Clinical trials

The purpose of this study is to evaluate the long-term visual outcome of the cataract surgery using a large-scale and comprehensive database of pediatric cataract participants, including congenital and traumatic cataract. The investigators will further investigate into the various genetic and environmental factors that may contribute to the pathogenesis of pediatric cataract.

The goal of this clinical trial is to learn if transcranial magnetic stimulation (TMS) can improve the visual outcomes in patients with visual impairment. The main question it aims to answer is: • Does TMS improve the visual outcome in patients who suffer from visual impairment? Researchers will compare TMS to the control group who will not receive effective TMS treatment) to see if TMS works to improve the visual outcomes of the patients. Participants will * Undergo TMS treatment or no effective TMS for consecutive 5 days. * Visit the clinic once every 2 weeks for checkups and tests.

The purpose of this study is to evaluate the visual outcome of the cataract surgery, including best uncorrected and corrected visual acuity, spherical equivalent, wavefront aberration and other measurements.
