Refractive Outcomes And Dysphotopsia Following Implantation Of A Novel Spiral Full Range Of Vision Iol: A Multicenter Real-World Comparison

This analysis aims to present early real-world visual outcomes and dysphotopsia following cataract surgery with implantation of the RayOne Galaxy (Rayner, UK), a novel spiral full range of vision intraocular lens (IOL) and to contextualize these outcomes relative to a hydrophobic trifocal intraocular lens used in routine clinical practice.

Multicenter real-world study conducted at Hospital Alemán and Good Vision, Buenos Aires, Argentina, in patients undergoing cataract surgery with implantation of presbyopia-correcting intraocular lenses.

This observational multicenter case series includes data of patients undergoing cataract surgery with implantation of either a RayOne Galaxy, or a hydrophobic trifocal intraocular lens. The RayOne Galaxy cohort comprised 33 patients (66 eyes), including 29 bilateral and 4 unilateral implantations. The trifocal cohort included 34 patients (65 eyes), with 32 bilateral and 2 unilateral implantations. Follow-up ranged from 3 to 12 months. Postoperative assessment included uncorrected distance and near visual acuity and patient-reported dysphotopsia, specifically the presence of halos. 

In the RayOne Galaxy cohort, uncorrected distance visual acuity of 20/20 was achieved in 67.2% of eyes, with additional eyes achieving 20/25 or better. Near uncorrected visual acuity of 0.5 was achieved in 54.6% of eyes. No patients implanted with the spiral optic IOL reported halos (0%).
In the hydrophobic trifocal cohort, uncorrected distance visual acuity of 20/20 was achieved in 46.2% of eyes, and near uncorrected visual acuity of 0.5 was achieved in 74.2% of eyes. Patient-reported halos were reported in 9.2% of cases.

In this early multi-center experience, implantation of the RayOne Galaxy, a novel spiral full range of vision IOL lens, provided favorable uncorrected distance and functional near vision with no reported dysphotopsia. When compared with outcomes observed in a hydrophobic trifocal IOL cohort treated in the same clinical setting, the RayOne Galaxy demonstrated comparable visual performance with a lower incidence of halos. These findings suggest that the RayOne Galaxy may represent a suitable presbyopia-correcting option for patients seeking a broad range of vision with reduced photic phenomena.
