Summary

This study compares two types of artificial lens (intraocular lens, or IOL) used during cataract surgery. Both are extended depth-of-focus (EDOF) lenses, designed to give clear vision across a range of distances - far and intermediate - so that people depend less on glasses after surgery. The two lenses, the Tecnis PureSee and the 1stQ Comfort Z-EDOF, use different optical designs, and it is not yet known whether one provides a wider range of clear vision than the other.

Adults having cataract surgery in both eyes may take part. Each participant is randomly assigned to receive one of the two lens types, and the same lens type is implanted in both eyes. Neither the participant nor the staff measuring vision knows which lens was used until the main 6-month assessment is complete.

After surgery, participants attend check-ups at 1, 3, and 6 months. The study measures how wide a range of distances each person can see clearly, along with vision at different distances, quality of vision, side effects such as glare or halos, and overall satisfaction. The results will help doctors and patients choose between these lens types.
