There are many types of IOLs on the market now and new ones are still under development, including lenses to correct for astigmatism, block UV light, and a range of other specific characteristics. Very few insurance carriers cover specialty lenses. Each of these lenses require specific training and certification for implantation.
A monofocal IOL is the traditional IOL approved by the FDA in 1981. It is a single focus lens that generally provides good distance vision, requiring the recipient to wear glasses or bifocals to have good near and intermediate vision. When cataracts are present in both eyes, patients may elect to have both eyes implanted with IOL’s that correct for distance. This provides good distance vision, but patients will require reading glasses for up close functions. Patients may elect to have one eye implanted with a near lens and the other with a far lens, a technique called Monovision, which many contact lens wearers are already familiar with. Dr. Iskander uses the most advanced monofocal intraocular lenses available, the wavefront optimized lenses, whenever possible. These intraocular lenses have the best potential for visual quality and for better night vision.
Presbyopia Correcting Lenses
These are newer IOLs that allow for greater range of vision and decreased dependency on glasses or contacts. The best part of these presbyopia correcting lenses is that they correct for presbyopia, which is the stiffening of the eye’s lens and superciliary ligaments that occurs for everyone as they age. These lenses work in different ways. Depending on your visual needs and characteristics, Dr. Iskander will make sure you understand the options and help you make the most informed decision possible. It is important to understand that although these lenses give more ranges of vision, the visual outcome cannot be compared to the natural lens of a perfectly seeing eye at a young age where the eye has perfect ranges of vision. Patients may be spectacle free for most of the time, however, they may still need glasses for some difficult visual tasks like night driving or reading, especially in dim illumination or reading very fine print. Here is a very general overview of some of the lenses Dr. Iskander prefers.
Tecnis Multifocal Lens
The Tecnis® multifocal lens is designed to help correct astigmatism and/or presbyopia during cataract surgery. Like other IOLs, this lens makes the recipient more independent by reducing or eliminating his or her dependence on spectacles. Patients who spend a lot of time indoors will find that they can see better in dim light, and those who spend more time outdoors will find that their visual acuity is improved. Tecnis® Multifocal provides good vision in low light environments, a greater range of good vision (near, far, etc.), and has a very high rate of patient satisfaction. About nine out of ten Tecnis® patients report never needing to wear glasses for any activities.
Tecnis Symfony IOL
The Tecnis Symfony® Lens is designed to reduce or eliminate the need for reading glasses or bifocals after undergoing cataract surgery. The Tecnis Symfony® lens is comprised of a multifocal lens design, which has multiple power rings that help patients see at various distances. The Symfony IOL also is designed to reduce glare and halos, especially while driving at night. The Tecnis Symfony® design allows for an extended range of vision, providing a new option for patients that may result in better vision across a broader range of distances. This new lens significantly reduces any glare and halo effect, producing approximately the same amount of night vision issues as monofocal lenses, which is close to zero.
Alcon PanOptix Trifocal IOL
Abbott Pharmaceuticals has recently developed the PanOptix® Trifocal intraocular lens, which can help patients with astigmatism reduce or eliminate their need for reading glasses or bifocals after cataract surgery. This innovative new lens is helping cataract patients see better than they have in years. In a recent study, 99% of PanOptix lens recipients stated that they would choose the same implantable lens again, and 98% said that they would recommend it to a friend or family member. This multifocal IOL is designed to give you excellent vision over a range of distances. With the PanOptix IOL, most patients will have good vision near, far, and intermediate. Patients who choose this lens may eliminate or significantly reduce their dependence on reading glasses or bifocals.
“I was scared to have cataract surgery after I was diagnosed by my optometrist. After going to several ophthalmologist in town, I decided to go with Dr. Iskander of San Antonio Eye Specialists because I felt most comfortable with him. He took the time to explain the difference between modern cataract removal and old fashion cataract surgery like my mother had. After undergoing laser-assisted cataract removal, I can see clearly again! I also chose a premium lens implant which has freed my from reading glasses and bifocals for nearly all activities! Thanks again Dr. Iskander!”

"I was very pleased with my experience with Dr. Nader G. Iskander.It was good to be treated with professionalism and care. When I say the doctor and all the other employees of the Doctors Care made me feel that I was in safe hands and even made me smile when I left, then you can believe they are the best. I am truly grateful and highly recommended San Antonio Eye Specialists."

“I highly recommend Dr. Nader Iskander and his staff for anyone who is in need of professional vision care servicies. Dr. Iskander performed successful Cataract surgery on me for both of my eyes during 2013 when I was 64 years old. My vision improved immediately to 20/20. There was no pain or side effects. I go back once a year for an annual eye exam with Dr. Iskander. I am happy to say that I have had no problems with my vision since my Cataract surgery. I just had my annual eye exam with Dr. Iskander at SA Eye Specialists and I am glad to say my vision is still 20/20 at 70 years old.”
