance visual acuity (UDVA) with spectacles and postoperative UDVA with an IOL were compared as the main outcome. Follow-up time was 17–43 months. Results: A total of 10 eyes of 10 patients were enrolled, including 3 with iatrogenic IOL dislocation, 3 with iatrogenic lens drop, 2 with traumatic lens dislocation, and 2 with late in-the-bag IOL dislocation. The mean age was 70.8 ± 12.11 years. The mean UDVA, evaluated by the logarithm of the minimum angle of resolution, was decreased from preoperative 1.89 ± 0.28 to postoperative 0.58 ± 0.70 (P < 0.001). No complications were reported except in one case with a postoperative corneal ulcer which healed after antibiotic treatment. Conclusion: The favorable outcome suggests Gore-Tex sutures as a safe and stable material for IOL scleral fixation. Prospective studies with a larger sample size would be necessary for more details on the safety and efficacy of the Gore-Tex suture in IOL scleral fixation.
