Supplementary Material for: Three-Year Follow-Up of Results of Intraocular Lens Fixation in Patients with Retinitis Pigmentosa

This is a retrospective, consecutive, noncomparative case series of 6 eyes of 5 RP patients who had undergone PPV and IOL implantation. The aim of this case series was to report the long-term outcomes of pars plana vitrectomy (PPV) with intraocular lens (IOL) implantation in patients with retinitis pigmentosa (RP). The surgical procedures, visual function, refractive error, corneal endothelial cell density, intraocular pressure, and retinal morphology were evaluated before and three years after the surgery. Six eyes of 5 RP patients that had undergone PPV and IOL implantation with or without suturing for lens dislocation were studied. The visual acuity was maintained or improved at 3 years after surgery in all 6 eyes. No intraoperative complications occurred in any of the cases. The mean deviation of the Humphrey Field Analyzer 10-2 program and the retinal morphology evaluated by optical coherence tomography did not show any abnormal changes before and after surgery. In two eyes, the postoperative refractive error was more myopic than the attempted refractive error. In conclusion, PPV with IOL implantation can be performed safely in RP patients, and the long-term visual acuity can be maintained.
