Objective And Subjective Outcomes With A Novel Full Range Of Vision Iol With Spiral Optic Design

In this study, the refractive accuracy, visual acuity and patient-reported outcomes (PROMs) of a novel non-diffractive, full-range of vision intraocular lens (IOL) were evaluated in patients undergoing cataract surgery. The aim was to assess visual function and overall patient satisfaction, particularly when considering the short daylight hours of Northern Finland during winter.

A retrospective analysis was conducted on 52 eyes of 26 patients implanted with the RayOne Galaxy (RAO605G) or Galaxy Toric (RAO615X) IOL. Preoperative assessments included a slit lamp examination, keratometry, biometry and subjective refraction. At the one-month follow-up, subjective refraction and monocular and binocular, uncorrected and corrected visual acuity were measured at distance (4m), intermediate (60cm), and near (40cm). Patient-reported outcomes were collected using RayPRO, a digital system designed to track PROMs following cataract surgery, including patient satisfaction and the evaluation of the occurrence of halos and glare. A total of 100 eyes (50 patients) are expected to be included by the time of the presentation.

At the one month post-op, 81% of eyes were within ±0.25D of target, 90% within ±0.50D and 100% within ±1.00D. Monocular UDVA was 0.02 ± 0.11 LogMAR and CDVA -0.05 ± 0.09 LogMAR. Binocular UDVA achieved -0.06 ± 0.08 LogMAR, with CDVA at -0.10 ± 0.06 LogMAR. For intermediate vision, monocular UIVA measured 0.08 ± 0.09 LogMAR, and DCIVA was 0.09 ± 0.09 LogMAR. Binocular UIVA and DCIVA both achieved 0.02 ± 0.07 LogMAR. Near vision results demonstrated monocular UNVA at 0.13 ± 0.08 LogMAR and DCNVA at 0.13 ± 0.10 LogMAR. Binocular UNVA was 0.08 ± 0.08 LogMAR, while DCNVA achieving 0.09 ± 0.09 LogMAR. PROMS showed that among the 26 patients, one reported nighttime halos or glare, with none of the patients reported daytime dysphotopsia.

The RayOne Galaxy, spiral IOL, demonstrated excellent refractive predictability and provided a full range of functional vision at distance, intermediate, and near. Spectacle independence was achieved with minimal reported halos or glare. These findings suggest that this non-diffractive IOL effectively restores visual function while maintaining a low incidence of dysphotopsia, a crucial factor in environments with limited natural light.
