Clinical Outcomes Of Scleral Suture Fixated Intraocular Lenses

To investigate the visual acuity outcomes and post-operative secondary surgical rates using a scleral-fixated intraocular lens (IOL) using a 4-point suture fixation technique

A single-center retrospective chart review

A retrospective observational study of 169 eyes that underwent conventional sutured scleral fixation was performed over a six-year study period. The primary outcomes were uncorrected visual acuity (UCVA) and best corrected visual acuity (BCVA), assessed at the preoperative and postoperative month 3+6 (POM3+6) visits. Secondary outcomes included post-operative secondary surgical rates, varying from IOL refixation to endothelial keratoplasty or pars plana vitrectomy

Mean UCVA and BCVA at the preoperative visit were 1.25 ± 0.70 logMAR and 0.61 ± 0.62, respectively. Improvement in both mean UCVA and BCVA at the POM3+6 visits was seen, 0.61 ± 0.48 logMAR and 0.44 ± 0.49, respectively (p<0.001 for both). IOL refixation was performed in 3 eyes (1.8%) while post-operative endothelial keratoplasty was performed in 3 eyes (1.8%). Repeat pars plana vitrectomy was performed on 3 eyes (1.8%), while 1 eye (0.6%) needed Ahmed valve glaucoma surgery

Conventional 4-point sutured scleral fixation technique showed significant improvements in visual acuity postoperatively, while demonstrating low secondary surgical rates. Further large-scale studies assessing the safety and efficacy of this technique are warranted.
