Comparing the outcome of intraocular lens implantation with or without posterior optic capture in pediatric cataract surgery

Abstract

Purpose To evaluate the outcome of intraocular lens (IOL) implantation with posterior optic capture versus in-the-bag implantation in pediatric cataract surgery. Setting Ain Shams University Hospital and Research Institute of Ophthalmology. Design It is a prospective, comparative clinical study. Patients and methods Thirty eyes with developmental cataract underwent primary cataract extraction and IOL implantation of hydrophobic acrylic multipiece Sensar IOL AR40e. In all cases, anterior and posterior continuous curvilinear capsulorrhexis, lens aspiration, and anterior vitrectomy were performed. IOL was implanted in the ciliary sulcus, and the optic was captured in both anterior and posterior capsulorrhexis in group A (15 eyes) and implanted in the bag without capture in group B (15 eyes). Visual acuity, visual axis opacification, red reflex, intraocular pressure, centration, and complications were all assessed. Results The mean age of children was 5.3±2.93 years. At 6 months of follow-up, the mean postoperative corrected distant visual acuity was 0.69±0.19 and 0.65±0.23 in groups A and B, respectively. The mean clear central zone was 4.29±0.24 and 3.6±0.55 mm in groups A and B, respectively (P=0.001). The mean IOL decentration measured in mm was 1.61±1.17 and 0.86±0.28 SD in groups A and B, respectively (P=0.003). There were no postoperative complications in all cases. Conclusion Placement of IOL haptics in the ciliary sulcus while capturing the optic through the posterior continuous curvilinear capsulorrhexis provides more central clarity of the visual axis, however IOL decentration was more common.
