Purpose
To assess the rotational stability, centration and visual outcomes in patients undergoing cataract surgery who were bilaterally implanted with a toric trifocal intraocular lens.
Setting
Hospital Clínico San Carlos. Universidad Complutense. Ophthalmology Department. Madrid. Spain
Methods
The study includes 44 patients with symmetric bilateral intraocular lens implantation. The lens under evaluation was a hydrophobic toric trifocal intraocular lens (Clareon PanOptix Toric, Alcon). The lens' rotational stability and centration have been measured by means of the PIOLET software, which relies on recording and image processing techniques to determine lens rotation and centration based on slit-lamp images. Visual outcomes measured, all evaluated 1 and 3 months postoperatively, included monocular and binocular uncorrected distance (UDVA), corrected distance (CDVA), distance-corrected intermediate (DCIVA), and near (DCNVA) visual under photopic conditions.
Results
Interim results at one month postoperatively showed a mean monocular UDVA, CDVA, DCIVA (60cm), and DCNVA (40 cm) under photopic conditions of 0.10 ± 0.03, 0.04 ± 0.04, 0.2 ± 0.07, and 0.2 ± 0.07 logMAR. Binocular CDVA, DCIVA and DCNVA were 0.01 ± 0.05, 0.18 ± 0.06, 0.17 ± 0.05 logMAR. At the 24 h post-surgery evaluation, the mean rotation was 1.60 ± 2.80 degrees. The displacement was 0.006 ± 0.02 mm along the X axis and 0.02 ± 0.17 mm along the Y axis. The rotational stability was evaluated one month after surgery compared to 1 day follow-up. The mean rotation was 1.00 ± 2.30 degrees. The displacement was 0.005 ± 0.007 mm along the X axis and 0.005 ± 0.006 mm along the Y axis.
Conclusions
The hydrophobic trifocal toric intraocular lens under study has shown an excellent rotational and centration stability and visual outcomes for all distances evaluated.
