Ectopia Lentis

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.

This is a single-centre, observational cohort study with the following objectives: Firstly, the investigators aim to evaluate the vision-related quality of life and mental health status in congenital ectopia lentis patients. Secondly, the investigators target to investigate the correlations between genotype and clinical phenotype in patients of congenital ectopia lentis. Thirdly, to explore the metabolic profiles in the aqueous humor (AH) of patients with congenital ectopia lentis. Lastly, this study aims to explore the longitudinal changes of ocular biological parameters and complications in patients with postoperative congenital ectopia lens in the Chinese population.
