Purpose : The objective of this study was to evaluate the outcome of Acrysof Toric intraocular lenses (IOLs) implantation in cataract surgery for the correction of regular corneal astigmatism.

Methods : Twenty eyes of 16 patients with cataract and regular corneal astigmatism of 1.00-4.00 diopter (D) underwent surgery. Depending on the amount of corneal astigmatism, an Acrysof Toric IOL of type SN60T3, SN60T4, SN60T5, SN60T6, SN60T7, SN60T8 or SN60T9 was implanted. Studied parameters before and after surgery included uncorrected visual acuity (UCVA), best corrected visual acuity (BCVA), residual refractive astigmatism, change in corneal astigmatism, IOL rotation, and spectacle independence for distance vision.

Results : At six months after surgery, all eyes (100%) had a UCVA of 20/32 or better and 80% had a UCVA of 20/25 or better. Spectacle independence for distance vision was 85% in the studied eyes. The change in corneal astigmatism ranged between 0.25 and 0.5 D in all eyes. The residual astigmatism was 0.75 D or less in 100% of the cases and 0.0 to 0.5 D in 90% of the eyes. IOL rotation was zero degrees in 65% of the eyes, 4° or less in 90% of the eyes, and 5° or more in 10% of the eyes by six months after surgery.

Conclusion : Using Acrysof Toric IOLs (SN60T3 to SN60T9) during cataract surgery for patients who have regular corneal astigmatism of 1.0 to 4.0 D is an effective, predictable, and rather stable option for correcting astigmatism.
