PURPOSE: To introduce a modified capsular hook technique for managing intraocular lens-capsular bag complex (IOLCBC) subluxation and compare its outcomes with conventional transscleral IOL fixation.
METHODS: A modified implantation technique using polypropylene suture hooks introduced from within the capsular bag, combined with transscleral flanged-node fixation was developed to preserve capsular integrity. Seventeen eyes with in-the-bag IOL-CBC subluxation were included: 10 treated with the modified capsular hook implantation technique and 7 with conventional transscleral fixation. Outcomes at ≥6 months were compared, including surgical duration, IOL decentration and tilt, higher order aberrations (HOAs), visual function, postoperative complications, and patient-reported satisfaction.
RESULTS: The capsular hook group had a significantly shorter surgical duration and demonstrated smaller IOL decentration (0.35 ± 0.22 vs 1.23 ± 0.82 mm) and tilt (2.09 ± 1.51° vs 5.76 ± 4.13°) compared with the transscleral fixation group (all P < .05). Corrected distance visual acuity, contrast sensitivity, and total HOA were comparable between groups, whereas internal HOAs and endothelial cell density loss were relatively lower in the capsular hook group. Patient-reported visual function and quality of vision were higher in the capsular hook group. No cases of suture erosion, chronic inflammation, or recurrent IOL subluxation occurred.
CONCLUSIONS: The modified capsular hook technique provides a safe and minimally invasive alternative for managing IOL-CBC subluxation. By preserving capsular integrity, facilitating stable in-the-bag fixation, and offering improved IOL stability, it may serve as a practical option for eyes with compromised zonular support.
