Advanced IOL Implants


As we reach our 40s, our eyesight becomes a bit blurry, and it becomes harder to focus on up-close objects.

  • This is known as presbyopia, and it's the result of the natural lens in each eye becoming less flexible so that it doesn't change shape as it should to properly focus on objects up-close.
  • This changing of shape is called accommodation.

So to see clearly at short distances, we resort to reading glasses.

You've heard about LASIK, but LASIK won't get rid of those reading glasses permanently. Now there's another option, Crystalens®.

Dallas Crystalens® - Vision Without Compromise

Accommodative Intraocular Lens (IOL) implantation is a surgical procedure to correct presbyopia. It differs from other refractive surgical procedures like LASIK because it involves replacing the natural lens of the eye, rather than reshaping the cornea. The Crystalens® intraocular lens implant is creating amazing vision all over North Texas. This revolutionary procedure is generally for adults over the age of 40 who desire high-quality vision without the assistance of bifocals or trifocals; the vision results are stunning. The recently FDA approved HD model includes improvements to the prior Crystalens accommodating interocular lens. It provides a better vision than the prior models. Crystalens HD produces an overall clearer vision through better contrast sensitivity and depth of focus.

Since Crystalens® received FDA approval in November of 2003, Dr. Carter has been the world leader in the number of implants performed!

Crystalens Fort WorthAs the first U.S. surgeon to perform Crystalens® after FDA approval, Dr. Carter has performed more Crystalens® procedures than any other eye surgeon in the world. Dr. Carter offers Dallas residents peace of mind: "Because Crystalens® works with the natural focusing ability of your eye, our patients can see both distances, intermediate and near without glasses. Many of our patients are stunned to find out that their personal best vision is even better than they had hoped for." Consider Crystalens® to restore the quality eyesight you had when you were younger, as well as your quality of life.

Vision the way you want it. Seamless. Effortless. Natural.

Restor The ReSTOR® intraocular lens is an (IOL) multifocal lens implant used to replace the eye's natural lens for clearer vision.

You can choose the ReSTOR® lens to correct presbyopia or cataracts so that your eyes can focus easily at both close and far distances. To focus back and forth in that way, the natural lens must change its shape slightly and this is referred to as accommodation. However, after the age of 40, the natural lens becomes less flexible making it difficult for the eye to focus up-close. Unlike the Crystalens®, the ReSTOR® lens is not dependant on the movement of the lens to yield clear vision.

How the ReSTOR® lens works

The ReSTOR® lens uses a method of spreading light, called apodized diffractive technology, as well as refractive technology. Similar technology has been used for many years in telescopes and microscopes to improve image quality. Now it's available for patients of Carter Eye Center who want to see both near and far without glasses. The optical surface has concentric rings of different focus or power. Clearer distance vision is enabled by the rings nearer the lens' edge (like the upper part of bifocal glasses). Clearer near vision is provided by the inner rings (like the reading part of bifocal glasses).

Advantages of the ReSTOR® lens


  • They're flexible, so Dr. Carter can fold them up and insert them through tiny incisions.
  • Since the incisions are so tiny, you enjoy rapid healing and minimal discomfort
  • The exact engineering and construction of the ReSTOR® lens have dramatically reduced many of the traditional problems of multifocal lenses.
  • The "near" portion of the lens causing blurriness when you're looking at distant objects and the "far" portion of the lens doing the same when you're looking at close objects.

Dr. Carter has been implanting ReSTOR® lenses to help Dallas residents fight cataract and presbyopia. Call now to find out how this advanced technology may be able to make your life much easier.

TECNIS™ Multifocal


TECNIS™ Multifocal intraocular lens is a presbyopia-correcting lens implant which works to improve the patient’s full range of vision following cataract surgery. The Tecnis™ multifocal lens is designed to provide multiple focal points simultaneously for far, intermediate and distance vision. The goal of the Tecnis™ IOL is to achieve less dependence on glasses or contact lenses. If you believe you or a loved one may have a cataract, consult Carter Eye Center for a full eye examination.

During the surgical procedure, the lens is inserted through a tiny incision in the eye. This surgery follows the same cataract surgery process used with other lens implants known as phacoemulsification. During this procedure, the natural crystalline lens is broken up using ultrasonic waves. The crystalline lens is the part of the eye behind the cornea that can thicken over time and become cloudy, forming cataracts that obstruct vision. During the procedure, the unhealthy crystalline lens is broken up into minute fragments and the tiny pieces are then vacuumed away. The next process involves the insertion of the TECNIS™ multifocal IOL. The lens is inserted through a small incision in the eye and unfolds into the appropriate position. This new lens will ultimately correct both nearsightedness and farsightedness.

Common Questions about the Tecnis™ IOL

Will I be completely free from glasses?
Although this lens implant has very good results at our practice, the results will vary depending on your vision and specific lifestyle. Some patients will require the use of reading glasses to read fine print or newspapers. Many people do not require glasses at all after the implantation of this lens.

How is the Tecnis™ Multifocal lens different from traditional intraocular lenses?
The Tecnis™ IOL is a multifocal intraocular lens. Unlike traditional monofocal (single vision) lens implants, the Tecnis Multifocal lens provides quality vision at all distances-near(reading), intermediate(computer use or cooking), and far(driving).
