Evaluating the Efficacy of a Novel Triangle Suture Technique in Scleral-Fixation of Intraocular Lens.

PURPOSE: The study aims to evaluate the efficacy and safety of a novel Triangle Suture Technique in the surgical placement of Scleral-Fixated Intraocular Lenses (SFIOLs). The research seeks to address the challenges in cases associated with inadequate capsular support for Intraocular Lens (IOL) implantation, offering an alternative to traditional methods.

METHODS

This A pilot retrospective case series evaluated the efficacy and safety of a novel Triangle Suture Technique for scleral-fixation of intraocular lenses (SFIOL) using 10-0 Polypropylene suture (Prolene; Ethicon, Inc) in patients with dislocated IOLs. Visual acuity outcomes, intraocular pressure control, and post-operative complications were assessed.

RESULTS

The study comprised 52 eyes from 49 patients (mean age 80.3±10.3 years). Mean pre-operative uncorrected visual acuity (UCVA) significantly improved from 1.14±0.84 to 0.61±0.56 logMAR at 3 months (P=0.001). Best-corrected visual acuity (BCVA) also improved from 0.84±0.65 to 0.54±0.56 logMAR at 3 months (P=0.048). Glaucoma drop usage decreased from 0.67±1.09 to 0.25±0.62 types at 6 months (P=0.018). Peri-operative complications included anterior segment complications in 4 eyes (7.54%) and posterior segment complications in 1 eye (1.9%). While non-recurrent IOL dislocation occurred in 45 eyes (86.5%), recurrent dislocation was noted in 7 eyes (13.5%), with one eye experiencing twice recurrent dislocation (1.9%).

CONCLUSION

The triangle suture technique is a versatile and accessible option for scleral fixation of various IOL designs. While these preliminary results demonstrate anatomical efficacy, the study's retrospective nature, small cohort, and single-surgeon experience necessitate a cautious interpretation. Further large-scale, comparative studies are required to establish long-term stability and clinical efficacy relative to current gold-standard methods.
