Abstract Details

Purpose:

To compare intermediate and near optical and predicted visual performance provided by the different technologies designed to extend depth of focus.

Setting:

Implant R&D, Johnson and Johnson Surgical Vision, Netherlands

Methods:

Four IOL technologies were included in the comparison: TECNIS monofocal ZCB00, the next generation monofocal, TECNIS Eyhance ICB00, and two other diffractive models that extend depth of focus and correct chromatic aberration. Model ICB00 consists of a continuous higher order aspheric surface that results in a continuous power change from the center to the periphery. This refractive profile was designed to improve intermediate performance as compared to an aspheric monofocal IOL. Measurements were performed in white light. Binocular visual acuity was simulated using the area under the MTF (MTFa) from 1 to 50 cycles/mm.

Results:

Simulated visual acuity predicted an improvement in intermediate vision of approximately one line for model ICB00 as compared to model ZCB00. Simulated intermediate vision was comparable for the two achromatic diffractive extended depth of focus designs and superior than that of the two monofocal IOL designs (ZCB00 and ICB00). Finally, simulated near vision was better for the achromatic diffractive extended depth of focus technologies.

Conclusions:

The optical quality and simulated visual performance provided by the next generation monofocal, TECNIS Eyhance IOL (model ICB00), were compared to that of TECNIS 1-piece monofocal (model ZCB00), and that of two diffractive achromat designs, such as Tecnis Symfony. Preclinical data showed that while intermediate vision is better for the next generation monofocal lens (as compared to its predecessor), both intermediate and near vision are superior for the achromat diffractive extended depth of focus technologies.
