Comparison of clinical performance and subjective outcomes between two diffractive trifocal intraocular lenses (IOLs) and one monofocal IOL in bilateral cataract surgery

Background: To compare clinical outcomes and subjective experience after bilateral implantation of two diffractive trifocal and one monofocal intraocular lenses (IOLs). Methods: Fourty-eight patients received bilateral implantation of the RayOne Trifocal IOL (Rayner), the AcrySof IQ PanOptix IOL (Alcon), or the AcrySof IQ SN60WF IOL (Alcon). At 1-month, 3-month, and 12-month follow-up visits, the tested outcomes were monocular and binocular uncorrected and corrected distance, intermediate at 70 cm, and near at 30 cm visual acuities, subjective refractive outcomes, defocus curves, contrast sensitivity and ocular aberrometry. Subjective patient satisfaction in terms of visual disturbance and spectacle independence was also evaluated. Results: Each group comprised 32 eyes (16 patients). Refractive outcomes of RayOne and PanOptix IOLs were comparable. Both trifocal IOLs demonstrated superior visual acuity to the AcrySof monofocal IOL at near and intermediate ranges and along the defocus curves at all points other than at 0.0 D. The patient satisfaction results were comparable between the RayOne and PanOptix trifocal IOL groups. Conclusions: Both trifocals performed similarly providing good visual outcomes at all distances, demonstrating superior visual acuity compared to the monofocal IOL. Patients implanted with these trifocal IOLs reported similar levels of quality of vision and satisfaction. The RayOne trifocal and PanOptix IOLs are a valuable alternative for patients wishing to seek spectacle independence and low visual disturbances when undergoing cataract surgery.
