A wide range of replacement lenses are available to cataract patients, each offering different advantages for post-surgery vision. The most effective lens to use depends on the patient’s individual preferences and goals for their vision. The lenses eliminate the need for glasses or contacts after cataract surgery, providing most patients with convenient, effective results for their specific vision conditions. Your eye doctor will discuss your options, including AcrySof™ IQ Vivity™ Extended Vision IOLs and other IOLs. Discuss all of your IOL options with your eye doctor.
A monofocal IOL is designed to provide clear distance vision. This means you will usually be able to see objects far away, but there is still a small chance that you may need glasses for distance vision especially if you have corneal astigmatism. You will most likely need glasses for near vision activities such as reading, writing, and sewing, as well as intermediate vision activities such as applying makeup or shaving and working on a computer. These lenses do not correct for corneal astigmatism.
Multifocal IOLs allow for clear distance vision (e.g., for watching children playing in the backyard). The design of the IOL also allows for better near (reading) and intermediate (computer work) vision than a monofocal lens would provide. Different multifocal IOLs have different optical strengths for near vision. There is a chance you may still need glasses for distance, intermediate, and/or near vision. These lenses do not correct for corneal astigmatism.
The AcrySof™ IQ Vivity™ Extended Vision IOLs are another IOL option that has the same basic shape and identical materials as many other Alcon AcrySof™ monofocal and monofocal toric IOLs. Like a monofocal lens, the purpose of the AcrySof™ IQ Vivity™ Extended Vision IOL is to focus images clearly onto the back of your eye (retina) to allow clear vision after the cataract removal.
The AcrySof™ IQ Vivity™ Extended Vision IOL provides clear distance vision (e.g., for watching children playing in the backyard). In addition, the AcrySof™ IQ Vivity™ Extended Vision IOL allows for better intermediate (working on a computer, applying makeup or shaving) and some near (reading, knitting) vision compared to what a monofocal IOL would provide. The AcrySof IQ Vivity IOL is not a multifocal IOL, as it uses new X-WAVE™ technology to provide a broader range of vision.
In addition to the potential benefits of the AcrySof™ IQ Vivity™ Extended Vision IOLs, the AcrySof IQ Vivity Toric IOLs provide corneal astigmatism correction, which may provide clearer vision if you have corneal astigmatism. The AcrySof™ IQ Vivity™ Toric Extended Vision IOL is offered in several models for varying levels of corneal astigmatism. The most appropriate model will be chosen by your surgeon based on the amount of your corneal astigmatism if any. There is a chance you may still need glasses for distance, intermediate, and/or near vision.
You will get the full benefit of the AcrySof™ IQ Vivity™ Extended Vision IOL when it is implanted in both eyes. Please discuss with your eye doctor whether this is the right IOL for you.
There are some side effects that can be associated with the design of IOLs that provide a broader range of vision, which may be worse with a monofocal IOL. These side effects include visual disturbances such as glare, rings around lights, starbursts, and a decrease in the ability to distinguish objects from their background, especially in dim lighting. These side effects may make it more difficult to see in some situations.
Intraocular lenses are used during cataract surgery to replace the damaged lens of the eye with an implant that clears up and corrects vision, oftentimes leaving patients with little to no dependence on glasses. Up until now, patients with astigmatism did not have the same opportunities that other cataract patients have had in correcting their condition with the types of IOL lenses that were available. Typically, the astigmatic patient would need an additional surgical procedure, such as refractive surgery or LASIK, to correct their vision after the procedure. If the patient did not want to undergo another surgical procedure, the only option for correction would be the use of either contact lenses or glasses to address their astigmatism. Toric IOLs are able to accommodate for the condition of astigmatism. Toric IOLs are specially designed to correct astigmatism along with overall vision during cataract surgery, offering complete vision correction.
A monofocal toric IOL is designed to provide clear distance vision and correct corneal astigmatism. There are different models of monofocal toric IOLs for varying levels of corneal astigmatism. With a monofocal toric IOL, you will be able to see objects far away more clearly than with a monofocal IOL, but there is still a chance that you may need glasses for distance vision. Also, you will most likely still need glasses for near distance activities such as reading, writing, sewing as well as intermediate distance activities such as viewing a cell phone, applying makeup or shaving, or working on a computer.
In addition to the potential benefits of Multifocal IOLs, the Multifocal Toric IOLs provide corneal astigmatism correction, which may provide clearer vision if you have corneal astigmatism. There is a chance you may still need glasses for distance, intermediate, and/or near vision.
