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 contacts 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 severe 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 multifocal IOLs that allow patients to see clearly at all distances — near, far and many distances in between. Multifocal IOLs such as TECNIS Symfony®, Tecnis® Multifocal, PanOptix® Toric intraocular lens, Lentis Mplus X IOL, and Crystalens® preserve distance vision and correct presbyopia so cataract surgery patients and patients seeking treatment for presbyopia alone can enjoy clear sight without relying on glasses. The procedure to replace a patient’s natural lens with a multifocal IOL is the same as that used in cataract surgery.
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 that may be partially covered by OHIP. 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
It’s critically important to get an accurate picture of your eye to obtain the best possible vision following your surgery. To choose the correct lens for your particular lifestyle and vision needs, your doctor will perform a series of simple tests to map your eye. Most tests are covered by OHIP, but some more specialized tests require an additional fee. Together, you and your doctor will determine the most appropriate level of testing for your needs.
• A basic monofocal spherical lens provides clear distance vision and is provided at no additional cost.
• An aspheric 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 lens* will reduce the need to wear distance glasses in patients with astigmatism (optically oval eyes).
• A multifocal lens** will reduce the need to wear reading glasses. It is designed to provide good focus on objects at multiple distances-near, intermediate and far. These are one of the latest advancements in lens technology.
While current technology is able to provide some 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.

AcrySof™ IQ Intraocular Lens
As we age, the risk of developing cataracts, as well as other visual disorders significantly increases. Many patients with cataracts also suffer from spherical aberrations, which are irregularities within the refractive surface of the eye that can cause blurriness, halos, double vision and poor night vision. There are several artificial replacements, known as intraocular lenses (IOLs), available to be used during cataract surgery, including the advanced AcrySof IQ IOL.
In addition to relieving the symptoms of cataracts, the Acrysof IQ lens also improves vision by correcting spherical aberrations that become more and more common as we age. This lens offers patients enhanced clarity and improves the overall image quality. The Acrysof IQ IOL also filters harmful blue light which not only protects the retina but enhances vision to give vibrant, natural colours. With this lens, patients can see the works as good as or even better than they did when they were younger.
TECNIS® Toric IOL
The TECNIS® Toric lens is a high-quality, sustainable intraocular lens designed for patients who are looking for seamless vision correction. The TECNIS® IOL provides individuals with stunning visual performance in all conditions and low-light situations, such as driving at night, with no glistening effects or visual impairment.
By improving any spherical inconsistencies in the eye, the lens provides astigmatism correction alongside clear, beautiful visual acuity. Rid yourself of the need for glasses and still maintain the clear vision you desire with the TECNIS® IOL.
AcrySof™ IQ Toric IOL
Until recently, patients with astigmatism were forced to rely upon glasses or contact lenses even after their cataract surgery, as the replacement IOL did not correct corneal astigmatism. Now, patients can benefit from the AcrySof IQ Toric IOL, an advanced lens that simultaneously removes any pre-existing astigmatism of up to 3 diopters at the same time that the cloudy lenses is removed.
After implantation of the AcrySof IQ Toric lens, patients can enjoy a higher quality of life as they are able to drive, watch television, play sports and enjoy other activities without the hassle of glasses or contacts. This lens is the only solution available to correct both cataract and astigmatism vision problems. Like the other AcrySof IQ IOLs, the Toric lens blocks ultraviolet light and features blue-light filter technology that protects the retina and ensures brilliant, colorful vision after surgery.
FineVision Toric IOL
FineVision is also available with the additional toric correction for astigmatism. FineVision Toric can potentially correct in one surgery presbyopia, astigmatism and myopia or hyperopia, and thus eliminate the need for glasses.
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.
Crystalens® is a new replacement lens (IOL) that works naturally with muscles in the eye to retain the eye’s ability to “accommodate” – to shift focus between nearby and distant objects. With older IOLs, patients lose this ability and require corrective eyewear to see clearly at near and intermediate distances.
Unlike rigid lenses, the flexible silicone Crystalens features innovative hinges that allow it to move with the eye’s muscles and accommodate seamlessly, thereby reducing or eliminating the need for vision correction. The Crystalens is implanted using the same, nearly risk-free cataract surgery techniques as with other IOLs.
AcrySof™(R) IQ PanOptix®
The AcrySof(R) IQ PanOptix® is a multifocal correcting intraocular lens (IOL) for patients with pre-existing corneal astigmatism and presbyopia undergoing cataract surgery. This is a lens option for astigmatic patients who are looking to flawlessly 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.
FineVision Trifocal Intraocular Lens
FineVision, the first diffractive trifocal IOL, provides optimal vision at all distances without glasses. FineVision is a trifocal intraocular lens that features a series of rings which diffract light to provide — far, intermediate and near vision, lending to the name FineVision.
FineVision features an innovative trifocal structure designed to significantly improve performance for intermediate vision.
The design of FineVision is different to multifocal or bifocal glasses. You don’t have to worry about moving your head to see clearly or even walking downstairs, as the lens is implanted in the eye. Many patients implanted with FineVision don’t need to wear glasses for everyday tasks such as driving, reading the car speedometer or even using their smartphone.
Lentis Mplus X IOL
The Lentis Mplus X IOL is a premium multifocal IOL providing correction for near, intermediate, and distance vision. This IOL provides excellent contrast sensitivity, and helps to minimize the occurrence of halos and glare as a result of cataract surgery.
The Lentis Mplux X IOL can help to reduce dependence on glasses and correct common refractive errors like presbyopia, myopia, hyperopia, and astigmatism. With this IOL. patients are able to easily transition from activity to activity, such as computer work, driving, golfing, etc.!
TECNIS® Symfony Toric IOL
The TECNIS® Symfony Toric lens rids the effects of presbyopia and helps to correct astigmatism, so patients can be empowered to see clearly across a full range of vision with no disparity between near and far.
By increasing the depth of field, the TECNIS® Symfony Toric IOL allows patients to experience visual acuity and uninterrupted vision at any distance. This means that you can drive, play golf, read the newspaper, or use a computer and experience consistent clear vision throughout. The state-of-the-art technology of the TECNIS® Symfony lens provides high image contrast and long-term success in vision correction.
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.
