Purpose
To evaluate the visual performance and defocus curve characteristics of a new refractive multifocal IOL (MIOL) with a spiral optic.
Setting
All surgeries were / will be performed at the Breyer-Kaymak-Klabe Eye Surgery and Premium Eyes in Duesseldorf, Germany, member of the International Vision Correction Research Center (IVCRC.net) by one single surgeon (Breyer).
Methods
Twenty-four patients underwent bilateral implantation of the Rayner Spiral Galaxy IOL (Rayner) during cataract surgery. Postoperative visual outcomes, including uncorrected and best-corrected distance, intermediate, and near visual acuities, were assessed. Defocus curve analysis (binocular uncorrected and monocular corrected) was performed to evaluate functional vision. Follow-up measurements were recorded three months postoperatively. The presence of photic phenomena was examined with the Halo & Glare Simulator (Zeiss) and quantified with the McAlinden Quality of Vision Questionnaire. Patient satisfaction and spectacle independence for distance, intermediate, and near were assessed with the McAlinden patient satisfaction survey.
Results
All patients achieved excellent uncorrected distance visual acuity, with a well-preserved range of functional vision at intermediate and near distances. Defocus curve analysis demonstrated a smooth and continuous transition of visual acuity, with minimal loss of quality across all distances. The majority of patients reported no or occasionally mild photic phenomena; severe glare, halo, starburst, blurred or fluctuating vision, and distortions were rare or absent. Most patients rated their quality of vision as good to very good at all distances, and at least around 95% no longer needed glasses for everyday activities, including reading a book and working at PC distance. Overall patient satisfaction was high.
Conclusions
The Rayner Spiral Galaxy MIOL provides excellent visual outcomes with a stable and well-balanced defocus profile. Quality of vision, reduced photopic phenomena and better contrast vision in comparison to classic diffractive MIOL make it a highly interesting alternative especially for patients who are driving at night time
