What are Intraocular Lenses? (IOL)

Home | Cataracts | What are Intraocular Lenses? (IOL)

A cataract causes the eye’s natural lens to become clouded. In order to restore clear vision, an ophthalmologist must replace the eye’s natural lens with an artificial substitute, the IOL or intraocular lens. The intraocular lens is a very common surgical procedure with an estimated one million implanted in the United States each year.

The advanced technology IOLs are an important part of the Aloha Laser Vision cataract surgery services in Honolulu. You can find out which is most appropriate for your unique vision needs when you contact Aloha Laser Vision in Honolulu, Hawaii.

AcrySof® IQ PanOptix® Trifocal Lens

The PanOptix® Trifocal IOL is a next-generation multifocal lens that can provide clear vision at a range of distances—near, intermediate, and far—and various lighting conditions. For patients who have an active lifestyle, desire high-quality vision, and want to eliminate their need for glasses following cataract surgery, the PanOptix Trifocal lens may be the best option for meeting their expectations. The PanOptix Trifocal lens also offers the benefit of correcting for presbyopia and astigmatism if needed.

Alcon’s proprietary ENLIGHTEN™ optical technology enables the PanOptix Trifocal lens to deliver optimized vision at all distances. Traditionally, multifocal lens makers have grappled with trying to improve intermediate distance without compromising the quality of near and distance vision. The PanOptix Trifocal lens has been designed with ENLIGHTEN™ optical technology, which allows for clear, uncompromised vision at any distance and has led to outstanding rates of patient satisfaction. In Alcon’s research, 99% of PanOptix Trifocal lens recipients would choose to have the same lens placed again.

Our medical director, Dr. Alan Faulkner, is once again the first eye surgeon in Hawaii to debut the latest optical technology—he was the first ophthalmologist in Hawaii to implant PanOptix Trifocal lenses in early September, 2019. He has been very impressed by the results his patients have achieved with PanOptix Trifocal lenses post-operatively. For patients who are good candidates, he recommends this state-of-the-art lens as a worthwhile investment in one’s vision.

AcrySof® ReSTOR® Lens

restorThe ReSTOR® lens provides significantly better vision at all distances by distributing the light coming into the eye as a response to how small or wide the pupil of the eye is at that moment. The ReSTOR® lens doesn’t work with the muscles in the eye (as do some other IOLs), so it doesn’t depend on the movement of the lens to give clear vision. Part of the ReSTOR® lens provides good near vision by using a set of graduated rings in the center of the lens. The other part of the lens provides the good distance vision.

In clinical studies, 80 percent of patients who received the AcrySof® ReSTOR® lens reported never wearing glasses for any activities. In fact, nearly 94 percent said they would have the AcrySof® ReSTOR® lens implanted again if they needed it. With the ReSTOR® IOL, you too can drive, work on a computer, or read a book with little or no need for glasses.

After receiving a ReSTOR® lens, your distance vision will most likely be very good within a day or two after surgery, and your near vision will improve within another few days or a week. Because the AcrySof® ReSTOR is a multifocal lens, you may see halos or glare, but this phenomenon is rare and usually fades with time. In addition, your intermediate vision may not be as clear as your near and distance vision.

Tecnis® MF

technis-IOLThe TECNIS® Multifocal intraocular lens (IOL), developed by Abbott, was created to restore range of vision for cataract patients with or without presbyopia. Presbyopia is a common vision disorder typically associated with aging that makes reading and focusing on objects up close very difficult. Conventional monofocal IOLs were designed to focus primarily at a far distance and do not correct presbyopia, while multifocal IOLs provide focus at near, intermediate, and far distances.

TECNIS® Multifocal lenses correct presbyopia and give patients the ability to focus at a full range of distances under any lighting condition. In a recent study, 9 out of 10 patients with TECNIS® Multifocal lenses reported that they never wear glasses following surgery.


The TECNIS® Symfony IOL is the newest FDA-approved intraocular lens from Abbott Medical Optics Inc. This state-of-the-art IOL provides patients with an extended range of high-quality vision. Compared to other multifocal IOLs, TECNIS® Symfony significantly reduces glare and halos and provides smooth transition between focal points at various distances. The majority of patients who have the TECNIS® Symfony placed during cataract surgery are impressed with the clarity and fluidity of their vision, and many report complete independence from their glasses. Clinical studies have shown an overwhelming 97% patient satisfaction rate with the TECNIS® Symfony. Symfony is available in non-toric and toric versions to correct for astigmatism.

If you are interested in finding out if the TECNIS® Symfony IOL is right for you, we encourage you to schedule a consultation with our experienced Dr. Alan Faulkner.

Which Advanced Technology IOL Is Right For Me?

Much depends on you – your eyes, your needs, your work, your hobbies – in short, your particular circumstances. The ReSTOR® and Tecnis® advanced technology lens implants are available to cataract patients at Aloha Laser Vision in Hawaii because of the quality of vision they each provide. Dr. Faulkner will recommend the IOL that best fits your needs, following your comprehensive examination. It’s also important for you to know that an IOL can’t correct pre-existing vision problems such as a visual field that is already lost, floaters, or flashers. It is also important to note that although almost everyone experiences improved vision after cataract treatment, the post-surgery uncorrected vision of some patients will be better than that of others.

Dr. Alan Faulkner is committed to providing their patients with the highest quality vision treatments and procedures that serve to improve and optimize vision. To schedule a consultation, examination, or to find out more about intraocular lenses, please contact Aloha Laser Vision of Honolulu, Hawaii today.
