Comparison of Two Intraocular Lens Implantation Techniques in Pediatric Cataract Surgery in Terms of Postoperative Complications.

Abstract

Background:Pediatric cataract surgery differs substantially from adult cataract surgery. Numerous studies have focused on reducing the development of postoperative complications.Aims:To compare two intraocular lens implantation techniques used in pediatric cataract surgery in terms of postoperative complications.Study Design:Case-control study.Methods:Patients who underwent pediatric cataract surgery and intraocular lens implantation between 2008 and 2016 were evaluated in this retrospective study. Patients aged 3-15 years with unilateral or bilateral cataract and without corneal pathology were included in the study. The patients were categorized into the following two groups: those who underwent posterior capsulorhexis and anterior vitrectomy using in-the-bag intraocular lens implantation (group 1) and those who underwent posterior capsulorhexis and intraocular lens implantation with the optic fixed behind the posterior capsulorhexis (group 2). Rates of postoperative visual axis opacification and complications (glaucoma, posterior synechiae, uveitic reaction, and intraocular lens decentration) were evaluated in these groups. The implanted intraocular lenses were either monoblock (AcrySof SN60AT intraocular lens), triple-piece (AcrySof MA60BM intraocular lens) foldable hydrophobic acrylic lenses, or multifocal lenses (AcrySof IQ ReSTOR).Results:This retrospective study included 52 eyes of 37 patients. Group 1 comprised 26 eyes of 20 patients and group 2 comprised 26 eyes of 17 patients. During the follow-up, visual axis opacification was observed in two patients in group 1 but no patients in group 2. Regarding postoperative complications, there was no uveitic reaction, posterior synechiae, or intraocular lens decentration in either group. There was no significant difference between the groups in terms of the postoperative complications (p>0.05).Conclusion:There was no significant difference between in-the-bag intraocular lens implantation after posterior capsulorhexis and intraocular lens optic capture through posterior capsulorhexis in terms of the complications.
