What Is The Difference Between A Standard Intraocular Lens Implant (IOL) And A High Tech IOL?
It used to be over the past six decades that the only choice for a cataract surgery implant was the standard ‘monofocal’ IOLs. They still offer good functional ‘distance’ vision, but reading glasses are almost always needed for near vision.
If you want to be less dependent on eyeglasses or contact lenses, or if you have astigmatism, then the FDA approved High Tech Lens Implants (IOLs) are a better choice. Because of the advanced technology utilized in these High Tech IOLs, your vision may be better than it would be if the standard IOL was used.
Why is it important to decide which IOL you want before your cataract surgery?
Once you have cataract surgery, you cannot change your mind to upgrade to a High Tech IOL. That is why it is so important to really think about this decision ahead of time. At The Eye Associates, we strive to answer all your questions and help you through this decision process. We understand that your lifetime of good vision depends on it.
Categories of High Tech IOLs
High tech IOLs come in several categories: multifocal, multifocal toric, accommodating, and accommodating toric.
Multifocal IOLs, such as the AcrySof IQ ReSTOR® Multifocal, the TECNIS® Multifocal, and the TECNIS Symfony, work somewhat like a progressive or bifocal eyeglass lens by offering you an expanded range of vision, distance and near.
Accommodating IOLs, such as the Crystalens and the Trulign Toric, have a design that allows the lens to flex slightly when your eye’s natural focusing muscles move, thereby mimicking your own eye’s natural ability to see at multiple distances, much like before you became presbyopic and needed reading glasses. The Trulign Toric is an accommodating toric IOL that corrects astigmatism as well as offering a full range of vision – distance to near.
Multifocal Toric IOLs, like the TECNIS Symfony Toric IOL and the AcrySof IQ ReSTOR Toric also corrects astigmatism and offers a full range of vision.
“Monofocal” Toric IOLs, like the AcrySof IQ Toric and Tecnis Toric, correct astigmatism, giving good distance vision but you will still require reading glasses.
The good news is that there are many choices, and together you and your surgeon will be able to decide which option is best for you.
