Secondary Sulcus-Fixed Foldable IOL Implantation with 25-G Infusion in Patients with Previous PPV after Open-Globe Injury.

PURPOSE

To evaluate the safety and efficacy of secondary sulcus-fixed foldable intraocular lens (IOL) implantation through a clear corneal incision with 25-G infusion in patients with previous pars plana vitrectomy (PPV) after open-globe injury, and to analyze postoperative outcomes and prognostic factors of treatment.

METHODS

Clinical data of 89 eyes of 89 patients with open-globe injury who underwent secondary sulcus-fixed foldable IOL implantation through a clear corneal incision with 25-G infusion after vitrectomy in our hospital between January 2008 and June 2015 were retrospectively analyzed. The examinations before IOL implantation mainly included visual acuity, slit-lamp examination, direct and indirect ophthalmoscope, visual electrophysiology, corneal endothelium, B scan, ultrasound biomicroscope, and intraocular pressure. Five eyes underwent suturing of peripheral iris and 7 eyes underwent suturing of iris laceration simultaneously. The mean follow-up was 18 months with a range from 6 months to 8 years.

RESULTS

The mean interval between secondary sulcus-fixed foldable IOL implantation and vitrectomy was 2.8 months with a range from 2 to 6 months. The uncorrected visual acuity improved in all patients with a well-centered IOL ranging from 0.1 to 0.8 with the best-corrected visual acuity from 0.1 to 1.0 after secondary IOL implantation. The postoperative complications mainly included mild anterior chamber exudates in 10 eyes (11%), temporary IOP elevation in 12 eyes (13%), and recurrent retinal detachment in 5 eyes (6%), which were subsequently managed by surgery.

CONCLUSIONS

The interval of 2.8 months between vitrectomy and secondary IOL implantation is an appropriate and safe option to correct aphakia in patients receiving vitrectomy for open-globe injury.
