Abstract Details

Purpose:

To compare toric and monofocal intraocular lens (IOL) implantation in patients with cataract and corneal astigmatism.

Setting:

University Eye Clinic Maastricht, the Netherlands.

Methods:

Eighty-six patients with bilateral cataract and at least 1.25 D of corneal astigmatism were randomized for either bilateral toric or bilateral monofocal IOL implantation. Six months postoperatively the uncorrected and best-corrected distance visual acuity (UDVA and BDVA), refraction, misalignment, spectacle use for distance vision and complications were evaluated.

Results:

Postoperatively, the UDVA in the toric and monofocal group was 0.06 ± 0.14 and 0.21 ± 0.16 LogMAR, respectively (P<0.001). The BDVA was comparable in both groups: 0.00 ± 0.11 LogMAR in the toric group and -0.01 ± 0.09 LogMAR in the monofocal group(P>0.05). Seventy percent of patients with toric IOLs achieved a Snellen UDVA of at least 20/25, compared to 30% of patients with monofocal IOLs (P< 0.001). A refractive cylinder of 1.0 D or less was achieved in 74% of patients in the toric group and 30% of patients in the monofocal group (P<0.001). Seventy-eight percent of patients with toric IOLs reported being spectacle independent for distance vision, compared to 22% of patients with monofocal IOLs (P<0.001). Mean misalignment of toric IOLs was 3.6 ± 3.2 degrees and IOL repositioning was required in 1 patient.

Conclusions:

Toric IOLs result in a better UDVA, a lower refractive astigmatism and a higher spectacle independence for distance vision compared to monofocal IOLs.
