Scleral fixated (sutured) posterior chamber intraocular lens implantation in children

Background: Optical rehabilitation of unilateral aphakia in eyes with no capsular support is problematic in pediatric patients who cannot tolerate contact lenses. Possible options include a unilateral aphakic spectacle, an anterior chamber intraocular lens (IOL), or a scleral fixated posterior chamber IOL. Of these choices the posterior chamber IOL is the most physiologic. Experience in adults shows increased complications with this technique. Objective: The objective of this study was to report the short-term results and complications of unilateral scleral fixated posterior chamber IOLs in the pediatric population. Methods: All patients with scleral fixated lenses younger than 16 years were retrospectively reviewed. Nine patients aged 12 months to 15 years underwent unilateral scleral fixated posterior chamber lens implantation using buried polypropylene fixation sutures. Follow-up averaged 24 months. Results: Postoperative visual acuity improved in all patients. Refractive goals were achieved in all but 1 patient. Complications included elevated intraocular pressure controlled with medications (1 patient), anterior uveitis (1 patient), and mild IOL decentration (1 patient). Conclusions: Although short-term visual results appear encouraging, this procedure is technically more difficult and has an increased incidence of postoperative complications when compared with secondary sulcus-fixated IOLs supported by capsular remnants. Caution should be exercised when recommending this procedure for pediatric patients because long-term risks are unknown.
