Case report demonstrates suture repositioning improves visual acuity in a patient with a toric multifocal intraocular lens, suggesting effective management for subluxation.
Intraocular repair for subluxation of a multifocal intraocular lens (MFIOL) can be challenging, especially in toric models. Herein, we report a case of a 43-year-old man with a subluxated toric-type single-piece trifocal intraocular lens (IOL) with a C-loop that was spared using suture repositioning. Pars plana suturing was performed using the haptic externalization technique, and the tram-track suture technique was employed to flatten the tilted toric MFIOL. We also evaluated the postoperative toric axis and IOL position using anterior segment optical coherence tomography (AS-OCT) and a wavefront aberration analyzer. Postoperative AS-OCT revealed a 0.51 mm decentration and 8.7° tilt. The wavefront analysis revealed that the toric axis alignment was <5° from the target axis. The postoperative refractive error and residual astigmatism were minimal; the visual acuity at different distances was acceptable.
