Purpose
This analysis aims to present the visual and refractive outcomes and clinical defocus curve with the new spiral full range of vision intraocular lens (IOL). According to the manufacturer a proprietary AI engine created a unique optical spiral tuned for optimal patient outcomes. Spiral tracks allow continuous variance of power, focusing light at every position along the defocus curve producing a smooth and continuous full range of vision.
Setting
Ophthalmologikum Neuhann MVZ GmbH
Methods
A total of eighteen eyes from eleven patients (6 females, 5 males) were included in this ongoing single-center data collection. The implantation of the RayOne Galaxy intraocular lens (Rayner, UK) was performed due to cataract in 10 eyes of 7 patients, and refractive lens exchange (RLE) in 8 eyes of 4 patients between August and October 2024. Postoperative evaluations were conducted at one and three months, assessing manifest mean refractive spherical equivalent (MRSE), monocular uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), uncorrected near visual acuity (UNVA) and distance corrected near visual acuity (DCNVA) at 40cm. A preliminary monocular defocus curve was measured at three months.
Results
At the time of abstract writing our preliminary results show a reduction in MRSE from 0.94±3.21 D preoperatively to -0.03±0.31 D at 1 month postoperatively, with 95% of eyes having an MRSE within ±0.5 D and 69% of eyes were within ±0.25 D of MRSE. Mean UDVA and CDVA were 0.05±0.13 logMAR and to -0.02±0.04 logMAR, respectively. The mean UNVA and DCNVA were 0.18±0.17 logMAR and 0.17±0.17 logMAR, respectively. At 3 months post-op the monocular corrected defocus curve showed a peak at 0 (distance) with a mean visual acuity (VA) of 0.00±0.00 logMAR. At -1.5 D defocus (~66 cm) the mean VA was 0.10±0.00 logMAR. At a defocus of -3.0 D (~33 cm) the mean VA was 0.38±0.08 logMAR. A VA of 0.2 logMAR or better was achieved from +0.50 D to -2.25 D.
Conclusions
Our preliminary results with the RayOne Galaxy showed excellent monocular distance and near visual acuities. The monocular defocus curve showed a smooth and continuous range of vision suggesting a high level of spectacle independent vision. We aim to present results from a bigger cohort at the ESCRS.
