Summary

This is a multi-centre, open-label, parallel-group randomized controlled trial with the following objectives: Firstly, the investigators aim to evaluate the efficacy of web-based visual and perceptual training therapy on visual function in children with postoperative congenital ectopia lentis. Secondly, the investigators target to investigate the in stereoacuity, quality of life scores, and treatment compliance following visual and perceptual training intervention. Thirdly, to explore the safety profile of visual and perceptual training therapy software in this specific patient population. Lastly, this study aims to provide evidence-based recommendations for visual rehabilitation training strategies in children with postoperative congenital ectopia lentis in the Chinese population.
