Purpose
This study evaluates the clinical outcomes of a rotationally symmetric, fully refractive, multifocal (toric) intraocular lens (IOL) following cataract surgery, with an additional focus on the impact of corneal aberrations on visual performance.
Setting
A prospective, monocentric study conducted at the Department of Ophthalmology, University of Rostock, Germany.
Methods
In this study, 50 eyes from 25 patients (mean age: 69.0 ± 5.4 years, mean axial length: 23.78 ± 0.96 mm, mean corneal astigmatism: 1.06 ± 0.45 D) were included. All eyes had cataracts but no other pathology. Surgery was performed with a PRECIZON Presbyopic NVA (toric) IOL under local anesthesia. Postoperative examinations were performed after 1 day, 1 week, and 3 months to assess (un)corrected visual acuity (near, intermediate, and distance), refractive astigmatism, IOL rotation, and defocus curve (subjective and objective, including ray-tracing, iTrace). The influence of preoperative corneal aberrations, such as spherical aberration and coma, was examined using iTrace and Pentacam to determine predictors for patient selection.
Results
Three months after surgery, uncorrected distance visual acuity significantly improved from 0.64 ± 0.34 logMAR to 0.04 ± 0.09 logMAR (p < 0.001). Uncorrected near visual acuity reached 0.26 ± 0.17 logMAR postoperatively. Mean refractive astigmatism was reduced to -0.32 ± 0.38 D, demonstrating effective correction of preoperative astigmatism. Patients did not spontaneously report significant visual disturbances such as glare or halos. However, when specifically asked, 3 out of 25 patients described mild visual phenomena, none of which were considered bothersome. The data analysis is currently ongoing, and results will be presented.
Conclusions
The PRECIZON Presbyopic NVA IOL by Ophtec appears to be a promising option for achieving a spectacle independence after cataract surgery, with minimal visual disturbances. Additionally, understanding preoperative aberrations may refine patient selection, enhancing satisfaction and optimizing visual outcomes
