Purpose: To compare visual performance of a zero-aberration (SoftecHD) aspheric intraocular lens (IOL) with the spherical equivalent (Softec1).

Methods: Residual refraction, best-corrected distance and near visual acuity, reading speed, contrast sensitivity and aberrometry were recorded 1 month post-operatively in 37 patients with the SoftecHD in one eye and the Softec1 in the other.

Results: Range of focus was significantly better in the SoftecHD IOL eye than the Softec1 IOL eye and the print size at which optimum reading speed could be achieved was significantly smaller.

Conclusions: Depth of field was significantly improved with the aspheric IOL compared with the spherical IOL, without any compromise in distance visual performance.
