Advanced Medical Optics' Tecnis(R) IOL Designated as a New Technology Intraocular Lens
About Functional Vision
Youthful functional vision is the ability of the young crystalline lens tocompensate for the spherical aberration of the cornea, providing qualityvision. With age, the crystalline lens loses the ability to compensate forthe cornea, resulting in increased spherical aberration and reduced functionalvision.
Patients with reduced functional vision face many challenges that severelyaffect their quality of life such as walking or climbing stairs in low-lightor unfamiliar settings, reading or doing work at close range, or driving atdusk, at night or in the fog.
The unique technology of the Tecnis(R) lens shows decreased sphericalaberration and improved night driving simulator performance (in a clinicalstudy, patients viewing a rural road through a Tecnis(R) lens identified apedestrian sooner than through a traditional spherical lens). These findingssuggest there is likely to be a meaningful safety benefit to elderly driverswith Tecnis(R) lenses, and to the drivers and pedestrians with whom they sharethe road. The results of the performance/ functional tests demonstrate thatthe Tecnis(R) lens improves functional vision, which in turn may improvepatient safety for other life situations under low visibility conditions.
An analysis by the Potomac Institute for Policy Studies states thatimproved driving performance from reduced spherical aberration with theTecnis(R) lens could translate into annual preventable costs of automobileaccidents ranging from
Dr. R. Bruce Wallace , III, Clinical Professor of Ophthalmology at LSUMedical School stated, "We have had a number of our Tecnis(R) patients commenton their enhanced vision at night and in other low light conditions, adding amargin of safety to their activities, especially for driving."
