Choosing the intraocular lens adapted to your needs
Besides treating cataracts and presbyopia, intraocular lenses can correct astigmatism, myopia, or hyperopia in a single procedure. It is possible to correct your astigmatism using specific intraocular lenses designed for this purpose called toric lenses.
Visual range is the distance at which an object can be seen with the unaided eye. You use your vision at mainly three distances: near, intermediate and far distance. Depending on your needs and wishes, your surgeon will select the most suited intraocular lens. Choosing the right IOL is key to fulfill your expectations for your vision and spectacle independence at certain distances.
Monofocal intraocular lenses correct far vision, Monofocal Premium intraocular lenses correct near and intermediate vision, Trifocal intraocular lenses correct near, far and intermediate vision. The choice of the intraocular lens type depends on several factors such as: your personal and family history
What are intraocular lenses?
Used for decades in cataract surgery, intraocular lenses are now an effective solution that is particularly suited to the most severe eyesight problems. Implanted inside the eye during surgery, the intraocular lenses correct the vision in the same way as glasses or contact lenses.
Life without glasses
“Trifocal lenses allow to have good vision from 3 focus points: distance vision, intermediate vision — or the one for using computers — and near vision, which is the one we use for activities like reading, sewing and crafts. ”

Intraocular lenses used today offer the latest technologies:
Flexible materials (silicone or acrylic) enabling micro-incision and surgery without any stitches
An integrated UV filter that limits the harmful effects of some light rays
An improved design of the lens rim that reduces annoying reflections and slows the process of posterior capsule opacification after surgery, also known as “secondary cataract”
Intraocular lenses are used to correct presbyopia, myopia, hyperopia, astigmatism, and cataract.
After a comprehensive assessment of your eyesight, your ophthalmologist will be able to assess the relevance and the probability of success in the surgical treatment. The choice of the surgical technique and the intraocular lens type depends on several factors such as:
The use of premium intraocular lenses does not make the surgical procedure more technically difficult.
Recover your sight with monofocal lens
Monofocal lenses allow the operated eye to see well at a single distance, mostly far vision. It works well for people who do not mind wearing glasses or who have an abnormality in one or both eyes.

With a monofocal lens, your optometrist or ophthalmologist can offer you various correction solutions:
- You will enjoy good vision at two specific distances for each separate eye, but may have difficulties combining both eyes together
- Reduced ability to judge distance, particularly when driving a vehicle (3D vision)
- Possible perception of halos around lights at night
This solution will provide you with the best quality vision for tasks requiring distance vision, such as driving during the day or night, watching TV, going to the movies, or doing sports.
However, you must wear glasses to correct your vision at an intermediate and near distance for reading a book, working on a computer, cooking, reading the time on your watch, doing your makeup, shaving or DIY. You may have to wear progressive glasses even if you do not need to wear them to see at a distance.
You can choose to correct one eye (dominant eye) for distance vision and the other (non-dominant eye) for near vision. This method provides an alternative that allows you to reduce your dependence on corrective glasses. The monovision approach requires an ability to adapt, because it implies a compromise in the quality of vision:
You might need to continue wearing glasses.
Corrective glasses may be required to equalize the vision in both eyes for precision tasks or to improve your comfort for prolonged tasks, such as driving at night, working on a computer, or reading small print.
You can correct your astigmatism with toric lenses.
Astigmatism is an optical defect likely to be corrected in cataract surgery. It is necessary to correct the astigmatism induced by the cornea, because a possible astigmatism of crystalline origin disappears with the withdrawal of the crystalline lens during the intervention. Implants that correct astigmatism are called "toric IOLs".
Outcomes are the same as a monofocal IOL, including regular astigmatism correction.

To better respond to modern lifestyles of today’s patients, the Premium monofocal IOL (Polynomial technology) is now available. This unique IOL design matches a monofocal IOL’s high quality standard for far vision, and additionally provides partial intermediate visual improvement* bringing more freedom in your life.
Your will recover your vision rapidly.
Eyesight begins to recover from the first day after the surgery and a total recovery may take several weeks.
After the procedure, some patients might experience disturbance from lights, especially at night. These disturbances diminish significantly after a few months, due to the phenomenon of brain neuroadaptation.
This surgery is the most common procedure performed in the world.
It enjoys a complete success rate in 95% of cases.3 However, as with any intervention, one can never completely exclude a complication. The most severe complication that may occur during cataract surgery is an intraocular infection. The frequency of this type of complication is 1 in 2,500 cases. In 4 cases out of 1,000, difficulties can occur during surgery, causing retinal detachment. This then will require additional surgery
In a third of patients, the lens capsule can become opaque again a few months or even years after surgery. This phenomenon is called a “secondary cataract” or “posterior capsule opacification.” The treatment involves making an opening in the opaque posterior capsule (capsulotomy) using a YAG laser. This will restore the eyesight by the next day after laser treatment.
Getting rid of glasses with trifocal lens
The trifocal intraocular lens has three different focal points offering a full extended range of vision.
This technology is designed to provide good vision at all distances: near vision (40 cm), intermediate vision (60-80 cm) and far vision. This intermediate distance is increasingly used for instance, for working on a computer, tablet, or smartphone.

You could decrease the burden of your glasses with a trifocal lens.
The trifocal intraocular lens is a solution for cataract patients with or without presbyopia who want to reduce the burden of their glasses. It can also correct astigmatism, myopia, or hyperopia in a single procedure, which eliminates the need to wear glasses.
- 0of patients with a trifocal lens implant get rid of their glasses or contact lenses for good.*
- 0of patients would recommend it to their family and friends.*

The choice of the intraocular lens must consider the existence of associated ocular or general pathologies. The presence of glaucoma, diabetic retinopathy, retinal degeneration is likely to restrict the range of options for choosing an intraocular lens.
