摘要

Background

The Yamane technique for sutureless scleral-fixated intraocular lens (YTSFIOL) implantation is an established option for visual rehabilitation in eyes without capsular support. However, evidence on ultra-short-term refractive outcomes and the influence of different vitreous management strategies remains limited.

Methods

This retrospective observational cohort study included consecutive adult patients who underwent YTSFIOL implantation by a single surgeon at a tertiary centre. Ultra-short-term outcomes were defined as visual and refractive outcomes assessed at six weeks postoperatively. Best-corrected visual acuity (BCVA), spherical equivalence (SE), refractive astigmatism, and corneal astigmatism were analysed and compared between eyes that underwent anterior vitrectomy (AV) and pars plana vitrectomy (PPV).

Results

Thirty-one eyes of 30 patients were included. Mean BCVA improved significantly from 0.25 ± 0.24 logMAR preoperatively to 0.14 ± 0.10 logMAR at six weeks postoperatively (p = 0.041). Mean SE improved from + 4.83 ± 7.39 D to − 0.70 ± 0.90 D (p < 0.001). Both refractive and corneal astigmatism increased significantly at six weeks. No statistically significant differences were observed between AV and PPV groups in postoperative BCVA, SE, refractive astigmatism, corneal astigmatism, or SE prediction error (all p > 0.05). Early postoperative complication rates were comparable between groups (p = 0.335).

Conclusion

YTSFIOL implantation provides significant improvement in visual acuity and predictable refractive outcomes as early as six weeks postoperatively, irrespective of vitreous management strategy.
