Purpose

Prospective Interventional case series to investigate visual and refractive outcomes of  patients receiving a new full range of vision spiral Intraocular lens  (Rayone Galaxy, Rayner Intraocular Lens LTD- United Kingdom)

Setting

RB Vision,  Buenos Aires , Argentina.  Patients who underwent bilateral phacoemulsification surgery  were enrolled.  Outcomes measures:  Visual (at long, intermediate and near distance) and refractive outcomes, photic phenomena and pupil decentration.

Methods

Twenty four eyes of twelve patients (16 spherical and 8 toric Galaxy IOLs)  were included.  A thorough ophthalmic examination was carried out  in each patient, including ARM, UDVA, slit lamp  and fundus examination, optical biometry, mesopic pupillometry,  topography (Topcon Aladdin) ), specular microscopy  (Topcon SP-1P),  and macular and fiber OCT  (Topcon Maestro 2).  Inclusion criteria  was patients presenting cataract.  Exclusion criteria  was cognitive deficit preventing patients from reading.   Distance , intermediate and near vision  were evaluated at 300 cm, 60 cm and 40 cm respectively (Precision Vision Chart) .  IOL calculations were obtained with the  Raytrace  web platform, aiming a post operative target form -0.19 to + 0.50.

Results

All surgeries were performed uneventfully.  Mean preoperative SE was 1.77 diopters SD 2.15 (mean sphere 2.18 SD 2.10, mean cylinder -0.83 SD 0.91) .  Mean postoperative SE was -0.52 diopters  SD 0.52 (mean sphere -0.38 SD 0.46, mean cylinder -0.47 SD 0.55).  Mean preoperative UDVA was  0.5 SD 0.3 LogMar.  Mean postoperative UDVA was 0.05 SD 0.07 LogMar.  Intermediate and near UVA were 0.0 LogMar in all eyes at seven days post op.  No correlation was found with regards to pupil centration (MU CHORD: mean values x -0.017 SD 0.27 y -0.06 SD 0.18 ) and postoperative UDVA.  Photic phenomena were inquired  actively, no patient reported halos and only  4 of 12 patients reported a pink hue peripherally which disappeared within seven days. 

Conclusions

The RayOne Galaxy IOL designed with a unique non diffractive spiral optic provides excellent visual outcomes, minimal photic phenomena and apparent pupil independence in relation to IOL centration.  A higher N of cases should be evaluated for further confirmation of these findings and patient reported outcome mesures should be collected to better comprehend visual disturbances.
