LENS IMPLANTS TAMPA
Before coming in for an appointment with us, many of our patients feel overwhelmed and confused by the many choices available for cataract surgery. However, there are really only a few decisions you have to make, and Dr. Updegraff will be happy to guide you through them to determine the best lens implant option for you.
STANDARD LENS IMPLANTS
All of us know family members or friends who no longer need glasses after having cataract surgery. However, it’s important to understand that this isn’t always the case. Why?
Although all eye care professionals strive to give you 20/20 vision with a standard lens implant, the truth is that they aren’t quite as accurate as glasses, contacts, or LASIK.
When we fit you with glasses, contacts, or LASIK, we put lenses in front of your eyes. You choose the lenses you like, and then we copy those lenses with nearly 100% accuracy.
Standard lens implants are a little more complex, because we don’t ask for you feedback. Instead, we use sophisticated units to measure your eye’s length and the curvature in front of it; these values are then placed in a formula that tells Dr. Updegraff what power lens will most likely give you 20/20 distance vision.
The accuracy of modern standard lens implants is approximately 80%. And in general, because of this you don’t have an absolute choice or guarantee of distance vision.
So, to determine whether you should choose standard lens implants or high-tech lens implants, answer this question: Do you mind having to wear glasses (for distance and near vision) after having cataract surgery?
If the answer is no, then your choice is simple: have a standard lens implant and cataract surgery.
Standard lens implants is the most economical choice if you don’t mind wearing glasses, and even so, it typically provides an excellent quality of vision. In addition, some patients with standard lens implants are fortunate, and the surgery eliminates their need for glasses.
However, if the answer is yes, your goal is to become as independent from glasses as possible, you should have high-tech lens implants.
HIGH-TECH LENS IMPLANTS
There are two primary ways that high-tech lens implant surgery is different from standard lens implant cataract surgery: the high-tech lenses themselves and bioptics, which is the utilization of secondary procedures such as LASIK.
High-tech lens implants are designed to help you see distance, intermediate, and possibly near. There are three general types of high-tech intraocular lens implants (IOLs) that can help reduce or eliminate your dependence on glasses, and each has its strengths and tradeoffs. Dr. Updegraff will discuss them with you thoroughly to help guide you in determining which has the most likelihood of achieving your goals.
The accommodating IOL works by flexing with the contracture of the ciliary muscle inside the eye. It provides the patient with intermediate vision, used for working on the computer or seeing the dashboard while driving, as well as distance vision.
About 50% of patients are able to “squeeze,” or move, the lens enough to get out of their reading glasses, too. If you have previously worn monovision glasses, we can also improve near vision with accommodating IOLs by setting one eye slightly near.
Although getting out of reading glasses cannot be guaranteed with this technology, the aspheric style of this lens typically results in excellent night/low light vision and a crisp image through the lens implant.
Dr. Updegraff was the first surgeon in the state of Florida to implant the Crystalens, one of the first accommodating IOLs available in the U.S.
Unlike the accommodating IOL, which flexes inside the eye, the multifocal IOL works by focusing light from distance, intermediate, and near. It is currently the only technology that can remove one’s dependence on reading glasses, and because it’s an optical principle, every patient experiences similar near results.
Multifocal IOLs have a long history, and Dr. Updegraff has implanted every style dating back to the first generation Array™ in the mid-1990s. The problem with the early multifocal lenses was the poor night vision that resulted from light glinting off the rings of the lens in low light. Since that time, however, many lens manufacturers have made multiple revisions of this technology to improve quality of vision and diminish night vision disturbances.
Dr. Updegraff utilizes the most improved multifocal IOL technology to provide the best results available.
Another approach for patients with high degrees of astigmatism is the Toric IOL. The Toric IOL is a high-technology lens that is similar in shape to a toric contact lens, which is used to correct the “toric” shape of a cornea.
Astigmatism, which causes blurred vision, is a refractive error that occurs when the cornea is shaped like a football rather than like a basketball. As a result, light entering the eye focuses on two points in the retina instead of one. The toric IOL is specifically designed to reduce or eliminate astigmatism while also improving distance vision. After it is implanted inside the eye, it compensates for the cornea’s distortion and focuses light clearly in the retina.
Just like a standard lens implant, high tech IOLs have an 80% accuracy rate. If it’s necessary to fine-tune your vision after your high-tech lens implant surgery, Dr. Updegraff will utilize bioptics – secondary procedures such as LASIK that help you possibly achieve 20/20 distance vision. Because of this, it’s extremely important to determine whether or not you are a candidate for these secondary procedures prior to choosing high-tech lens implants.
