PurposeTo compare the clinical and refractive outcomes of anterior vitrectomy (AnV) and pars plana vitrectomy (PPV) in patients undergoing modified Yamane intrascleral fixation for secondary intraocular lens (IOL) implantation.MethodsIn this retrospective, comparative study, 74 eyes of 74 patients who underwent modified Yamane intrascleral fixation between January 2021 and August 2024 were included. Patients were categorized into two groups: AnV (n = 45) for subluxated IOLs and PPV (n = 29) for nucleus drop or IOL luxation. Postoperative visual acuity (uncorrected UDVA and corrected distance CDVA), refractive stability, IOL tilt, endothelial cell count (ECC), lenticular astigmatism, and complications were assessed. IOL tilt was measured by using swept-source optical coherence tomography.ResultsPostoperative UDVA and CDVA were significantly higher in the AnV group (p p = 0.591). Corneal astigmatism was lower in the AnV group (-1.00 D vs. -1.75 D, p 2, p p = 0.591). Postoperative lenticular astigmatism values were similar between the groups (p = 0.124). Lenticular astigmatism correlated with IOL tilt (r = 0.794, p p = 0.383, p = 0.780).ConclusionsBoth AnV and PPV yielded comparable refractive and IOL positioning outcomes in modified Yamane intrascleral fixation. However, AnV demonstrated superior endothelial preservation, lower corneal astigmatism, and better visual acuity, suggesting an advantage.
