Spectacle Adherence Among Four-Year-Old Children in the Infant Aphakia Treatment Study

Abstract

Purpose: To evaluate spectacle adherence with impact resistant lenses among 4-year-old children after unilateral cataract surgery in the Infant Aphakia Treatment Study. Design:Retrospective cohort analysis of randomized clinical trial data. Methods:Setting: Multicenter.Patients: 114 children randomized to contact lens correction or intraocular lens implantation following unilateral cataract surgery during infancy.Intervention: One week diaries completed annually and retrospective telephone interviews conducted every 3 months to age 5 years to assess spectacle adherence with impact resistant lenses using. Visual acuity was assessed by a traveling examiner at age 4.5 years. Main Outcome Measures:Spectacle adherence between ages 4 to 5 years. Results:Children with 20/40 or better vision in their treated eye were more likely to wear spectacles ≥80% of their waking hours than children with vision worse than 20/40 (66% vs 42%, p=0.034). Reported adherence to spectacle wear correlated with reported patching (r=0.30, p=0.002). Spectacle adherence did not correlate with gender, type of healthcare insurance or the refractive error in the treated or fellow eye. Seven patients with reduced vision in their treated eye reported <10% spectacle adherence.

“…However, if a primary intraocular lens is not implanted, the resulting amblyopia needs to be treated as soon as possible to facilitate visual rehabilitation. This can be achieved with aphakic glasses or contact lenses (silicone elastomeric lenses or rigid gas permeable lenses) (6)(7)(8).…”
