Distance-dominant diffractive multifocal IOL provides good visual acuity at far, intermediate distances

Issue: January 10, 2016

Good uncorrected and corrected visual acuities at far and intermediate distances were obtained with a distance-dominant diffractive multifocal IOL, according to a study.

The prospective study included 64 eyes of 32 patients who received a ReSTOR SN6AD2 diffractive multifocal IOL with a +2.5 D near addition (Alcon). A control group of 64 eyes of 32 patients received an SN60WF monofocal IOL (Alcon).

At 3 months after surgery, mean uncorrected and distance-corrected near visual acuities, measured at at 0.3 m, and intermediate visual acuity, measured at at 0.5 m, were better in eyes that received a multifocal IOL vs. a monofocal IOL (P = .0412).

The groups had similar visual acuities at other distances.

Mean manifest spherical equivalent refraction was –0.18 D in both groups.

Mean corneal astigmatism was 0.49 D in the multifocal IOL group and 0.55 D in the monofocal IOL group. The difference was not statistically significant.

Both groups had similar photopic and mesopic contrast visual acuity, glare visual acuity, glare disability and glare symptoms.

Significantly more patients in the multifocal IOL group reported halo symptoms than in the monofocal IOL group (P = .0009). – by Matt Hasson
