Purpose
To compare the visual outcomes, contrast sensitivity, night vision quality, defocus curve performance, and quality of vision (QOV) of the Rayner Galaxy Spiral multifocal IOL (MFIOL) and the Tecnis PureSee extended depth of focus (EDOF) IOL in patients undergoing cataract surgery or refractive lens exchange. Given the optical design differences, it is expected that the Rayner Galaxy Spiral MFIOL will provide superior near vision, while the Tecnis PureSee EDOF IOL will offer a smoother defocus curve, better intermediate vision, and reduced dysphotopsia, with potential advantages in night vision performance.
Setting
Retrospective comparative study at private eye clinic in Belfast, UK
Methods
- Retrospective analysis comparing two IOLs in terms of:
- Binocular uncorrected distance (UDVA), intermediate (UIVA), and near visual acuity (UNVA).
- Defocus curve analysis to assess functional vision at various distances.
- Contrast sensitivity under photopic and mesopic conditions.
- Night vision quality assessment, including patient-reported difficulties with low-light conditions and glare sensitivity.
- Patient-reported dysphotopsia, spectacle independence, and overall quality of vision (QOV) assessments.
- Cohort:
- Rayner Galaxy Spiral MFIOL (n=7, 1 month data, expected n=50 3 month data ESCRS 2025)
- Tecnis PureSee EDOF IOL (n=58, 1 month data, expected n=50 3 month data by ESCRS 2025)
Results
- Binocular Mean Uncorrected Distance Visual Acuity (BIN UDVA):
- Rayner Galaxy Spiral: -0.06 ± 0.04
- Tecnis PureSee: -0.04 ± 0.06
- Binocular Mean Uncorrected Intermediate Visual Acuity (BIN UIVA):
- Rayner Galaxy Spiral: 0.02 ± 0.13
- Tecnis PureSee: 0.08 ± 0.09
- Binocular Mean Uncorrected Near Visual Acuity (BIN UNVA):
- Rayner Galaxy Spiral: 0.1 ± 0.06
- Tecnis PureSee: 0.24 ± 0.11
- Expected Further Analysis (Full 3-Month Data at ESCRS 2025):
- Defocus curve comparison across both IOLs.
- Contrast sensitivity analysis
- Night vision quality assessment, including glare, halos, and low-light visual performance.
- Dysphotopsia incidence and spectacle independence rates.
- Comprehensive QOV assessment, including subjective patient-reported clarity and functional vision.
Conclusions
- Rayner Galaxy Spiral MFIOL provides better near vision compared to the Tecnis PureSee EDOF IOL.
- Distance vision is comparable between both IOLs.
- Intermediate vision is slightly better in the Galaxy Spiral group than in the PureSee group.
- Quality of vision, night vision quality, and contrast sensitivity will be further assessed in the final dataset, providing additional insights into patient-perceived optical quality and visual disturbances.
