D615L vs Zeiss 839MP: Visual Quality
Sponsor: Shanghai 10th People's Hospital
Summary
The goal of this prospective cohort study is to compare visual quality after cataract surgery in patients implanted with a new domestic trifocal intraocular lens (D615L) versus the Zeiss AT LISA tri 839MP. The main question it aims to answer is: Is the uncorrected distance, intermediate, and near visual acuity achieved with D615L non-inferior or superior to that achieved with the Zeiss 839MP? Participants diagnosed with age-related cataract will undergo phacoemulsification and receive one of the two intraocular lenses. They will attend follow-up visits where uncorrected visual acuity, defocus curves, and the VF-14 questionnaire will be assessed over a follow-up period of at least 6 months.
