Abstract Details


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.


Optimax and Ultralase Eye Clinics


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.


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.


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.
