Welcome to Panoptix trifocal lens the latest strategy to reverse presbyopia.
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.
Construction of Panoptix trifocal lens
This is a single piece biconvex lens with a central optic made of a high refractive index hydrophobic acrylic material capable of being folded without damage prior to insertion through a smaller wound. The central 6.0 mm optic has two haptics on either end giving an overall lens diameter of 13 mm. In the central 4.5 mm of the optic there is a diffractive portion which divides the light to create +2.17D Intermediate (+1.65D at cornea) and +3.25 D Near (+2.35D at Cornea) add power. Front surface of the lens has negative spherical aberrations to counteract the positive ones generated from the cornea.
Panoptix Toric trifocal lens to correct astigmatism and presbyopia
Panoptix toric has a posterior toric surface marked by 3 dots on each side of the flat axis. If it rotates from intended axis it loses effect. If rotation is more than 30 degrees, it may make astigmatism worse.
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 time tested platform produces glistening’s. These glistening’s can affect vision in some patients.
We will be soon be comparing advantages and disadvantages of panoptix with restor, tecnis multifocal, symfony toric and crystalens.
