Rotational stability, centration, and patient satisfaction with a trifocal toric intraocular lens

Abstract

Purpose:

To evaluate the rotational stability, decentration, visual outcomes, and patient satisfaction after bilateral implantation of a trifocal toric intraocular lens (IOL), Clareon PanOptix Toric. Setting:

San Carlos Hospital, Madrid, Spain. Design:

Prospective, single-center, observational, noncomparative. Methods:

Patients aged 50 years or older suitable for cataract surgery without comorbidities and with regular corneal astigmatism >1.50 diopters (D) were bilaterally implanted with the Clareon PanOptix Toric IOL and followed up for 3 months. Outcomes measured included IOL displacement and rotation, quantified by the PIOLET software. In addition, refraction and uncorrected visual acuity at far (4 m) were measured, along with corrected visual acuities, monocular and binocular, at far (corrected visual acuity [CDVA]), intermediate (DCIVA), and near (DCNVA) distances. Results:

A total of 80 eyes from 40 patients were included in this study. At 3 months, the mean rotation was 1.04 ± 0.97 degrees, and the mean displacement was 0.19 ± 0.36 mm along the x axis and 0.19 ± 0.25 mm along the y axis. The postoperative spherical equivalent was −0.09 ± 0.35 D. Binocularly, the mean visual acuities were CDVA, −0.03 ± 0.05 logMAR; DCIVA, 0.07 ± 0.08 logMAR; and DCNVA, 0.09 ± 0.07 logMAR. Regarding satisfaction, 97% of patients indicated they were either very satisfied or fairly satisfied. Conclusions:

The bilateral implantation of the Clareon PanOptix Toric IOL demonstrated excellent rotational stability, minimal decentration, and effective astigmatism correction. It provided strong visual acuity outcomes and high patient satisfaction, making it a viable option for patients seeking spectacle independence.
