If your doctor has told you that you are in the early stages of developing cataracts or has suggested that refractive lens exchange would be a good vision correction option, you might want to research the new emerging lens implant technology in the field of ophthalmology. If you are nearing the age for cataract surgery and want a reliable vision correction solution premium lens implants might be a good fit for you. Premium lens implants have been helping patients do the activities they might not have been able to do because of their vision. Imagine golfing, driving, or reading the newspaper with less dependence on glasses.
Traditional Lens Implants
Prior to the advent of Premium IOLs, cataract surgery was only available with a monofocal lens. This meant that the lens implant was only capable of focusing at one range of vision, usually at a distance. For years patients would have monofocal lens implants that would help them see better far away, but they would require eyeglasses after cataract surgery to help them see anything close up. Patients who had an astigmatism would often need to wear glasses at a distance as well.
Understanding what lens is right for you!
Only you and your surgeon can decide what lens is best for you. When deciding, it is best to keep in mind the type of activities you do on a daily basis, and to choose the lens that will fit your lifestyle the best.
Correcting Distance Vision with a Monofocal IOL
A monofocal IOL is designed to provide clear distance vision. This means you will be able to see objects far away. However, you will need glasses for reading and any type of close detailed work. Monofocal IOLs have been the standard implant used for decades to help patients after a cataract is removed. Millions of monofocal IOLs have been successfully implanted providing cataract patients with clear distance vision.
Correcting Distance Vision and Astigmatism
Today’s cataract patient demands excellent vision after surgery, and wants their astigmatism and refractive error corrected at the same time. There are two ways we correct pre-existing astigmatism during cataract surgery. The most advanced method uses a new type of lens implant, called a Toric lens, which incorporates unique optics to compensate for specific deficiencies in your vision.
Toric lenses greatly reduce the likelihood of needing a second procedure after cataract surgery to correct residual astigmatism. For those patients who suffer from astigmatism so pronounced that they are outside the power range of the Toric lens, we recommend a combination treatment of lens replacement and relaxing incisions that delivers both improved vision and astigmatism correction. Once we fully understand your level of astigmatism, and desire for improved distance vision and/or near vision, we will recommend the appropriate lens implant option for you.
Correcting Distance and Near Vision with Multifocal or Accommodating IOLs
Previous lens replacement technologies provided only one focal point – distance – leaving people dependent upon reading glasses or bifocals after cataract surgery. Recent advances in accommodative and multifocal technology now make it possible for you to read the words on prescription bottles, magazines, newspapers and computer screens, without magnifying glasses or bifocals, while still clearly seeing objects at a distance. These lenses have the ability to consistently offer improved vision at all ranges – near through distance. With the recent introduction of three new lenses – ReSTOR 3.0, Crystalens HD and Tecnis Multifocal – the vision we can help you maintain as you age is better than ever before in the history of ophthalmology.
The AcrySof ReSTOR multifocal lens provides the greatest degree of independence from glasses of all the lenses we implant. Because of its patented apodized diffractive technology, the ReSTOR lens allows for powerful near vision while providing excellent night vision for the majority of our patients.
The TECNIS mulitfocal lens can improve functional vision so you can see well, even in low-light situations like driving at night, or reading a menu in a dimly-lit restaurant. The TECNIS implant was designed with an aspheric shape to correct for certain, more complex vision errors, known as higher-order aberrations, which helps improve ability to see contrasting objects, particularly at night.
The Bausch & Lomb Crystalens is an accommodating lens that can help treat both your cataract and presbyopia (difficulty focusing up close because of the natural aging process). Crystalens uses the eye’s natural muscles to flex, allowing the eye to focus at various distances.
The Bausch & Lomb Trulign™ accommodating lens was designed with astigmatism-correcting properties engineered into the lens optics. Trulign makes it possible to correct presbyopia and astigmatism in a single procedure
