Secondary in-the-bag Intraocular Lens Implantation in Aphakic Eyes After Vitrectomy and Silicone Oil Tamponade for Rhegmatogenous Retinal Detachment

Purpose: To describe a novel technique for capsular bag reopening and secondary in-the-bag intraocular lens (IOL) implantation in aphakic eyes after vitreoretinal surgery and intraocular tamponade. Methods: We enrolled 14 eyes of 14 patients who underwent primary vitreoretinal surgery with silicone oil tamponade for rhegmatogenous retinal detachment between September 2018 and September 2019. The novel technique was used for capsular bag reopening and foldable single-piece IOL implantation. Patients were followed up at least 24 weeks with routine ophthalmic examinations, corneal endothelial cell density, and IOL tilt and decentration measurement. Results: The procedure was successfully completed in 13 cases; in one case, because of posterior capsular tear, the IOL was implanted with ciliary sulcus fixation. After a mean follow-up of 48.8 ± 14.8 (range, 24.9–65.9) weeks, the best-corrected visual acuity (before 20/76 Snellen, 0.63 ± 0.23 logarithm of the minimum angle of resolution equivalent and after 20/35 Snellen, 0.32 ± 0.32 logarithm of the minimum angle of resolution equivalent; P = 0.001) and spherical equivalent (before +8.22 ± 4.08, after −2.39 ± 1.77 D; P < 0.001) improved, intraocular pressure (before 15.93 ± 4.40, after 16.25 ± 4.25 mmHg; P = 0.743) remained unchanged. The IOL was well centered with a mean horizontal and vertical tilt of 0.5070 ± 0.3319° and 0.4652 ± 0.3465°, respectively, and decentration of 0.1705 ± 0.1334 mm and 0.1712 ± 0.1576 mm, respectively. Conclusion: With this technique, capsular bag reopening and secondary in-the-bag IOL implantation could be achieved in most cases with satisfactory visual outcome and IOL position.
