Summary

This study tests whether a custom AI chatbot can help cataract patients better understand their artificial lens choices before meeting their surgeon. About 70 adults will either get standard counseling or standard counseling plus an AI explanation. The goal is to see if the AI tool saves time, improves patient understanding, and boosts satisfaction.
