Summary

The goal of this clinical trial is to learn if an app-based vision testing (WHOeyes) combined with a questionnaire can recognize those who have to go back to the hospital, and thus replace the in-clinic 1-week review after an uncomplicated cataract surgery in people with senile cataract. It will also learn about the cost-effectiveness and environmental benefits of such remote follow-up pattern. Besides, the safety and user's satisfaction will also be evaluated. The main questions it aims to answer are: For people with uncomplicated senile cataract, does 1-week clinical follow-up replaced with remote follow-up (using a vision test app and a questionnaire) not adversely affect patients' prognosis? Can this alternative approach bring greater cost-effectiveness and environmental friendliness compared to the traditional follow-up method? Researchers will compare one-week remote follow-up to a routine clinical follow-up to see if one-week remote follow-up is feasible. Participants will: Visit the clinic to finish routine follow-up 1 day and 1 month after cataract surgery. Using app (WHOeyes) and a questionnaire at home or visit the clinic 1 week after cataract surgery.
