Cataract Surgery Experience
Conditions
Brief summary
The goal of this clinical trial is to learn if transcranial magnetic stimulation (TMS) can improve the visual outcomes in patients after cataract surgery. The main question it aims to answer is: • Does TMS improve the visual outcome in patients after cataract surgery? Researchers will compare TMS to the sham-controlled treatment (exposure to recorded sounds of pulses without real magnetic stimulation) to see if TMS works to improve the visual outcomes of patients after cataract surgery. Participants will * Undergo TMS treatment or a sham-controlled treatment for consecutive 5 days. * Visit the clinic once every 2 weeks for checkups and tests.
Interventions
TMS treatment in this study indicates a non-invasive procedure called transcranial magnetic simulation (TMS) on visual cortex. The treatment intensity is set as 80% of the threshold of each participant. The treatment will be conducted every day for consecutive 5 days.
The control treatment is a sham-controlled procedure, in which participants will be exposed to the recorded sounds of TMS pulses but without real magnetic stimulation.
