Advanced Implantable Lenses
Restoring Vision After Cataract Removal
Leading the way in vision correction, Dr. Zieker incorporates Laser-Assisted Cataract Surgery and Advanced Lifestyle Lenses to provide improved vision beyond simply removing cataracts. The lenses you choose may be the lenses you look through for the rest of your life. Be sure to understand the options available so that you have the best chance to attain the vision you want.
Once your cataracts have been removed, Dr. Zieker will replace the lens of the eye to restore vision. There are several different implantable intraocular lens (IOL) types:
Monofocal or Single-Focus Lens- Offers a single focal point, usually set for distance. Most insurance plans cover this implant. Reading glasses will still be needed by most patients, and distance glasses may still be needed depending on the degree of astigmatism (curvature of the cornea) and other anatomic variables. Most patients will feel comfortable driving and watching television without glasses.
Multifocal Lens- Offers multiple focal points, such as near, intermediate and distance, thereby improving the range of vision. The primary goal is reduced dependence on glasses for near and distance sight. These patients can typically read without glasses. Most patients are also comfortable driving and watching television without glasses. The intermediate vision range, (arm’s length), is considered functional for most people. For example, the car dashboard is typically clear, whereas computer fonts at arm’s length may not be (many patients simply move their computer screen closer). Multifocal lenses are best for people who seek decreased dependence on glasses.
Laser-Assisted Cataract Surgery- The Catalys Precision Laser System uses laser technology that can perform several surgical steps previously done by hand. This offers greater accuracy and precision than can be achieved manually. The laser can also treat mild amounts of astigmatism. This is the best way to have cataract surgery for those who are candidates.
Astigmatism Correction- The limbal relaxing incision (LRI) is an advanced technique only used by some cataract surgeons. Dr. Zieker uses this technique in order to surgically correct astigmatism at the time of cataract surgery. For many, this increases overall visual outcomes, and increases opportunity for independence from eyeglasses.
ORA- Optiwave Refractive Analysis that provides real-time, during surgery measurements to help achieve optimal lens implant power.
Toric Lens- Toric lens implants are designed to correct astigmatism from inside the eye. The goal is better quality of vision and possible independence from distance glasses.
Accommodating Lens- These lenses mimic the natural ability to move within the eye to provide a greater range of vision, and may reduce the likelihood of needing reading or intermediate glasses. The current strength of this technology is intermediate range, or arm’s-length.
Although cataract surgery is typically covered by insurance, most of the advanced technologies and techniques are not covered. They are considered elective by most insurance companies.
Which lens is right for you?
There is no single option that is best for all patients. You must consider your hobbies, activities, lifestyle, work-related tasks, etc. to decide which lens is best for you. Cost and convenience also weigh into the decision, especially determining how important it is to you to attempt reducing dependence on glasses.
Dr. Zieker can help you choose which options are in your best interests to pursue. Financing plans for the premium lenses are available.
People with astigmatism may be candidates for refractive cataract surgery and have both conditions corrected with one procedure, reducing the overall recovery time and optimizing visual outcomes.
