An intraocular lens (IOL) is an artificial lens that’s implanted during cataract surgery. Recent advances have been so significant that new-generation lenses could allow you to see well at all distances without the help of glasses, bifocals or reading glasses.
The following are the three primary types of lenses currently available and what each is designed to do for your vision:
- Monofocal lenses such as the AcrySof® IQ IOL have one point of focus and can usually give you clear distance vision. While distance vision is improved, most patients still need to wear glasses for certain tasks, such as reading or working at a computer.
- Multifocal lenses such as the AcrySof® ReSTOR® IOL are designed to replace cataracts and correct presbyopia at the same time. Their goal is to give you a full range of clear vision, near to far, and everywhere in between.
- Astigmatism-correcting lenses such as the AcrySof® Toric IOL are for patients with existing corneal astigmatism. Similar to monofocal lenses, these lenses usually give patients quality distance vision with less dependence on glasses. Most patients will still need to wear glasses for tasks such as reading or working at a computer.
The correct lens for you will depend on your eyes and your desire to be glasses-free. Your doctor will review your options and explain what you can expect from each one. Cataracts can dramatically affect everything you see and do. But they don’t have to. With a simple procedure, you can lift the fog and get back to seeing what you love. Colors can appear rich and vibrant, and everything you look at can be in clear focus.
