Panoptix trifocal lens
FDA gave approval in the last week of August 2019 to Alcon’s Panoptix trifocal technology. We are excited to welcome another option to the family of PIE (presbyopia Implant in eye). We will explore the nuances of this lens, the lens material, the unique optical design and finally patient satisfaction in clinical and international trials.
Multifocal lenses are defined as having more than one focus. They can have two in the traditional multifocal like tecnis and restor. Trifocals have three foci. Finally quadrifocal have four foci. Panoptix is actually a quadrifocal lens which has been modified to behave like a trifocal to improve distance vision.
If you are interested in physics and optics you can read on otherwise skip this paragraph. In a trifocal there are three points of foci. The distance is set at infinity. The intermediate add should be twice the focal length of the near. If near is at 40 cm than intermediate focus will be at 80 cm. In a quadrifocal we have distance still set up at infinity. The second add is at 1.5 times the near add and the third add is at 3 times the near. So if 1st add is 40 cm 2nd will be 60 and third at 120 cm.
In Panoptix a special enlighten proprietary technology shifts this extended intermediary focus towards infinity or distance. This improves the distance vision.
ENLIGHTEN ™ Optical Technology
Panoptix lens is built on the acrysof platform of Alcon. More than a million acrysof lens have been implanted. This timetested platform produces glistening’s. These glistening’s can affect vision in some patients.
