For many cataract patients, the standard IOL implant provides satisfactory vision. With standard IOLs, patients who do not have astigmatism generally achieve good distance vision without the need for glasses, though they are likely to be dependent on reading glasses for close-up vision. However, patients with significant astigmatism, or whose lifestyles make reading glasses inconvenient, often opt for an upgraded lens implant. Hoopes Vision’s cataract specialists are experts in the use of two types of premium lens: toric IOLs and multifocal IOLs.
The first toric IOL received FDA approval in 1998. Before the advent of toric IOLs, cataract patients with significant astigmatism almost always needed glasses – usually bifocal – in order to have good vision after surgery. Toric IOLs are used to correct astigmatism; in patients with moderate to severe astigmatism, they can help greatly to reduce or eliminate dependence on eyeglasses or contacts postoperatively. A toric IOL, like a toric eyeglass or contact lens, has additional refractive power located along one axis.
Toric IOLs require extra care on the part of the surgeon, since the IOL must be placed so that the axis of additional power lines up exactly with the location of the astigmatism in the patient’s eye. The cataract specialists at Hoopes Vision are trained and highly experienced in the use of toric lens implants such as the Tecnis® Toric, and have at their disposal the most advanced diagnostic and surgical equipment.
Intraocular lens implants, or IOLs, replace the eye’s natural crystalline lens after cataract surgery or clear lens exchange. Traditionally, the surgeon would select IOLs for each patient based on what would help the patient achieve the best possible distance vision, and the patient would be told to expect to need reading glasses for close work after surgery.
Beginning in the 1990s, however, a new type of lens implant was developed: the multifocal IOL, which featured zones of added refractive power in the lens itself. These new IOLs promised improved vision at all distances, and have been subject to constant refinement and improvement in the years since their introduction. Today newer, high-tech multifocal IOLs such as the Tecnis® MF can reduce, or in many cases completely eliminate, the need for reading glasses after surgery. Multifocal IOLs have the advantage of outstanding post-operative vision at a wide variety of distances, but they do represent an additional cost over the conventional procedure. Also, not all patients are good candidates for multifocals; only an experienced surgeon can determine whether they would be of benefit. At your initial cataract examination at Hoopes Vision, the surgeon will discuss with you whether the Tecnis MF is a good option for your unique eyes and visual needs.
During cataract surgery the cloudy, natural lens of the eye is removed, and an artificial lens, called an intraocular lens, or IOL, is inserted into the eye. The IOL most commonly used in cataract surgery is a monofocal lens, which only allows the person to see at a distance, with closer objects being out of focus. In contrast, the TECNIS® Symfony lens was specifically developed to provide a full range of continuous high-quality vision following cataract surgery and is the first implant that can treat reading vision and astigmatism simultaneously.
In clinical studies the Symfony lens:
• Provided seamless day-to-night vision. Most patients could see objects sharply and clearly at near, intermediate, and far away distances, and points in between.
• Provided high-quality vision. Some IOLs may leave patients with an inability to focus clearly due to competing wavelengths of light passing through the lens at different angles (known as chromatic aberration), or with vision that is not completely focused because of the shape of the lens (known as spherical aberration). The Symfony lens has been engineered to correct these issues.
This new IOL option is for patients who want excellent postoperative vision at all distances while minimizing dependence on glasses. Symfony has been offered in Europe since 2014, where it has produced outstanding results for tens of thousands of patients. Symfony received final FDA approval this summer, and is now available to patients in the United States. Hoopes Vision is excited about this latest advancement in intraocular lens technology.
A multifocal lens implant focuses light from distance and near simultaneously. This feature addresses both distant and near vision and makes the recipient less dependent on glasses or contact lenses.
No. The natural lens of a young person changes shape to produce a change in focus. As a person ages, the natural lens becomes more rigid and functions more like a monofocal lens. Lens implants do not change shape. A multifocal lens compensates for the eye s inability to change shape by allowing the eye to see at distance and near simultaneously through the same optic.
The primary alternative to multifocal lens implantation is monofocal lens implantation. If you request a monofocal lens, you will have to decide whether you want distance vision lens implants in both eyes or whether you want a distance vision implant in one eye and a near vision implant in the other eye.
No. The decision needs to be made prior to cataract surgery.
No. It is recommended for most patients, but not for patients who have problems with their retina (e.g. significant macular degeneration, epiretinal membrane macular pucker , macular holes, significant diabetic retinopathy, history of severe retinal detachment, retinal dystrophies or degenerations, retinal vascular occlusions), advanced glaucoma affecting central vision, irregular corneal astigmatism, corneal scarring, keratoconus, corneal dystrophies or optic neuropathy.
