Abstract Details


To evaluate the rotational stability and visual outcomes of a single-piece hydrophilic acrylic toric IOL over a 1.5-year follow-up period.


Konventhospital der Barmherzigen Brüder, Linz, Austria


Forty eyes of 26 cataract patients (mean age: 72.8 ± 7.9 years) with pre-existing corneal astigmatism of 1.0 to 2.6 D were enrolled in the study. Mean axial length was 23.17 ± 0.88 mm. The rotational stability of the Torica-aA IOL (HumanOptics) was evaluated using retroillumination photographs taken within 24 h after surgery and 1 week, 6 months and 1.5 years postoperatively. Other main study outcomes were assessed 6 months and 1.5 years postoperatively and included subjective refraction, keratometry, uncorrected and corrected distance visual acuity (UDVA, CDVA). The efficacy of the astigmatism correction was evaluated by vector analysis.


There was no significant change in the parameters evaluated between the 6 months and 1.5 years follow-ups. At last visit, mean absolute IOL misalignment was 2.03 ± 2.15° (range 0.00 to 7.50°). Mean residual refractive cylinder was -0.60 ± 0.41 D. There was a significant reduction in the magnitude of the J0 vector postoperatively (p<0.0001) with a mean absolute change of 0.76 ± 0.40 D. The mean J45 vector was close to zero preoperatively and postoperatively. Mean monocular UDVA and CDVA was 0.09 ± 0.12 logMAR and -0.01 ± 0.12 logMAR, respectively. No treatment with Nd:YAG laser was required.


Implantation of the Torica-aA IOL was safe and effective in reducing low to moderate pre-existing corneal astigmatism and provided good rotational stability and visual outcomes over a 1.5 years follow-up period.
