Clearview 3 Lens | Real-World Experience after Cataract Surgery | Refractive Lens Exchange

The Clearview 3 is a segmented bifocal lens implant with a transition zone, designed to give good far, intermediate, and near vision without glasses. The lens is implanted at the time of Cataract Surgery or Refractive Lens Exchange (RLE).

How does it work?
When light rays or light "energy" enters our eyes, that light energy needs to be focused on our retina in order to see clearly. The Clearview 3 has a far segment dedicated to focusing light energy from far way, another segment that focuses light rays from near, and a transition zone that focuses light rays from intermediate distance. You don’t need to look in a certain direction to bring those light rays into focus. For example, you don't need to look towards the near segment to read up close. No matter the direction you look, then lens implant is focusing light energy from all these distances simultaneously. As long as light energy is entering your pupil, and the lens is centered properly, objects that are far away or near to you will be brought into focus. Now, the pupil size regulates the total energy entering the eye. So in theory, if the pupil is too small, there is less total light energy available and therefore one may expect some decreased performance in low light settings. Also, if the lens is not properly centered, the near vision can be better than the far, or the far vision can be better than the near. The segments are sharing light energy. Since there are no rings on this lens implant, it seems to cause much less of a halo effect than with diffractive multifocal lenses with rings, such as the panoptix, synergy, symfony, or odyssey. The Clearview however, does not correct astigmatism like most diffractive multifocal lenses on the market today. No lens is perfect, but this lens is certainly worth considering for patients who desire freedom from glasses, with an average or larger pupil size, and who don’t have too much astigmatism.
