Summary

This study tested two different trifocal lens implants used during cataract surgery to see which one gives better vision. 87 people who needed cataract surgery in both eyes received one type of lens in each eye. The main goal was to measure how clearly they could see letters on a chart in bright light. Results help doctors choose the best lens for their patients.
