Outcomes of secondary sulcus intraocular lens implantation in unilateral anterior persistent fetal vasculature

Abstract:

AIM: To evaluate the surgical results of sulcus intraocular lens (IOL) implantation in children with unilateral anterior persistent fetal vasculature (PFV) underwent primary vitrectomy combined with lensectomy and preservation of the peripheral anterior capsule. METHODS: Twenty-two eyes of 22 children with unilateral anterior PFV who underwent sulcus secondary IOL implantation were analyzed. Main outcome measures were preoperative and postoperative visual acuity, and complications both intraoperatively and postoperatively. RESULTS: Review of 22 consecutive patients identified best-corrected visual acuity (BCVA) improvement from 1.37±0.84 to 0.73±0.57 logarithm of the minimal angle of resolution (logMAR) after IOL implantation (P<0.001) with a mean follow-up was 16.55±5.86mo. Average age at secondary IOL implantation was 41.05±15.41mo. Three eyes (13.64%) achieved BCVA of 0.3 logMAR at the final visit. Transient intraocular pressure rise (4 eyes; 18.18%), postoperative increased inflammation (3 eyes; 13.64%) and postoperative hypotony (2 eyes; 9.09%) were common complications. CONCLUSION: Properly preservation of the anterior lens capsule during the primary surgery facilitated secondary sulcus IOL implantation in pediatric patients with anterior PFV, with favorable postoperative visual outcomes and compatible percentage of complications.
