Lens implants have been used in nearly all cataract operations performed in this country since 1982. This wonderful invention allows patients to see after cataract surgery without thick glasses or contact lenses that were necessary in the past. These lens implants are called Implant Lens or IOL.
Today lens implant technology allows for more choices in vision correction benefits and outcome after cataract surgery.
The most recent developments in lens technology involve what is called Wavefront design. Essentially a computer model of the human eye is used to increase our understanding of how we focus light rays for clearest vision. These studies have shown that a simple spherical lens intraocular implant can leave a patient with less than perfect vision. Wavefront design implants are aspheric, meaning the curvature of the lens surface changes depending on how far you are from the center of the intraocular lens. This more sophisticated shape improves the sharpness of a cataract patient's vision after surgery. At EyeHealth Northwest we only use the best intraocular lenses available. Using technology such as Wavefront design ensures that our patients obtain the best possible visual result from cataract surgery. A Wavefront lens is an excellent option for those who don't mind wearing glasses after their surgery and want to improve the quality of their vision.
For cataract patients with astigmatism, successful cataract surgery is only half the battle for regaining quality vision. EyeHealth Northwest offers the Toric lens implant, a design proven to correct both your cataracts and astigmatism simultaneously. Implanted in the eye to restore distance vision after cataract surgery, the Toric lens has a unique patented design that provides both spherical and astigmatic correction.
How Astigmatism affects your vision:
Corrects your distance, intermediate and near vision. Reducing your dependence on glasses for your activities after surgery.
A multifocal lens implant provides excellent vision after cataract surgery at a variety of distances. For the vast majority of patients, having a multifocal lens implant means that you will be able to see at distance and up close without being dependent on glasses. Patients choosing to have a multifocal lens implant will likely find that they can drive, watch television, read or do crafts without the need for glasses.
As with any surgical procedure there are associated risks and benefits. While there may be a decrease in the need for glasses some patients may notice rings around lights at night. These side effects may make it more difficult to drive at night or perform tasks in low light conditions. While virtually everyone experiences an improvement in vision after cataract surgery, some people will have better uncorrected vision than others. Therefore, it is important to discuss the potential risks and benefits with your doctor.
The accommodating is flexible and able to change focus in response to effort by our focusing muscles in our eyes just as the natural lens does for people under the age of forty. The Crystalens has the great advantage of allowing virtually all patients to see at both distance and intermediate distance without using glasses. It is particularly good for driving, computers, cell phones, and newspaper sized print.
The current Crystalens is limited in one aspect: not all patients are able to use their eye muscles effectively enough to give good reading vision all the time, especially for fine print. In the future we will see numerous other accommodating lenses that attempt to better simulate the natural human lens in all cases. Researchers hope to someday create lenses that will actually perform better than the natural lens, and be fully adjustable throughout our lives as we age. It is likely that in the not too distant future we may be replacing the natural human lens in patients of all ages, not just older patients, as a method of improving the vision of young and old alike.
Good candidates for the Mulitfocal or Accommodating lens should have realistic goals for their vision and receive a complete evaluation by an Ophthalmologist who specializes in deluxe lens implantation. EyeHealth Northwest has surgeons with vast experience in the implantation of these types of state of the art lenses. Our surgery centers have access to all FDA approved lenses. EyeHealth Northwest is the largest provider of deluxe lens implants in the Portland Metro area.
