What are intraocular lenses (IOLs)?

An intraocular lens implant(or IOL) is a tiny, artificial lens for the eye. It replaces the eye's natural lens that is removed during cataract surgery or refractive lens exchange (RLE). The lens bends (refracts) light rays that enter the eye, helping you to see clearly.

 

At Assil Guar Eye Institute, our cataract lens options offer our refractive and cataract patients a full range of vision options. These lenses can significantly improve vision and sometimes even eliminate the need for glasses. 

How many different IOLs are there on the market?

 

Many! There are now over 60 companies making Intraocular Lenses worldwide. The leaders in the market include Johnson & Johnson, Bausch Healthcare, Alcon, Ophtec, Lenstec, and RxSight, to name just a few. 

 

Since Assil Gaur Eye Institute is one of the most advanced ophthalmological practices in the nation and a leader in cataract surgery, we support many different IOLs to achieve the very best vision correction across our entire patient population.

 

How do I choose the right IOL? 

Selecting the right intraocular lens (IOL) for your specific needs is a crucial decision, and we understand it can be overwhelming with so many options on the market. But at Assil Gaur Eye Institute, you never need to worry about making the wrong decision as we are by your side during your entire journey. You will have the best choice based on your needs, lifestyle, insurance, potential complications, etc.

 

Remember, there is no one-size-fits-all answer, and the best premium IOL lens for you will depend on your specific needs and lifestyle. As your ophthalmologists, we are the best resource to guide you to the right type of lens, as we are familiar with your eye health and all the available options for clear vision.

 

Our cataract patients trust our expertise and never hesitate to ask questions; we are here to help you make the best decision for your vision.

 

Do different types of IOLs correct different types of vision problems? 

Different types of intraocular lenses (IOLs) are designed to address various vision problems. Some provide vision at a single focus, usually distance vision. Others have multiple zones of vision correction to help you see at both distance and near. Some are designed to work with your eye’s muscles to allow focusing at multiple distances. At the same time, others are made especially for people with astigmatism. 

 

For the rest of this article, we will explain the different IOL options available at AGEI and how they correct our patient’s vision.

 

Monofocal IOL Lens 

Monofocal lens is the most common IOL and has been used for decades. Monofocal lenses provide the best possible vision at just one distance, near, medium, or far distances. Monofocal lenses are usually covered by insurance and Medicare.

 

Monofocal lenses have only one focal point and help you see clearly at one specific range, such as near, medium, or far distances. Sometimes, one eye is adjusted for close viewing and the other for distance, a technique known as monovision. This allows you to see well at various ranges once your brain gets used to switching between eyes.

 

People who don't mind wearing reading glasses might prefer these lenses. They can be especially helpful for those with eye conditions like keratoconus or macular degeneration.

 

The Monofocal IOL lens that AGEI supports includes Tecnis Monofocal LensTM, Bausch + Lomb Envista IOLTM, and Artisan Aphakic IOLTM.

 

Multifocal IOL lens

Multifocal IOLs let you see objects clearly at different distances, similar to bifocal or trifocal glasses. They're helpful for everyday activities like reading or computer work and can reduce the need for glasses (presbyopia-correcting). Multifocal IOLs can eliminate the need for eyeglasses.

 

They usually require an adjustment period because the brain must learn to select the correct vision information for near or distant objects.

 

However, Multifocal IOL lenses might cause glare or halos around lights at night. If you drive a lot at night, you might prefer monofocal IOLs with a single focus point.

 

The Multifocal IOL lenses Assil Gaur Eye Institute supports include Tecnis Multifocal IOLTM, Tecnis Eyhance IOLTM, Alcon Vivity IOLTM, Lenstec SBL-3TM, Tecnis Synergy IOLTM and Tecnis Odyssey IOLTM.

 

Toric IOL Lens

Toric contact lenses are made specifically for people who need astigmatism correction, a condition where the cornea's shape causes blurry vision. Unlike regular contact lenses, toric lenses correct astigmatism problems, allowing you to see clearly and comfortably.

 

The Toric IOL lenses Assil Gaur Eye Institute supports include AcrySof PanOptix Toric IOLTM, Tecnis ToricTMII, enVista ToricTM, Tecnis Eyhance ToricTM, Synergy ToricTM, Tecnis OdysseyTM and Vivity ToricTM.

 

Extended Depth-of-Focus (EDOF) lens

Extended depth-of-focus (EDOF) lenses are different from multifocal lenses. Instead of having several focus areas, they have one continuous range of vision, helping you see far away (distance vision) and at middle distances (intermediate vision) when using a computer. However, you might still need to wear glasses for near-vision (close-up) activities like reading (presbyopia-correcting).

 

The EDOF premium lens that AGEI supports includes IC-Apthera IOLTM, PanOptix Trifocal LensTM, and Tecnis Symfony OptiBlue IOLTM.

 

Accommodative IOL lens 

Accommodative lenses work like the eye's natural lens, allowing it to change focus between near and far objects. This mimics how a young eye functions, and the goal is to let you see clearly at different distances without needing glasses for most activities (presbyopia-correcting).

 

The Accommodative IOL lens that AGEI includes Crystalens IOLTM.

 

Light-adjustable lenses (LALs)? 

Light-adjustable premium lenses are a fresh invention in eye care. Unlike other lens options, these can be precisely adjusted by our eye doctor after your lens replacement surgery.

 

How? Through a few easy, painless UV light treatments spaced over several days. This process tailors your lens to your specific needs, helping you see almost exactly how you want. But, since these are a kind of single-focus lens, you'll still need glasses for reading or driving.

 

The LAL premium lens that AGEI supports includes RxSight Light Adjustable LensTM

Intraocular lens FAQs

Can IOL implants help with farsightedness?

Yes, IOLs can fix nearsightedness (myopia), farsightedness, astigmatism, and presbyopia.

What are IOLs made of?

Most IOLs are made of acrylic, silicone, or other plastic compositions. They are also coated with a special material to help protect your eye from harmful UV rays.

Is a phakic lens an IOL? 

No, a phakic lens is not an IOL. While both are medical implants placed inside the eye to improve vision, they serve different purposes and are used in different types of patients.

 

An Intraocular Lens (IOL) is typically used to replace the eye's natural lens during cataract eye surgery or to correct significant refractive errors in a procedure known as refractive lens exchange. A phakic lens, on the other hand, is inserted into the eye without removing the natural lens

Can an IOL move out of position after surgery? 

Although relatively rare, an intraocular lens (IOL) can move out of position after surgery. This is known as lens dislocation or lens subluxation.
