Purpose: To describe and evaluate the clinical outcomes of the Flanged Prolene Suture intraocular lens fixation (PIF) technique and compare it to anterior chamber IOL (ACIOL) implantation.
Design: A retrospective comparative review.
Methods: A retrospective comparative review of consecutive patients undergoing secondary IOL implantation was performed. A comparison between patients that had ACIOL and PIF technique was conducted. The main outcome measures were changes in best-corrected visual acuity (VA), IOL position and complications.
Results: In the study period, fourteen eyes had ACIOL implantation and ten eyes had PIF surgery. VA acuity for both groups combined improved from 1.27 ± 0.65 logMAR preoperatively to 0.84 ± 0.65 logMAR (P< 0.0001). Seventeen patients had VA measurements in the year before the IOL dislocation. In those seventeen patients, VA changed from a baseline of 0.90 ± 0.68 to 0.97 ± 0.61 logMAR in the PIF group (p=0.334) and from 0.54 ± 0.27 to 0.85 ± 0.65 logMAR in the ACIOL group (p=0.145). No intraoperative or early postoperative complications were documented in either group. Two (20%) patients in the PIF group developed CME and one patient developed corneal edema. In the ACIOL group, one patient developed significant CME and two patients developed visual significant corneal edema.
Conclusion: The PIF technique seems to offer a simple, fast and safe way to fixate an IOL posteriorly. In our experience, the learning curve of the technique is short with a low complication rate and good visual outcomes.
