Abstract
Purpose
This study aims to report long-term outcomes of secondary intraocular lens (IOL) implantation after early cataract surgery in children.
Methods
This is a retrospective case series that included children undergoing secondary IOL implantation. The patients had either in-the-bag (ITB) or sulcus implantation; alternative methods of IOL fixation were excluded. Single-piece acrylic IOL was used for ITB and 3-piece acrylic or PMMA IOL for sulcus implantation. The visual acuity outcomes and rate of complications at the last follow-up visit were evaluated.
Results
One hundred six eyes (70 patients) were analyzed. The mean follow-up was 5.5 ± 3.8 years. Sixty-two eyes (58.5%) had ITB; 44 eyes (41.5%) had sulcus IOL. All but 3 eyes (97.2%) showed stable or improvement in visual acuity. Early inflammation > grade 2 + was noted with sulcus IOL (84% vs 34%, p = 0.01); late inflammation requiring vitrectomy occurred in one eye with sulcus IOL. Mild decentration was seen in 2 eyes with sulcus IOL; one additional subluxed sulcus IOL was exchanged. Sixteen out of 106 eyes (16%) had glaucoma. Eyes that developed glaucoma had early primary surgery (mean, 0.2 years, p < 0.001, significant); there was no difference in glaucoma rates based on implantation site.
Conclusion
Early postoperative inflammation is higher in eyes with sulcus implantation, but good visual acuity outcomes are noted after secondary IOL implantation in children. Glaucoma is the main complication that requires close monitoring and is associated with early age at primary surgery.
