A diffractive multifocal toric IOL restored near, intermediate and distance visual acuity and offered spectacle independence in patients with corneal astigmatism, according to a post-marketing study.

The multicenter study included 284 eyes of 142 patients who underwent microincision cataract surgery and implantation of the At Lisa toric 909M toric IOL (Carl Zeiss Meditec).

At 6 months, 165 of 185 eyes (89.2%) were within ±1 D of emmetropia.

Mean refractive cylinder decreased from –2.39 D to –0.49 D.

At 1 month postoperatively, uncorrected distance visual acuity was 0.1 logMAR or better in 100 of 208 eyes (48%) and 0.3 or better in 177 of 208 eyes (85%). This was stable at 6 months. Also at 1 month, monocular corrected distance visual acuity was 0.1 or better in 187 of 225 eyes (83%) and 0.3 or better in 225 of 225 eyes (100%). This was stable after 1 month, as was binocular corrected distance visual acuity.

Distance corrected near visual acuity was 0.3 or better in 79 of 87 eyes (91%) from 1 month to 6 months; binocular distance corrected near visual acuity equaled monocular corrected near visual acuity.

Intermediate visual acuity exceeded 0.22 at each follow-up visit.

IOL rotation was 5° or less in 95.8% of IOLs at 3 months and 6 months.
