Purpose

The purpose of this prospective analysis is to evaluate the impact of pupil size and spherical aberration on the clinical outcomes of patients implanted with a new full range of focus IOL with a novel spiral optic.

 

Setting

Ooginstituut Aalst. Brusselsesteenweg 88, 9300 Aalst, Belgium.

Methods

A retrospective study was carried out to assess the visual outcomes of 59 consecutive eyes of 31 patients implanted with either RayOne Galaxy (RAO605G) or RayOne Galaxy Toric (RAO615X) IOL. Measured parameters at one month and three months post-op included: manifest refraction (MRSE), monocular corrected and uncorrected distance visual acuity (CDVA, UDVA) , intermediate visual acuity (DCIVA, UIVA), and near visual acuity (DCNVA, UNVA), monocular defocus from +1.0D to -4.0D. Additional measures at three months include binocular defocus from +1.0D to -4.0D. Subjective symptoms of halo/glare were also recorded.

Results

At the one month post-op, 58% of eyes were within +/-0.25D of refractive target, 94% within +/-0.50D. Monocular UDVA achieved 0.03 ± 0.07 LogMAR, with CDVA achieving -0.02 ± 0.06 LogMAR. The monocular defocus curve was used to determine the range of focus achieved from distance (0.0D) to near above 0.2 LogMAR.  Photopic pupil size was split into three groups, 2.0mm to 2.99mm, 3.0mm to 3.99mm, and 4.0mm to 4.99mm, all achieving  between than 2.6 to 2.8D range of focus (38-36cm). Pre-op corneal spherical aberration (Z4,0) was split into three groups, 0.00µm to 0.19µm, 0.20µm to 0.39µm, and 0.40µm to 0.59µm showing a consistent range of focus across the three groups, all achieving between than 2.6 to 2.8D range of focus (38-36cm).

Conclusions

These results show that the RayOne Galaxy IOL with a spiral optic achieves good refractive predictability and a full range of focus. The new spiral optic maintains a full range of focus across varying photopic pupil sizes and varying levels of pre-op corneal spherical aberrations.
