Purpose

To assess visual performance, contrast sensitivity, quality of vision, and dysphotopsias following implantation of the Rayner Galaxy Spiral IOL in a private practice setting. This study evaluates early (1-month) and mid-term (3-month) outcomes to determine the effectiveness of this novel IOL in providing functional vision across multiple distances.

Setting

Single-center prospective trial at private clinic in Belfast

 

 

Methods

 

  • Study Design: Prospective clinical study assessing:
    • Uncorrected distance visual acuity (UDVA), near visual acuity (UNVA), and intermediate visual acuity (UIVA).
    • Quality of vision metrics, including contrast sensitivity and defocus curve analysis.
    • Patient-reported satisfaction and dysphotopsia symptoms.
  • Patient Cohort:
    • Interim Analysis (1 month, n=7 patients, 14 eyes).
    • Final Dataset (3 months, n=40 patients) to be presented at ESCRS 2025.
  • Analysis: Statistical evaluation of visual function, contrast sensitivity, spectacle independence, quality of vision and defocus curve analysis

Results

Results (Interim 1-Month Data, n=7 patients, 14 eyes):

  • Distance Vision mean Binoc UDVA): -0.06 ± 0.04 logMAR.
  • Intermediate Vision mean (Binoc UIVA): 0.02 ± 0.13 logMAR.
  • Near Vision mean (Binoc UNVA): 0.1 ± 0.06 logMAR.
  • Patient-reported outcomes:
    • High patient satisfaction with early postoperative vision.
    • Minimal dysphotopsia complaints.

 

Expected Final Data (ESCRS 2025, n=40 patients):

 

Conclusions

The Rayner Galaxy Spiral IOL demonstrated excellent early visual outcomes, with high-quality distance, intermediate, and functional near vision at 1-month post-op. Minimal dysphotopsia and high patient satisfaction further support its potential as a premium IOL choice. The final 3-month dataset (40 patients) will provide more detailed insights into contrast sensitivity, defocus curves, and quality of vision, to be presented at ESCRS 2025.
