Understanding your lens options
Your surgeon will decide which lens options may be suitable for your eyes and your health.
Use this page as background reading. It can help you prepare questions for your surgeon.
Read about each lens
- Standard monofocal lensA monofocal lens gives clear vision at one distance, most often far away, with reading glasses for close work. The most common lens used in cataract surgery worldwide.
- EDOF lensA stretched focal range for distance and computer-range vision; reading glasses are often still needed for fine print.
- Full-range trifocal lensThree focal ranges — distance, computer and reading — with the greatest potential to reduce glasses dependence, and the most noticeable night-time effects to understand first.
- Light adjustable lensA lens that can be fine-tuned with light treatments after surgery, once your eye has healed — with UV-protective glasses required until the result is locked in.
