Intraocular Lens (IOL)


Intraocular lenses (IOLs) are the artificial lenses that are used to replace the natural lens during cataract surgery. Our cataract counselor will talk to you about the different IOL that are available. You and your doctor will make the final decision on what makes the most sense for your individual needs.



  • Traditional lens - monofocal lens – You will need glasses or contact lenses following cataract surgery to see well, possibly for both distance and near tasks.

  • Crystalens – multifocal lens – similar to wearing a progressive lens in your glasses. These lenses allow better vision in the distance, mid-range (for computer or reading music) and near vision (reading, knitting). You may still need glasses/contacts for some or all tasks.

  • Toric Lens – these lenses correct astigmatism. You will need glasses/contacts for near tasks.



Things to consider when talking with your surgeon:



  • Do I want to wear glasses for distance?

  • Do I want to wear glasses for near?

  • Do I want to be free from wearing glasses?



It’s also important to think about the things you enjoy doing to help you with your decision making:



  • Do I participate in outside activities?

  • Do I spend time knitting or crocheting?

  • Do I work on a computer all day?

  • Do I need to read music to play an instrument?

  • Do I read a lot?
