Clinical Outcomes of the Triangular Suture Technique for Scleral Fixation of Dislocated Intraocular Lenses after Cataract Surgery
Abstract: Background: This study evaluates the safety and efficacy of a novel triangular suture technique (TST) as an alternative method to scleral-fixated intraocular lens (IOL) implantation in patients with IOL dislocation following cataract surgery. The aim is to assess visual outcomes, intraocular pressure (IOP) control, and complication rates over an extended follow-up period in a larger cohort. Methods: A retrospective cohort study analyzed 128 patients (demographics adjusted proportionally from prior data: approximately 48.8% female; mean age ~77.9 ± 10.3 years) who underwent scleral-supported IOL implantation using the TST. Preoperative assessments included ocular history, baseline visual acuity, and IOP. Postoperative follow-up was conducted at defined intervals over 26 months. All surgeries employed a uniform triangular scleral suture approach with 10-0 polypropylene in a three-point support pattern. Sutures were placed 3.0 mm posterior to the limbus at 11, 7, and 3 o'clock positions, with subconjunctival passage to prevent erosion and ensure proper IOL centration. Results: Uncorrected visual acuity (UCVA) improved significantly from 0.92 ± 0.55 to 0.50 ± 0.40 logMAR at 6 months (P < .01). Best-corrected visual acuity (BCVA) improved from 0.75 ± 0.34 to 0.36 ± 0.42 logMAR at 6 months (P < .01) and remained stable at 0.37 ± 0.50 logMAR at 26 months (P < .01). A transient IOP elevation occurred on postoperative day 1 (mean 18.14 ± 5.65 mm Hg; P < .05), normalizing thereafter with no long-term increases or added glaucoma medications. No significant complications (e.g., retinal detachment, endophthalmitis, vitreous hemorrhage, cystoid macular edema, suture erosion/breakage, or recurrent dislocation in the majority) were observed over the extended follow-up, with excellent IOL stability and centration. Conclusion: The TST provides a safe, effective, and mechanically balanced alternative to conventional scleral-fixated IOL methods, delivering significant sustained visual improvement, minimal complications, and stable anatomical outcomes in this expanded retrospective analysis.
