The Tecnis Eyhance Enhanced Monofocal Lens

How it differs from a standard monofocal

A standard monofocal has a single spherical or aspheric power. Eyhance modifies the central optic with a continuous change in power from the center outward, which extends the depth of focus modestly into the intermediate range without splitting light. The result is a lens that behaves like a monofocal in every way patients notice at night, while giving usable vision at arm's length that a standard monofocal does not.

What patients experience

Sharp distance vision with full contrast. Comfortable vision for a computer screen, a dashboard or a phone held at a normal distance. Readers for print. No halos or glare beyond what a monofocal produces. Because there is no diffractive optic, Eyhance generally tolerates residual prescription, mild macular change and previous refractive surgery well.

Who suits Eyhance

• Patients who want monofocal clarity and do not mind readers, but who would like better screen and intermediate vision
• Patients for whom a multifocal or EDOF is not advised because of macular disease or an irregular cornea
• Patients choosing a monofocal under insurance who want a modest upgrade
• Blended vision candidates, where an enhanced monofocal set slightly nearer in one eye gives useful near vision

A toric Eyhance corrects astigmatism at the same time.
