Abstract Details

Purpose:

To evaluate functional vision outcomes with binocular implantation of a new non-diffractive extended vision intraocular lens (Alcon DFT015).

Setting:

Multicenter, multicountry clinical trial sponsored by Alcon

Methods:

This study bilaterally implanted 154 and 119 subjects with DFT015 and SN60WF (monofocal control), respectively at 19 sites in Canada, UK, Spain and Australia. At 6 months post-op, binocular uncorrected distance (UDVA, 4m), intermediate (UIVA, 66cm), and near visual acuity (UNVA, 40cm) and defocus curve were recorded along with subjective assessment of spectacle use and visual disturbances (QoV, McAlinden). Reading speed at 66cm was measured using MNREAD.

Results:

DFT015 provided 20/20 binocular UDVA, > half a logMAR line improvement in UIVA, and > 1 line improvement in UNVA. Statistically significantly more subjects implanted with DFT015 compared with SN60WF never needed spectacles overall and for intermediate tasks; and 83% with DFT015 never or only sometimes needed spectacles for near tasks. DFT015 implanted subjects achieved fluent intermediate reading speeds (80 words/minute or better) at every font size tested down to 1M. In the DFT015 group, 73% or more subjects were not at all bothered by starbursts, halos, and glare compared to 58% or more with SN60WF.

Conclusions:

Compared with an aspheric monofocal, this non-diffractive extended vision IOL improves near and intermediate vision without affecting distance vision; and reduces need for spectacles while maintaining a monofocal-like visual disturbance profile.
