Rigid Gas-Permeable Contact Lens for Visual Rehabilitation in Children Younger Than 12 Years With Penetrative Ocular Trauma.

Abstract

To observe the clinical outcomes of visual rehabilitation using rigid gas-permeable contact lenses (RGPCLs) after penetrative ocular trauma in children younger than 12 years in China. Patients younger than 12 years with penetrative ocular trauma fitted with an RGPCL for visual rehabilitation from 2017 to 2021 were included. In the case cohort, the best-corrected visual acuity (BCVA) with spectacles was measured when the RGPCL was fitted, and the initial BCVA with RGPCL, and the BCVA at the last visit were compared. Fifteen patients, aged 4 to 12 (mean 8.0±2.7) years, who wore an RGPCL for 7 to 53 (mean 20.3±15.7) months, were included. The BCVA was log of minimal angle of resolution 0.4 (0.2-0.7) with spectacles and 0.1 (0.1-0.2) for RGPCL at the initial visit, and 0.0 (0.0-0.1) for BCVA at the last visit, with a statistically significant difference between the three comparisons ( P <0.001). Six of the 15 (40%) children abandoned wearing RGPCL because of discomfort and lens rejection (n=3, 50%), lens loss and inability to replace broken lens because of travel distances and epidemics (n=2, 33%), and cost (n=1, 17%). Although application is complicated and initial wearing comfort is poor, an RGPCL is still a beneficial, safe tool for postoperative visual rehabilitation in children with open ocular trauma.
