The TECNIS Eyhance monofocal intraocular lens provides a continuous change in power from its outer area to its center. This creates a unique surface that improves intermediate distance vision extends the depth of focus while maintaining distance image quality. Tests have also shown that the Eyhance lens has superior nighttime contrast. With these improvements over traditional monofocal IOLs, the Eyhance IOL completely redefines the concept of what a monofocal lens is and can be.
