Objective: To investigate the rational optical correction, visual function rehabilitation treatment methods and clinical effects of postoperative aphakic eyes in infants and children. Methods: 1. Reasonable optical correction: both eyes should use compression spherical lenses or ultra-high permeability RGP lenses (Dk value 160) that can be worn continuously overnight, while monocular children should use ultra-high permeability RGP lenses; 2. Systematic visual rehabilitation training: in addition to amblyopia training, oculomotor training such as mediation flexibility training, vergence flexibility training, reading (or gaze at target) sweeping and tracking can also be applied to 3. Visual function assessment, including eye position, gaze status, selected visual acuity and RGP lens fitting assessment, lens fitting, corneal health status (fluorescent staining), lens cleanliness and lens integrity assessment. Ultrasound was used to measure the axial length of the eye when necessary. RESULTS: Through the above treatment, the children’s visual function improved significantly, visual acuity improved, good gaze function could be restored, perceptual strabismus and nystagmus disappeared or improved significantly, and no complications related to corneal contact lenses occurred during the RGP fitting process. Conclusion: Rational optical correction and systematic visual training can significantly improve the visual skills of the children, help them to make smooth and coordinated binocular movements, enhance visual perception ability and improve visual quality.
