The basic lens provided by Medicare insurance has brought a brighter and clear world, yet only for one focal point Most of these patients will require glasses to receive a full range of vision after standard cataract surgery.
In 2005, Medicare made it possible for patients to pay out-of-pocket for refractive lens implants. Our center has been placing an assortment of advanced lifestyle lenses since that time.
Dr. Bruce Ballon describes the lens choices that are currently available at The Harman Eye Clinic. The Tecnis Multifocal family of intraocular lenses are excellent for correction of patients with cataract and the desire to be less dependent on glasses for reading. The first lens to be approved is the +4.0 [ZMBOO] or as I like to call it, the “Papa Bear“. It has the strongest reading add power, with a focus point of 33 cm (13 inches) and we have implanted it at The Harman Eye Clinic since it was first released. It gives the patient excellent distance and reading vision, and with “cheaters” for computer, excellent intermediate. The lens works best for patients with healthy eyes (for example, no macular degeneration ). Unlike the ReSTOR lens from Alcon Labs, the reading vision with the Papa Bear (and Mama and Baby Bear for that matter) is much better than the ReSTOR lens in dim light, however the reading focus point with the Papa Bear for taller patients just seemed too darned close!

In response to this observation, AMO released two lower add lenses, that I like to call the “Mama Bear” and “Baby Bear“! I guess I remember that when Goldilocks sat on the baby bear’s chair it broke, so the Mama Bear seemed to be the happy medium. Nevertheless, I still like to tell patients that there is “nothing as good as original equipment from the manufacturer as a teenager!” when it comes to replacing our own crystalline lenses. So even though I think the Mama Bear lens seems “just right!” for many patients, it isn’t perfect. The Mama Bear lens +3.25 [ZLB00] is a slam dunk in my opinion with 96% of patients who are spectacle independent, and less than 5% with significant halos at 1 year, and less than 2% with significant glare. The reading focus point is 42cm (about 16 inches). Some patient still require computer glasses. The Baby Bear lens +2.75 [ZKB00] is designed for people with goals for less spectacle dependence for distance and intermediate vision, such as golf, shopping and reading price tags, computer. 98% of patients were spectacle independent for distance and intermediate targets. At The Harman Eye Clinic we use the ORA-VerifEye technology to measure the power of the eye during surgery to improve refractive outcomes. Instead of about 75% of patients with a precise refractive target (within 0.5 diopters), almost 90% are right where we want them to be. This technology helps all patients, whether it is post-LASIK, or asthmatism correcting lens implant patients, bifocal implant patients or patients who simply don’t want to wear glasses for driving and don’t mind wearing them for reading.
