True. Because this lens works just like the lens of a camera, a clouded lens will keep light and images from reaching the retina, which sends images to your brain. This is the reason that a cataract causes sharp images to become blurry, bright colors to become dull, and seeing at night more difficult. Once your natural lens becomes clouded, the only treatment available to improve your sight is to remove the natural lens and replace it with an artificial lens.

True. However, cataracts may also form as a result of eye trauma or a chronic medical condition (e.g., diabetes).

False. Although many eye conditions can be improved upon, or their progression slowed, by a person's diet, there are no medications or diets that will reduce the effects of a cataract.

False. It is time to have cataract surgery when your normal lifestyle - reading the morning paper, completing work tasks, driving to the grocery store or seeing the expression on the face of a loved one is jeopardized by impaired vision. The right time is different for each patient. If your normal lifestyle is not substantially impaired, resist any pressure to schedule cataract surgery. Remember that is in a surgical procedure that should be elected only when you believe that your quality of life is substantially compromised.

True. Depending on your unique vision needs and conditions, pain relief can be achieved through the application of topical eye drops without the need for more intensive anesthesia. By using a topical anesthetic, the risks of cataract surgery are considerably reduced. Topical anesthesia eliminates potential complications such as perforation of the eye, hemorrhage, or damage to the optic nerve associated with using a needle. In addition, it eliminates the surgical risks common to the administration of anesthesia.

True. Intraocular lenses were first introduced in 1949 and are available today in all kinds of shapes, sizes and lens materials. In the 1990s, foldable lenses were introduced, quickly becoming the most popular lens implants in the world because of their ability to provide excellent visual results.

False. Lens implants come in different materials and in different "powers" and sizes. In order to receive the full benefits of cataract surgery, your surgeon must calculate the correct lens to use for your unique eye conditions. This requires extensive pre-operative measurements performed by a variety of state-of-the-art diagnostic instruments. Cataract surgery must be customized to each patient - it is not a "one size fits all" procedure.

False. Advances in "phacoemulsification" technologies permit your surgeon to extract the natural lens in small pieces, thereby avoiding the need for a large incision for extraction. In addition, the newest foldable artificial lens implants require a small incision for implantation. The result is that only a very small incision is required for cataract surgery, as long as your surgeon is trained in the latest cataract surgery technologies.

True and False! The most common type of lens implant is called a "monofocal" lens implant. This lens will provide you with clear, crisp vision at one point of distance. At other points of vision - particularly at near vision - the lens will not function as perfectly, thereby requiring most cataract patients to wear reading glasses for close-up vision.

The FDA has recently approved the first major innovation in implantable lenses in the past decade - the "multifocal" lens. These lenses provide good "walk around" vision, reducing the need for glasses for close-up tasks. Pepose Vision Institute is a leader, not only in St. Louis but also in the nation, in the use of multifocal lenses. It is the only St. Louis provider to offer all three of the lenses that have been FDA-approved - because each lens has a slightly different advantage in terms of vision zone. Choosing the correct multifocal lens - to deliver the very best vision outcome possible - requires substantial pre-operative testing and post-operative follow-up.

True. LASIK patients require special attention when it comes to calculating the optimal power of the lens that is implanted. A surgeon who does not take into account the effects of LASIK or other vision correction surgeries will not select a lens implant that maximizes the vision improvement resulting from cataract surgery

True. Most health insurers consider cataract surgery "functional" surgery. Therefore, it is covered in the same way as other surgeries, and is subject to the same deductibles and co-payments. However, the use of deluxe multifocal lenses is considered an "upgrade" and is often excluded from insurance coverage. In such instances, the insurer will cover the cost of "standard" monofocal cataract surgery, and permit the patient to pay the additional charges associated with the deluxe multifocal lens implant. These charges include the higher cost of the lens and the more extensive pre- and post-operative services provided by your surgeon.

False. The ideal surgeon is one who is extremely experienced in cataract surgery, is up-to-date on the latest surgical innovations, and is equally experienced in vision correction (for those who have had previous vision correction surgery) and the diagnosis and treatment of other eye conditions such as glaucoma. In this way, your eye surgeon can treat any confounding eye conditions that could compromise the benefits you will enjoy from cataract surgery. Moreover, because the cornea is a critical factor in calculating the optimal intraocular lens for each patient, a cornea-trained surgeon is better equipped to achieve the best vision outcome possible. The surgeons at Pepose Vision Institute understand that the goal is to preserve and, where possible, restore your eyesight, regardless of cause of vision loss.
