Lens Implant Options

Cataract surgery removes the cloudy, natural lens of the eye. This cloudy lens is replaced with an intraocular lens implant, or IOL. IOLs are typically acrylic material and are safe for your eye. IOLs not only replace the cloudy lens, they correct errors of the eye—nearsightedness, farsightedness, and astigmatism—to improve vision. Below is an overview of IOL technology available today.

Monofocal IOLs

Monofocal IOLsare a single focus lens. This IOL allows for correction in either far or near vision, not both. Monofocal IOLs are widely used today and improve vision for many of our patients.

Multifocal IOLs

Multifocal IOLs such as ReSTOR® and Tecnis®, can correct vision at more than one distance. These lenses can correct for near, far, and ranges in between. Patients select these lenses if they desire improved far and near vision.

Accommodating IOLs

Accommodating IOLs such as Crystalens®, also correct vision at more than one distance but uses the eye muscle to move within the eye to focus on objects, just like a natural lens. For example, to focus on a near object, the accommodating lens will move forward in the eye.

Toric IOLs

Toric IOLs such as Acrysof® and Tecnis Toric, are a single focus lens that is used to correct astigmatism of the eye. Astigmatism blurs vision due to an uneven shape of the cornea. Standard monofocal IOLs do not correct astigmatism and uncorrected astigmatism reduces vision. Many people who are nearsighted and farsighted also often have astigmatism. This lens should be considered if you want to lessen the amount of astigmatism after cataract surgery.

Each IOL has their own benefits and our cataract surgeons, will discuss them with you to ensure the most appropriate IOL is chosen for you based on your needs and lifestyle.
