Evidence comparing rigid gas-permeable contact lenses (RGPCLs) vs spectacles for rehabilitation is needed. To compare the use of RGPCLs vs continued spectacle wear for improving visual outcomes for children after PCG surgery. This randomized clinical trial was conducted at Zhongshan Ophthalmic Center, a tertiary referral center in Guangzhou, China, from April 21, 2022, to August 21, 2023. Participants comprised 56 children (aged 4-15 years) with surgically managed PCG and poor spectacle response. Data were analyzed from October 11, 2023, to March 21, 2024. RGPCLs (n = 29) vs spectacles (n = 27) for 12 months, plus standardized amblyopia patching. The primary outcome was change in worse-eye best-corrected visual acuity (BCVA) at 12 months measured by the Early Treatment Diabetic Retinopathy Study chart with tumbling-E optotypes with children wearing their current best refractive correction. Secondary outcomes included contrast sensitivity function and near stereoacuity. Among 56 (of a total of 83 screened participants) randomized participants, 48 (85.7%) completed at least 1 follow-up visit and were included in the primary analysis. Baseline demographic and ocular characteristics for the RGPCL group vs the spectacles group included a mean (SD) age of 7.7 (2.7) vs 7.2 (3.2) years, 13 (54.2%) vs 14 (58.3%) male, and 11 (45.8%) vs 10 (41.7%) female.

These findings suggest that RGPCLs provided superior visual acuity and contrast sensitivity improvement vs continued spectacle wear for children after PCG surgery. These findings support using RGPCLs for children undergoing PCG surgery, including those with worse baseline visual acuity or poor spectacle response.
