Step 1
First, know the three zones
An IOL is the clear artificial lens placed in your eye during cataract surgery. Different IOLs cover different everyday distances:
- Far — Road, TV, outdoors
- Mid — Laptop, dashboard
- Near — Books, phone, print
Premium lenses cover more zones. Your surgeon matches the choice to your eye health — not only your wishlist.

Toric can be added to suitable lenses when you have astigmatism — it corrects warped blur, not the Far / Mid / Near pattern itself.

This guide is for understanding. Your doctor will check cornea, retina, and lifestyle — then recommend the safest lens for you.
