Abstract Details

Purpose:

To evaluate the efficacy and rotational stability of the Zeiss AT Lisa toric intraocular lens (IOL) in correcting preoperative astigmatism in cataract and refractive lens exchange patients.

Setting:

Optimax and Ultralase Eye Clinics

Methods:

This prospective observational study included 34 eyes from 20 consecutive patients who underwent implantation of an AT Lisa Trifocal toric IOL with micro-coaxial cataract surgery between January 2014 and September 2014. Outcomes of visual acuity, refractive and keratometric astigmatism, and IOL rotation after 1 day, 1 month, 3 months, follow-up were evaluated.

Results:

At final follow-up, 95% of eyes showed an uncorrected visual acuity of 20/25 or better. The postoperative keratometric value was not different from the preoperative value; mean refractive astigmatism was reduced to -0.28±0.38 diopter (D) from -2.50 ±0.48 D. The mean rotation of the toric IOL was 2.45±3.39 degrees at final follow-up. All eyes exhibited rotation of less than 10 degrees.

Conclusions:

Early postoperative follow-up showed that implantation of the Zeiss Trifocal toric IOL is an effective, safe, and predictable method for managing corneal astigmatism in cataract and refractive lens exchange patients.
