Abstract

Background: To assess the visual quality and the tolerance to low refractive errors of two trifocal intraocular lenses (IOL) with different amounts of spherical aberration (SA).

Methods: The study included patients having bilateral implantation of the AcrySof® IQ PanOptixTM (aberration-correcting) or the RayOneTM (aberration-free) Trifocal IOL. Three months after the surgery patients underwent: monocular/binocular and uncorrected/corrected distance visual acuity (VA) and binocular defocus curves. Binocular contrast sensitivity (CSF) and subjective halo perception were assessed with the best distance correction (CDVA), with a positive defocus of + 0.50D and with a negative defocus of -0.50D. Patient's satisfaction was evaluated with the Catquest9-SF questionnaire.

Results: This study included 54 eyes (28 with PanOptix and 26 with RayOne) of 27 patients. Both groups achieved corrected/uncorrected and monocular/binocular distance VA values better than 0.0 logMAR (1.0 decimal) with no statistically significant differences between them (p > 0.05 for all cases). Defocus curves showed a VA of 0.1 logMAR or better between -2.5 and + 1.0D with no differences between groups (p > 0.05 at all distances). Overall CSF values remained stable under the induced residual refractions for both groups. The halo effect remained stable for the PanOptix group but increased with myopization in the RayOne group (p = 0.02). The questionnaire showed high rates of patient's satisfaction with no differences between groups.

Conclusion: Both lenses showed overall good visual outcomes and offered high rates of patient's satisfaction. Moreover, in normal patients with trifocal IOLs, the combination of residual refractive errors and certain amounts of SA may increase some visual disturbances.
