There is a wide range of replacement lenses available to cataract patients, each offering different advantages for your post-surgery vision. The most effective lens depends on each patient’s individual preferences and goals for their vision. The latest lenses help eliminate the need for glasses or contact lenses after cataract surgery; providing convenient, effective results for your specific vision requirements.
Artificial intraocular lenses (IOLs) are implanted in the eye to replace the natural lens for patients with cataracts, presbyopia or refractive errors. Until recently, IOLs were only available to correct distance vision. These monofocal lenses helped improve distance vision after cataract surgery, but patients still needed glasses or contact lenses for near vision activities like reading and playing cards. Now, advancements in technology have produced Trifocal and Extended Depth of Focus IOLs that allow patients to see clearly at more distances — near, far and many distances in between. Multifocal IOLs such as TECNIS Symfony®, TECNIS Synergy™, and IQ PanOptix® use diffractive technology to preserve distance vision and correct presbyopia so that patients can enjoy freedom from glasses! Extended depth of focus IOLs such as TECNIS Eyhance®, IQ Vivity® are the newest technologies on the market that use refractive technology in order to provide distance vision and functional middle vision (e.g. tablet, dashboard).

Eye on Lens Technology
Advances in lens technology mean improvement in the quality and variety of lenses you may choose from, customized to your lifestyle. Our lens options range from standard lenses that are generally covered by OHIP to upgraded “Lifestyle PREMIUM” lenses. Your NTEC doctor can help you decide which lens is the best choice for your needs.
LIFESTYLE Lens Implant Options: See near, far and in between
To choose the right lens for your particular lifestyle and vision needs, your doctor will perform a series of tests to map your eye. The basic tests are covered by OHIP, but more specialized tests require an additional fee.
• A basic spherical monofocal lens provides distance vision and is covered by OHIP. You may or may not still need distance glasses to see more clearly.
• An aspheric monofocal lens* is designed to provide improved image quality by reducing spherical aberrations. It will provide crisper, clearer images with enhanced contrast and improved low light vision.
• A toric monofocal lens* will reduce the need to wear distance glasses in patients with astigmatism (optically oval eyes).
• A extended range of focus lens** will reduce the need for distance and middle (e.g. tablet) glasses, without compromising distance vision. These are one of the latest advancements in lens technology.
• A trifocal lens** will reduce the need to wear reading glasses. It is designed to provide vision at multiple distances – near, intermediate and far. These are one of the latest advancements in lens technology.
While current technology is able to provide more range of focus, these lenses cannot replicate the amazing range of vision you had when you were 20 years old. Sometimes glasses for near are still required.
* There is an additional cost to the patient for this lens. See separate pricing guide for additional information.
** There are several options for this type of lens that can be specifically suited to your lifestyle and visual desires. Be sure to ask which lens would be best for you.
TECNIS® Monofocal IOL
The TECNIS® Monofocal IOL is a high-quality engineered lens. This monofocal lens is safe and efficient while simultaneously providing optical excellence. The lens provides maximized functionality, implementing sharper overall vision.
AcrySof™ IQ Intraocular Lens
The Acrysof™ IQ lens provides sharp distance vision as well as filters harmful blue light which not only protects the retina but enhances vision to give vibrant, natural colours.
TECNIS® Toric IOL
The TECNIS® Toric lens is a high-quality lens that provides clear distance vision while correcting a patient’s corneal astigmatism to eliminate the need for distance glasses.
AcrySof™ IQ Toric IOL
The AcrySof™ IQ Toric IOL corrects for corneal astigmatism to provide sharp distance vision. Like other AcrySof IQ IOLs, this lens filters out blue light.
Extended Depth of Focus Lens
Multifocal and Extended Depth of Focus IOLs
TECNIS® Multifocal IOL
Cataract surgery, which replaces the eye’s cloudy lens with an artificial clear intraocular lens or IOL is the most common operation in Canada. More than half of adults over age 65 have some degree of cataract development. People aged 65 and older are also more likely to be involved in car crashes than people in their 30s, 40s, and 50s. Now an innovative night vision-enhancing IOL can help elderly drivers with cataracts avoid accidents.
The Tecnis® IOL was designed to provide cataract surgery patients with high-quality vision comparable to that of young people. Its main concern is improving safety with vision correction. It is meant to improve functional vision – the ability to see objects in varying light conditions – especially at night and twilight and in rain, snow, and fog. This means improved night vision and reduction of spherical aberrations, an undesirable scattering of light that is a common side effect of cataract surgery.
TECNIS® Symfony Extended Range IOL
The latest addition to the TECNIS® family of IOLs offers new optical technology for providing an extended range of vision.
Traditional IOL solutions for treating presbyopia include Multifocals and Trifocals, which work on the principle of simultaneous vision by splitting light into multiple distinct foci, and Accommodative IOLs, which change in shape and power when the ciliary muscle contracts.
Traditionally with these technologies, the correction of presbyopia is commonly thought of in terms of the distinct distance for which functional vision is provided.
AcrySof™(R) IQ PanOptix®
The AcrySof(R) IQ PanOptix® is a multifocal correcting intraocular lens (IOL) for patients with presbyopia undergoing cataract surgery. This is a lens option for patients who are looking to correct all levels of vision with a single lens.
With optimum visibility in all lighting conditions and reliable UV and blue light filters, the PanOptix® lens truly allows for flexible transitioning in all day-to-day functions, such as using a computer, outdoor activities, or reading a newspaper.
Alcon AcrySof® IQ Vivity®
The Alcon AcrySof® IQ Vivity® lens provides patients with high-quality distance and intermediate vision, as well as some functional near vision. This is achieved with newly available X-Wave™ technology, a non-diffractive lens that uses available light for continuous extended vision range.
This lens can reduce the need for glasses following cataract surgery. For patients with astigmatism, the Vivity lens is available as a toric IOL, which allows astigmatism to be corrected during the cataract procedure.
Patients using Vivity reported low levels of starbursts, halos, and glare very close to a monofocal lens implant, allowing physicians to implant this lens in patients with retina and other visual conditions.
TECNIS Synergy IOL
Refractive correction services that are offered during cataract surgery can include special-feature intraocular lenses like multifocal and accommodating IOLs, femtosecond laser-assisted cataract surgery, and other specialized diagnostics. These services are an additional cost to patients because they are not deemed medically necessary. Newer innovations for cataract surgery aim to enhance refractive outcomes for patients who are hoping to be independent of glasses or contacts lenses but at a financial cost.
