A new class of implants called the Tecnis Symfony implants create an extended depth of focus lens. Its the first lens to employ an enhanced range of vision while correcting for chromatic aberration( color distortion). This lens elongates the range of vision allowing for great distance vision and good near. The focal point is elongated providing for a continuous range of vision. A great strength of this lens is that it can also correct for astigmatism with the topic lens option, if a significant amount is present. This lens option may not provide the same strength of near vision as the tecnis multifocal but the extended range of focusing helps reduce glass need for distance and near.
